We are committed to meeting the requirements of the Disability Discrimination Act

We make every effort to ensure this web site complies with W3C Web Content Accessibility Guidelines. We are continually making improvements to meet these guidelines, and our web site has been designed with the following accessibility guidelines in mind:

Our pages are designed so that they can be viewed at a screen resolution of 1024 x 768 pixels. You can change the settings in the control panel if you are a Windows user: Start button > Settings > Control panel>Display>Settings

The standard support browser versions are: Firefox 4 (released March 2011), Chrome v10 (released March 2011), Internet Explorer 9 (released on March 2011), Safari 5 (released on June 2010.)

Page structure is conveyed using header elements. The site is free of frames and uses a cascading style sheet for visual layout. Tables are used for tabular data, but we have avoided using them to dictate the layout of a page wherever possible.

The style sheet uses relative font sizes and is written to display pages correctly in most commonly-used browsers. In early versions of browsers and browsing devices that do not support style sheets at all, the flow of the content has been tested to ensure it entirely retains its sense. If you find the text on these pages too large or small you can change the size to suit you. To do this you need to change the settings of your browser in the options, preferences or view menu (depending on which browser you use). For example, if you use Internet Explorer, go to the menu bar and select: View > Text size> (and then choose the size that suits you).

Images that convey important information have alternative text. Where an image is used for a decorative purpose the alternative text will be left blank. No information is exclusively conveyed using colour. A sitemap is available to provide information about the layout of the web site.

Links to our policies, including our privacy statement and this accessibility statement appear at the bottom of every page.
