This website has been built to comply with accessibility guidelines. In order to do this we’ve used techniques supported by modern browsers (Internet Explorer 6.0 or later, Safari or Mozilla Firefox).

Modern browsers also make navigation faster and allow us to provide more advanced content and features. This means that if you are using an older browser, you may be viewing our website in a more simplified form.

The site has been designed to make it as easy and quick to navigate as possible. 
Use the menu at the top of the web page to enter the main sections of the site. Once you are in a section, you can get to the more detailed information via the menu that appears on the left-hand side of the screen.


We have built this website to meet W3C accessibility standards. These standards aim to give all users equal access to websites.

To make this website as easy as possible for you to read, you can control the size of the text and the contrast between the text and the background. We have also implemented access keys. These are keyboard shortcuts that you can use instead of a mouse. You can find more information about these options on our Accessibility page.
