Prior to September 2020, UKHSA's Khub pages were used to house content which wasn't suitable for HTML web pages or not fully accessible.
Since September 2020, however, Khub falls under the same accessibility requirements as GOV.UK and therefore we are being more strict about what can be published there.
As a result, document types such as PowerPoint slidedecks and infographics need to have the same content published elsewhere in accessible format, ideally as HTML web pages.
Slidedecks in particular can no longer be used as a primary way to publish information. Information just be published as an HTML web page or PDF, with slidedecks only permitted for presentation purposes only.
