Technical standards

We intend to maintain this website so as to conform with international Web Content Accessibility Guidelines.

If you require any of our information in another format, or help finding a document, please contact us.

Accessibility help

All our web pages have an invisible link at the top of the page that allows users with screen-reading software to skip directly to the main content.

Links to other pages in our website open in the same window. To return to the previous page, use the browser ‘back’ button.

Links to external sites, and to downloadable documents open a new browser window. To return to the previous window, close the new window.

Adobe PDFs

Many documents are in Adobe’s Portable Document Format, abbreviated to ‘PDF’.We are amending them; documents over five pages long will have a ‘live’ table of contents, allowing users to jump directly to the page required. To return to the beginning of the document, press your keyboard’s ‘home’ key.

Further information

We are always pleased to receive feedback. For help or to request documents in an alternative format if they are inaccessible on our site, please contact us.
