Accessibility
We recognise the importance of accessibility and have worked to ensure that our "website and its content must be written to be as accessible as reasonably possible". Our target is to conform to WCAG 2.0 AA Standard as set out by the Worldwide Web consortium (W3C), who set globally agreed standards on accessibility.
Web accessibility means access to the internet by everyone, regardless of disability. This means that people with disabilities should be able to perceive, understand, navigate, and interact with web sites and online applications and that these should work well with the assistive technologies which some people with disabilities use to access the internet - such as screen readers, screen magnifiers and text-to-speech devices.
If you have any problems using our site or require information in another format, please contact us. There are also options within your browser that can help you access web sites more easily and the most common one is outlined below.
Access keys
Access keys let you navigate around the website without using your mouse. They can be used to jump directly to different sections of the site or certain areas within a page.
You can navigate to different sections using your browser as follows:

|---|---|
| Internet Explorer (PC) | Hold down the ALT key, press the number of the access key, release both keys then press ENTER. |
| Firefox, Mozilla (PC) | Hold down the ALT+SHIFT key and press the number of the access key. |

Please note that some assistive technology tools such as the IBM HomePage Reader and WindowEyes already make use of the alt+[access key] combinations. As such, users of these tools will not be able to use these access keys.
