Innovation and excellence in science and health


The Group recognises the importance of providing a website that is accessible to all user groups, including the disabled. We have implemented the following accessibility features on this website to make it easier to use for people with disabilities.

Please e-mail if you have any questions or feedback regarding the accessibility of this site, or if you experience any difficulty using it.

Access keys

We have provided a series of keyboard shortcuts intended to help users who have difficulty in using pointing devices such as a mouse.

Most browsers support jumping to specific links by typing keys defined on the web site. On Windows, press ALT + the relevant access key; on Macintosh, press Control + the relevant access key. Then press Enter to activate the link.

All pages on this site define the following access keys:

  • Access key 1 – Homepage
  • Access key 8 – Privacy Policy
  • Access key 9 – Contact us
  • Access key 0 – Accessibility Statement (this page)
  • Access key T – Top of the page

These access keys have been chosen in accordance with the UK Government’s e-envoy guidelines.

If you have any questions or comments or if you use this facility and wish to suggest additional access keys, please contact

Structured, semantic markup: Headings and navigation menus

  • HTML heading tags are used to convey document structure. H1 tags are used for main titles, H2 tags for subtitles, and so on. For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT+INSERT+2.
  • 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.

Visual Design

All images used in this site include descriptive ALT attributes. Purely decorative graphics include empty ALT attributes.


We have checked the site’s font and background colour combinations against the different colour blindness conditions and ensured that all information is still clear.

If you wish to override the site’s colours, you can import your own style sheet.

Font sizes

You may change the font size to your preference either using the Site Tools menu provided, or through your browser:

  • In Internet Explorer, select View, then Text Size, and then your preferred size.
  • In Netscape select View, then Text Zoom, and then your preferred percentage size.

If you wish to override the site’s font settings, you can import your own style sheet.

Style sheets

This site uses Cascading Style Sheets ( CSS) for visual layout. If your browser does not support stylesheets, the use of structured semantic markup ensures that the content of each page is still readable and clearly structured.

If you wish, you may import your own stylesheet into this website:

  • In Internet Explorer select Tools, then Internet Options, and then Accessibility. Click on any or all of the three checkboxes to ignore colours, font styles or font sizes. In the same window you can change your style sheet by clicking the checkbox ‘format document using my style sheet‘ then simply browse to your style sheet and click OK.
  • In Netscape select Edit, then Preferences and then Appearance. You will then be given the choice to specify your own colours and fonts.


The site is fully accessible if scripting is unavailable.


Linking text have been written to make sense out of context.

Where appropriate, links have title attributes which describe the link in greater detail, for example to advise you if the link will open in a new window.

Accessible PDF

We recommend that users download the latest version of Adobe Acrobat to view Adobe PDF files.

Adobe Acrobat 6.0 software provides a number of capabilities that improve access for disabled users. Including the following:

  • Read Adobe PDF files aloud using standard operating system text-to-speech functionality
  • Give greater control when using screen readers
  • Evaluate the accessibility of an Adobe PDF file
  • Create accessible Adobe PDF documents and forms quickly
  • Reduce the size of tagged Adobe PDF files for faster download times

Please note some of our older archived Adobe PDF files may not be completely accessible when using screen readers.

Standards compliance

All pages conform at a minimum to Level A compliance as specified by the Web Content Accessibility Guidelines and endorsed by the Royal National Institute for the Blind (RNIB). The majority of Level AA and Level AAA requirements are also met.

We strive to obey the spirit of the Disability Discrimination Act (DDA) of 1995 with respect to the provision of services online, as required by the Disability Rights Commission (DRC).
