We hope that all users have easy access to information on our website. If you have any problems accessing any content on this site for whatever reason, then please contact us so we can put it right.

Standards compliance

  • All pages comply with all priority 1 and 2 guidelines of the W3 Web Content Accessibility Guidelines.
  • All pages where possible validate as Valid HTML5.
  • All pages use structured semantic markup. For example H1 tags are used for page titles, H2 tags for sub-title headers and H3 for sub-section headers. JAWS users can skip to sub-sections using ALT+INSERT+3.

Navigational aids

  • All pages on this site include a consistent set of navigation links.
  • All pages on this site include a search box.


  • Wherever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
  • There are no “javascript:” pseudo-links. All links can be followed in any browser, even if scripting is turned off.
  • There are no links that open new windows without warning.


  • All content images used on this site include descriptive ALT attributes. Purely decorative graphics include empty ALT attributes.

Visual design

  • This site uses cascading style sheets for visual layout.
  • This site has been designed so that you can increase the font size using the buttons provided beneath the main navigation menu. The site is also compatible with IE7’s zoom feature (CTRL + / CTRL -).
  • If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
  • Alternatives to all javascript functions have been provided if your browser or browsing device does not support javascript.
