They can be used for a range of different purposes, such as customising a website for a particular user, helping a user navigate a website, improving that user’s website experience, and storing that user’s preferences and login information.
Essential and non-essential cookies

Essential cookies: these are cookies that are either:

- strictly necessary to provide an online service (e.g. our website or a service on our website) which you have requested.
Non-essential cookies: these are any cookies that do not fall within the definition of essential cookies, such as cookies used to analyse your behaviour on a website (‘analytical’ cookies) or cookies used to display advertisements to you (‘advertising’ cookies).
Session and persistent cookies
Cookies can be classified as either ‘session’ or ‘persistent’, depending on how long they last after they are placed on your browser.
