DIY Driveway Tutorial | ConcreteMaths.com

The complete UK guide to planning, designing, and installing your own driveway — covering planning permission and SuDS drainage rules, all five major surface types (concrete, block paving, tarmac, gravel, and resin-bound), step-by-step installation for each material, edging, drainage, cost guide, and maintenance. Updated for 2026 regulations.

2025–2026 UK Driveway Regulations — SuDS, Permitted Development & Planning

Under theTown and Country Planning (General Permitted Development) (England) Order 2008 (as amended), front garden driveways over 5 m² using impermeable (non-porous) materials require planning permission. Permeable surfaces (resin-bound, gravel, permeable block paving) or any driveway draining to a soakaway or lawn are exempt from planning permission under permitted development rights. NewNational Standards for SuDS 2025require most new surfaces to retain at least 5mm of rainfall on-site before discharge. Always confirm your specific position with your Local Planning Authority (LPA) before starting.

Planning Permission, Permitted Development & Legal Requirements

The Core Permitted Development Rule (England)

In England, you can install a front driveway without planning permission under Permitted Development Rights (PDR) provided the surface material ispermeable (porous), OR the surface drains to a permeable area (garden/soakaway) within the property boundary. If you want to use animpermeable surface(standard tarmac, solid concrete, non-permeable block paving) and the total area exceeds 5 m² in the front garden, youdo need planning permission. [web:108]

Any permeable surface (resin-bound, gravel, permeable block paving, grasscrete); any surface of any material draining to a lawn or soakaway within the property; rear driveways and parking areas not visible from the highway; any driveway under 5 m² regardless of material. [web:108][web:81]

Conservation areas; listed buildings (any external works require Listed Building Consent); Article 4 Directions removing PDR in specific streets; homes converted from commercial buildings via PDR; flats and maisonettes (PDR does not apply). [web:90]

Impermeable front driveway over 5 m²; new vehicle access crossing (dropped kerb) — separate highways consent required from the Local Highways Authority (LHA), not the LPA; any driveway in a Conservation Area using any hard material. [web:84][web:90]

SuDS — Sustainable Drainage Systems (2025 National Standards)

The 2025 National Standards for SuDS require that new hard surfaces must manage surface water sustainably — retaining a minimum of 5mm of rainfall on-site through infiltration, storage, or reuse before discharge to public sewers. [web:122] In practice for domestic driveways, this means:

Permeable surfacing preferredresin-bound, gravel, permeable block paving, or grasscrete pass water through to the sub-base and into the ground, fulfilling SuDS requirements without additional drainage infrastructure [web:81]
Impermeable surfacesrequire water to be directed to a soakaway, infiltration trench, or rain garden on the property — not directly to the public sewer or highway drain [web:81][web:124]
Minimum 1:60 fall(1.67% gradient = 17mm drop per metre) away from buildings and towards the drainage point. For driveways that slope toward the house, a linear channel drain must be installed at the foot of the slope to intercept water before it reaches the building [web:81]

Scotland, Wales & Northern Ireland — Separate Rules Apply

Scotland, Wales, and Northern Ireland each have their own planning legislation and permitted development rules for driveways — which differ from England in important ways. In Wales, the 5 m² impermeable surface rule also applies but there are additional SuDS requirements under the Flood and Water Management Act as implemented in Wales. Always contact your LPA or local council planning department before beginning any driveway installation outside England.

Dropped Kerb — Application, Costs & Process

If you are creating a new vehicle access point from a public road to your property — or widening an existing one — youmust apply for a dropped kerb (vehicle crossover)from your Local Highways Authority (LHA). This is a separate process from planning permission and is mandatory regardless of whether your driveway itself requires planning permission. Driving a vehicle across the pavement without a properly constructed dropped kerb is illegal and can result in enforcement action. [web:130]

Dropped Kerb Application Process

Check Eligibility & Suitability

Your LHA will assess whether a dropped kerb is feasible at your location — considering sightlines, proximity to junctions (typically 15m minimum), bus stops, trees, utilities, and other highway features. Contact your local council highways department for a pre-application suitability check before paying any fees.

Submit the Application & Pay the Fee

Apply via your local council’s highways or transport department — find the application portal via gov.uk/apply-dropped-kerb. Application (processing) fees range from£50–£430depending on the council — this fee is non-refundable even if the application is refused. [web:128][web:129]

Council Survey & Design

The LHA carries out a technical survey, checks for underground utilities, and produces a design for the dropped kerb. This typically takes 4–12 weeks depending on the authority’s workload.

Approved Contractor Installs the Kerb

Most councils require the physical kerb works to be carried out bycouncil-approved contractorsworking in the public highway. In some areas the council does the work itself. You typically cannot carry out dropped kerb works in the public highway yourself. Total cost (application + construction):£800–£3,000depending on location and complexity. [web:131][web:128]

Council Inspection & Sign-Off

An inspector from the LHA checks the completed works before the site is released. An inspection fee of approximately £200 is common. Only after sign-off can the driveway be used as a vehicle access.

Never Build a Driveway Without an Approved Dropped Kerb

Using a vehicle crossing over an unmodified or illegally modified kerb causes damage to the highway and footway, for which you as the property owner can be held liable for repair costs. The council can also require you to reinstate the footway and kerb at your own expense, plus enforcement penalties. Always obtain full dropped kerb approval before installing the driveway — allow 8–16 weeks for the full process.

Driveway Surface Materials — Complete Comparison

Choosing the right surface material is the most important decision in any driveway project. Each material has different cost, durability, maintenance, appearance, and planning implications. follow each material card to expand full details, pros/cons, and installation overview.

Block Paving

Concrete or clay blocks in herringbone, basketweave, or stretcher bond — the UK’s most popular driveway choice

Why Choose Block Paving?

Block paving is the most versatile and repairable driveway surface available. Individual blocks can be lifted and relaid to access services below — then put back without any visible repair. The wide range of colours, sizes (standard 200×100×65mm or 200×100×80mm for driveways), and laying patterns allows enormous design flexibility. Concrete blocks are more cost-effective; clay/brick blocks offer superior colour retention and a more premium appearance.

