Website accessibility

We're committed to making our website accessible to the widest possible audience and we're always working to make sure we meet internationally accepted standards. Learn more about how we design our website and how you can access it.

We aim to make sure our website meets the Web Content Accessibility Guidelines Version 2.2 (WCAG 2.2) at a minimum Double-A (AA) rating. The guidelines, drawn up by the World Wide Web Consortium (W3C), explain how to make web content more accessible to people with disabilities.

Our site should be accessible to people who use assistive technology like screen readers or speech-input software, and to those unable to use a mouse or a pointing device.

Accessibility features on this site include:

• All controls work with a keyboard alone
• Strong colour contrasts so it's easy to read text and graphics
• Page layout resizes according to the width of your device
• Headings are readable through screen readers
• Tables are laid out in tabular form with headings and summaries
• Cascading style sheets (CSS) determine the presentation of our website – this assists those using screen-reading devices
• Most PDF files are tagged 
• Non-decorative images include text alternatives (alt text) for screen readers
• Link text is descriptive – we don't use 'click here'

We aim to make our website available to as many people as possible, regardless of the technology they use.
