The verdict in three sentences
Making a public-facing website accessible to WCAG 2.1 AA (and AODA in Ontario) costs 1,500 to 4,000 EUR for the audit in 2026, plus technical remediation (contrast, keyboard navigation, ARIA attributes, text alternatives). Remediation takes 3 to 6 weeks depending on site size and number of non-conformities. Accessibility is not just an obligation: it improves SEO, reach and institutional image while opening the site to the 15 % of the population living with a disability.
The cost of compliance in 2026
An accessibility project breaks down into audit, remediation and certification. The ranges below reflect the 2026 market for a mid-sized institutional site.
| Item | Deliverable | 2026 cost (EUR) | Timeline |
|---|---|---|---|
| Accessibility audit | Detailed WCAG report | 1,500 - 4,000 | 1 - 2 wk |
| Contrast remediation | AA-compliant palette | 400 - 1,200 | 3 - 5 d |
| Keyboard navigation | Visible focus, logical order | 600 - 1,800 | 4 - 8 d |
| ARIA + screen readers | Roles, labels, live regions | 800 - 2,500 | 5 - 10 d |
| Text alternatives | Image alt, transcripts | 300 - 1,000 | 2 - 5 d |
| Accessibility statement | Compliant page + score | 300 - 700 | 1 - 2 d |
An annual certified compliance audit (800 to 2,000 EUR) is recommended to maintain the AA level over time, since every content update can introduce regressions.
What WCAG 2.1 AA remediation fixes
The most frequent non-conformities are well known and fixing them has measurable impact on real use and on search ranking.
| Criterion | Frequent problem | Benefit after fix |
|---|---|---|
| Contrast | Illegible light grey text | Readability + SEO |
| Keyboard navigation | Menus unusable without mouse | Screen-reader use |
| ARIA attributes | Buttons not announced | Assistive understanding |
| Image alt text | Silent images | Google Images indexing |
| Heading structure | Disordered headings | Better SEO crawl |
| Forms | Fields without labels | Higher completion rate |
An accessible site is structurally better understood by search engines: the same rigour that helps a screen reader helps the crawler, delivering real SEO gains.
Mini case study
Mr. Chen, communications director of a public agency in Toronto, must make a 40-page portal compliant before an AODA review. He orders a 3,000 EUR audit that reveals 62 AA non-conformities. Remediation (contrast, keyboard, ARIA, alternatives) is quoted at 4,200 EUR over 5 weeks, plus a 500 EUR accessibility statement. Total: 7,700 EUR. The site reaches a 96 % WCAG conformance score, passes the review and gains 18 % organic traffic in three months thanks to the improved structure. The annual follow-up budget is set at 1,500 EUR.

FAQ
How much is an accessibility audit in 2026?
Between 1,500 and 4,000 EUR depending on page and template count. A mid-sized institutional portal sits around 3,000 EUR for a full WCAG audit.
What is the WCAG 2.1 AA remediation timeline?
From 3 to 6 weeks depending on the number of non-conformities. A 40-page site with around sixty issues is typically fixed in 5 weeks.
Does accessibility really improve SEO?
Yes. Clean heading structure, text alternatives and semantic code help the crawler as much as screen readers, with real organic traffic gains of 10 to 20 %.
Do we need a certified audit every year?
It is recommended. An annual follow-up audit at 800-2,000 EUR checks that content updates have not introduced regressions and maintains the AA level.
What share of the population does accessibility concern?
Around 15 % of the population lives with a disability. An accessible site therefore mechanically widens your audience and institutional reach.
