How Much Does a Website Accessibility Audit Cost in the UK? (2026 Pricing Guide)
If you've ever searched for what a website accessibility audit actually costs, you've probably noticed a problem: almost every result quotes prices in US dollars, references American disability law, and leaves UK businesses none the wiser. Pricing pages from UK providers tend to say "contact us for a quote" without giving you any concrete figures to work with.
This guide fixes that. We're publishing real UK pricing — in pounds — so you can budget properly, compare providers fairly, and decide what level of audit your organisation actually needs.
Whether you're a small business owner who's just learned about the Equality Act's website requirements, a public sector team preparing for your next GDS monitoring cycle, or an agency looking for a white-label audit partner, this page gives you the numbers.
What Does a Website Accessibility Audit Actually Cost in the UK?
Here's the short answer: a professional website accessibility audit in the UK typically costs between £500 and £10,000+, depending on the size of your website, the depth of testing, and the provider you choose.
For most small-to-medium businesses with a fairly standard website (a homepage, a handful of service pages, a contact form, maybe a blog), you're looking at somewhere between £600 and £5,000.
Here's how that breaks down across the market:
These figures are drawn from published pricing, Government Digital Marketplace rate cards (G-Cloud 14), and GOV.UK estimates.
For context, the GDS estimates £3,000–£7,000 for a typical public sector website audit. The Department for Education has put the average closer to £8,000–£10,000. Slough Borough Council received quotes of £12,100–£18,000 — and Manchester City Council calculated a bill of £282,000–£658,000 to audit its 94+ websites. Enterprise-scale accessibility gets expensive fast.
But the biggest cost driver isn't the number of pages on your site. It's the number of unique templates and interactive components. A 500-page site built on 8 templates is far cheaper to audit than a 50-page site with 30 different interactive widgets. We'll cover all the cost factors in detail below.
What Affects The Cost of an Accessibility Audit?
Not all audits are created equal. Understanding the cost drivers helps you compare quotes on a like-for-like basis and avoid paying for more (or less) than you need.
- Site size and complexity is the primary factor, but it's often misunderstood. Auditors don't test every single page on your site — they test a representative sample of unique page templates and components. A brochure site with 5 templates is straightforward. An e-commerce site with product pages, checkout flows, account dashboards, search and filtering, and a blog requires significantly more testing time.
Dynamic content, single-page applications (SPAs), and custom interactive widgets like date pickers, carousels, and modal dialogues all add complexity. If your site is built on a CMS with consistent templates, that works in your favour.
- The level of testing has the most dramatic impact on price. There are three tiers, and they catch very different amounts of issues:
Automated scanning alone is the cheapest option (free, and often £24–£300 per year for a tool subscription), but here's the critical caveat: automated tools can only detect around 30–40% of WCAG success criteria. The UK Government Digital Service tested 13 automated tools and found the best one caught only 40% of deliberately introduced barriers. The worst caught just 13%. A passing score from an automated tool does not mean your site is accessible.
Manual expert testing is where a qualified auditor works through your site using keyboard navigation, screen readers (like NVDA and VoiceOver), and systematic WCAG checks. This catches the 60–70% of issues that automation misses — things like whether alt text is actually meaningful, whether heading hierarchy makes logical sense, and whether complex widgets actually work with assistive technology. This is the standard for a professional audit and typically costs £1,500–£5,000+.
User testing with people with disabilities is the gold standard. Real users who rely on assistive technology in their daily lives test your site and report on their actual experience.
- Conformance target matters too. Almost all audits target WCAG 2.2 Level AA, which includes around 50 success criteria across the four POUR principles (Perceivable, Operable, Understandable, and Robust). This is the standard referenced by the Equality Act, PSBAR, and the European Accessibility Act. Testing to Level A only is cheaper but won't satisfy compliance requirements. Level AAA is rare and significantly more expensive.
- Assistive technology coverage varies between providers. A basic audit might test with keyboard navigation and one screen reader. A comprehensive audit tests across NVDA and JAWS (Windows screen readers), VoiceOver (macOS and iOS), TalkBack (Android), Dragon NaturallySpeaking (voice control), and ZoomText (magnification).
- Remediation support is where providers diverge most. Some deliver a PDF report and leave you to it. Others — including us — provide detailed technical logs with code examples, executive summaries for stakeholders, and prioritised remediation roadmaps that tell your developers exactly what to fix first.
- Retesting is an often-overlooked cost. Most providers charge 50–70% of the original audit fee to retest after you've made fixes. Some providers include one retest in their initial package — always ask.
- The current state of your site also plays a role. A well-built site with minor issues is faster (and cheaper) to audit than one with deep, systemic accessibility failures that require extensive documentation.
Do You Actually Need an Accessibility Audit? (The Legal Position)
In the UK, the legal requirement comes from two main sources.
The Equality Act 2010 requires all service providers — including anyone with a website — to make "reasonable adjustments" for people with disabilities. This duty is anticipatory, meaning you're expected to address barriers proactively, not just react to complaints. The Act doesn't name WCAG specifically, but WCAG 2.1/2.2 Level AA is the widely accepted benchmark that courts would reference when assessing whether reasonable adjustments have been made. The EHRC has confirmed website accessibility as a strategic enforcement priority.
The Public Sector Bodies Accessibility Regulations 2018 (PSBAR) go further: all UK public sector websites and mobile apps must meet WCAG Level A and AA. Since October 2024, WCAG 2.2 has been the monitoring standard. GDS actively monitors compliance — they tested 1,203 websites and 21 mobile apps between 2022 and 2024, identifying nearly 30,000 accessibility issues. If you're in the public sector, an audit isn't optional.
