Terms of Use

1. About this website

Material Calculator (materialcalculator.co.uk) provides free online calculation tools to help users estimate material quantities and costs for construction, DIY and landscaping projects in the United Kingdom. The website is operated as a free service and is not affiliated with any material supplier, manufacturer or professional body.

2. Nature of the service — guidance only

All results produced by our calculators are indicative estimates for guidance purposes only. They are not professional advice, structural calculations, or a substitute for the advice of a qualified person.

Material quantities can vary significantly depending on site conditions, ground bearing capacity, substrate type, material supplier specifications, application methods, skill level, and environmental factors. Our tools apply standard UK industry assumptions and published data which may not reflect the specific requirements of your project.

You must not rely solely on the results of any calculator on this website when making purchasing decisions, preparing formal quotes, or commencing any construction or civil engineering work. Always verify quantities with a qualified professional, structural engineer, or your material supplier before ordering or committing to any works.

3. Limitation of liability

To the fullest extent permitted by applicable law, Material Calculator and its operators accept no liability whatsoever for:

• Any financial loss, over-ordering, under-ordering, or wasted expenditure arising from reliance on our calculation results;
• Any loss, damage, injury or cost arising from construction or installation work carried out in reliance on our tools;
• Any inaccuracy, error or omission in the data, algorithms, pricing or output produced by any calculator;
• Any indirect, consequential, special or incidental loss of any kind;
• Interruptions to the service, including downtime, errors or unavailability.

Nothing in these terms limits or excludes liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be lawfully excluded under English law.

4. Pricing accuracy and no warranty

Prices and cost estimates displayed on this website are indicative figures based on publicly available UK market data at the time of publication. They are provided for guidance purposes only and do not constitute a quote, offer, or guarantee of availability.

Material Calculator makes reasonable efforts to keep pricing information current but cannot guarantee that prices shown reflect the current retail prices of any supplier, including affiliate partners. Supplier prices may change without notice.

You should always verify the current price directly on the supplier's website before placing an order. Material Calculator accepts no liability for any loss or damage arising from reliance on pricing information displayed on this website.

5. Affiliate relationships

Some links on this website are affiliate links. When you click an affiliate link and complete a purchase, Material Calculator may receive a commission from the retailer. This commission is paid by the retailer from their own margin and does not affect the price you pay.

Affiliate commission does not influence our calculator logic, quantity recommendations, cost estimates, or the order in which results are displayed. We operate independently of our affiliate partners in all editorial and technical decisions.

All affiliate links are clearly identified with an "Affiliate" label at the point of display. A full list of current affiliate partners, along with commission rates and cookie durations, is available at materialcalculator.co.uk/affiliates.

6. Not a substitute for professional advice

Some calculators on this site touch on areas that are subject to building regulations, planning law, structural requirements or electrical safety standards. In particular:

• The cable size calculator provides guidance under BS 7671 only. All electrical installation work in a dwelling must be designed, installed and certified by a competent person registered under Part P of the Building Regulations;
• Structural calculations (for example, rafter span tables or foundation depths) are indicative only. Any structure that requires structural integrity should be designed by a qualified structural engineer;
• Planning and permitted development guidance is for general information only and does not constitute legal advice. Requirements vary by property, location and local authority.

Material Calculator is not a regulated professional service. Nothing on this website constitutes legal, structural, electrical, financial, or planning advice.

7. Intellectual property

All content on this website — including but not limited to text, code, calculation algorithms, SVG diagrams, design elements, and written guides — is the intellectual property of Material Calculator and is protected by copyright.

You may use the output of our calculators for personal or commercial project planning. You may not copy, reproduce, republish, distribute or create derivative works from the website's code, design or written content without our prior written permission.

8. Acceptable use

You agree not to use this website to:

• Attempt to access, copy, reverse-engineer or scrape our code, data or algorithms by automated means;
• Overload, disrupt, or interfere with the operation of the website or its hosting infrastructure;
• Use the site in any way that is unlawful, harmful or fraudulent.

We reserve the right to block access from any IP address or user agent that appears to be abusing the service.

9. Third-party suppliers

Supplier links on this website — whether affiliate or non-affiliate — direct you to independent third-party websites operated by those suppliers. Material Calculator has no control over, and accepts no responsibility for, the content, pricing, product quality, delivery, or terms of any third-party supplier.

Any purchase you make through a third-party link is a contract between you and that supplier. Material Calculator is not a party to that transaction and accepts no liability arising from it.

10. Privacy

We do not require users to create an account, and we do not store the inputs or results of any calculation. Our use of cookies and any data we collect is governed by our Privacy Policy.

11. Changes to these terms

We may update these Terms of Use at any time. The current version will always be available at this URL. Continued use of the website following any change constitutes acceptance of the revised terms. We recommend checking this page periodically.

12. Governing law

These terms are governed by and construed in accordance with the laws of England and Wales. Any disputes arising in connection with these terms or your use of the website shall be subject to the exclusive jurisdiction of the courts of England and Wales.
