Privacy Policy | ConcreteMaths

concretemaths.com/ privacy policy for UK users, covering guide use, contact forms, cookies, analytics, supplier enquiries and your UK GDPR rights in 2026.

Last updated: 20 June 2026.This Privacy Policy explains how concretemaths.com/ handles personal information when you use our concrete guides, UK construction guides, supplier finder pages, quote templates, downloads, contact forms and educational resources. It is written for homeowners, self-builders, tradespeople, contractors, suppliers and website visitors who want clear information before using our resources.

concretemaths.com/ is designed to make concrete planning easier. Many of our resources, such as volume guides, material list creators, concrete grade guides and cost guides, can be used without creating an account. In many cases, the numbers you enter into guides are processed in your browser only. When you choose to contact us, submit a correction, request supplier directory changes, send a project question or interact with optional website features, we may receive personal information from you.

This policy follows the UK data protection principles of lawfulness, fairness and transparency. The Information Commissioner’s Office explains that people have the right to be informed about the collection and use of their personal data, so this page sets out what we collect, why we collect it, how long we keep it, when we share it, and what rights you have. For official guidance, you can read the ICO’s pages on theright to be informedandUK GDPR guidance.

Important:

Use this simple helper to identify the most relevant privacy route. It does not submit your request automatically; it simply tells you what to include when contacting concretemaths.com/. For a formal request, use the contact details on this page and include enough information for us to identify the record you are asking about.

concretemaths.com/provides UK-focused concrete guides, construction estimating resources, concrete grade explanations, material quantity guides, supplier directory pages, regulatory overviews and practical building resources. Our website is intended to help users plan concrete projects more accurately, compare material quantities and understand common UK construction terms.

For privacy purposes, the website operator is the organisation or person responsible for deciding why and how personal information is used. Before publishing this policy, replace the following placeholders with your official details:

Website Owner

[Insert legal business name or trading name responsible for concretemaths.com/.]

Privacy Contact

[Insert privacy email address, such as privacy@concretemaths.com.]

Business Address

[Insert postal address if legally required or appropriate for your business.]

If concretemaths.com/ is operated by a sole trader, limited company, partnership, publisher, web agency or media business, the final published policy should match that real arrangement. Privacy policies should not use a generic company name if users need to know who controls their information.

We aim to collect only the information needed to operate the website, respond to enquiries, improve content quality, prevent misuse and comply with legal obligations. The information collected depends on how you use the site.

Data Category: Identity data; Examples: Name, business name, role, trade type; When It May Be Collected: When you submit a contact form, correction request or supplier update
Data Category: Contact data; Examples: Email address, phone number, postal town, service area; When It May Be Collected: When you ask us to reply, list a supplier or update a business record
Data Category: Project data; Examples: Concrete volume, slab size, project type, postcode region; When It May Be Collected: When included in an enquiry, quote request or saved message
Data Category: Technical data; Examples: IP address, device type, browser, pages visited, timestamps; When It May Be Collected: When you browse the site, subject to cookie and analytics settings
Data Category: Communication data; Examples: Messages, attachments, feedback, complaint details; When It May Be Collected: When you contact us or send support information
Data Category: Marketing preferences; Examples: Email consent, unsubscribe status, topic preferences; When It May Be Collected: Only if newsletter or update features are enabled

We do not intentionally collect special category data such as health, religion, ethnicity, political opinions or biometric information. Please do not send sensitive personal information through a general project enquiry unless it is genuinely necessary. If you accidentally send sensitive information, we may delete it or restrict it unless there is a lawful reason to retain it.

concretemaths.com/ includes guides for ready-mix concrete volume, slab depth, garage base costs, material lists, bags to cubic metres, truck loads, sub-base quantities, concrete grades and related construction planning. These resources are built to provide practical estimates and educational guidance.

