This site, like many others, stores small files (called ‘cookies’) on your computer to collect information about how you use the site.

Consent banner cookie

We use a cookie to remember that you’ve clicked on the ‘I accept’ button on the cookie banner at the bottom of the screen.

Cookie name	What it does	Expires
catAccCookies	Set by the UK cookie consent plugin to record that you accept that the site uses cookies.	1 month

Google Analytics cookies

We track the number of visitors to the site using Google Analytics. However:

• we do not send any personal information about you to Google Analytics
• we anonymise your IP address before it’s sent to the Google Analytics servers, so there’s no way to identify which computer visited the site
• we set the main Google Analytics cookie (_ga) to expire at the end of your browsing session, rather than the default 2 years – this means we do not track whether you’ve visited the site before

Cookie name	What it does	Expires
_ga	Set by Google Analytics to track visitor information.	After your browsing session
_gid	Set by Google Analytics to group your entire browsing session together as the activity of one user.	24 hours
_gat_gtag_[property_id]	Set by Google Analytics to limit the rate that data is sent to its servers.	1 minute
