The verdict in three sentences
A non-accessible institutional site excludes 15-20% of the population and now exposes the company to financial penalties. WCAG 2.1 level AA compliance requires an audit, fixes and a published accessibility statement. It's better to budget 3,000-8,000 EUR for the audit and 5,000-20,000 EUR for remediation than to risk a fine up to 50,000 EUR and reputational damage.
What accessibility rules require in practice
The standard breaks WCAG 2.1 AA into verifiable criteria. An institutional site must satisfy every family of criteria to be declared compliant.
| WCAG 2.1 AA area | Requirement | Common non-conformity |
|---|---|---|
| Perceivable | Text alternatives, contrast | Images without alt, contrast < 4.5:1 |
| Operable | Keyboard navigation, visible focus | Menus not keyboard-accessible |
| Understandable | Labeled forms, clear errors | Fields without labels, silent errors |
| Robust | Compatible with assistive tech | JS components without ARIA markup |
| Statement | Publish the conformance rate | No statement online |
On an average corporate site, an initial audit often reveals a conformance rate of 45-60%, well below the legal threshold.
Cost of compliance vs cost of risk
The decision isn't "should we" but "how fast." Here are the 2026 ranges.
| Item | Budget 2026 | Timeline | Note |
|---|---|---|---|
| WCAG 2.1 AA audit | 3,000-8,000 EUR | 2-3 wks | Depends on page count |
| Remediation | 5,000-20,000 EUR | 6-12 wks | Depends on initial gap |
| Accessibility statement | Included | 1 wk | Legal obligation |
| Potential penalty | up to 50,000 EUR | — | In case of breach |
| Annual upkeep | 1,500-4,000 EUR/yr | Ongoing | Monitoring changes |
The total remediation cost stays below a single penalty, not counting the gains in audience and search ranking.

Mini case study
Karen, communications director at a large firm in New York (80-page corporate site, high media visibility). A review flags a conformance rate of 52% and no statement. She orders a 6,500 EUR audit then 14,000 EUR remediation: contrast fixes, form labeling, ARIA markup, keyboard navigation. In 10 weeks the rate rises to 96% and the statement is published. Side benefit: organic traffic grows 12% thanks to better semantic markup, and the company secures the public tenders that require compliance.
FAQ
Which companies are covered in 2026? Large enterprises, public bodies and, increasingly, private actors under the European accessibility directive and equivalent regulations. The scope widens every year.
What must the accessibility statement contain? The measured conformance rate, the list of non-conformities, any exemptions and a means of recourse. It must be reachable from every page.
How long does remediation take? From 6 to 12 weeks depending on the initial gap and site size. Contrast and labeling fixes are quick; ARIA markup of complex components takes longer.
Does accessibility help SEO? Yes: clean semantic markup, text alternatives and a clear structure also improve Google's understanding, with traffic gains of 10-15%.
Should the audit be redone every year? An annual check is recommended because each new page or feature can introduce regressions. Budget 1,500-4,000 EUR/year for upkeep.
