Quick Answer
UK website accessibility law rests on two pieces of legislation. The Equality Act 2010 requires reasonable adjustments for disabled users across all sectors, including private business websites. The Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018 (PSBAR) goes further for public sector organizations, requiring proactive compliance with WCAG 2.2 Level AA (which replaced 2.1 AA as the assessment standard on October 1, 2024) and a published accessibility statement listing any content that does not yet meet the standard. The Government Digital Service carries out unscheduled audits of public sector websites on behalf of the Cabinet Office. An accessibility audit benchmarked against WCAG 2.2 AA gives both public sector bodies and private businesses evidence of compliance and a clear remediation plan.