Where a guide works entirely in your browser, the numbers you type may be used only to work out the result displayed on the page. For example, if you enter a slab length, width and depth into a concrete volume guide, the resource may work out cubic metres, waste allowance and estimated delivery quantity without sending the measurements to us.

However, guide data may become personal data if you choose to send it to us. For example, if you copy a result into a contact form, attach a project plan, ask us to review quantities, request a supplier quote or email us your postcode and project details, that information becomes part of your enquiry and may be stored with your message.

Guide rule:

Use guides for estimates, not as a substitute for structural engineering or building control approval.
Avoid entering exact private addresses unless a feature specifically requires it.
When asking for help, include approximate project dimensions but remove unnecessary personal details.
If a future account feature is added, this policy should be updated before launch.

We use personal information for practical website and service purposes. We do not sell personal information to advertisers. We do not require users to create an account to read construction guides or use standard guides. We may use information for the following purposes:

Responding

To answer enquiries, correction requests, supplier listing messages, project questions and support requests.

Improving

To improve guides, fix broken links, update outdated prices, clarify technical definitions and improve website performance.

Protecting

To prevent spam, malware, scraping abuse, fraudulent submissions, security incidents and misuse of forms.

Measuring

To understand which guides are useful, subject to cookie law and analytics consent where required.

Directory Accuracy

To verify supplier details, update service areas and remove incorrect or outdated directory entries.

Compliance

To keep records needed for legal, accounting, regulatory, complaints or dispute-resolution purposes.

Under UK GDPR, organisations must have a lawful basis when processing personal information. The ICO explains that processing must align with lawfulness, fairness and transparency principles. The most likely lawful bases for concretemaths.com/ are listed below, but the final published policy should reflect the exact live features on the website.

Purpose: Replying to your enquiry; Likely Lawful Basis: Legitimate interests or contract steps; Plain-English Explanation: We need to use your contact details and message to respond.
Purpose: Sending requested downloads; Likely Lawful Basis: Contract steps or consent; Plain-English Explanation: If you request a checklist or guide, we use your details to deliver it.
Purpose: Newsletter sign-up; Likely Lawful Basis: Consent; Plain-English Explanation: You can unsubscribe at any time if email updates are enabled.
Purpose: Security logs; Likely Lawful Basis: Legitimate interests; Plain-English Explanation: We protect the site from spam, attacks and misuse.
Purpose: Essential cookies; Likely Lawful Basis: Legitimate interests / necessary service; Plain-English Explanation: Some cookies are needed for security, preferences or site function.
Purpose: Analytics cookies; Likely Lawful Basis: Consent unless a valid exception applies; Plain-English Explanation: Analytics resources should follow ICO and PECR rules.
Purpose: Legal complaints; Likely Lawful Basis: Legal obligation / legitimate interests; Plain-English Explanation: We may keep complaint records to meet legal requirements and resolve issues.

When you contact concretemaths.com/, we may collect the information you provide and any technical information needed to process the message. This may include your name, email address, phone number, company name, project location, construction topic, guide result, file attachment, screenshots, correction details and message history.

We use this information to reply, understand your issue, correct website content, investigate supplier directory problems, handle complaints, prevent spam and keep a reasonable record of communications. If you contact us about a concrete project, please remember that we provide general guidance only. We cannot replace a qualified engineer, architect, building control body, contractor or supplier.

If a message relates to a potential legal dispute, safety issue, inaccurate publication, data protection complaint, supplier listing challenge or regulatory matter, we may keep it for longer than an ordinary enquiry. This is to protect legal rights, maintain evidence and demonstrate how the issue was handled.

concretemaths.com/ may publish or process information about UK concrete, aggregate, cement, screed, reinforcement, groundwork, plant hire, building material and construction suppliers. Supplier listings are usually business information rather than private personal data, but some small businesses, sole traders or named contacts may include personal information.

Supplier listing information may include business name, website, public phone number, public email address, branch location, delivery area, service categories, concrete grades supplied, pump availability, opening hours, and public reputation signals. We may obtain this information from the supplier, public websites, business directories, user suggestions or correction requests.

