About cookies

We use cookies to improve services for you, such as:

  • Enabling a service to recognise your device so you don't have to give the same information several times during a task
  • Recognising that you may already have given a username and password, so you don't need to do it for every web page requesting those details
  • Measuring how many people are using services, to ensure they have enough capacity to be fast and can be made easier to use
