Searching for a freelance accessibility tester in the UK usually means you need hands-on, manual testing of a website or app against WCAG standards. What that actually involves is quite different from what a lot of providers deliver.
What manual accessibility testing actually covers
Automated tools like axe-core, Lighthouse, or WAVE are useful for quick wins. They catch structural issues: missing alt text, empty form labels, poor colour contrast ratios. The research consensus is that automated tools catch around 30 to 40% of real-world WCAG failures.
The other 60 to 70% requires manual testing. That includes:
- Keyboard-only navigation through every interactive element
- Screen reader testing on NVDA with Chrome, JAWS with Edge or Chrome, and VoiceOver on macOS and iOS
- Checking focus order, skip links, and modal trap behaviour
- Testing ARIA live regions and dynamic content updates
- Review of error identification, timeout handling, and form validation
- Colour contrast in interactive states (hover, focus, selected)
- Cognitive load assessment: plain language, consistent navigation, no sensory-only instructions
A freelance accessibility tester needs to do all of this competently, not just run a browser plugin and export the findings.
The difference between a tester and a consultant
A tester produces findings. A consultant produces findings plus remediation guidance, communicates with developers and designers, and ideally helps the team understand how not to repeat the same mistakes.
For a one-off audit, a skilled tester is often enough. If you need someone embedded in a product team or helping you shift accessibility left into design and development, a consultant is the better fit.
I do both, depending on what the project needs.
What good findings look like
A WCAG audit from a competent freelance tester should give you:
- Each failure mapped to the specific WCAG success criterion it violates (not just a tool rule ID)
- The impact level: critical, serious, moderate, minor
- The specific element or page affected
- A clear explanation of what the user experience problem is for a disabled person
- A recommended fix that a developer can act on without needing to look anything up
Vague findings like “improve keyboard navigation” or “check screen reader compatibility” are not useful. Specific findings are.
UK-specific demand for accessibility testing
The UK has had public sector accessibility regulations since 2018. Combined with the Equality Act 2010 and the growing EAA obligations for EU-facing products, demand for accessibility testing in the UK is consistent and increasing.
Common triggers for hiring a freelance accessibility tester include:
- Annual accessibility statement review for public sector sites
- Pre-launch WCAG audit for a new product
- Failing a GDS service standard assessment
- Responding to a legal complaint or reasonable adjustment request
- Supplier due diligence for enterprise procurement
