Accessibility

We are committed to making this website accessible for all our users. If you have any problems using the site, please let us know using the Contact page.

We have developed the site according to the conventions of the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI), using the guidance provided by the RNIB's Web Access Centre.

Colour Contrast

The colours used in this site have been analysed using the Contrast Analyser tool provided by the Web Accessibility Tools Consortium to confirm that they should provide clear contrast for all users.

Skip to Content links

'Skip to Content' links are provided at the start of each page. These allow users of reader software, and those accessing the site using keyboard only to skip the navigation menus at the top of each page and go directly to the page content. 'Skip to Content' links will become visible when you first press the Tab key on a page.

Please note that there is a problem with using the 'Skip to Content' links in the Google Chrome browser when using keyboard tabbing. This causes the tab focus to remain within the navigation menu after the link is activated. For this reason, you may want to consider using a browser other than Chrome if you are using keyboard only to access this site.

Javascript

Wherever Javascript is used in this site, equivalent functionality is provided automatically for users whose browsers do not have Javascript enabled.
