Accessibility statement

Our approach

This website aims to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. In practical terms, the site is built so that you can:

• navigate every page using only a keyboard
• zoom to 200 per cent without text spilling off the screen
• read all text at contrast levels that meet WCAG AA
• use a screen reader — pages use semantic headings, landmarks, labelled forms and descriptive link text
• browse without cookies, pop-ups or content that flashes or auto-plays

How we test

Pages are checked against WCAG criteria during development, including keyboard navigation, heading structure, colour contrast and behaviour at mobile screen sizes. Interactive elements — such as the detection-window explorers in our information hub — are built to work with keyboard and assistive technologies, and information conveyed by colour is always available as text as well.

Known limitations

Some documents offered for download, such as controlled PDF documents, may not yet be fully accessible to screen readers. If you need the content of any document in another format, contact us and we will provide it.

If something does not work for you

If you find a page you cannot use, or you need information from this site in a different format — large print, plain text or a document read over the phone — tell us and we will sort it:

• email info@nivha.net
• phone 02890 737942

Please describe the problem and the page it appears on. We aim to respond within five working days, and accessibility problems are treated as defects to be fixed, not feedback to be filed.

Attending an appointment

Accessibility matters offline too. If you or a client have access requirements for a sample collection appointment — step-free access, extra time, an interpreter or anything else — let us know when booking and we will make the arrangements.
