This site uses only relative font sizes and therefore is compatible with the user-specified text size option in visual browsers.

The text size can be changed in Internet Explorer through the View > Text Size menu. And in Mozilla/Netscape, through the View > Text Zoom menu.

All images that are used to illustrate content include the alt attribute to provide descriptive text alternatives. All of our products have a zoom feature allowing more detailed viewing.

A title attribute has been added to links which describe the link in greater detail. If the text of the link provides a clear explanation of the 'target' then the title attribute has not been used.

The site uses minimal client-side scripting to assist the viewing of Frequently Asked Questions, form validation & some menu links.

This site has been tested in all modern browsers on Windows and Macintosh. All pages on this site use structured semantic markup which means that if your browser or browsing device does not support stylesheets, the content of each page is still readable and is presented in order.

We have attempted to follow relevant standards and good practice for accessibility and usability while developing the website.

We have also tested the site extensively in a wide range of browsers and settings to ensure the site functionality is available to as many users as possible.

Constantly improving

If you come across a part of our site that is difficult to use or could be improved in terms of accessibility or usability we apologise and would be very grateful if you could contact us.
