How do I manage cookies on your website?

We sometimes place small data files on your computer. These are known as cookies and make your overall experience of our website better.

On your first visit to, you’ll be greeted by an introduction message which will ask if you wish to accept cookies.

Our cookies aren’t used to identify you personally. Instead they’re there to make the site work better for you by:

  • Remembering settings (where provided), so you don’t have to keep re-entering them whenever you visit a new page. For example, we set a cookie when you accept the pop up on our map page. This tells us that you have already accepted the pop up and won’t display it the next time you visit the map from the same computer.
  • Measuring how all users are using the website so we can make sure it meets everyone’s needs – again all information collected is anonymous and can’t be used to identify specific individuals.

You can, if you wish, manage/delete these small files manually. To learn more about what cookies are and how to manage them visit
