Accessibility
This site aims to meet WCAG 2.2 Level AA. This page says what that means in practice, what we actually test, and what to do if something here does not work for you.
Last updated 17 August 2026
What we have built for
- Screen readers. Every page has one main heading and a proper heading structure, images carry descriptions written for what they actually show, and form fields are joined to their labels.
- Keyboard only. Everything that can be clicked can be reached and operated with a keyboard, with a visible focus outline. A “skip to content” link is the first thing you reach on every page.
- Reduced motion. If your device asks for less motion, animations do not play — content appears immediately instead.
- Colour contrast. Text meets the AA contrast ratio in both light and dark themes.
- Zoom and small screens. Pages work down to a 320-pixel-wide screen and when text is enlarged, without content being cut off sideways.
How we check
Automated accessibility testing runs against every public page, in both light and dark themes, at phone and desktop widths — and with reduced motion turned on, which matters more than it sounds: without it, a checker sees only the part of the page that has finished animating and silently skips the rest. That mistake once produced a clean report while 172 real problems existed, so it is now part of how every check runs.
Automated tools cannot catch everything. Keyboard navigation, focus handling in dialogs, and whether an image description is actually true are checked by hand.
Known limitations
Some documents on the documents page are scans of paper certificates. A scan is an image, so screen-reader software cannot read its text. If you need the contents of any of them in an accessible format, ask us and we will send it in one.
Tell us if something blocks you
If any part of this site is difficult or impossible to use, please write to [email protected] with the page address and what happened. We reply within 2–3 working days, and we will give you the information you were after by another route while we fix the page itself.
Target standard: WCAG 2.2 Level AA. This statement describes the site as built and tested; it is not a third-party certification.
