What is a cookie or similar tracking technology?
Cookies are small text files that are stored on your device by websites you visit. They allow the website to recognise your device and certain information about your visit, such as your preferences or settings.
Websites often also use similar tracking technologies, such as pixels and tags. These technologies can store or access information on your device in a similar way to cookies. They help us understand how people use our website and, where consent is given, allow us to deliver and measure advertising through third-party platforms such as Facebook or Google.
For the purpose of this notice, we refer to cookies and similar tracking technologies collectively as ‘cookies’.
Managing your cookies preferences
We use strictly necessary cookies without your consent because they are essential for our website to function properly and to provide the services you request.
We will only use non-essential cookies, such as analytics, performance or advertising cookies, if you provide your consent. Non-essential cookies will not be placed on your device unless and until you have given your consent. When you first visit our website, you will see a banner allowing you to accept, reject or customise your preferences for these cookies. You can change your preferences or withdraw your consent at any time by visiting your cookie settings.

Email tracking
We may also measure the effectiveness of the emails we send. We use our email platform (Dotdigital) to track whether emails are opened and which links are clicked. This is done using similar tracking technology (such as tracking pixels). This helps us understand which content supporters find most engaging and improve future communications.
What types of cookies do we use on our website and why?
We use ‘first party cookies’, which are cookies set by us when you visit our website. These cookies help our website work properly and give you a more personalised experience.

We also use ‘third party cookies’ which are placed by other companies on our behalf, such as social media platforms or our advertising partners. These are cookies that are used to help us advertise content to you on social media, to measure the impact of our advertising campaigns and to understand how people interact with our website.
Cookies can vary in how long they stay active. For example, ‘session’ cookies are temporary and expire when you close your browser, because they are used to recognise what a website user does within a single website visit. Whereas ‘persistent’ cookies remain on your device for longer, because they are used to recognise returning users and their settings.
