We aim to make this site as accessible as we can.
Web accessibility means enabling people to view a web page the way they wish to view it with the equipment that they have available. In other words, making sure that as many people as possible can use a website, irrespective of physical impairment (such as loss of sight or restricted mobility), cognitive disability (such as dyslexia), or limited English language. It also means ensuring a website works on the broadest possible range of computer hardware and software, and its use does not depend on having the highest specification equipment or latest browser.
Our site is accredited by the Digital Accessibility Centre
In January 2011, we asked the Digital Accessibility Centre to carry out a comprehensive web accessibility audit of our site.
Each Digital Accessibility Centre Accreditation undergoes automated testing followed by a full manual technical review. The site is then tested by a team of experienced web analysts, all of whom have a disability. Over 70 hours of user testing has been conducted by members of the team with the following disabilities:
- low vision
- colour blindness
- impaired mobility
- learning difficulties
All testing is carried out in line with WCAG 2.0 level AA or above. Furthermore, the accessibility audit contributes towards conformance with BS8878.
Therefore we are delighted to announce that our site has been awarded the Digital Accessibility Centre's top accreditation mark in recognition of our work to ensure that the site is accessible to all.
We will continue to follow developments in web accessibility and remain committed to ensuring that people of all abilities can access the information and services that we provide on this site.
You can choose to enable a high-visibility layout on this site. This is especially suitable for partially-sighted people, and ensures that the site's content is kept in a single column, at a larger font size.
A layout using light text on a dark background, and a layout using dark text on a light background, are both available.
The high-visibility layout using light text on a dark background is currently enabled.

We have enabled the Readspeaker service on this site to help anyone who prefers to listen than to read, including people with impaired vision, dyslexia, or low literacy.
You do not need to install any special software on your computer to use this service.
To listen to a page, simply use the Have this page read aloud link at the top of the page. A control panel will appear and ReadSpeaker automatically starts reading the text of the page out loud.
In this control panel you can:
- Adjust the volume
- Pause the reading
- Stop the reading
- Restart the reading
- Choose "No sound?" if your browser does not support flash
- Choose "Settings" if you want to customize the behaviour of the service
Listen to selected text
To listen to a particular part of a page, select the text you'd like to hear by dragging your mouse over it, and then press the pop-up listen button which appears next to your mouse pointer. When you click the pop-up listen button, a smaller control panel will appear and ReadSpeaker will automatically start reading the text you have selected.
