Why accessibility overlays don't protect you from the EAA

EAA Comply · Updated July 2026 · 6 min read

If you run an online shop in the EU, someone has probably offered you a one-line fix for the European Accessibility Act: paste a snippet, a widget appears, your site is "compliant". It costs €50–100 a month and it takes five minutes.

It also doesn't work. Not "works imperfectly" — it fails at the one job you're paying for: keeping you legally safe. Here's the evidence.

The track record: fined vendors and sued customers

Why a widget can't fix your code

The EAA (Directive (EU) 2019/882) points to the EN 301 549 standard, which points to WCAG. Those requirements live in your HTML: form fields need real labels, buttons need accessible names, checkout flows must work with a keyboard, images need meaningful alternatives, contrast must be built into the design.

An overlay is JavaScript injected on top of broken code. It can change font sizes and colours cosmetically, but it cannot reliably rewrite your DOM, relabel your forms, fix your focus order or repair your checkout. Screen reader users usually disable overlays because the widget fights the assistive technology they already use.

Side-by-side comparison: a webpage with a cosmetic overlay patch slapped over a broken form and a still-visible crack, versus the same webpage with the underlying HTML actually fixed, labeled, and checked off. Overlay widget <button aria-label="Add"> <label for="qty">Qty</label> </button> Fixed code
An overlay sits on top of broken markup and the crack still shows through; fixing the actual HTML — labels, semantics, keyboard flow — is what closes it for good.

The test that settles it: unplug your mouse and try to complete a purchase on your site using only the keyboard. An overlay doesn't change the result. Fixing the code does.

What the EAA actually requires

Since 28 June 2025, most businesses selling products or services to EU consumers (micro-enterprises excepted) must make their e-commerce accessible and publish an accessibility statement. Member state market surveillance authorities can require corrective action and impose penalties — Spain's framework allows fines up to six figures for serious cases, and enforcement activity is growing across the EU.

Compliance means three concrete things: your site actually conforms to WCAG 2.1 AA in its code, you publish an honest accessibility statement, and you keep both true as the site evolves.

What to do instead (and what it costs)

Real compliance is not more expensive than the fake kind — it's just front-loaded. And unlike a widget, it ends: once your code is fixed, you own the result.
