We use cookies on our website which, amongst other things, help us to improve your experience of our website and to ensure that it performs as you expect it to. Cookies are text files containing small amounts of information, which are downloaded to your computer or mobile device by websites that you visit. They can improve your experience of using a website, for example, by remembering your preference settings and tracking your use of a website so that it can be improved to meet your needs.

To find out more about cookies, including how to see what cookies have been set, visit the following websites:



Unless the cookie is a strictly necessary cookie, you can withdraw your consent to our cookies at any time even if you have previously consented. Although, please do remember that if you do not consent to our functionality cookies, parts of our website will not work.

The table below explains what cookies we use on our website, why we use them and whether they are a “strictly necessary” cookie, or another type of cookie e.g. a "functionality" or "performance" cookie. We also state in the table whether a cookie is a "persistent" or "session" cookie. The difference is that:

  • Persistent cookies remain on your device between browsing sessions. They are activated each time you visit the website that created that particular cookie. For example, where a "persistent cookie" is used on a website to remember your log-in details, you will not need to enter those details each time you visit that website.
  • Session cookies allow website operators to link the actions of a user during a browser session. A browser session starts when you open the browser window and finishes when you close the browser window. Session cookies are created temporarily. Once you close the browser, all session cookies are deleted.

The cookies listed below are those set by our own website when you visit.
