What cookies we use and how

We sometimes place small data files on your computer. These are known as cookies and most websites do this.

They improve things by:

  • remembering who you are after you login to the site
  • prefill some of the online forms with information you already gave to us so you don’t need to keep entering it
  • measuring how you use the website so we can make sure it meets your needs.

Apart from the ones related to the login process our cookies aren’t used to identify you personally. They’re just here to make the site work better for you. Indeed, you can manage and/or delete these small files as you wish.

To learn more about cookies and how to manage them visit AboutCookies.org.

Online forms

When you transact with the council through one of our online forms we store a cookie on your computer containing information on what type of form is launched.
