How to Hire an Accessibility Consultant: Costs and Red Flags

You know your website needs work. Maybe a demand letter arrived, maybe a customer complained, maybe you read about the European Accessibility Act and realised your business might be in scope. You have decided to bring in an expert — and immediately hit the real problem: every firm in the search results promises you the same thing, in almost the same words.

The gap behind those identical promises is the expensive part. A good consultant drives your site by hand with a keyboard and a screen reader and hands back a short prioritised list your developer can start on Monday. A bad one runs the same free scanner you could have run yourself, exports two hundred pages of raw output, and invoices you four figures for it. Both get called “an audit,” both arrive as a PDF, and only one of them tells you anything a machine could not. Telling them apart before you sign is most of what this guide is for.

Below: what a consultant actually does, the red flags worth walking away from, what engagements cost, and the questions to ask on the first call. (Nothing here is legal advice.)

Why You Might Need an Accessibility Consultant

Not every business needs to hire a consultant. If your website is a simple five-page brochure site built on WordPress or Squarespace, you can probably handle most accessibility fixes yourself with the right guides.

But you should consider hiring a consultant if:

  • You received a legal demand letter or lawsuit. You will want documented evidence of what you found and what you fixed, with dates. We cannot tell you what weight any given document carries in a negotiation or a courtroom — that is a question for your lawyer, and it varies by jurisdiction and by posture. What is clear is that a dated audit and remediation record is the thing you cannot produce retroactively. See what to do in the first 48 hours, and, before you budget, how much an ADA website lawsuit costs.
  • Your site is complex. Custom web applications, e-commerce platforms with hundreds of product pages, or sites with interactive tools like configurators and calculators benefit from expert review.
  • You need to comply with a regulation quickly. The European Accessibility Act, ADA, Section 508, or AODA all have specific technical requirements. A consultant can prioritize the highest-risk issues and create a realistic remediation timeline.
  • Your team lacks accessibility expertise. If no one on your team knows what WCAG 2.2 means or how to test with a screen reader, a consultant can bridge that knowledge gap.
  • You want to build accessibility into your process. A good consultant does not just fix today’s problems. They train your team to avoid creating new barriers.

What Does an Accessibility Consultant Actually Do?

A typical accessibility engagement includes some or all of these activities:

Audit and assessment. The consultant reviews your website against WCAG 2.2 Level AA success criteria using a combination of automated tools and manual testing. Manual testing is the part you are actually paying for. Published estimates of how much an automated scanner catches vary widely by tool and by page, and we would rather not quote a single percentage as though it were settled — but every figure we have seen leaves the majority of WCAG failures undetected, and the costly ones (keyboard traps, broken focus management, alt text that is present but meaningless) sit squarely in the part no scanner can judge. A thorough audit includes testing with screen readers, keyboard-only navigation, and various assistive technologies.

Prioritized remediation plan. Rather than dumping a list of 500 issues on your desk, a good consultant organizes findings by severity and business impact. Critical issues that block users from completing core tasks (purchasing, logging in, submitting forms) come first.

Remediation support. Some consultants fix the issues themselves. Others work alongside your development team, providing guidance on how to implement fixes correctly. Both models work, but make sure you understand which one you are paying for.

Training. The most valuable part of many engagements is training your content editors, designers, and developers to avoid creating new accessibility barriers. This is what turns a one-time fix into lasting compliance.

Accessibility statement and policy. A consultant can help you draft an accessibility statement for your website and an internal accessibility policy for your organization.

Ongoing monitoring. Some consultants offer retainer arrangements that include periodic re-audits, review of new content and features, and monitoring for regressions.

What to Look for in a Consultant

Technical Credentials

Look for consultants who hold recognized accessibility certifications:

  • IAAP CPAC (Certified Professional in Accessibility Core Competencies) — demonstrates broad knowledge of accessibility principles, standards, and laws.
  • IAAP CPACC or WAS (Web Accessibility Specialist) — the WAS certification specifically covers web accessibility testing and remediation.
  • DHS Trusted Tester certification — particularly relevant if your business works with U.S. government agencies.

Certifications are not everything, but they indicate a baseline of verified knowledge. Be cautious of consultants who cannot articulate which standards they test against or who rely solely on automated scanning tools.

Manual Testing Experience

Ask how the consultant tests. The right answer includes:

  • Screen reader testing (NVDA, JAWS, VoiceOver) across multiple browsers
  • Keyboard-only navigation testing
  • Testing at various zoom levels and text sizes
  • Testing with voice recognition software like Dragon NaturallySpeaking
  • Color contrast analysis using tools like the Colour Contrast Analyser
  • Automated scanning as a supplement, not a replacement, for manual testing

If a consultant tells you their audit is entirely automated, that is a red flag. Automated tools miss the majority of accessibility barriers, especially issues related to reading order, meaningful alternative text, keyboard focus management, and logical heading structure. See why a 95 Lighthouse score is not a defence for what that gap looks like on a real page.

