Known Issues

The content listed below is non-accessible for the following reasons:

Issues with video, audio and images


Not all video that includes important visual information has an audio description that describes the visual content of the video, making this inaccessible to people who can’t see. This fails the WCAG 2.1 success criterion 1.2.5.

  • All video with audio content will have audio description that describes the visual content of the video by September 2021

All video content will have a transcript by September 2021.

  • Not all video content has captions that are synchronised to the audio content of the video, making them inaccessible to people who cannot hear. This fails the WCAG 2.1 success criterion 1.2.2.


  • Some images do not have a meaningful text alternative, so people using a screen reader cannot access the information. This fails WCAG 2.1 success criterion 1.1.1.

By September 2021, all images will have meaningful text alternative. Purely decorative images will have blank alt text and infographics and charts will have a link to a full description of the content.

Issues with contrast, use of colour and visual characteristics


Some elements have low contrast levels (e.g. the blue font used against the pale background), which can result in text being difficult to read, especially for people with low vision, poor eyesight or colour blindness. This fails the WCAG 2.1 success criteria 1.4.3.

  • We are working to fix this across the site over the coming months

Disproportionate Burden

We do not consider any of the accessibility issues to be a disproportionate burden and aim to make the site fully compliant by September 2021.

Documents (Word and PDF)

This site has a number of Word and PDF documents which were published before September 2018. These are not essential resources moving forward will not be replaced. If you experience any difficulties accessing these documents, please email

Video and Audio Content

This site has pre-recorded audio and video content that was published before 23 September 2020, which is exempt from the accessibility regulations as it does not contain instructional content.