If you own or represent a listed supplier and believe the listing is inaccurate, outdated or should be removed, contact us with the business name, page URL, your relationship to the business and the specific change requested. We may ask for reasonable verification before changing a listing, especially where removal or replacement could affect another business.

Supplier update warning:

Cookies and similar technologies can store information on your device or access information already stored there. The ICO explains that websites must tell people if they set cookies, explain what the cookies do and why, and usually obtain consent unless a cookie is strictly necessary for a service requested by the user. You can read the ICO’s official guidance oncookies and similar technologies.

In 2026, the UK privacy landscape also reflects changes from the Data Use and Access Act. ICO guidance on storage and access technologies was updated to reflect PECR changes and explain exceptions. For live compliance, concretemaths.com/ should use a cookie banner or preference centre that accurately reflects the resources installed on the website.

Cookie Type: Essential cookies; Purpose: Security, load balancing, form protection, cookie choices; Consent Position: May not require consent if strictly necessary
Cookie Type: Preference cookies; Purpose: Remember region, unit choice, guide preferences; Consent Position: Depends on function and necessity
Cookie Type: Analytics cookies; Purpose: Measure visits, popular guides, errors and user journeys; Consent Position: Usually needs consent unless a valid exception applies
Cookie Type: Advertising cookies; Purpose: Personalised ads, retargeting, ad measurement; Consent Position: Consent required before use
Cookie Type: Embedded media cookies; Purpose: Videos, maps, social posts, external widgets; Consent Position: Consent or careful configuration may be required

You can usually control cookies through your browser settings. If concretemaths.com/ uses a cookie banner, you should also be able to change preferences through the cookie settings link or banner mechanism. Blocking some cookies may affect guides, saved preferences, embedded maps, videos or form protection resources.

concretemaths.com/ may use analytics resources to understand which pages are useful, how visitors find guides, which guides need updating and where errors occur. Analytics should be configured to minimise personal data where practical, and non-essential analytics should follow cookie consent rules.

The website may also include affiliate links, sponsored references, comparison links or supplier directory links. If you follow an external supplier, merchant, software, resource or marketplace link, the destination website may collect its own data under its own privacy policy. concretemaths.com/ is not responsible for the privacy practices of third-party websites.

Where affiliate tracking is used, a cookie or tracking parameter may record that you clicked from concretemaths.com/. If a commission is earned, this should not increase your price, but it may help fund the website. Any live affiliate arrangement should be disclosed clearly on the relevant page.

We may share personal information with service providers that help us operate concretemaths.com/. These organisations act as processors or independent controllers depending on the service and contract. The final live policy should list the actual providers used by the website.

Website hosting providers that store website files, databases, logs and backups.
Email delivery providers that handle contact form emails, support replies or newsletters.
Security resources that detect spam, malware, bot traffic and suspicious activity.
Analytics providers that help measure website performance and content usefulness.
Form, CRM or helpdesk resources used to manage enquiries and complaints.
Professional advisers such as accountants, lawyers, insurers or compliance consultants where needed.
Regulators or authorities where required by law or to protect legal rights.

We do not sell personal information. We do not provide private project enquiries to suppliers unless you clearly ask us to do so, a service specifically requires it, or the page clearly explains that your enquiry will be sent to one or more suppliers.

Some website resources, hosting platforms, analytics services, email providers or security vendors may process data outside the United Kingdom. If personal information is transferred internationally, appropriate safeguards should be used where required by UK data protection law. These may include UK-approved transfer mechanisms, adequacy regulations, contracts, risk assessments or vendor-specific safeguards.

Because many website providers operate globally, the final published version of this policy should name the relevant processors and identify whether they process data in the UK, EEA, United States or other regions. If a privacy-conscious analytics resource or UK/EU hosting provider is used, this should also be stated clearly.

