How cookies are used on this site

We want our website to be easy to use, useful and reliable. Achieving this sometimes involves placing small amounts of information on your device, for example your computer or mobile phone. This information may include small files known as “cookies”. We do not use these to identify you personally, or to hold any personal data.

These pieces of information are used to improve services for you through, for example:

  • enabling a service to recognise your device so you don’t have to give the same information several times during one task
  • recognising that you may already have provided a username and password so that you don’t need to keep repeating these for every web page requested
  • measuring how many people are using services so they can be improved and make sure there is enough capacity to ensure they are fast

You can easily manage these small files yourself if you know how.

Purpose: To remember your preference on the use of cookies on this site

Cookies for measuring use of services

By understanding how people use our services we can improve the information and service provided. Like many websites we use Google Analytics to do this. Below are the cookies used by Google Analytics

Name: __utma
Purpose: This cookie is typically written to the browser upon the first visit to your site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to your site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure.
Expiration: 2 years from set/update

Name: __utmb
Purpose: This cookie is used to establish and continue a user session with your site. When a user views a page on your site, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on your site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. This cookie expires when a user pauses on a page on your site for longer than 30 minutes. You can modify the default length of a user session with the _setSessionCookieTimeout() method.
Expiration: 30 minutes from set/update

Name: __utmc
Purpose: Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user. For backwards compatibility purposes with sites still using the urchin.js tracking code, this cookie will continue to be written and will expire when the user exits the browser. However, if you are debugging your site tracking and you use the ga.js tracking code, you should not interpret the existence of this cookie in relation to a new or expired session.
Expiration: End of session

Name: __utmz
Purpose: This cookie stores the type of referral used by the visitor to reach your site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation within your own site. The cookie is updated with each page view to your site
Expiration: 6 months from set/update
