Cookies are small text files placed on your device when you visit a website. They're widely used to make websites work, work more efficiently, and to provide reporting information to site owners.
This site uses cookies and similar technologies set by Google, via Google Tag Manager, for the following purposes:
We do not use cookies for purposes unrelated to understanding site performance and advertising effectiveness — we don't sell cookie data to third parties or use it to build advertising profiles outside of Google's own advertising products.
Our postcode coverage checker sends the postcode you enter to postcodes.io, a public UK postcode lookup service, to determine the general location. This request doesn't set a cookie and we don't store the postcodes you check.
Our interactive coverage map uses map tiles from CARTO and OpenStreetMap, which may load resources from their servers when you view the map.
Most web browsers let you control cookies through their settings, including blocking or deleting them. Blocking all cookies may affect how parts of this site work, though our core content and enquiry form will still function normally. You can find instructions for managing cookies in your specific browser's help documentation.
You can also opt out of Google Analytics tracking across all websites using Google's official browser add-on, available at tools.google.com/dlpage/gaoptout.
We may update this cookie policy from time to time, for example if we start using a new tool or service. The date at the top of this page shows when it was last updated.