The European Accessibility Act (EAA), which came into force in June 2025, adds another layer. While it doesn't apply directly in the UK, any UK business selling to EU consumers must comply for those products and services. Multiple law firms have confirmed this creates a "dual compliance" situation for UK organisations with EU customers.
For charities, the position is equally clear: the Equality Act applies to you too.
Can't I Just Use Free Tools Instead?
Free tools are genuinely useful — and we'd encourage you to use them. They're an excellent starting point. But they have hard limits that every business should understand.
WAVE (by WebAIM) is a brilliant browser extension for spotting obvious issues like missing alt text, colour contrast failures, and heading structure problems. axe DevTools Free (by Deque) is the industry-standard engine with a zero-false-positive policy. Google Lighthouse, built into Chrome, gives you a 0–100 accessibility score — but a score of 100 does not mean your site is accessible. Lighthouse tests a smaller subset of rules than axe and covers only a portion of WCAG.
The fundamental limitation is this: automated tools can only detect 30–40% of WCAG success criteria. The remaining 60–70% requires human judgment — things like whether alt text is actually meaningful, whether keyboard navigation is usable (not just technically functional), whether "read more" links make sense out of context, and whether complex interactive components work with assistive technology.
It's worth noting that the FTC fined accessiBe $1 million in January 2025 for falsely claiming its automated overlay tool could make any website WCAG-compliant. One in four accessibility lawsuits in 2024 targeted sites using overlay widgets.
Free tools catch the low-hanging fruit. A professional audit catches the other two-thirds. If legal compliance, genuine inclusivity, or risk mitigation is your goal, free tools alone won't get you there.
We offer a free video accessibility audit — a 5-minute recorded walkthrough of your site highlighting the key issues — that goes beyond what free tools alone can show you. No commitment required.

Why Accessibility Matters Beyond Compliance
The business case for accessibility is stronger than many organisations realise.
Disabled people and their households in the UK have an estimated annual spending power of £274 billion — known as the "Purple Pound." There are 16 million people in the UK with disabilities: 1 in 5 working-age adults and 42% of pension-age adults. This is not a niche audience.
Research from the Click-Away Pound study found that UK retailers lose an estimated £17.1 billion annually because disabled customers leave inaccessible websites. 69% of disabled customers with access needs will simply leave a site they find difficult to use. 83% limit their shopping to sites they already know are accessible. And only 8% bother contacting the site owner about problems — meaning most businesses have no idea they're losing customers.
Meanwhile, the WebAIM Million 2026 report found that 95.9% of the top one million homepages had WCAG 2.2 failures, with the average page containing 56.1 errors. Level Access tested the top 100 UK retail websites in July 2025 and found 84% had critical accessibility barriers on their homepages. 100% had at least one WCAG violation.
The gap between where most websites are and where they need to be is enormous. That's precisely why the accessibility testing market is growing at 6.42% per year in the UK — and why getting ahead of the curve is a competitive advantage, not just a compliance exercise.
Accenture research shows companies leading in disability inclusion achieve 28% higher revenue growth. Accessibility improvements — clearer navigation, better form design, proper heading structure — benefit every user, not just those with disabilities.
Frequently Asked Questions
How much does a basic website accessibility audit cost in the UK? A basic accessibility health check or review starts from around £500–£900 with most UK providers. This typically covers automated scanning plus a manual review of your homepage and key templates, with a summary report of critical issues. For a thorough check at this level, our Quick Health Check starts at £600.
What's included in a full WCAG compliance audit? A full audit follows the WCAG-EM methodology and tests your site against approximately 50 success criteria at WCAG 2.2 Level AA. It typically includes testing 10–15 unique page templates, keyboard and screen reader testing, a detailed findings report with severity ratings, and a prioritised remediation plan. Better audits include code examples showing developers exactly how to fix each issue.
How long does an accessibility audit take? A basic health check can be completed in 5–7 working days. A full WCAG compliance audit typically takes 10–15 working days, depending on site complexity. Enterprise audits with user testing may take longer.
What's the difference between an automated scan and a manual audit? Automated tools (like WAVE, axe, or Lighthouse) can detect around 30–40% of accessibility issues — things like missing alt text, colour contrast failures, and missing form labels. The remaining 60–70% of WCAG criteria require human testing: checking whether alt text is meaningful, whether keyboard navigation is usable, whether complex widgets work with assistive technology, and whether the site is cognitively accessible.
Do I need WCAG 2.1 or WCAG 2.2? WCAG 2.2 is the current standard (published October 2023) and has been the UK public sector monitoring standard since October 2024. It adds nine new success criteria on top of WCAG 2.1, with a focus on cognitive accessibility and mobile usability. Any new audit should test against WCAG 2.2.
How often should I audit my website? A full audit should be conducted at least annually, or whenever you make significant changes to your site's design, functionality, or content management system. Between audits, ongoing monitoring catches regressions before they become systemic problems.
Is an accessibility audit legally required in the UK? There's no law that specifically requires an "audit." However, the Equality Act 2010 requires you to make reasonable adjustments for disabled users, and PSBAR requires public sector sites to meet WCAG AA. An audit is the most practical way to understand your current compliance position and demonstrate due diligence. With the EHRC treating website accessibility as an enforcement priority, having documented evidence that you've assessed and addressed barriers is increasingly important.
How much does remediation cost after an audit? Remediation costs vary enormously depending on the number and severity of issues found, your site's technology stack, and whether you have in-house development resources. Simple fixes (adding alt text, fixing contrast, adding form labels) can often be done quickly. Structural issues (navigation redesign, widget rebuilds) take longer. A good audit report will prioritise issues so you can address the most critical barriers first within whatever budget you have.
