Our website is built to meet W3C AA standards for accessibility.
We use clear labels so visitors know where a link or button is taking them and the type and size of documents they are downloading. We have also used a clear design that takes account of people with visual impairments.
We've attempted to use plain English throughout the site to make the information easy to understand.
If you need to change the size of the text on our website, you can do this by changing your internet settings in the top right hand corner.
Magnify the screen
If increasing the text size doesn't make the text easy to see, you could try magnifying your screen. Most computer operating systems allow you to do this.
Select one of the options below to find out how to magnify your screen.
Windows 7 and Vista
Select the Start button, then 'Control Panel', then 'Ease of Access', then 'Ease of Access Center'.
Under 'Quick Access to common tools' select 'Start Magnifier'.
Windows XP/95/98/200/Millennium Edition
Select the 'Start' button or press the Windows logo key.
Select 'Programs' then press 'Enter', select 'Accessories' then press 'Enter', select 'Accessibility' then press 'Enter', select 'Magnifier' then press 'Enter'.
The magnifier will now be turned on and the settings box will display.
You can click in the magnification level box to change the level of magnification, or use the up and down arrow keys.
You can also minimise the magnifier settings box by clicking the minimise button or by pressing 'Alt' and 'Space', then pressing 'N'.
Mac OS X
Open the 'Finder' then select the 'Apple' menu, select 'System Preferences...', select the 'Universal Access' icon.
Select the 'Seeing' tab then select the 'Turn on Zoom' button.
To zoom in press 'Alt' and 'Cmd' and '+'. This zooms to your maximum level of magnification set in 'Zoom Options...'. The preview rectangle (black bordered box) shows the area of the screen that you will see at maximum zoom.
To step back or zoom out press 'Alt' and 'Cmd' and '–'. Move your mouse around the screen to view the magnified page.
To change the maximum and minimum zoom settings select 'Zoom Options...', then
use the 'Minimum Zoom' gauge bar to increase or decrease the magnification level.
When you have finished select 'Done' and, finally, select 'Close' (red button at the top of the 'Universal Access' window) to return to the Finder desktop.
To turn magnification on or off at any time, press 'Alt' and 'Cmd' and '*'.
We don't use colour alone to convey vital information.
All relevant images have alternative text descriptions explaining what the image is about. This description will be read out by screen readers and will be displayed if you hover your cursor over the image.
If the image is complex and cannot be described in just a few words, there will be a link below the image to another page with the full-text alternative.
All links to other websites will open up a new browser window.
If you want to return to our website after following an external link, you just need to close the new browser window.
