Our website conforms to Success Criteria Level 2 (AA) of the Web Content Accessibility Guidelines 2.1 (WCAG 2.1). This means that every visitor should be able to access all the information and services that we provide through our website.

We welcome suggestions and feedback to improve accessibility on this website. If you are experiencing any difficulties accessing the information on our pages, please contact us.


Change view

You can change the way this website looks to suit your needs. The settings differ depending on your browser (Internet Explorer, Firefox, Google Chrome or Safari), but most offer some or all of the features explained in the following 'Change font size' or 'Change colour combination' sections.

Change font size

You can adjust the size of nearly all the text on this website by using the font size setting in your browser. This setting is found in the 'View' menu of most browsers - please see more instructions below.

  • Internet Explorer, go to 'view', 'text size'. Select the text size you require.
  • Firefox, go to 'view', 'text size'. You can increase or decrease the text size as required.
  • Safari, hold down the command key (Apple key) and select '+' to increase the text size or '-' to decrease the text size.


Change the colour combination

Some browsers allow you to change the default font and background colours you use to make them high contrast. This is useful for those with a visual impairment. These settings are usually found in the 'Options' or 'Preferences' menus. Alternatively, use the 'Change colours' option on this website, which can be found at the top of the screen in the grey header bar.


Use a 'plain' layout

Many browsers allow you to remove all styling from a web page by turning off the website’s 'style sheets'. If your browser supports this setting you will most likely find it in the 'View' menu.


Keyboard access

Most browsers let you move from link to link using the TAB key. The current link will be highlighted in yellow. To move backwards, hold down SHIFT and press the TAB key.

At the top of each page there is a selection of links to the main parts of the page (site map, navigation and search for example). These links are hidden until they are skipped to, at which point they appear in a yellow box at the top left of the page.


Access keys

Access keys are keyboard shortcuts to common pages on a website. This website does not use Access Keys because evidence suggests that they interfere with the keyboard controls of many browsers and screen readers.



All of the documents linked within this site are in PDF (Portable Document Format). Links to these documents will open a new window. PDF's can be viewed in Adobe Acrobat Reader, which is available to download for free by visiting Adobe's website. You will also find other free tools that will convert PDFs to plain text or HTML and further information about PDFs and accessibility.


Skip to navigation

Skip to navigation provides a link that allows you to skip directly to the main navigation of the webpage, i.e. 'Home', 'About us', etc. This is to assist blind or visually impaired users and people who use screen readers.


Screen reader

Our site should be compatible with recent versions of the following screen readers:

  • Window Eyes;
  • VoiceOver;
  • NVDA;
  • Jaws;
  • ZoomText;
  • Supernova screen readers;
  • MAGic.
