Cookies are small bits of information that are stored on your computer by websites. These are typically used to remember preferences, the contents of an online "shopping basket" or to track your viewing history to target advertising more effectively.

Essential cookies

The secure part of our website will always need a cookie in order to maintain the security. This cookie only lasts as long as your current session and is not saved on your computer's hard disk. This cookie cannot be made optional without compromising your security.

Performance cookies

Anonymous information is collated and reported using Google Analytics. This prevents us from seeing any individual records and does not collect information that directly identifies you. We can only see summary and trend information, which helps us to understand which pages and topics are most useful to users.
