Cookie policy

To make this site simpler, we sometimes place small data files on your computer. These are known as cookies. Most big websites do this too.

They improve things by:

  • remembering settings, so you don’t have to keep re-entering them whenever you visit a new page
  • remembering information you’ve given so you don’t need to keep entering it
  • measuring how you use the website so we can make sure it meets your needs

Our cookies aren’t used to identify you personally. They’re just here to make the site work better for you. Indeed, you can manage and/or delete these small files as you wish.

To learn more about how advertisers use cookies and how you can control these please visit Your Online Choices. To learn more about your rights to online privacy, please visit Data Protection Act 1998 and The Information Commissioner’s Office.
