This guidance currently aligns with the Web Content Accessibility Guidelines (WCAG) 2.1 and is being updated to reflect WCAG 2.2. 

Organisations subject to the Web Accessibility Directive or the European Accessibility Act should refer to WCAG 2.2 (W3C.org), as compliance will be required when the revised EN 301 549 standard (PDF) is published in the Official Journal of the European Union in December 2026.
