This website has been designed to make it as widely accessible as possible. This page gives information on features included within the site.

Standards Compliance

All pages validate as HTML5.
All pages use structured semantic markup.


We’ve used a common accessible design throughout this site rather than providing text only pages for disabled users.

Links and navigation

Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
Wherever possible, links are written to make sense when read out of context. Many browsers (such as JAWS) can extract the list of links on a page and allow you to browse the list separately from the page.
Link text is never duplicated: two links with the same link text always point to the same web address.

Graphics, pictures and images

Where we’ve used graphics, pictures and images, we’ve included text descriptions ('Alt-Tags'), to comply with internationally recognised Web accessibility guidelines. All graphical navigation buttons are similarly 'Alt-tagged'. Where graphical images are just for decoration they have NULL alt text (alt=“”).


We’ve followed 'use-of-English' guidelines, including those set out by Mencap and the Plain English Campaign, so that you’ll find this web site easy to read and understand.


• Most of this site is accessible but we’re continuing to work on a couple of areas to make them as useable as possible. The Our performance and Better, broader, faster sections, contain a lot of tables and detailed information. They currently use Alt-Tags and we’re working to make them more accessible.

The information in these sections is updated every quarter and previous reports are made available as PDFs. At the moment the PDFs on the site aren’t accessible and we’re working to make as many of them accessible as soon as possible.
