Privacy policy

Last updated August 2026

This policy explains what Build Extension Quotes does with the personal information you give us when you use our extension quote tool.

Who we are

Build Extension Quotes operates the website buildextensionquotes.com and is the data controller for the information described in this policy. You can reach us by email at hello@buildextensionquotes.com or by post at Glenbower Court, Hatfield Road, St Albans, AL4 0UH.

What we collect

We only collect what we need to prepare your extension quote and pass it on.

  • Property and project details: extension type, property type, how the property is attached, approximate floor area, number of storeys and any extras you select.
  • Contact details: your name, email address, telephone number and postcode.
  • Technical data: IP address, browser type and basic usage information collected by cookies.

How we use it

We use your project answers to calculate an indicative cost range, we use your email address to send you a copy of that quote together with the next steps, and we pass your enquiry to a suitable local builder so they can offer a free, no-obligation site survey.

We may also contact you about your enquiry, and use anonymised, aggregated data to improve our pricing model and the website.

Lawful basis

We rely on your consent when you tick the box to submit your details, and on our legitimate interests in operating a quotation service and improving our website. You can withdraw consent at any time.

Who we share it with

Your enquiry is shared with the local builder we match you to. We also use trusted service providers for website hosting, database storage and email delivery, who process data only on our instructions.

We never sell your personal information.

How long we keep it

Enquiry records are kept for up to 24 months so we can answer questions about a quote, unless you ask us to delete them sooner.

Your rights

You have the right to access, correct, delete or restrict the processing of your personal data, to object to processing, and to receive a copy of your data. Email us and we will respond within one month.

If you are unhappy with how we handle your data you can complain to the Information Commissioner's Office (ico.org.uk).

Security

The website is served over HTTPS, enquiry data is stored in an access-controlled database and only authorised staff and the matched builder can see your details.
