Disclaimer

This certificate was issued on the 24th of April 2025 and represents the state of the pages audited on this date. Any further changes after the accreditation date are not covered by this certificate.

The issues identified in the initial audit represent the specific accessibility barriers encountered during testing at the time of assessment. This certification applies solely to the issues documented in the original audit report and confirms that the remediation work undertaken to address those findings was assessed during subsequent retesting as satisfactorily meeting the applicable Web Content Accessibility Guidelines (WCAG) success criteria.

Please note that additional instances of the same or similar accessibility barriers may exist elsewhere within the service. Any pages, components, user journeys, functionality, or content that were not included within the defined scope of testing have not been assessed and are therefore not covered by this certificate.

This certificate does not constitute confirmation that all accessibility issues within the service have been identified or remediated. To ensure ongoing compliance with WCAG, responsibility for ensuring that the same or equivalent remediations are applied wherever those barriers exist, including any areas not covered by the original audit, remains with the client.

We audited the service against Web Content Accessibility Guidelines v2.2 level A and level AA to test how accessible the serviceis, using the Website Accessibility Conformance Evaluation Methodology (WCAG-EM) to evaluate conformance.
