We endeavour to make sure that every page on this website complies with the World Wide Web Consortium’s Web Content Accessibility Guidelines (WCAG 2.0) and has been built to achieve Priority Level 2 (AA) checkpoints.

To illustrate how we have made this site accessible, we have listed representative disabilities below and explained how this site meets the users’ needs.

Visual impairment

All pages on the site can be scaled to suit a user’s own requirement. Text – including menu items – is specified in percentage terms, meaning that it can be increased in size within the browser window for easier viewing.

The ability to support text scaling varies from browser to browser, but below are some guidelines for the more popular ones:

Internet Explorer	Select View > Text Size. You can then choose from a range of text sizes. Internet Explorer cannot resize images.
Chrome	Select Settings > Show advanced settings. In the section Web Content choose from a range of text sizes.
Mozilla Firefox	Select View > Text Size. You can then opt to increase or decrease your text size. Mozilla Firefox cannot resize images.
Opera	Select View > Zoom. You then have range of percentages to choose from. Opera scales everything on the page, not just text, so images will also increase in size as you increase the zoom factor.
Safari (Mac OS)	Select View. You can then opt to make text bigger or make text smaller. Safari cannot resize images.

Note that the same browser product can behave differently on different platforms. For example, Internet Explorer on an Apple device can scale images, whereas the Windows version cannot. Check with your supplier for details.

Hearing loss

Some content on this site cannot be accessed by the deaf or hard of hearing, namely some older embedded videos without subtitles. This content is mostly supplementary to the pages it appears on. Most of the videos we embed are our own, and we can provide transcripts on application by email. Text versions of the audio files are not available.

Physical

This site can be fully navigated without the use of a mouse. Keyboard access is supported by using standard shortcut techniques, and the entire site may be fully accessed using any voice-controlled computer and web browser.

Cognitive and neurological.

The layout of this site is uniform on all pages. The main menu is structured identically on all pages.

This site doesn’t contain animated images or flashing text.
