Every cookie we set, who sets it, and how to turn things off.

These are required for the site to work as you'd expect. They cannot be turned off, because turning them off would break the basic behaviour you're relying on. None of them are used for tracking.

Set only after you've turned the Analytics category on. They help us see which pages are useful and where people get stuck — without them we'd be guessing.

We use two services. Google Analytics 4 gives us page views, traffic sources, and the events we instrument (signup attempts, postcode submissions, and so on). We have IP anonymisation on and Google Signals off, so Google does not use this data to build advertising audiences. Microsoft Clarity gives us session replay and heatmaps — useful for spotting layout problems and confusing copy. Microsoft's terms allow them to use aggregated Clarity data to improve their products; disclosing that here is part of using the service.

Some of the cookies below are first-party (set on heatpass.co.uk) and some are third-party (set by Microsoft on their own domains as part of how Clarity works). We can delete first-party cookies for you when you withdraw consent; the third-party ones live on Microsoft domains and have to expire on their normal schedule. We disclose them all so you know what's happening.

Set only after you've turned the Marketing category on. We use Google Ads conversion measurement to see which adverts actually bring people who go on to check their home or ask to be connected with an installer. That lets us spend the budget on adverts that work instead of ones that don't.

Through Google's Consent Mode the Google Ads tag sits on the page in the same anonymous, cookieless state as Analytics, and it only sets the cookies below once you turn Marketing on. Leave Marketing off and we store no Google Ads cookie on your device. We don't show adverts on this site, and we don't sell your data. This is measurement only, so we can see which adverts are worth paying for.

The two cookies differ in where they live. _gcl_au is first-party, set on heatpass.co.uk. IDE is set by Google on its own domain, so like our third-party analytics cookies it expires on its own schedule rather than one we control. If you turn Marketing back off, we delete the first-party _gcl_au cookie straight away and signal Google to stop using both for advertising. If you're signed in to a Google account, Google may also keep its own account cookies that sit outside what this site sets.

Open the cookie banner again with the button below, or use the "Cookie settings" link in the footer of any page. Changing your mind is one click — analytics cookies are deleted from this device on the spot if you turn the category off mid-session, and no further requests go to Google or Microsoft until you turn it back on.

If you want to delete cookies that have already been set, your browser also lets you do that directly. Most browsers expose this in Settings under "Privacy" or "Site data" — you can clear cookies for heatpass.co.uk specifically, or for everything.
