Accessibility statement

Conformance status

This page is designed to conform to WCAG 2.2 Level AA (Web Content Accessibility Guidelines), the current W3C Recommendation, which also satisfies WCAG 2.1 Level AA and WCAG 2.0 Level AA. ADG has not commissioned an independent, formal accessibility audit; conformance has been assessed by ADG itself through manual review against the published success criteria. On that basis this page is partially conformant with WCAG 2.2 Level AA: partially conformant means that most content meets the standard, but some parts have not yet been independently verified.

Measures ADG has taken

This page uses an animated video as a full-page background. It plays muted, with no essential information conveyed only through it, and a control in the lower right corner of every page lets you pause or resume it at any time; it also pauses itself automatically if your device is set to reduce motion. Beyond that: semantic HTML landmarks and heading structure; a skip-to-content link; form fields with visible labels and autocomplete hints rather than placeholder text alone; keyboard focus indicators chosen for visibility against this page's dark background specifically, not just inherited from the site's general styling; a layout that reflows and resizes without loss of content; and an enquiry form that is a standard HTML submission underneath its JavaScript enhancement, so it still works with JavaScript disabled.

Technical specifications

This page relies on HTML, CSS, and a small amount of JavaScript used to enhance the enquiry form and the video's pause control. No third-party embeds, web fonts, or tracking scripts are loaded.

Known limitations

ADG has not yet completed an independent accessibility audit or testing with assistive-technology users. This is also a temporary, one-page holding site (see the note on Terms of use) -- it will be replaced by ADG's full website once that has been reviewed page by page, and this statement will be reviewed again at that point rather than assumed to still apply unchanged.
