We believe that this website meets or exceeds the requirements of the level A criteria of the World Wide Web Consortium Web Accessibility Initiative (WCAG WAI) 2.0 guidelines.

Accessibility features

Keyboard access

We have provided ‘Skip to main content’ links to allow direct access past the navigation menu to the page’s main content.

Text size

You can vary the text size by using your browser’s text resize option; this is usually located amongst the menu options under ‘View’.

Heading elements

HTML heading elements have been used to represent page structure, supporting assistive technologies that allow page navigation from heading to heading.

Link text

All hyperlinks should make sense when read out of context, and hyperlinks are clearly presented in a different text style from normal body text.

JavaScript independence

Where JavaScript or other scripts are used for navigation or functionality, an alternative mechanism has been put in place in case your browser does not support these scripts or you have chosen to disable them.

Colour contrast

We have checked text and background colour combinations to ensure that the contrast is sufficient for users with visual impairments. We have also ensured that information is not referenced by colour alone.

Style sheets 

We have used cascading style sheets (CSS) to control the presentation of pages and have ensured that content itself is properly structured using HTML. If CSS is not supported, or is turned off, information on the site can still be accessed and read.

Questions and feedback

If you have any difficulty in accessing any information on this website or if you have any feedback for us, we would like to hear from you. Please contact us.
