Web Accessibility Certification

The seal that certifies your organisation's commitment to digital accessibility.

Our web accessibility certification validates that your site complies with WCAG 2.2, EN 301 549 and current regulations. You receive a recognisable conformance seal, a detailed technical report and continuous support to maintain compliance.

What is Web Accessibility Certification?

Web accessibility certification is the process by which a team of specialist auditors evaluates your website against WCAG 2.2 Level AA success criteria and the European standard EN 301 549. The result is a conformance seal you can display on your website and communications, together with a detailed technical report. Unlike automated seals based solely on scanning tools, our certification combines automated evaluation with expert manual review: we test with screen readers (JAWS, NVDA, VoiceOver), keyboard navigation, 200% zoom and content comprehension analysis. This covers 100% of WCAG criteria, not just the 30-40% that can be automated. Certification is not a one-off event: we include a maintenance plan with periodic monitoring so your site maintains conformance through content updates, redesigns or new features.

It depends on site size and complexity. A typical corporate site: 4-6 weeks including audit, remediation and verification. Large sites or complex web applications: 8-12 weeks.
The certification is valid for 12 months. We recommend continuous monitoring and annual re-certification to maintain conformance through site changes.
We deliver the detailed report with all issues and support your team through remediation. Once resolved, we perform final verification and issue the seal.
The TWA seal certifies compliance with international standards (WCAG 2.2, EN 301 549). While not a governmental certification, it is recognised as technical compliance evidence by regulators.
