Cookie policy

When we provide information, we want to make the process easy and reliable. Where we do this on the internet, it sometimes involves placing small amounts of information on your device, for example your computer or mobile phone. These include small files known as cookies. They cannot be used to identify you personally.

These pieces of information are used to: enable us to recognise your device so you don’t have to give the same information several times during one task; and measure how many people are accessing information, so that there is enough capacity to ensure that this can be done quickly and easily.

Cookies in the analytics category are opted into by the user through the cookies banner when you first come to the site. Cookies in the essential category are required by the site to run correctly and therefore always need to be on.
