Updated: 12 September 2026

What are cookies?

Cookies are pieces of data that sites and services you use or visit can set on your browser or device and they can typically be read on future visits to learn more about the user and to personalize an experience, including the ads that are displayed to the User. “Cookies” is also a term that may be used to refer to a range of technologies that help an operator identify users and devices, which in turn can help personalize an experience, prevent fraud, store preferences, and speed up delivery of content.

For more information on how we process your personal information, please see our Privacy Policy.

What types of cookies and other technologies do we use?

As described below we employ a number of technologies to operate the website.

Generally, our cookies fall into the following categories listed below with some examples of the uses for each category:

Strictly Necessary cookies: These cookies are necessary for the website to function and cannot be switched off in our systems. They are often used for security purposes or are set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work.

Functionality cookies: These cookies enable the website to provide enhanced functionality and personalisation. They may be set by us or by third party providers whose services we have added to our pages. If you do not allow these cookies then some or all of these services may not function properly.

Below is a complete list of what we store and why.
