We aim to make our work accessible for everyone therefore our standard practice is to make sure the websites we design and produce comply to current programming standards and implement appropriately the accessibility guidelines provided by the World Wide Web Consortium (W3C).

Adjustable text size

You can choose to change the text size of this site to suit your requirements, just follow the appropriate instructions below:
  • In Internet Explorer – From the View menu select Text Size and then choose one of the five text sizes.
  • In FireFox – From the View menu select Text Size and then choose to Increase or Decrease the text size.
  • In Safari – From the View menu choose either Make Text Bigger or Make Text Smaller.
  • In all browsers – Hold down the CTRL button and scroll the mouse-wheel up or down to adjust text size accordingly.


Every image throughout the site has been tagged with an ALT attribute. ALT allows alternative description to be given for each image. This allows both screen readers and browsers which don't display images to represent a substitute description.

Colour contrast

This site has been designed with a black background and white text. We understand that some people do find this combination of colours hard to read, particularly with long paragraphs of text. We deliberated over this issue for a long time before deciding that we would go ahead with the style but also give an option for those who would prefer to read black text on a white background. If this is you, then you can drag the following bookmarklet to your toolbar which, when clicked, changes any site you are looking at to a white background version. This works for any site that you would prefer a white colour scheme, not just ours.

Standards compliance

All pages on this site validate as XHTML 1.0 Transitional and use standards-compliant Cascading Style Sheets (CSS) for layout. The links at the bottom of the page allow you to test pages with the W3C online validator for xHTML and CSS. If you spot anything that could be improved please let us know and we'll see what we can do.
