About accessibility and the measures we've taken

Web accessibility is the practice of making website content available to all users, particularly those with disabilities, including visual, auditory, physical, speech, cognitive, and neurological disabilities. It includes making a website as accessible as possible regardless of browsing technology, such as for people with text-only web browsers and old browser versions.

We are committed to making this website accessible to as many people as possible. To this end this website has been developed to meet all AA accessibility checkpoints, wherever possible, as defined by the World Wide Web Consortium's (W3C) Web Accessibility Initiative (WAI).

Accessibility measures

Some of the measures we have taken to ensure our site is accessible include:

  • Our website uses relative font sizes to enable users to change the size of text on the page
  • We use alternative text for images on our website
  • All our web pages use valid XHTML and CSS (Cascading Style Sheets)
  • We conduct regular validation checks to ensure the HTML code of our web pages is valid
  • We run regular spot checks of our pages against accessibility testing tools
  • We perform periodic audits of our site against WAI Priority 1 and 2 checkpoints and fix any errors

Compliance with web accessibility is an ongoing process which we are regularly working to improve. Some of our content is currently spread across several different websites due to the historic nature in which our project websites have been hosted on different platforms. In view of this, there may be some content which does not yet meet all the guidelines. It is also recognised that it is sometimes difficult to achieve maximum web accessibility in the provision of a modern, dynamic website that, for example, uses embedded media players or widgets. If you experience problems accessing any of the information on our site, please contact our Web Team at and we will try our best to fix the problem or provide the information in an alternative format.