Pros

Fully repairable — individual blocks replaced without patching
Wide design variety — colours, sizes, patterns, borders
Permeable options (permeable block paving) available — no planning permission required [web:81]
Very durable — properly installed block paving outlasts most other surfaces
Adds kerb appeal and property value

Cons

Higher cost than tarmac or gravel — more time-consuming to lay DIY
Standard (non-permeable) block paving over 5 m² in front garden requires planning permission [web:108]
Weeds can grow in joints if kiln-dried sand or polymeric sand is not used and refreshed
Can sink in soft spots if sub-base is inadequate

Key Installation Notes

150mm compacted MOT Type 1 sub-base minimum for domestic cars [web:118]
30–40mm sharp sand (not building sand) bedding layer — screeded level [web:120]
Herringbone pattern at 45° or 90° provides maximum interlock and load distribution — recommended for driveways [web:116]
Edge restraints essential at all free edges — concrete haunching or proprietary plastic/aluminium restraint [web:134]
Compact with plate compactor after laying, fill joints with kiln-dried sand, re-compact, top up sand [web:118]

Tarmac / Asphalt

Hot-mix bituminous macadam — fast to install, cost-effective, and long-lasting. The professional’s choice for large areas.

Why Choose Tarmac?

Tarmac (hot-mix bituminous macadam) is the fastest to install and one of the lowest-maintenance driveway surfaces. Machine-laid tarmac by a professional contractor gives a consistently smooth, dense surface in a single day for most domestic driveways. Standard tarmac is impermeable — over 5 m² in the front garden requires planning permission unless drainage runs to a soakaway. [web:108]

Pros

Fast installation — typical driveway done in one day by a contractor
Cost-effective for larger areas
Very low maintenance — sweep and resealing every 5–7 years
Good freeze-thaw resistance when properly installed
Easily extended or repaired — new tarmac bonds to old

Cons

Standard tarmac is impermeable — planning permission needed over 5 m² in front garden [web:108]
Hot-mix tarmac requires professional equipment (paver machine, heavy roller) — genuine DIY is very difficult [web:132]
Black colour absorbs heat — soft in very hot weather (above ~35°C) can mark under vehicle jacks
Limited aesthetic variety — though coloured chipping or decorative tarmac available

Key Installation Notes

Sub-base: 150–200mm compacted MOT Type 1 [web:80]
Binder course (base course): 50–60mm hot-mix DBM (dense bitumen macadam) compacted — provides the structural strength [web:132][web:135]
Wearing course (surface course): 25–40mm 6mm aggregate hot-mix, machine laid and roller compacted [web:135][web:137]
Total finished tarmac depth: 70–100mm (binder + wearing course) [web:107]
Must be laid hot (105–145°C) and compacted immediately — cold-lay tarmac bags from builders’ merchants are for patching only, not full driveway installation [web:135]

Gravel / Loose Stone

Angular or rounded decorative gravel — the easiest DIY driveway surface and the cheapest to install.

Why Choose Gravel?

Gravel is permeable by nature — no planning permission required for front driveways. It is the cheapest driveway option per m² and the most accessible for DIY installation. Angular gravel (20mm granite, flint, or limestone) compacts better underfoot and under vehicles than smooth rounded pea gravel. Stabilising grids (plastic cellular grids) can be used beneath the gravel to prevent spreading and reduce gravel migration onto lawns and roads.

Pros

Cheapest installed cost of all driveway surfaces [web:112]
Permeable — no planning permission for front driveways, SuDS compliant [web:81]
Easy DIY installation — no specialist equipment needed
Security benefit — audible crunching sound deters intruders
Easy to repair and add to — just spread more gravel

Cons

Gravel migrates — needs raking back regularly and annual top-up
Loose surface is not ideal for wheelchairs, prams, or high heels
Weeds can grow through without a proper weed membrane
Can be scattered by spinning wheels or vehicle turning
Not suitable for steep driveways — gravel will wash or roll down slope

Key Installation Notes

Excavate topsoil to 200mm depth; lay geotextile weed membrane on sub-grade [web:76]
Install 100–150mm compacted MOT Type 1 sub-base [web:76]
Install second geotextile between sub-base and gravel — prevents intermixing [web:76]
Install edge restraints (timber, steel, concrete kerb, or proprietary plastic edging) before spreading gravel
Spread decorative gravel at 50–75mm depth — 20mm angular granite or flint recommended for vehicles [web:76]
For vehicle areas, consider plastic stabilising grids (Gravelrings, Gravelpave) which hold gravel in individual cells and prevent displacement

Resin Bound

UV-stable polyurethane resin mixed with natural aggregate — porous, smooth, and available in a huge range of colours.

Why Choose Resin Bound?

Resin-bound surfacing is the premium modern choice for UK driveways — fully porous (SuDS compliant, no planning permission), UV-stable, smooth underfoot, weed-resistant, and available in dozens of natural aggregate colours and blends. It is laid onto a solid existing base (concrete or tarmac) or a new concrete/tarmac base, making it popular for resurfacing existing driveways. The working window after mixing is only 10–30 minutes — speed and preparation are critical for DIY installation. [web:121][web:123]

Pros

Fully porous — permeable to water, SuDS compliant, no planning permission for front drives [web:81]
Enormous colour choice — natural aggregates, marble chippings, coloured glass blends
Smooth, hardwearing, weed-resistant surface
Seamless finish around curves and irregular shapes
Low maintenance — occasional pressure washing

Cons

Requires a sound existing base — cannot be laid on loose or cracked surfaces
Short working window after mixing (10–30 minutes) — DIY requires good team coordination [web:121][web:123]
More expensive than tarmac or gravel for supply
Must be laid in dry conditions — moisture on the base or in the aggregate prevents curing
Repairs are visible — patching after damage is difficult to disguise

Key Installation Notes

Base must be structurally sound concrete or tarmac — minimum 50mm tarmac or 100mm concrete on 150mm compacted sub-base [web:121]
Base must be completely dry — do not lay in rain, damp, or frost conditions [web:121]
Prime the base with polyurethane primer before mixing — allows 30–60 minutes for primer to tack off [web:126]
Mix resin Part A + Part B thoroughly, add pre-dried aggregate, mix until all stone is coated [web:121]
Lay at minimum 15–18mm depth (typically 18mm for driveways) using a squeegee and hand trowel [web:123]
Use UV-resistant (aliphatic) resin — avoid aromatic resin which yellows in sunlight [web:126]

Concrete Driveway

C25/30 reinforced slab — the most durable and lowest-maintenance driveway surface over its lifetime.

Why Choose Concrete?

