The verdict in three sentences
Since accessibility obligations expanded, a mid-cap with turnover above 50M EUR must bring its website into line with WCAG 2.1 level AA or face administrative sanctions. The audit costs 2,000 to 6,000 EUR and remediation 4,000 to 15,000 EUR depending on site size. Building accessibility in from the design phase rather than as a fix cuts the bill by 30 to 50% and mechanically improves SEO and user experience.
Who is concerned and what are the 2026 obligations
Accessibility is no longer reserved for the public sector. The European Accessibility Act and its national transpositions extend obligations to the private sector. Here is the 2026 landscape.
| Organisation type | 2026 obligation | Potential sanction | Statement required |
|---|---|---|---|
| Public sector | WCAG 2.1 AA mandatory | Up to 50,000 EUR | Yes + multi-year plan |
| Mid-cap > 250 emp. / >50M EUR | WCAG 2.1 AA mandatory | Up to 50,000 EUR | Yes |
| Consumer e-commerce | WCAG 2.1 AA (EAA) | Fine + withdrawal | Yes |
| SME < 50M EUR turnover | Recommended (not mandatory) | None direct | No |
| Bank / insurance | Reinforced AA | High | Yes + annual audit |
The accessibility statement and multi-year plan must be published on the site: their absence is the first thing checked during an inspection.
The cost of accessibility compliance in 2026
The budget depends heavily on when accessibility is addressed: upstream (design) or downstream (fixing an existing site).
| Item | Remediation (existing site) | From the design phase |
|---|---|---|
| WCAG 2.1 AA audit | 2,000 - 6,000 EUR | Included in scoping |
| Technical fixes | 4,000 - 15,000 EUR | +10 to 20% of dev |
| Accessibility statement | 500 - 1,500 EUR | Included |
| Editorial team training | 800 - 2,500 EUR | Included |
| Annual control audit | 1,500 - 4,000 EUR/year | 1,500 - 4,000 EUR/year |
| First-year total | 8,800 - 29,000 EUR | 4,500 - 14,000 EUR |
The gap is clear: anticipating accessibility nearly halves the cost, because there is no code rework or rebuilding of non-accessible components.

Mini case study
Catherine, general secretary of a 410-employee services mid-cap in London (turnover 68M EUR), discovers she now falls under accessibility obligations. Her 40-page institutional site undergoes an audit (4,500 EUR) revealing a 42% compliance rate. Remediation costs 11,000 EUR and takes 6 weeks. Unexpected bonus: organic traffic rises 18% in 4 months thanks to semantic structure and performance improvements. The 15,500 EUR investment partly turns into measurable SEO leverage.
FAQ
Is my company really obligated? If you exceed 250 employees and 50M EUR turnover, or operate in a regulated sector (banking, consumer e-commerce), yes. Below that it is strongly recommended but not directly sanctionable in 2026.
What exactly is WCAG 2.1 AA? It is the international accessibility standard covering contrast, keyboard navigation, text alternatives, structure and screen-reader compatibility. Level AA is the legal reference and includes dozens of testable criteria.
Does accessibility improve SEO? Yes, strongly. Semantic structure, alt text, heading hierarchy and performance are criteria shared by accessibility and search ranking. An accessible site is almost always better indexed.
How long does remediation take? Allow 4 to 10 weeks depending on site size. A 10-page brochure site is fixed in 3 weeks; a 50-page institutional site needs 8 to 10 weeks.
Is the accessibility statement mandatory? Yes for subject organisations. It must state the compliance rate, non-accessible content and a contact. Its absence is the easiest non-compliance to establish during an inspection.
