We aim to make this site as accessible as we can. To meet this commitment, this website adheres as closely as possible to the Web Accessibility Guidelines, published by the W3C group, and the UK Government’s guidelines in the Disability Discrimination Act (1995).

Web accessibility means enabling people to view a web page the way they wish to view it with the equipment that they have available. In other words, making sure that as many people as possible can use a website, irrespective of physical impairment (such as loss of sight or restricted mobility), cognitive disability (such as dyslexia), or limited English language. It also means ensuring a website works on the broadest possible range of computer hardware and software.

We develop our online content to support a reasonable range of web browsers and operating systems.
