Website Accessibility Audit Cost UK: Pricing Guide

Quick Answer

A professional website accessibility audit in the UK typically costs between £500 and £10,000 or more, depending on site size and audit depth. For a standard small business website with a homepage, a handful of service pages, and a contact form, expect to pay somewhere between £600 and £2,500. Charity and government-adjacent providers, such as AbilityNet, charge a fixed £4,950 plus VAT regardless of site size, for a more formal, deeply credentialed review.

UK Pricing by Provider Tier

Provider Type	Typical Price	Best Suited For
Free automated tools	£0	A quick first check, not a substitute for a full audit
DIY paid checker tools	£30 to £120 per month	Ongoing monitoring alongside a manual audit
Small UK agency manual audit	£600 to £2,500	Most small business websites
Charity/government-grade audit (e.g. AbilityNet)	£4,950+ VAT fixed	Businesses needing the highest-credibility evidence
Public sector full audit	£3,000 to £10,000+	Larger, more complex public sector websites
Large-scale multi-site audits	£12,000 to £280,000+	Councils and large organisations auditing many sites

What Actually Drives the Price

Number of pages and templates. More unique page layouts mean more manual testing time.
Complexity of interactions. Forms, checkouts, filters, and dynamic content all add testing time compared to static brochure pages.
Manual versus automated testing. Automated scans are cheap but catch only a fraction of real issues. Manual testing, especially with real assistive technology users, costs more but catches far more.
Certification level of the auditor. IAAP-certified specialists and charity-affiliated auditors typically charge more, reflecting their credibility for compliance evidence.
Whether remediation is included. Some quotes cover audit only. Others bundle audit plus fixing the issues found.

Is a Free Automated Checker Enough?

No, not on its own. Automated tools are useful for catching obvious issues quickly and cheaply, but they typically identify only a portion of real accessibility barriers. Issues like whether a screen reader announces content in a logical order, or whether a form error message is genuinely understandable, require human testing to catch reliably.

Small Business Budget Guide

For most small business websites, £600 to £2,500 covers a genuine manual audit plus a prioritised remediation plan you or your developer can work through. This roughly matches the cost of the ten-point checklist approach covered in our WCAG 2.2 checklist for UK small businesses, since a professional audit essentially verifies and expands on that starting checklist.

When the Higher-Cost Option Makes Sense

If your business needs to demonstrate compliance to an enterprise client, a public sector procurement process, or as evidence in a legal or regulatory context, a charity-grade or IAAP-certified audit at the higher end of the range provides stronger, more defensible evidence than a budget agency audit.

Ongoing Costs After the First Audit

Accessibility is not a one-time fix. Most businesses budget for:

An annual or biennial re-audit to catch regressions after site updates
Ongoing content discipline, ensuring new pages and blog posts maintain alt text, contrast, and labelling standards
A monitoring tool subscription if the site changes frequently

How Audit Cost Compares to Non-Compliance Risk

Weighed against potential Equality Act discrimination claims, reputational damage, or European Accessibility Act fines running into tens or hundreds of thousands of euros in confirmed EU cases, a £600 to £2,500 audit for a small business site is a modest proactive investment rather than a significant cost.

Frequently Asked Questions

How much does a website accessibility audit cost in the UK?
Typically £500 to £10,000 or more, with most small business sites falling in the £600 to £2,500 range.

Is a free automated accessibility checker enough?
No. Automated tools catch some issues but miss many that only manual and assistive-technology testing reveals.

What’s included in a typical accessibility audit?
Usually a combination of automated scanning, manual testing, and a prioritised report of issues found, sometimes with a remediation plan.

Why do some providers charge a fixed £4,950 regardless of site size?
Charity and government-grade providers apply a consistent, deeply credentialed testing methodology that doesn’t scale down for smaller sites.

Should I get an audit before or after fixing obvious issues myself?
Working through a basic checklist first, then getting a professional audit to verify and catch remaining issues, is often the most cost-effective order.