We keep personal information only as long as needed for the purpose collected, plus any period needed for legal, accounting, security or dispute purposes. The following table provides practical default retention periods for a construction-information website. Adjust them to match your live operations.

Record Type: General contact enquiry; Typical Retention: Up to 24 months; Reason: To respond and track repeated questions or corrections
Record Type: Supplier listing update; Typical Retention: Up to 36 months; Reason: To verify changes and handle listing disputes
Record Type: Data protection request; Typical Retention: Up to 6 years; Reason: To show how the request was handled
Record Type: Security logs; Typical Retention: 30 days to 12 months; Reason: To protect against attacks, spam and misuse
Record Type: Newsletter consent record; Typical Retention: While subscribed plus audit period; Reason: To prove consent and manage unsubscribe status
Record Type: Legal dispute records; Typical Retention: As required by law; Reason: To protect legal rights and comply with obligations

We use reasonable technical and organisational measures to protect personal information. These may include HTTPS, access controls, secure hosting, software updates, spam filtering, malware scanning, strong passwords, least-privilege access, backup controls and careful handling of attachments.

No website can guarantee absolute security. You should avoid sending highly confidential information, sensitive personal data, bank details, full building plans, passwords or private client information through ordinary contact forms. If a secure transfer route is needed for a specific issue, ask before sending the material.

If we become aware of a personal data breach that creates a risk to individuals, we will assess the situation and take appropriate action. This may include containing the issue, notifying affected users where required, keeping records and reporting to the ICO if the legal threshold is met.

Depending on the circumstances, you may have the right to access personal information, correct inaccurate data, request deletion, restrict processing, object to processing, request data portability, withdraw consent and complain about how your information is handled. The ICO provides official guidance for individuals and organisations on these rights.

Access

Ask whether we hold your personal data and request a copy.

Correction

Ask us to correct inaccurate or incomplete information.

Erasure

Ask us to delete information where there is no overriding reason to keep it.

Restriction

Ask us to pause certain processing while a concern is reviewed.

Objection

Object to processing based on legitimate interests or direct marketing.

Portability

Request portable data where the right applies to digital consent or contract data.

To exercise rights, contact us using the privacy contact details on this page. We may need to verify your identity before acting on a request. We aim to respond within one month, unless the request is complex or multiple requests are made, in which case UK GDPR allows extra time in certain circumstances.

The Data Use and Access Act 2025 introduced changes to UK data protection and privacy law. The ICO has stated that from19 June 2026, organisations must have a process for handling data protection complaints. concretemaths.com/ should therefore provide a clear route for privacy complaints before users go to the ICO.

If you have a complaint about how we handle personal information, please contact us first and include: your name, contact details, the page or form involved, what happened, what right or concern is involved, any reference number, and what outcome you are seeking. We will review the complaint, investigate where needed, and respond within a reasonable period.

If you are not satisfied with our response, you can contact the Information Commissioner’s Office. The ICO is the UK supervisory authority for data protection. Visit theICO websitefor official complaint guidance and contact options.

Publisher note:

concretemaths.com/ is intended for homeowners, tradespeople, students, construction learners, self-builders and professional users interested in concrete and UK construction planning. It is not designed to knowingly collect personal information from children. If you believe a child has provided personal information through the website without appropriate permission, contact us and we will review the issue.

Educational users may read our technical definitions, concrete grade guides and guides, but they should not submit personal information, project addresses or contact details unless supervised by a parent, guardian, teacher or responsible adult.

Our guides may link to official sources such as GOV.UK, HSE, BSI, the ICO, The Concrete Centre, local authorities, building control bodies, supplier websites and standards information providers. These links are provided for convenience, research and user education. Once you follow an external link, the external website controls its own privacy practices.

We recommend reading third-party privacy policies before submitting information to suppliers, quote forms, map resources, embedded videos, social platforms, payment providers or external guides. concretemaths.com/ is not responsible for how external websites handle your personal information.
