What are cookies?
Cookies are very small text files placed on your computer by a web server when you visit the site. They′re used to store data about you and your preferences so that a web server doesn′t have to repeatedly request this information, potentially slowing download time.
Why do we use cookies?
We use cookies to improve your experience on our website and to enhance its speed. We also use cookies to compile anonymous, aggregated statistics that allow us to understand how people use our website and to help us improve its structure and content.
How do we use cookies?
Our websites use different types of cookies:

- Permanent cookies: they remain in operation, even when you have closed the browser. They remember your login details and password so you don′t have to type them in every time you use the site. They stay on your device until they expire or you delete them.
- Third-party cookies: they are used to track and measure usage of our website so that we can continue to produce engaging content. These cookies may track things such as how long you spend on the site or pages you visit which helps us to understand how we can improve the site for you.
- Strictly necessary cookies: they are essential to navigate around our website and use its features (remember items in a shopping basket, provide essential security measures, quick loading and distribution of content).
- Performance cookies: they collect anonymous data for statistical purposes on how visitors use a website, they don′t contain personal information, and are used to improve our user experience on our website (visits to the Website, including numbers of visitors and visits, length of time spent on the site, type of technology, pages clicked on or where visitors have come from.)
- Functionality cookies: they allow users to customise how our website looks for them. These cookies remember if you have been to the site before so that messages intended for first-time users are not displayed to you.
