Cookie policy

What cookies are

Cookies are small text files stored on your device when you visit a website. They let a site remember your actions and preferences, recognise you across visits, and — where you've agreed — help us understand how the site is used.

Categories we use

Necessary

Required for the site and cookie-consent tool itself to function. These cannot be switched off, and don't require consent under applicable law because the site cannot operate properly without them.

Analytics

Help us understand which pages are useful and where visitors drop off, so we can improve navigation and content. Only set once you opt in.

Marketing

Used to measure the effectiveness of our campaigns and, where relevant, to show more relevant content. Only set once you opt in.

Managing your choice

You can change your cookie preferences at any time using the "Cookie preferences" link in the site footer, which reopens the consent settings shown on your first visit. You can also block or delete cookies through your browser settings — note that doing so may affect how parts of the site work.
