Cookie policy

This policy explains the cookies and similar technologies Double Glazing Quotes UK uses, why we use them, and how you can control them. It sits alongside our privacy policy.

What cookies are

Cookies are small text files stored on your device when you visit a website. They let a site remember information between pages and visits. We also use your browser’s local storage in the same way for the items described below.

Marketing attribution cookies we set

When you arrive on the site we set first-party wml_* cookies (and matching local storage entries) to record how you found us. These store marketing attribution data — UTM values (source, medium, campaign, term, content), ad platform click identifiers such as gclid, fbc and fbp, and the page you first landed on. They expire after 90 days. This lets us attribute an enquiry to the right campaign if you browse the site, leave and return later.

Cookie	Purpose	Expiry
wml_utm_source, wml_utm_medium, wml_utm_campaign, wml_utm_term, wml_utm_content	Store the marketing source, medium and campaign that referred you	90 days
wml_gclid, wml_fbc, wml_fbp and similar	Store ad platform click identifiers so an enquiry is attributed correctly	90 days
wml_landing_url	Records the first page you arrived on	90 days

Tag manager and analytics cookies

Our pages include a Google Tag Manager container that is currently switched off. If we enable it, it may load analytics or advertising tags (for example Google Analytics or advertising pixels) that set their own cookies — such as _ga and _ga_* for analytics, or _fbp/_fbc for advertising. When that happens, this policy will be updated to list those cookies and their purposes before they are set.

Managing cookies

You can delete or block cookies through your browser settings, and clear your browser’s local storage there too. Blocking our attribution cookies will not stop the quote form working — attribution is best-effort and never required to submit an enquiry.
