To make our sites work properly, we sometimes place small data files called cookies on your device. Most websites do this. Cookies do not harm your system.

No cookie-related information is ever used to identify you personally. These cookies are not used for any purpose other than those described here.

What are cookies?
A cookie is a small text file that a website saves on your computer or mobile device when you visit a website. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.

For residents of the UK, the EU, California, or other jurisdictions, we are required to obtain your consent for all non-essential cookies used on our websites.

You can block cookies at any time by activating the setting on your browser that allows you to refuse the placing of all or some cookies. However, if you use your browser settings to block essential cookies you may not be able to access all or parts of our sites.

How do we use cookies?
We use cookies to track how visitors use our websites. Some cookies are essential for the websites or certain functionalities to work, with some intended to enhance the performance of the websites.

​Pages on our websites use cookies to remember:

  • a user’s actions, and to identify users who have previously visited
  • your display preferences, such as contrast, colour settings or font size
  • if you have already replied to a survey pop-up that asks you if the content was helpful or not (so you won't be asked again)
  • if you have agreed (or not) to our use of cookies

Also, some videos we may embed in our website pages use a cookie to anonymously gather statistics on how you got here and what videos you visited.

They usually store an anonymous session ID allowing you to browse a website without having to log in to each page but they do not collect any personal data from your computer; or
