A big question. Websites suffer from varying levels of inaccessibility. To keep on the right side of UK Government Law, your website should meet certain basic criteria.
Your website should meet basic industry good practice benchmarks, like valid HTML and CSS. Then, your website should meet at the very least Priority 1 (of the W3C WAI WCAG). At Hobo we build websites to a much higher spec, but these are the basic standards your website should meet.
If you’d rather simply be told whether your website does or does not comply with the UK Disability Discrimination Act, then contact Hobo.
On this site you can find out some information that can help you test the accessibility of your site, and give you some information about what level of accessibility compliance you should be aiming to achieve at a basic level.
In the UK, a new British Standard for web accessibility is expected in 2009 – BS 8878 – be sure to have a look at that when it is published.
