Accessibility statement
Last updated 24 September 2026
Our aim
We want everyone to be able to use this website. It is built to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.
What we have done
- Pages use headings, landmarks, lists and tables so screen readers can navigate them.
- Everything can be reached and used with a keyboard, with a visible focus outline.
- Text colours were chosen to meet contrast requirements, and the layout adapts to small screens and to text enlarged to 200%.
- Photos have text descriptions. Diagrams have a written description, and their content is explained in the text around them.
- The only animation is the listening survey plan, which walks the microphone along the pipe once and shows its final state straight away if your device is set to reduce motion. It can be moved with the keyboard, and each step is announced in text.
- The survey plan’s sound only plays when you press its button, and the same button stops it.
- Questions and answers use standard expandable sections that work with assistive technology.
How we checked
On 24 September 2026 the site was checked at desktop and mobile sizes, with keyboard-only navigation and automated structure and contrast checks. It has not yet been tested by users of assistive technology.
Known limitations
- Reviews link to Trustpilot, which we do not control.
- Some case study photos show instrument screens whose readings are described in the caption and text rather than in full.