Communication Skills

A consultant who speaks exclusively in WCAG success criterion numbers is not helpful to a business owner who needs to understand the business impact. Look for someone who can:

  • Explain issues in plain language
  • Connect accessibility failures to real user experiences
  • Provide clear, actionable remediation steps your team can follow
  • Adjust their communication style depending on whether they are talking to executives, designers, or developers

Industry Experience

While web accessibility principles are universal, different industries face different challenges. An e-commerce consultant will be familiar with product filter accessibility, checkout flow testing, and cart update announcements. A healthcare consultant will understand patient portal requirements and HIPAA intersection with accessibility. Ask for case studies or references from businesses similar to yours.

Red Flags to Watch For

”We’ll make you 100% compliant”

No responsible consultant guarantees 100 percent compliance. Accessibility is an ongoing practice, not a checkbox. Websites change constantly — new content, new features, new third-party integrations. Anyone promising perfection is either exaggerating or does not understand accessibility deeply enough.

Overlay solutions as the primary recommendation

If a consultant’s primary recommendation is to install an accessibility overlay or widget — the JavaScript products that promise to remediate your site from a single embedded script — treat that as disqualifying. Overlays do not make a website conform to WCAG, they sometimes introduce new barriers of their own, and installing one has not stopped sites from receiving demand letters. Accessibility practitioners and disability advocacy groups have argued against them publicly and at length. A credible consultant will recommend fixing the underlying code, not adding a layer on top of it. We go through the mechanics in why accessibility overlays don’t work.

No manual testing

An audit that consists entirely of automated scan results is not worth paying for. You can run WAVE or axe DevTools yourself for free. The value of a consultant is their ability to identify issues that machines cannot detect.

Vague deliverables

If the proposal does not clearly describe what you will receive — number of pages tested, testing methodology, format of the report, remediation guidance detail level — ask for clarification before signing.

No mention of assistive technology users

A consultant who never mentions real users with disabilities, never references screen reader behavior, and treats accessibility purely as a compliance checkbox is missing the point. The goal is to make your site usable by real people, not just to pass an automated scan.

How Much Does It Cost?

Accessibility consulting costs vary widely based on the scope of work, the size and complexity of your website, and the consultant’s experience level. The figures below are prevailing market rates for consulting engagements, not our own; for a wider breakdown of what accessibility work costs, see how much website accessibility costs.

Initial audit: For a small to medium website (under 50 unique page templates), expect to pay between $3,000 and $15,000 for a thorough manual audit with a detailed remediation report. Large enterprise sites can cost $25,000 or more.

Remediation: If the consultant is doing the fix work, costs depend on the number and severity of issues. Budget $5,000 to $30,000 for a typical small to medium site remediation. Complex web applications can be significantly more.

Training: Half-day workshops typically cost $2,000 to $5,000. Multi-day programs for development teams can be $5,000 to $15,000.

Retainer and monitoring: Ongoing monthly retainers range from $1,000 to $5,000 per month depending on the level of support.

Be wary of prices that seem too good to be true. A $500 accessibility audit for a 100-page website is almost certainly an automated scan with a logo slapped on it.

Questions to Ask Before Hiring

Use these questions during your initial conversations. If you are hiring a web designer or agency rather than a specialist auditor, the parallel list in questions to ask your web designer about accessibility covers the same ground for a build engagement.

  1. What standards do you test against? (Answer should include WCAG 2.2 Level AA at minimum)
  2. What is your testing methodology? (Should include both automated and manual testing with assistive technologies)
  3. How many pages or templates will you test? (Should be clearly defined in the proposal)
  4. What will the deliverable look like? (Ask for a sample report)
  5. Do you provide remediation support or just a report? (Know what you are paying for)
  6. What assistive technologies do you test with? (Expect to hear specific screen readers, keyboards, and tools)
  7. What is your position on accessibility overlays? (A credible consultant will advise against them)
  8. Can you provide references from similar businesses? (Look for relevant industry experience)
  9. Do you offer training for our team? (Long-term value comes from building internal capability)
  10. How do you handle retesting after remediation? (Make sure fixes are verified)

What a Good Engagement Looks Like

A well-run accessibility consulting engagement typically follows this pattern:

Week 1-2: Discovery and scoping. The consultant reviews your site, identifies the most important user flows, and defines the testing scope. They may ask about your content management system, development process, and any known issues.

Week 3-5: Audit and testing. The consultant conducts thorough manual and automated testing across the agreed scope. They test with multiple screen readers, keyboard-only navigation, and other assistive technologies.

Week 6: Report delivery. You receive a detailed report with issues organized by severity, screenshots or screen recordings demonstrating each barrier, the relevant WCAG criterion, and clear remediation steps. The best reports include code examples showing the current markup and the corrected version.

Week 7-8: Walkthrough and Q&A. The consultant walks your team through the findings, answers questions, and helps prioritize remediation based on your resources and timeline.

Ongoing: Remediation support. As your team fixes issues, the consultant is available to review fixes, answer questions, and retest resolved items.

Follow-up: Retest. After remediation, the consultant retests to verify fixes and identify any regressions or new issues introduced during the fix process.

Starting with What You Can Do Today

While you search for the right consultant, there are steps you can take immediately. Run a free automated scan using browser extensions like axe DevTools or WAVE. Check your site’s keyboard navigation by putting your mouse aside and pressing Tab through your pages. These quick checks will give you a sense of the scope of work and help you have more informed conversations with potential consultants.
