Information we collect
When you complete our enquiry form we collect the details you enter:
- Your first name and last name
- Your email address
- Your phone number
- Your postcode
- Your answer to whether you own your home
We also automatically collect marketing attribution data so we understand how you found us. This includes the campaign source, medium and search term (for example UTM values), advertising click identifiers passed by platforms such as Google and Meta, the first page you landed on, your browser type (user agent) and your IP address.
How we use your information
- To match you with suitable double glazing installers covering your area.
- To pass your enquiry to those installers so they can prepare a quote.
- To contact you about your enquiry and to improve our service.
- To keep records and prevent duplicate or fraudulent submissions.
How we will contact you
We (or the installer we match you with) will contact you by phone, and this contact is directly related to the application you made through this website. We may also reach you by email or text about the same enquiry. We do not use your details for unrelated marketing.
Who we share it with
Qualified enquiries are passed to one or more matched double glazing installers — which may include our installation partner, Help 2 Buy Windows — so they can contact you about your request. We only share what is needed for them to quote, and only in connection with the enquiry you made. We do not sell your data for unrelated purposes.
Legal basis
We rely on your consent (given when you submit the form and agree to be contacted about your enquiry) and on our legitimate interest in operating a quote-comparison service. You can withdraw consent at any time using the contact details below.
How long we keep it
We keep your enquiry data for up to 24 months from your last contact with us, after which it is securely deleted or anonymised, unless we are required to keep it longer to meet a legal or regulatory obligation.
Your rights
Under UK data protection law you have the right to access, correct, delete or restrict the processing of your personal data, to object to processing, to data portability, and to withdraw consent. You also have the right to complain to the Information Commissioner’s Office (ICO) at ico.org.uk.
Cookies
We set first-party cookies to remember your marketing attribution. See our cookie policy for the full list and how to manage them.
Contact us about your data
To ask about the personal data we hold, to exercise any of your rights, or to withdraw consent, please contact our data protection team by replying to any message we send you about your enquiry, or through the contact options provided on this website. We will respond within one month.
