Welcome to the ASH website accessibility page. We have worked hard to make this website as accessible and easy to use as possible, regardless of computer literacy or ability, and in compliance with the Web Accessibility Initiative (WAI) guidelines.

Recent versions of the main browsers will allow you to customise your browsing experience by adjusting the settings for colour contrasts and font size. However, if you have any questions or comments, do feel free to email us at

Standards compliance

This site aims to be standard compliant with many tests used and lots of semantic markup e.g. H2 tags are used for main titles, H3 tags for subtitles. For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT INSERT 3.

All content images used in this site include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
Complex images include LONGDESC attributes or inline descriptions to explain the significance of each image to non-visual readers.

Visual design

This site uses cascading style sheets for visual layout.

This site uses only relative font sizes, compatible with the user-specified “text size” option in visual browsers.
If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
