Website accessibility used to be treated as a nice-to-have. It no longer is — ADA-related website lawsuits in the USA number in the thousands annually, and both the UK and EU have their own enforceable frameworks. This is general information, not legal advice; consult a qualified lawyer in your jurisdiction for anything contract or liability related. It pairs with the technical steps in our web accessibility implementation guide.
Why This Has Become a Real Legal Risk, Not Just Best Practice
Courts in the USA have increasingly treated websites as "places of public accommodation" under the ADA, meaning an inaccessible website can trigger the same legal exposure as an inaccessible physical store. The UK and EU have taken a more explicit regulatory route, writing digital accessibility requirements directly into law rather than relying on court interpretation of older legislation.
USA: The Americans with Disabilities Act (ADA)
The ADA itself predates the modern web and doesn't explicitly mention websites, but US courts have consistently applied it to commercial websites, generally using the WCAG 2.1 Level AA standard as the practical benchmark plaintiffs and courts reference. Businesses of any size with a public-facing website can be targeted, though larger consumer-facing brands and eCommerce stores see the most lawsuit activity.
UK: The Equality Act 2010
The UK's Equality Act requires "reasonable adjustments" for disabled users, which has been interpreted to extend to digital services including websites. Public sector websites additionally fall under the more specific Public Sector Bodies Accessibility Regulations, which explicitly reference WCAG 2.1 AA compliance and require a published accessibility statement.
EU: The European Accessibility Act (EAA)
The EAA came into full effect in June 2025 and applies directly to a defined set of private-sector digital services and products sold in the EU, including eCommerce. Unlike the more court-driven US approach, the EAA is a explicit statutory requirement with defined enforcement mechanisms per member state — meaning EU-facing businesses have a clearer, codified compliance bar to meet rather than relying on case-law interpretation.
| USA (ADA) | UK (Equality Act) | EU (EAA) | |
|---|---|---|---|
| Legal basis | Court interpretation of existing law | "Reasonable adjustments" duty | Explicit statute (2025) |
| Practical standard | WCAG 2.1 AA (de facto) | WCAG 2.1 AA (public sector explicit) | WCAG 2.1 AA (referenced standard) |
| Enforcement | Private lawsuits, DOJ guidance | Tribunal claims | Per-member-state regulators |
Regardless of which region's law applies to you, building to WCAG 2.1 Level AA covers the practical requirements of all three frameworks simultaneously — there's no need to build separate compliance efforts per region.
What All Three Actually Require in Practice
Across all three frameworks, the common practical requirements are: sufficient color contrast, full keyboard navigability, proper alt text on images, correctly labelled form fields, and content that works with screen readers. None of these require a website redesign from scratch — they are targeted, addressable fixes on an existing site.
Conclusion: Whether your primary market is the USA, UK, or EU, website accessibility has moved from "good practice" to a defined legal expectation with real enforcement behind it. Building to WCAG 2.1 AA is the practical way to meet all three frameworks at once, and it's genuinely achievable without an enterprise-scale project.
AppsBrain builds every website to WCAG 2.1 AA standards by default and offers accessibility audits for businesses that need to bring an existing site into compliance across US, UK, or EU markets.
