How we use cookies

Our website uses cookies in order to personalise our service to you and improve your experience of our website. If you do not want cookies to be used, you can set your internet browser to deny them.

What are cookies?

Cookies are small pieces of information that are placed on your device (for example, computer or mobile phone). They cannot be used to identify you personally. They are used to improve your experience of our website by, for example:

  • enabling our website to recognise your device so you don't have to give the same information several times during one task
  • recognising where you have already given a username and password so you don't need to do it for every web page requested, or for each time you return to our site
  • recording items you have added to your shopping basket and your progress through online transactions
  • measuring how people are using our website, so we can make it easier to navigate and ensure there's enough capacity to display page content quickly

How do we use cookies?

We use a combination of session cookies (which last only for the duration of your visit and are deleted when you close your browser) and persistent cookies (which last beyond your session and remain on your computer until you choose to remove them). We do not use any third party cookies for advertising or marketing purposes.