A properly installed reinforced concrete driveway is the most durable and longest-lasting surface available — outlasting tarmac and block paving significantly with minimal maintenance. Standard concrete is impermeable — planning permission required over 5 m² in the front garden unless drainage goes to a soakaway. For DIY, concrete is very achievable for homeowners familiar with formwork, ordering ready-mix, and basic screeding. See the dedicated Concrete Base guide for full specification detail.

Pros

Longest lifespan of all driveway surfaces — 30–50 years with proper maintenance
Extremely low maintenance once cured — no resealing or top-dressing required
Can take decorative finishes — exposed aggregate, brushed texture, pattern imprinting
Excellent load-bearing — ideal for heavy vehicles, motorhomes, caravans

Cons

Standard concrete is impermeable — planning permission required over 5 m² in front garden [web:108]
Cracking is common if expansion joints are not correctly placed or sub-base is inadequate
Oil stains and salt staining can be difficult to remove
Typically lighter colour — shows dirt more than tarmac
Cannot be de-iced with rock salt — causes surface scaling

Key Specification

Concrete grade: C25/30 minimum for domestic driveways; C32/40 for heavy vehicles [web:76]
Slab thickness: 100mm for standard cars; 150mm for heavy vehicles [web:76]
Reinforcement: A252 mesh at mid-depth on 50mm plastic chairs
Sub-base: 150mm compacted MOT Type 1 on DPM and sand blinding
Expansion joints at maximum 4m spacing — Flexcell foam or saw-cut to 25% depth within 24 hours
Surface finish: brushed/broom finish for slip resistance on external slopes

Pattern Imprinted Concrete (PIC)

Stamped and coloured concrete — the appearance of block paving or stone at a lower installed cost than real block paving.

Pattern imprinted concrete (PIC) — also called stamped concrete — is a standard concrete slab that is coloured with integral pigment and surface hardener, then stamped with a patterned template while still plastic to create the appearance of brick, block, slate, or cobblestone. A sealer is applied once cured to enhance colour and protect the surface. It is impermeable (planning permission required over 5 m²) and requires professional installation due to the critical timing window for stamping.

Pros

Appearance of premium stone or block at lower cost than real stone
Wide pattern and colour choice
Single slab — no individual blocks to sink or shift
Easy to clean — pressure washing with sealer reapplication every 3–5 years

Cons

Sealer must be reapplied every 3–5 years — neglect causes colour fading and surface deterioration
Cracking visible — any crack cannot be repaired invisibly
Impermeable — planning permission required over 5 m² in front garden
Professional installation strongly recommended — timing of stamping is critical and DIY errors are permanent

Step 1 — Site Preparation & Excavation

Setting out, utility checks, excavation, and spoil removal — the foundation of everything.

Good site preparation is the most important factor in a driveway’s long-term performance. More driveways fail from inadequate preparation than from any other cause — sinking, cracking, and surface deterioration almost always trace back to poor excavation or sub-grade assessment.

Before You Start — Essential Pre-Checks

Call before you dig:ContactLSBUD (linesearchbeforeudig.co.uk)to request utility cable and pipe plans for your property. Carry out a CAT (Cable Avoidance Resource) scan before any excavation. Services can be shallower than you expect — BT ducting at 350mm, water at 750mm, gas at 600mm, electricity at 450mm are guidance only, not guarantees
Planning and dropped kerb approval:Confirm all approvals are in hand before spending a penny on materials
Assess existing surface:If removing an existing tarmac or concrete driveway, this is typically the largest cost and waste disposal element — hire a skip (6–8 yard) and book it before starting. A 6×3m tarmac drive generates approximately 3–4 tonnes of break-out material
Mark out the exact perimeterwith spray paint on the existing surface — include 150mm working room outside the finished edge on all open sides for formwork or edging installation

Material: Concrete; Surface Depth: 100–150mm slab; Bedding / Base: 25–50mm blinding; Sub-Base: 150mm Type 1; Total Excavation: ~275–350mm

Excavation Procedure

Remove all topsoil, turf, and vegetation from the entire area. Topsoil must be completely removed — it is organic, compressible, and will cause settlement
Excavate to formation level (underside of sub-base). On a sloping site, step excavation to maintain a consistent sub-base depth across the full area
Assess the exposed sub-grade: walk over it, probe with a steel bar. Any soft or spongy areas must be over-excavated and replaced with well-compacted MOT Type 1. Never leave soft spots beneath any load-bearing surface
If tree roots are encountered, cut cleanly with a pruning saw — do not rip with the excavator bucket. Treat cut root ends and consult an arborist if large roots (over 50mm diameter) are severed near significant trees
Compact the exposed sub-grade with a plate compactor before placing any sub-base material — at least two passes in perpendicular directions
Dispose of all excavated material responsibly — topsoil to a skip or arrange a grabber lorry collection. Do not bury topsoil on site beneath the sub-base

Spoil Disposal — Skips and Waste Carrier Licensing

Excavated material is classified as construction waste. It must go to a licensed waste transfer or recycling facility — it cannot legally be taken to your local tip in a car boot in commercial quantities, tipped on land without an environmental permit, or fly-tipped. Budget for a 6-yard skip at approximately £220–£350 depending on your region, or hire a grab lorry for larger volumes. Keep your skip off the public highway if possible — if it must go on the road, you need a skip permit from your local council (typically £40–£80).

Step 2 — Sub-Base Installation (MOT Type 1)

The structural foundation layer — gets this right and everything above will last.

The sub-base is the single most important structural element of any driveway. It distributes the load from vehicles across the sub-grade, provides a stable working platform, and prevents settlement. The correct material isMOT Type 1 crushed limestone or granite(also called DTp Type 1 or road base) — a well-graded angular crushed stone that compacts into a dense, stable layer. Do not use Type 2 (rounded material), MOT Type 3 (open-graded, for permeable drainage), or recycled/crushed concrete unless specifically approved for driveway use.

