The Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018 require UK public sector websites and apps to meet the WCAG AA standard, now understood as WCAG 2.2 AA, subject to limited exemptions such as a disproportionate burden claim. The regulations took effect in September 2018, with phased deadlines for different content types.
A required accessibility statement must explain how accessible the site is, disclose any known gaps or exemptions, be reviewed regularly, and give users a way to report accessibility problems and request inaccessible content in another format.
