What we provide

  • Every page works with a keyboard alone, including the menus and the search.
  • Text can be resized to 200 percent without loss of content.
  • Colour contrast meets the AA standard and colour is never the only way information is shown.
  • All animation is switched off when your device asks for reduced motion.
  • Images carry written descriptions and pages use clear headings and landmarks.

Known limitations

Some older documents in the downloads library were produced before this statement and may not be fully accessible. Ask us for an accessible copy and we will provide one.