Surface Layer

Block paving / tarmac / resin / concrete / gravel — the finished surface you walk and drive on

Bedding Layer

30–40mm sharp concreting sand (block paving) or DPM/blinding (concrete) — fine-levelling bed

MOT Type 1 Sub-Base

Compacted crushed limestone/granite — the primary structural layer distributing vehicle loads

Geotextile Membrane

Separating membrane — prevents sub-grade fines migrating into sub-base over time

Compacted Sub-Grade

Natural ground — excavated, assessed, and compacted before sub-base placement

Sub-Base Installation Procedure

Lay geotextile separation membraneover the compacted sub-grade — overlap all joints by minimum 300mm. Pin edges with U-shaped steel pins. This prevents the clay or silty sub-grade pumping up into the Type 1 over time under load
Spread MOT Type 1 in layers no deeper than 100mm per passdo not spread the full 150mm depth in one go, as the bottom of a thick layer will not compact properly. For 150mm total, do two passes: 75mm + 75mm, compacting each before adding the next
Level each layer roughly with a rakebefore compacting — aim for a consistent depth across the area. Check levels with a straight edge and spirit level, maintaining the designed surface fall (minimum 1:60 away from buildings)
Compact each layer thoroughly with a plate compactorminimum 3 passes in one direction, then 3 passes at 90°. The Type 1 should feel firm and non-yielding underfoot after compaction. Any soft or bouncy spots indicate inadequate compaction or a soft sub-grade beneath
Check the final compacted levelagainst your level pegs and string lines. The finished top of sub-base should be exactly the depth of your bedding layer + surface material below the required finished driveway level
Protect completed sub-basefrom rain before laying the surface — well-compacted Type 1 is relatively stable when wet, but avoid trafficking it with loaded wheelbarrows over newly compacted surface unnecessarily

How Much MOT Type 1 to Order

MOT Type 1 compacts by approximately 20–25% from loose to compacted volume. To achieve 150mm compacted depth over 18 m² (6m × 3m driveway): uncompacted volume = 18 × 0.150 × 1.25 = 3.375 m³. Round up to 3.75–4 m³ to allow for waste and uneven sub-grade. Most suppliers sell in 0.5 m³ bags or bulk loose loads — for larger driveways, a 4–6 tonne bulk loose tip is significantly cheaper per tonne than bulk bags. 1 tonne of MOT Type 1 ≈ 0.65 m³ loose ≈ 0.52 m³ compacted.

Step 3 — Edging & Edge Restraints

Contain the surface, define the boundaries, and prevent lateral spreading — essential for all driveway types.

Edge restraints prevent the surface material spreading laterally under vehicle load and the freeze-thaw action of winter. Without adequate edging, block paving fans out at the edges, gravel migrates onto the lawn, and tarmac edges crumble and break away. Install edging before the surface layer and after the sub-base is complete and compacted.

Edging Types by Material

Edging Type: Concrete Kerb (10×15cm); Best For: Block paving, concrete, tarmac — formal driveway edges adjoining grass or borders; Installation Method: Haunched on concrete backing (C20 mix, 150mm wide × 100mm deep haunch each side); Cost (approx.): £4–£8/m material; £20–£40/m installed
Edging Type: Proprietary Plastic Edging (EasyEdge, Pavetuf); Best For: Block paving, gravel, resin bound — flexible curved edges; Installation Method: Hammered into compacted sub-base with 200mm steel pegs at 500mm spacing; Cost (approx.): £3–£8/m material
Edging Type: Steel Lawn Edging; Best For: Gravel, resin, decorative borders — clean modern aesthetic; Installation Method: Driven into sub-base or pegged with supplied stakes; good for curves; Cost (approx.): £8–£18/m material
Edging Type: Aluminium L-Section; Best For: Resin bound, block paving — particularly at transitions to paths and other surfaces; Installation Method: Screwed to concrete base or haunched with mortar; Cost (approx.): £6–£14/m material
Edging Type: Concrete Haunching (Block Paving); Best For: Block paving — the strongest and most permanent edge restraint for vehicle driveways; Installation Method: C20 concrete placed against pre-installed edging kerb or directly against the last course of blocks — 150mm wide, angled back at 45° from the block face; Cost (approx.): £2–£4/m (materials only)
Edging Type: Sawn Natural Stone; Best For: High-end block paving or resin — contrasting border course; Installation Method: Laid on 30mm mortar bed on concrete foundation — as a soldier course border; Cost (approx.): £25–£60/m installed

Key Edging Rule — Level and Locked Before You Start the Surface

All edging must be installed, level-checked, and fully set (concrete haunching cured for minimum 24 hours) before the surface layer is installed. Attempting to lay block paving up to an unfixed or uncured edge will result in the edge moving under load during laying — wasting time and potentially requiring re-laying sections. On block paving jobs, string lines from the set edging provide the level datum for the sand bed and subsequent paving courses.

Step 4 — Drainage Design & Installation

Surface water management — the most commonly overlooked element, and the one most likely to cause problems if missed.

Every driveway must have a drainage strategy. Water that ponds on a driveway surface causes surface deterioration, slab heave in winter, and — if it runs toward the building — potential damp ingress and flood risk. The 2025 SuDS National Standards require new surfaces to manage the first 5mm of rainfall on-site before discharge.

Drainage Options for UK Driveways

Surface Fall to Garden / Lawn

The simplest and most SuDS-compliant option. Design the driveway with a minimum 1:60 crossfall (17mm/m) directing water off the edge onto an adjacent lawn, border, or soakaway area. No additional drainage infrastructure required. Works well for most domestic driveways with an adjacent permeable area.

Soakaway / Infiltration Trench

A soakaway pit (typically 1m × 1m × 1m, filled with clean angular stone) or infiltration trench receives surface water from the driveway via a channel drain. Must be located minimum 5m from any building and in permeable ground — carry out a percolation test (BS EN ISO 22282) before installation to confirm the ground will accept the water.

Channel / Linear Drain

A aco or similar channel drain installed across the foot of a slope or at the building threshold intercepts surface water and directs it to a soakaway, rain garden, or (with SuDS attenuation) the surface water sewer. Essential for any driveway that slopes toward the house. Standard aco channel: 100mm or 150mm wide, HDPE or SABS concrete body.

Rain Garden / Swale

A shallow planted depression adjacent to the driveway that receives and absorbs surface water runoff — fully SuDS compliant and wildlife-friendly. Planted with flood-tolerant species (Iris, Juncus, Carex). Requires a ponding depth of 100–200mm and a planted area approximately 20–30% of the driveway area. Increasingly popular and supported by many local councils.

Permeable Surface (Inherent Drainage)

Resin-bound, permeable block paving, gravel, and grasscrete allow rainwater to pass directly through the surface into the sub-base and sub-grade. The sub-base acts as a temporary storage reservoir, releasing water slowly into the ground. The most practical and planning-friendly drainage solution for front driveways — no separate drainage infrastructure required.

