Our cookie policy

What are cookies and why do we use them?

Cookies are small text files placed on your device when you visit a website or application. Your web browser (such as Google Chrome, Internet Explorer or Mozilla Firefox) then sends these cookies back to the website on each subsequent visit so that they can remember things like preferences.

Cookies are very useful and do lots of different jobs. For example, they enable you to move between our web pages efficiently, they remember your preferences when you visit us again and generally improve your experience when browsing with us. They can also help to ensure that adverts you see online are more relevant to you and your interests.

Cookies last for different lengths of time depending on the job they do. There are session cookies and persistent cookies:

  • Session cookies only last for your online session and disappear from your device when you close your browser
  • Persistent cookies stay on your device after the browser has been closed and last for the period of time specified in the cookie

Your choices

We will only read or write cookies for the preference level you set when you first visit our website.

Please note that cookies set before you changed your settings will still be on your computer. You can remove them using your browser settings.

Our free online tool can help you manage the cookies we use on bt.com. To use it, your web browser needs to support JavaScript – if it doesn't you can still find out about the cookies we use here, but you'll need to manage them through your web browser settings.

We also use a cookie to remember your cookie preferences. This means:

  • If you delete all your cookies you will have to update your preferences with us again – we’ll ask you when you next visit our website
  • If you use a different device, computer profile or browser you will have to tell us your preferences again

Managing cookies

There are ways you can control and manage cookies on your device. Please remember that any settings you change will not just affect the cookies we use. These changes will apply to all websites you visit (unless you choose to block cookies from particular sites).

Managing cookies in your browser

Most browsers will allow you to choose the level of privacy settings you want. You can block all cookies, or accept all cookies or pick a setting somewhere in between. This range lets you control your cookie settings, so you can:

Deleting cookies means that any preference settings you have made on a website will be lost. If you’ve set your preferences to opt out of cookies, this setting will be lost too, as that information is stored in a cookie. Blocking all cookies means functionality on our websites will be lost, as described above. We don’t recommend turning all cookies off when using our websites.

If you want to reduce your cookie settings at any time – for example, if you accept all cookies, but later decide you don’t want a certain type of cookie – you’ll need to use your browser settings to remove any third party cookies dropped on your previous visit.
