We understand the importance of web accessibility, and have designed
and developed this website according to both recommended guidelines
and best practice standards.
This website complies with W3C (World Wide Web Consortium) Web
Content Accessibility Guidelines. Briefly explained, these guidelines
are broken down into 14 checkpoints, which are then sub-divided into
three levels of priority.
Priority 1, where all checkpoints must be satisfied. Priority 2,
where all checkpoints should be satisfied. Priority 3, where all
checkpoints may be satisfied. The accessibility of any website is
typically explained by it's compliance
to these checkpoints. Level 'A' means all Priority 1 checkpoints have
been satisfied. Level 'AA' means all Priority 2 checkpoints have been
satisfied. Level 'AAA' means all Priority 3 checkpoints have been satisfied.
With this in mind, we have designed and developed this website to
a minimum of level 'A' compliance and a vast majority of level 'AA'
For full details of the W3C Web Content Accessibility Guidelines,
We have included the use of Access Keys to allow users to easily
navigate this website using only a keyboard. We have used the recommended
UK Government access keys standard where possible, which is based
on the widely adopted numbers system.

Text Language and Style
We have used plain language, which is easy to understand and avoids
jargon. Any large sections of text have been broken into manageable
chunks, eg. paragraphs, to make them easier to comprehend.
Text is presented at an easy to read size by default, and is spaced
to maximise legibility. All links are clearly marked using distinctive
Use of Images
We have ensured that all images on this website have alternative
text elements, commonly referred to as alt text or alt tags.
This allows text based browsers and other accessibility technology
including screen readers
to clearly identify and describe what the image conveys to users.
So as not to overwhelm users, we have not applied alt text to superfluous
or purely decorative imagery, but rather kept the alt text to only
sensible elements on a given page.
We have made an effort to ensure live text or accessible text
technologies are used instead of graphics wherever possible on this
website. This allows both more control over text sizes by the user,
and increases page
download time allowing users quicker access to the website.
We have optimised all images across the website to ensure they
download as quickly as possible, whilst retaining good visual quality.
Rich Media Content
This website makes use of a variety of rich media content, including
video and animation. We have ensured all rich media elements have
alternative static imagery, accompanied by alternative text elements
what is being conveyed. In addition, all video elements on the website
are accompanied by captions explaining what is being depicted.
Web Browser Compatibility
We have tested this website to ensure its full compatibility with
the following specific web browsers on both PC and Mac platforms:
Internet Explorer 6.0 and above, Mozilla Firefox 2.0 and above,
Safari 1.0 and above.
We would expect full or close to full compliance with all other web browsers.
We've aimed to make this website accessible and comply with the W3C
guidelines wherever possible. It's been fully tested and we're really
happy with it, but we'd love to know what you think!