Surface Water Sewer Connection

Connecting driveway drainage to the public surface water sewer requires approval from the sewerage authority (typically Water Company consent or building regulations approval). Never connect driveway drainage to the foul (black water) sewer — this is illegal under the Water Industry Act 1991 and can result in significant fines. Always confirm which sewer is available at the point of connection.

Channel Drain Installation (Linear Drain at Building Threshold)

Set out the channel at right angles to the direction of flow — typically across the full width of the driveway at the threshold of the house or where the slope changes direction toward the building
Excavate a trench 150mm wider than the channel body and 100mm deeper than the required invert level
Lay C20 concrete bed (100mm) in the trench bottom; position the channel body on the wet concrete and check level — the channel grate surface must be 3–5mm below the surrounding driveway surface to encourage water to enter
Haunch both sides of the channel body with C20 concrete; leave to cure 24 hours before backfilling
Connect the channel outlet to the drainage run (100mm HDPE pipe at minimum 1:80 gradient to the soakaway or sewer connection)
Install the channel grate (heavy duty ductile iron grate for vehicle areas — rated minimum C250 kN for domestic vehicles) and check it is secure and flush with the finished surface level

Step 5 — Block Paving Installation

Step-by-step block laying, cutting, jointing, and compaction for a herringbone driveway.

Sand Bedding Layer

Lay 30–40mm sharp concreting sand (not soft building sand — it is too fine and will not provide a stable bed) over the compacted sub-base. Do not compact the sand — it must remain loose to allow blocks to be bedded into it during laying and final compaction. Use 40mm diameter steel or aluminium screed rails (conduit pipe works well) set at the correct level to screed the sand perfectly flat. Pull a straight screed board across the rails to create a perfectly level bed, then carefully remove the rails and fill the grooves with sand.

Block Laying — Herringbone Pattern

Establish the starting point:For a 45° herringbone (recommended — provides maximum interlock and is visually the most appealing on rectangular driveways), snap chalk lines at 45° to the primary edge from the centre of the drive or from a defined datum. The 45° herringbone means cut blocks at all four edges — this is normal and expected
Lay from a fixed corner outward in a staircase patternnever from one edge across, as any cumulative error multiplies. Work from the already-laid blocks, kneeling on a kneeling board placed on the freshly laid blocks to avoid disturbing the sand bed
Place each block vertically downinto position — do not slide blocks across the sand bed as this displaces the screed and creates uneven depths. Each block should sit approximately 5–10mm above the finished level (the compaction process will bring them down)
Maintain consistent joint width:Standard blocks are manufactured with spacer nibs — these set the joint width automatically. If using blocks without spacers, use 2–3mm plastic tile spacers
Check levels regularly:Lay a long straight edge across the blocks every 10–15 blocks. All blocks should be within ±3mm of each other. Tap high blocks down gently with a rubber mallet; lift and add sand under low blocks
Cut perimeter blocks:Mark cuts with a pencil/chalk using the block as a template. Use a petrol or electric angle grinder with a dry diamond disc, or a hydraulic block splitter (hire). Always wear full PPE — safety glasses, dust mask (P3 for block cutting), ear defenders, gloves

Jointing, Compaction & Finishing

Once all blocks are laid and cut, sweep kiln-dried jointing sand across the entire surface and work it into all joints with a stiff brush
Make a final pass with the plate compactor (fit the rubber sole pad to protect block surfaces) across the entire area — this beds all blocks to the correct level and closes any uneven joints
Sweep more kiln-dried sand into the joints and compact again — repeat until joints are full and no settlement occurs during compaction
For long-term weed resistance, considerpolymeric jointing sand(e.g. Marshalls Drivesett, Rompox Easy) in place of standard kiln-dried sand — polymeric sand hardens on wetting and significantly reduces weed seed germination and ant activity in joints
Brush away all surplus sand from the block surface after the final compaction pass — surplus sand left on the surface will stain and harden
Do not open the driveway to vehicle traffic for minimum 24–48 hours after the final compaction to allow the sand bed to fully stabilise

Block Paving Quality Check — Before You Finish

Walk across the entire completed driveway and look for: rocking blocks (lift and add sand), open joints wider than 4mm (add more jointing sand and re-compact), edge blocks that protrude or sit low at the concrete haunching (check haunch level before laying), any cracked blocks (replace — cracked blocks will allow water ingress and accelerate failure). A well-laid herringbone driveway should look like a continuous carpet of blocks with uniformly tight joints and no rocking or movement underfoot.

Step 6 — Tarmac / Asphalt Installation

Professional hot-mix process overview — what to expect from a contractor and how to specify correctly.

Full hot-mix tarmac installation requires a professional contractor with a mechanical paving machine and heavy roller — it is not practically achievable as a DIY project for a standard driveway. However, understanding the correct process allows you to specify work correctly, recognise poor workmanship, and avoid being overcharged or undersupplied. The following is the correct professional installation sequence.

Professional Tarmac Installation Sequence

Sub-base preparation:150–200mm compacted MOT Type 1 — as described in Step 2. The paving machine needs a firm, level surface to run on. Check all edging and channel drains are installed and set at the correct final levels before tarmac laying begins
Binder course (base course) — 50–60mm DBM:Hot dense bitumen macadam (DBM) at 105–145°C, laid and machine-compacted to 50–60mm finished depth. This is the structural layer — the binder course takes the load and distributes it across the sub-base. It should be black, consistently even, and well-compacted with no roller marks remaining after final pass
Tack coat:A bituminous emulsion tack coat (spray applied) is applied to the binder course surface before the wearing course — this bonds the two layers together and prevents delamination under traffic loading
Wearing course — 25–40mm hot-rolled asphalt or SMA:The top layer (6mm aggregate wearing course or stone mastic asphalt) is machine-laid at 25–40mm depth. The wearing course provides the smooth, durable, weatherproof surface. It must be compacted while still hot — roller passes start at the edges and work toward the centre on cambered areas, or from low to high on crossfalled surfaces
Finished level check:Wearing course finished level should be flush with or 3–5mm below the surrounding kerbs, paths, and threshold level at the house. The surface fall should be a consistent 1:60 minimum toward the drainage point

Warning — Cold-Lay Tarmac from Builders’ Merchants

Cold-lay tarmac (sold in 25kg bags at DIY stores and builders’ merchants) is a bituminous patching compound — not a structural driveway surfacing material. It is suitable for filling individual potholes in an existing tarmac surface, but is not suitable for laying an entire new driveway. Cold-lay tarmac does not achieve the density, stability, or durability of properly compacted hot-mix tarmac — a cold-lay driveway will deform under vehicle loads, rut in warm weather, and break up within a few years. For a new tarmac driveway, always use a professional hot-mix contractor.

