We are committed to making as accessible as possible.

We are committed to making this site as accessible as possible. By this we mean making sure that our content is available to users with physical or sensory impairments and who use assistive technology like screen readers and to those users with slower internet connections.

Why we want to be accessible

Like all providers of goods and services we are obliged by law to take steps not to exclude people with disabilities. In addition, we recognise the internet offers an opportunity to make information accessible to more people than any other medium. 

Accessibility tools

Every effort is made to ensure that our website is accessible across all platforms and browsers. We would strongly recommend, however, that you upgrade your browser to the latest version for optimum experience.

The site’s text size can be adjusted according to your preferences via options in your browser's 'View' or 'Page' menu.

This can also be done via your keyboard:

  • PC users: Select 'Ctrl' and '+' or '–'
  • Mac Users: Select 'Cmd' and '+' or '–'

The following online resources are available to help you change your browser settings:

Some of the resources on the website are available to view or download in Portable Document Format (PDF). You will need Adobe Acrobat Reader to read PDF files, which can be downloaded for free from the Adobe website.

Technical details

We have provided the features set out below to improve navigation for screen reader users, keyboard navigation and users of text-only browsers.

Structured, semantic markup: headings and navigation menus
HTML heading tags are used to convey the document layout. H1 tags are used for main titles, H2 tags for subtitles, and so on. Navigation menus are marked up as HTML lists. This ensures that the number of links in the list is read out at the start and it can be skipped easily.

Where an image conveys important information, alternative text will be provided. If the image is used for a decorative purpose the alternative text will be left blank.

Style sheets, fonts, colours
This site uses software called Cascading Style Sheets (CSS) to control all of the presentation and layout. If your browser or browsing device does not support style sheets, the use of structured semantic markup ensures that the content of each page is still readable and clearly structured.

Font sizes and colours can be changed by using your own custom style sheets or browser settings. The BBC has an excellent guide on how to do this for various browsers and systems.

The content on this site has been written and formatted to make it accessible and the content areas of the site are fully accessible if scripting is unavailable.

Standards compliance
The pages on this site conform at a minimum to Level A compliance as specified by the Web Content Accessibility Guidelines. This site also meets the majority of Level AA and AAA requirements. Most of the pages are valid HTML and use structured semantic markup. The CSS also validates.
