Cookies on all of our sites
We use Google Analytics and Hotjar Heatmaps across our suite of websites and further information is set out in the ‘Cookies on all of our sites’ section of this page.
Cookie
PHP session
Purpose
Essential
What does this cookie do?
When you visit the Elexon Portal (whether you are logged in or not), calculations are carried out to to work out what you are/are not allowed to access in your current state. To preserve performance of the site, rather than carrying out all these calculations every time you load a page, we cache them in a web server “session”, and store a cookie on your computer with the session ID. If we didn’t do this, the performance of the site would not be able to be maintained, so we class this as essential to the site’s operation. This cookie does not contain any personally identifiable information.
Cookie
Portal cookie preference
Purpose
If you choose to opt out of any Elexon Portal cookies, a cookie will be stored on your computer to signify this. While it may seem counter-intuitive to store a cookie to specify that you don’t want any cookies, this is the only way that we can know about your preference when you return to the site.
Cookie
Portal login
Purpose
Essential
What does this cookie do?
When you choose to log in to the Elexon Portal, additional set of login cookie information is stored on your computer to tell the back-end security systems who you are and to validate that you are logged in. The reason this is done with a separate login cookie (rather than using the session cookie for example) is because each of your page views has to be verified against our back-end single sign on architecture, and because your session cookie is destroyed when you close your browser (so we wouldn’t be able to remember you when you come back later).
Cookie
Javascript – tree state
Purpose
Functional
What does this cookie do?
When you expand or contract the content tree in the sidebar, javascript is used to store these tree expansion states in a cookie so that the tree remains in your chosen state as you navigate from page to page. If you opt out, the tree will revert to its default state every time you load a new page, which we feel may affect your user experience, so we recommend that you allow this cookie type. This cookie does not contain any personally identifiable information.

This is one of the four main cookies set by the Google Analytics service which enables website owners to track visitor behaviour and measure site performance.

In this older version this was used in combination with the __utmb cookie to identify new sessions/visits for returning visitors. When used by Google Analytics this is always a Session cookie which is destroyed when the user closes their browser. Where it is seen as a Persistent cookie it is therefore likely to be a different technology setting the cookie.