Step 7 — Gravel Driveway Installation

The most accessible DIY driveway — achievable in a weekend with basic resources.

Gravel Installation Step by Step

Excavate and compact sub-gradeas described in Steps 1 and 2 — 200–250mm total depth from finished surface level
Lay first geotextile membranedirectly on the compacted sub-grade — overlap all joints 300mm, fix with U-pins at 1m spacing. This prevents the sub-grade migrating into the Type 1 over time
Install 100–150mm compacted MOT Type 1sub-base — compact in two 75mm layers
Install edge restraintsaround the full perimeter before spreading gravel — concrete kerbs, timber baulks (100×75mm pressure treated), proprietary plastic edging, or decorative metal lawn edging. The top of the edging should be at or slightly above the finished gravel surface level to contain the gravel
Lay second geotextile membraneon top of the compacted sub-base — this separates the sub-base from the decorative gravel layer, preventing the gravel sinking into the Type 1 over time while still allowing drainage
If using stabilising grids(recommended for vehicle areas): interlock the plastic panels across the full area on top of the geotextile. The grid cells hold individual gravel pieces in position and dramatically reduce migration and spread under tyre loading
Spread decorative gravelat 50–75mm depth — tip and rake evenly across the area. For a standard gravel driveway (no grids), 50mm depth is the minimum for adequate coverage; 75mm provides a more solid feel underfoot and better coverage over time
Rake to a consistent leveland remove any oversized stones or debris from the surface. The finished gravel surface should be 10–15mm below the top of the edging restraints to prevent gravel spilling over onto adjacent surfaces

Choosing the Right Gravel

20mm angular granite or flint:Best for vehicle driveways — angular particles lock together under compaction providing more stability than rounded gravel. Grey granite, golden flint, or black basalt are popular choices
14mm angular gravel:Better for pedestrian areas — smaller particles feel more comfortable underfoot and provide a cleaner appearance
Avoid 10mm pea gravel for vehicle driveways:Rounded particles do not interlock — they spread easily under tyre pressure and are constantly tracked onto paths and lawns. Pea gravel is fine for garden paths, not vehicle areas
Quantity working:20 m² driveway at 50mm gravel depth = 20 × 0.05 = 1.0 m³ of gravel = approximately 1.8–2.0 tonnes. Add 10–15% for waste and uneven ground. 1 tonne bulk bag covers approximately 10–12 m² at 50mm depth

Step 8 — Resin Bound Driveway Installation

Porous, premium-looking surface — achievable DIY with the right equipment and meticulous preparation.

Resin-bound surfacing is the fastest-growing driveway surface in the UK — fully porous, SuDS compliant, and available in a remarkable range of colours. Successful DIY installation requires a forced-action mixer (not a standard drum mixer), good team coordination, and working in dry conditions above 5°C. The working life of mixed resin is only 10–25 minutes depending on temperature — plan every step before you start mixing.

Resin Bound Installation Step by Step

Prepare the base:The base must be structurally sound concrete or tarmac — minimum 50mm tarmac on 150mm Type 1, or 100mm concrete on 150mm Type 1. The base must be completely dry — surface moisture prevents resin curing. Allow minimum 48 hours after any rainfall before applying resin. Repair any cracks in the base with appropriate filler before application
Install edging:Aluminium angle sections or resin-compatible plastic edging installed and fixed at the correct finished level — the resin surface is trowelled flush with the top of the edging
Apply the primer:Roll UV-stable polyurethane primer onto the entire base area using a medium-pile roller. Allow 30–60 minutes for the primer to become tacky before applying the resin layer. Do not allow the primer to fully cure — it must be tacky when the resin is applied for good bonding
Prepare aggregate:The decorative aggregate must be kiln-dried to 0% moisture content. If using a pre-bagged kit, the aggregate is supplied pre-dried. If buying aggregate separately, dry in an oven or use a forced-action mixer with warm air to dry before use. Any moisture in the aggregate prevents curing and causes the mix to clump
Mix the resin:Combine Part A (resin) and Part B (hardener) in the forced-action mixer exactly as per the manufacturer’s instructions — typically 1–2 minutes of resin mixing before adding aggregate. Add aggregate gradually while the mixer is running until all stone is uniformly coated with resin — approximately 2–3 minutes total mixing time per batch
Lay the mix immediately:Tip the mixed resin-aggregate onto the primed base and spread with a stainless steel squeegee or trowel to 15–18mm depth. Work quickly — the clock is running from the moment Part A and Part B are combined. Trowel the surface smooth and flush with the edging, using a plasterer’s trowel for final finishing. Avoid over-working the surface — it should have a natural aggregate texture, not a polished finish
Allow to cure:Resin bound typically reaches walk-on strength in 4–6 hours and vehicle-strength in 24 hours. Do not allow traffic until fully cured. Protect from rain for minimum 4 hours after laying — cover with a temporary polythene tent if rain is forecast

Do Not Use a Standard Drum Mixer for Resin Bound

A standard rotating drum mixer (as used for concrete) does not coat resin-bound aggregate uniformly — the aggregate rolls around the drum without achieving the even coating required. Aforced-action mixer(paddle mixer, pan mixer) forcibly works the resin into all surfaces of the aggregate. Using a drum mixer produces an inferior mix with poorly bonded particles that will dislodge from the surface under foot and vehicle traffic. Hire a forced-action mixer — it is a non-negotiable requirement for resin bound installation.

Step 9 — Concrete Driveway Slab

Formwork, reinforcement, ready-mix ordering, pouring, finishing, and curing — the most durable DIY driveway surface.

