We offer a text only version of our site with options to change foreground and background colours. It provides a faster browsing experience for those using mobile devices or on slow connections. The site can be read whatever size and type of screen you use. The text only version is exactly the same site without the images and layout. It is not a separate site. This guarantees that the information will always be exactly the same no matter how it is viewed. To change to text only, click the ‘text only’ link.
Images and design
All images have ALT tags. Where appropriate, ALT tags provide screen reader users and those with images turned off with a description of the content of the picture.
All videos have Closed Captions available, and a full descriptive text transcript available for download.
