This website fulfills the requirements as set out by the World Wide Web Consortium’s (W3C) Web Accessibility Initiative and has been carefully designed to comply with the latest legislation, which is concerned to ensure the accessibility of websites to as wide an audience as possible.


Several enhancements are available to you to help you use the site:

Firstly, if you find that the colours or images on the site are difficult to read, you should click the ‘Text Only’ link (the ‘T’ icon above). Clicking this link turns on text-only mode, which shows a more simple, image-free view of the pages.

It is also possible to increase (or decrease) the size of the text in the pages by either clicking on the ‘a’ or ‘a+’ icons above or by using the font size controls integrated in your web browser. Web browsers do this differently, but in general you should look at the options in the browser’s ‘View’ menu, failing which, consult your browser’s Help documentation. Here are some specific instructions for some of the more popular browsers.

  • Internet Explorer (all Windows versions): Go to the ‘View’ menu, ‘Text Size’, and select your desired setting. The default is medium. Alternatively, if you have a mouse with a wheel you can hold the CTRL key on your keyboard whilst scrolling up or down with the wheel to alter the text size.
  • Internet Explorer 5.1 (Mac): Go to the View menu and use the ‘Text Zoom’ feature.
    Apple Safari: Go the ‘View’ menu and use the ‘Make Text Bigger’ and ‘Make Text Smaller’ menu items. Alternatively you can use the option key with + or – to increase or decrease the text size.
  • Netscape 7 + (Mac and PC): Go to the ‘View’ menu and use the ‘Text Zoom’ feature to change text size. Alternatively you can use the CTRL key with the plus or minus to increase or decrease the size.
  • Mozilla (i.e. Firebird / Firefox / Camino, Mac and PC): Go to the ‘View’ menu and either click the ‘Increase Text Size’ or ‘Decrease Text Size’ menu items, or alternatively you can use the CTRL key with the plus or minus to increase or decrease the size.


This site fully complies with the latest web standards:

In order to provide good accessiblity some compromises have unfortunately had to be made in terms of full support for certain older browsers which do not support web standards, or support them unreliably or unpredictably. We strongly recommend that you use only the following browsers:


Internet Explorer 6 – available at Many people have this on their Windows-based PCs already. If you don’t have Internet Explorer, or if you have a version earlier than version 6, you should consider obtaining one of the Mozilla browsers (see below) instead, because they are small and quick to download.
Mozilla, Mozilla Firefox – all available at
Netscape 7 or 8 (in Internet Explorer or Firefox rendering mode)
Opera 8 or above

Apple Mac:

Apple Safari – available at
Mozilla, Mozilla Camino / Firefox – all available at


Mozilla Firefox – available at
The following browsers are not recommended on any platform – they will show the website but may not display the pages optimally:

Opera (Mac or PC, any version before 7)
Netscape (Mac or PC, any version before 7)
Konqueror (Linux, any version)

We appreciate that it might not seem easy or desirable to have constantly to upgrade your browser! If you do have an older browser, or one not on the list above, and you are unable or unwilling to change it, rest assured you will still be able to use the site, but you will not have the best viewing experience. Additionally most accessibility enhancements will not be available to you. Netscape 4 users may only view the site in text-only mode. We therefore again strongly recommend you upgrade your browser.