Specification Summary

Concrete grade:C25/30 minimum for standard domestic cars; C32/40 for heavier vehicles, motorhomes, or lorry access
Slab thickness:100mm for standard cars on good ground; 150mm for soft ground or heavier vehicles
Reinforcement:A252 steel mesh (6mm bar at 200mm centres both ways) placed at mid-depth on 50mm plastic chairs
Sub-base:150mm compacted MOT Type 1; 1200-gauge DPM over sub-base; 25–50mm sharp sand blinding between DPM and mesh
Expansion joints:Maximum 4m spacing in each direction — Flexcell foam compressible filler board (or saw cut to 25mm depth within 24 hours of pour)
Surface finish:Brushed/broom finish (drag a stiff brush across the surface while still plastic) — provides essential slip resistance on the driveway slope
Surface fall:Minimum 1:60 away from buildings and toward the drainage point — set by the formwork levels

Concrete Driveway Pour — Step by Step

Erect formwork:Set 100×50mm (or 150×50mm for a 150mm slab) timber shuttering around the perimeter, supported by stakes driven into the sub-base at 600mm maximum spacing. Set levels carefully — the top of the formwork is the finished concrete level. Check all faces for plumb and all levels with a spirit level and builder’s line
Install DPM:Lay 1200-gauge polythene DPM over the sub-base and blinding, lapping up the inside faces of the formwork. Tape all DPM joints — the DPM prevents moisture migrating from the ground into the slab and also prevents the bleed water from fresh concrete being absorbed into the sub-base (which would reduce workability)
Install expansion joint material:Fix Flexcell compressible foam boards (same thickness as slab) across the slab at 4m centres, from the DPM to the top of the formwork. Secure with tape — they must be vertical and exactly at the correct spacing
Place reinforcing mesh:Lay A252 mesh on 50mm plastic chairs (bar chairs) across the full slab area. Lap mesh sheets by a minimum of one full mesh square (200mm). Tie laps with wire ties. The mesh should be at the mid-depth of the slab ± 20mm — for a 100mm slab, chairs at 50mm height
Order and receive ready-mix:Order C25/30 (or C32/40), 20mm aggregate, S3 slump (80–110mm) for a pumpable or normal workability mix. Specify ST4 or RC25/30 equivalent on the delivery ticket. A 6m × 3m × 100mm slab requires approximately 1.8 m³ — order 2.0 m³ to allow for waste. A standard truck holds 6–8 m³; a half-load (3–4 m³) attracts a part-load surcharge
Place concrete:Start at the far end from the truck discharge point and work back toward the truck. Spread concrete with a concrete rake — do not use a standard garden rake, which cannot move the aggregate evenly. Keep the mesh in position as you fill — do not allow the mesh to sink to the bottom under the weight of fresh concrete
Vibrate and compact:Use a poker vibrator (50mm head) inserted at 300–400mm intervals across the slab — each insertion for 5–10 seconds until air bubbles stop appearing at the surface. Poker vibration eliminates voids and ensures a dense, uniform slab. On small DIY pours, a vigorous rod (tamping bar) can substitute, though a poker produces better results
Screed and float:Pull the screed board (a straight 100×50mm board spanning the two formwork sides) across the surface in a sawing motion to strike off excess concrete and produce a flat surface. Follow with a bull float to close surface voids and produce an even texture before the final finish
Apply broom finish:Once the bleed water sheen has disappeared from the surface (typically 30–90 minutes after placing, depending on temperature), drag a stiff broom lightly across the surface in parallel lines perpendicular to the direction of vehicle travel. This creates a slightly rough texture for grip on slopes
Cure the concrete:Immediately after finishing, cover with 1000-gauge polythene sheet, weighted at all edges — or spray with a proprietary curing compound (spray-on membrane that retards evaporation). Minimum 7 days curing for C25/30 at above 15°C; extend to 10–14 days in cooler weather
Strike formwork:Remove formwork after minimum 3 days (summer) or 5–7 days (below 10°C). Do not open to vehicle traffic for minimum 7 days (summer) or 14 days (below 10°C)

Driveway Maintenance by Surface Type

Regular maintenance significantly extends the life of any driveway surface and preserves its appearance. The maintenance requirements vary considerably between surface types.

Surface: Block Paving; Annual Tasks: Sweep, pressure-wash with mild detergent, apply weed killer to joints, top up kiln-dried sand in joints; 5-Year Tasks: Re-sand joints with polymeric jointing sand; re-seal with penetrating block paving sealer; re-level any sunken areas; Avoid / Never Do: Rock salt / de-icer; pressure washing at high angle which blasts out joint sand; oil spills (clean immediately with cat litter then degreaser)
Surface: Tarmac; Annual Tasks: Sweep, remove weeds at edges, fill any cracks or potholes promptly with cold-lay bituminous compound; 5-Year Tasks: Apply tarmac rejuvenating sealer every 5–7 years — restores colour, flexibility, and weather resistance; Avoid / Never Do: Vehicle jacks on kickstands without spreader plates (dents the surface in hot weather); petrol or oil spills — clean immediately with sawdust and detergent
Surface: Gravel; Annual Tasks: Rake back spread gravel to level; remove blown leaves; pull weeds at edges; treat any weed breakthrough with glyphosate; 5-Year Tasks: Top up with fresh gravel (approximately 25mm every 5 years); inspect and re-pin geotextile membrane where exposed; Avoid / Never Do: Rock salt (causes limestone gravel to break down); petrol-powered leaf blowers which scatter gravel widely; mechanical sweeping machines
Surface: Resin Bound; Annual Tasks: Pressure wash (medium pressure) in spring and autumn; clear any algae with specialist porous surface cleaner; remove leaves promptly; 5-Year Tasks: Inspect for any loose aggregate or delamination; re-apply UV-stable sealer if surface appears dull. Specialist repair for any cracked areas; Avoid / Never Do: High-pressure washer that can dislodge surface aggregate; de-icing salt; using a rotary or turbo nozzle — use fan nozzle at medium pressure only
Surface: Concrete; Annual Tasks: Pressure wash annually; inspect expansion joints — re-fill with flexible sealant if cracked or open; treat any oil stains promptly with degreaser; 5-Year Tasks: Apply penetrating concrete sealer every 5–7 years — reduces staining and improves frost resistance; Avoid / Never Do: Rock salt / de-icing salt — causes severe surface scaling; acid cleaning products; allowing oil to soak in (clean within hours)

Oil Stain Removal — All Surfaces

Fresh oil is far easier to remove than set oil. Act immediately: pour dry cat litter or sawdust onto the spill and leave for 24 hours to absorb the oil. Sweep up the absorbent material, then apply a proprietary traffic film remover or driveway degreaser. Work in with a stiff brush, leave 10–15 minutes, then rinse with hot water. For older, set stains on concrete and block paving, a poultice of fuller’s earth and solvent applied and left for 24 hours before removal can draw the remaining oil out of the surface pores.

DIY Driveway — Frequently Asked Questions

The most commonly asked questions from UK homeowners planning a new driveway.

