I received a letter from the ACM about accessibility, what should I do?

An ACM letter is the start of a remediation process, not a fine

A letter from ACM about accessibility is usually the start of a remediation process and not yet a fine. ACM writes to companies that do not appear to meet the requirements of EN 301 549 — in practice WCAG 2.1 level AA — and sets a remediation period of approximately three months. Only after that period follows a retest, and only if that retest again reveals deficiencies does sanctioning come into view.

For those who receive such a letter, this means there is room to remedy the mentioned deficiencies and to record this in an improvement plan. By mid-2026, ACM has not yet imposed formal fines; however, there have been public notices where an improvement plan was required. Reporting yourself to ACM that a company does not yet comply, with a plan of action, results in lenient treatment — but that route belongs to the moment before a notice arrives. Once the letter is there, what matters is how convincing and timely the response to the notice is, not whether it was reported voluntarily. For those wondering whether the company falls under this at all: micro-enterprises offering services, with fewer than ten employees and at most two million euros in annual turnover, are exempt — a scope check will confirm that. An automated scan can never determine that a site is fully compliant, by the way; it shows some of the deficiencies, not full compliance.

What ACM itself publishes about this

This follows from ACM's publication on the supervision of website and app accessibility, in which the supervisory authority describes its own approach: issuing notices, granting a remediation period, retesting, and only then sanctioning. That same source states that by mid-2026 there have been public notices with required improvement plans, but no formal fines yet.
