Accessibility

Accessible, and honest about the gaps.

We want everyone to be able to use this website. This page says what we aimed for, how it was checked and where it falls short.

The standard we aim for

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.

What has been checked

  • Automated testing. Every page was checked with the axe-core accessibility engine, using its WCAG 2.0, 2.1 and 2.2 level A and AA rules, in Microsoft Edge at desktop and mobile widths. No violations remained at the time of testing.
  • Keyboard. The first Tab stop on each page is a visible “Skip to content” link. Interactive elements show a visible focus ring. The mobile menu opens with the keyboard.
  • Reflow. Pages were checked at 320 pixels wide and do not scroll sideways, apart from wide tables, which scroll inside a labelled region that can be reached by keyboard.
  • Motion. If your device asks for reduced motion, the animated lettering and the background video on the home page are switched off.
  • Structure. Each page has one main heading and a sensible heading order, descriptive link text, text alternatives for meaningful images and a language declaration.
  • Colour contrast is covered by the automated rules above.

What has not been checked yet

Automated tools find only part of the problems people meet. These have not yet been done:

  • Testing with screen readers such as NVDA, JAWS or VoiceOver.
  • Manual testing with browser zoom and text-spacing changes beyond the 320-pixel check.
  • Testing with voice-control software.
  • Testing with disabled users, and an independent accessibility audit.

Known limitations

  • The Knowledge Hub search uses a third-party component, which had only the automated checks above.
  • The calculators update their results as you type. Results are announced politely to screen readers, but this has not been tested with them.
  • Video used on the home page is decorative and has no audio.