Not always. In England, you can install a front driveway without planning permission provided the surface ispermeable(water can pass through it), or the water drains to a permeable area within the property boundary (such as a lawn or soakaway). If you want to use an impermeable surface (standard tarmac, solid concrete, non-permeable block paving) and the driveway area in the front garden exceeds 5 m², then planning permission is required.

Permeable surfaces — no planning permission needed:resin-bound, gravel, permeable block paving, grasscrete
Impermeable surface under 5 m²:no planning permission needed
Impermeable surface over 5 m² in the front garden:planning permission required
Rear driveways:generally no planning permission required regardless of material
Conservation areas:additional restrictions apply — check with your LPA
Scotland, Wales, and Northern Ireland have separate rules — always check with your local planning authority

Installed costs (contractor supply and lay) for a typical 20 m² domestic driveway in 2025–26:

Gravel:£500–£1,300 (25–65/m²) — cheapest option
Tarmac:£1,000–£2,000 (50–100/m²) — good value for larger areas
Block paving (concrete blocks):£1,600–£3,000 (80–150/m²)
Resin bound:£1,200–£2,400 (60–120/m²)
Concrete slab:£1,600–£2,600 (80–130/m²)
Pattern imprinted concrete:£1,800–£3,200 (90–160/m²)
DIY installation reduces costs by 40–60% on block paving, gravel, and concrete by eliminating labour charges
Add £800–£3,000 for a dropped kerb if a new vehicle access is required

Yes — block paving is one of the most achievable DIY driveway surfaces for a competent homeowner. It requires no specialist equipment beyond a plate compactor (hire £50–80/day) and an angle grinder with a diamond blade for cutting
The key skills required are: setting out levels accurately with string lines, screeding a consistent sand bed, laying blocks in a consistent pattern with tight joints, and operating the plate compactor safely
A typical first-timer can lay approximately 5–8 m² per day working alone — a 20 m² driveway is a 3–4 day weekend project with help
Watch several detailed block paving videos before starting — the visual element of the block-laying and sand-screeding technique is difficult to convey in text alone
The most common DIY mistakes: inadequate sub-base depth (use 150mm not 100mm), using building sand instead of sharp sand for the bedding layer, not fitting concrete haunching or edge restraints, and not using polymeric sand in the joints (which leads to early weed growth)

Gravel driveway (20 m²):1–2 days for a competent DIYer — excavation day 1, sub-base and gravel day 2
Block paving (20 m²):4–6 days — day 1: excavation; day 2: sub-base and edging; day 3: sand bed and laying start; days 4–5: block laying and cuts; day 6: jointing, compaction, and clean-up
Concrete slab (20 m²):3–4 days — day 1: excavation and sub-base; day 2: formwork, DPM, mesh; day 3: pour and finish; days 4–14+: curing (no traffic)
Resin bound (20 m²):2 days — day 1: base preparation and primer; day 2: resin application. Plus 24 hours curing before vehicle use
Allow extra days for any sub-grade remediation, utility diversions, or bad weather delays. Never rush the sub-base preparation to save a day — it is the most important stage

Tarmac:Best choice for steep slopes — machine-laid tarmac can accommodate any gradient, is non-slip when properly finished with a textured surface, and has no loose elements that can migrate downhill
Block paving:Good on moderate slopes (up to 1:10 / 10%) — the interlocking blocks perform well on slopes if a herringbone pattern is used. On steeper slopes, blocks can creep downhill over time even with good edge restraints
Concrete:Excellent on slopes — a brushed finish provides slip resistance and the slab is fixed in place. Consider a channel drain at the base of the slope to intercept runoff
Gravel:Not suitable for slopes steeper than approximately 1:20 (5%) — gravel rolls and washes down slope under rain and vehicle loading
Resin bound:Can be used on slopes up to approximately 1:8 (12.5%) — the bound surface is fixed in place. Ensure adequate drainage at the base of any resin-bound slope
For any sloping driveway, always install a channel drain at the foot of the slope to prevent runoff reaching the house or public highway

150mm compacted MOT Type 1is the standard minimum for a domestic driveway carrying standard cars (up to 3.5 tonnes)
200mm compactedfor heavier vehicles (vans, 4×4s, motorhomes, caravans), soft or clay sub-grades, or areas that carry vehicles regularly
250mm+for commercial vehicle access, areas with very poor or waterlogged sub-grades, or where CBR (California Bearing Ratio) testing shows sub-grade bearing capacity below 3%
100mm is insufficient for vehicle drivewaysit may be adequate for pedestrian paths and light-use areas, but will settle under regular vehicle loading. Do not cut corners on sub-base depth — it is the cheapest part of the project relative to the cost of settlement and re-laying
Always lay sub-base in maximum 100mm compacted layers — never try to compact 150mm in a single pass with a plate compactor, as the bottom of the layer will not compact and will settle later

Resin bound over existing sound tarmac or concrete:Yes — this is the most common application for resin-bound surfacing. The existing surface must be structurally sound, free from significant cracking, and completely dry. Repair any cracks before applying the primer
New tarmac over existing tarmac (overlay):Yes, a 25–40mm wearing course overlay can be applied over a sound existing tarmac base, reducing the existing level difference. The existing surface must be stable and free from potholes. A tack coat is applied first
Block paving over existing concrete or tarmac:Possible but not ideal — the existing surface must be absolutely level (no more than ±10mm variation) and the increased finished height must be acceptable at the threshold and edges. Standard approach is to reduce the sand bed depth to compensate
New concrete over existing concrete:Not generally recommended — bonding between old and new concrete is unreliable and differential movement causes cracking. Break out and replace instead
Never overlay a surface that is structurally failingheaving, cracked, or subsiding. The failure will reflect through the new surface within months

In most cases, noa standard domestic driveway does not require building regulations approval in England and Wales
Exception — drainage connection to public sewer:If you are making a new connection to the public surface water sewer (not soakaway or infiltration), you may need to notify the sewerage undertaker and in some cases obtain building regulations approval for the drainage work under Part H of the Building Regulations
Exception — structural alterations:If the driveway installation involves significant alterations to the building structure (e.g. removing a section of external wall to create a new garage opening, or underpinning a boundary wall), the structural work will require building regulations approval
Exception — commercial premises:Building regulations approval may be required for driveway works at commercial, industrial, or mixed-use premises — check with your local authority building control
Even where building regulations approval is not required, planning permission rules still apply separately — the two are independent processes
