Accessibility statement

What we have aimed for

The site is built to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. Every page uses real headings in order, landmarks for the header, navigation, main content and footer, a skip link, and text that can be resized to 200 percent without loss of content. Text colours were chosen for a contrast ratio of at least 4.5 to 1 against their backgrounds (3 to 1 for large text and controls).

Everything that can be done with a mouse can be done with a keyboard: the menu, the questions and answers, the house drawing on the home page (its six areas are real buttons) and every link. Keyboard focus is always visible. When your device asks for reduced motion, smooth scrolling and hover transitions are switched off.

Photographs carry descriptions of what they show. The house drawing on the home page has a text description, and what each of its areas shows is also written out in words beside it.

What has been tested

Every page has been checked at widths from 320 to 1920 pixels for content running off the screen, with automated checks for text contrast, one main heading per page, image descriptions, broken images and broken links. The menu, the questions and answers and the house drawing's area buttons were operated in a desktop and a mobile browser.

On 15 September 2026 every page was also walked through using only the keyboard at desktop and mobile widths: every link and button could be reached in order with a visible focus outline, the skip link moved focus to the main content, and the menu, questions and drawing buttons worked with Enter, Space and Escape. The pages were also checked with reduced motion switched on, and automated Lighthouse accessibility checks scored the tested pages 100.

Known limitations

• The site has not yet been tested by a screen-reader specialist. The structure has been built for screen readers, but that is not the same as an independent assessment.
• The house drawing on the home page is a picture with a text description; the detail in it is repeated in words nearby rather than being navigable inside the picture.
• The tables in the guides scroll sideways on narrow phones.
• The Trustpilot website, which we link to, is run by another company and has its own accessibility statement.
