Privacy policy

This policy explains how Compare Window Prices (“we”, “us”) collects and uses your personal data when you request a window price comparison through this website. We are the data controller for the information you submit here.

What we collect

When you complete our comparison form we collect the details you enter:

We also automatically collect marketing attribution data so we understand how you found us. This includes the campaign source and medium, search or ad terms, advertising click identifiers (for example Google and Meta click ids), the landing page you arrived on, your browser user-agent and your IP address.

How we use your data

We use your details to match you with vetted local installers and to arrange your window price comparison. By submitting the form you agree that we, or a matched installer, may contact you by telephone about your enquiry. Any contact will be directly related to the application you made — that is, your request to compare window prices — and not used for unrelated marketing.

Qualified enquiries are passed to a single matched, accredited installer covering your area so they can provide your quote. Marketing attribution data is used only to measure and improve our advertising.

Lawful basis

We process your contact details on the basis of your consent, given when you submit the form, and our legitimate interest in responding to the request you made. You can withdraw consent at any time using the contact details below.

How long we keep it

We retain enquiry data for up to 24 months from your submission, after which it is deleted or anonymised, unless we are required to keep it longer to meet a legal or regulatory obligation.

Who we share it with

We share your enquiry with the matched installer(s) who will provide your quote, and with the technology providers that host this site and process form submissions on our behalf under appropriate data-protection terms. We do not sell your personal data.

Your rights

Under UK data protection law you have the right to access, correct, delete or restrict the use of your personal data, to object to processing, and to data portability. You also have the right to complain to the Information Commissioner’s Office (ICO), the UK regulator for data protection, by searching for ‘ICO’ online.

Cookies

We set first-party cookies to remember marketing attribution. See our cookie policy for the full detail.

To ask about your data or exercise any of your rights, get in touch using the contact details on our website, or reply to any message we send you. We will respond within one month.
