We are constantly striving to make our site as accessible as possible to people with visual and other disabilities. This is an ongoing process and we plan to add many new features as the site evolves.

In particular we try to ensure that charts and images have relevant and clear ALT text which explains the key points of the chart without adding unnecessary text for the purposes of search engine optimisation.

Furthermore we invariably use text links rather than graphics and additionally provide videos with clear narratives which can be viewed as an alternative to reading the site's text and graphics.

If you have any comments or suggestions please contact us. We will aim to take your views into consideration as part of our ongoing commitment to accessibility.
