Terms of Use

Last updated:

These terms apply to your use of the House Extension Cost Calculator website at houseextensioncostcalculator.co.uk. By using the site, you accept these terms. If you do not accept them, please do not use the site.

Our service

We provide a free house extension cost calculator and a service that matches your enquiry with relevant tradespeople and partners who may quote for your project. We are not a building company, we do not carry out building work, and we are not a party to any contract you enter into with a tradesperson.

Estimates are a guide, not a quote

The figures produced by the calculator are budgeting estimates based on typical UK market rates. They are not quotes and do not guarantee the price of any work. Actual costs depend on your site, your builder and your chosen specification. You should always obtain written quotes before committing to a project, and confirm official figures such as planning and building control fees on GOV.UK and with your local council.

Third party tradespeople

Any tradespeople or partners we introduce are independent businesses. We do not control their work, pricing or conduct, and we are not responsible for the services they provide or any contract you make with them. You are responsible for carrying out your own checks before engaging any tradesperson.

Acceptable use

You agree to use the site only for lawful purposes, to provide accurate information, and not to misuse the site, attempt to disrupt it, or use it in any way that could harm us or others.

Intellectual property

The content, design and calculator on this site are owned by us or our licensors and are protected by law. You may view and use the site for your own personal, non commercial use. You may not copy or reuse our content without permission.

Limitation of liability

The site and the calculator are provided on an "as is" basis. To the extent permitted by law, we are not liable for any loss arising from your reliance on the estimates, from your use of the site, or from any dealings with third party tradespeople. Nothing in these terms limits liability that cannot be limited by law.

Links to other sites

Our site may link to third party websites. We are not responsible for their content or their privacy practices.

Governing law

These terms are governed by the laws of England and Wales, and any disputes will be subject to the courts of England and Wales.
