Current Status: Implemented
Expected or actual implementation date or timeline
19 Jan 2026 (entry into force of the Law of 19 December 2025 on the resilience of critical entities).
If implemented, whether a transition period applies and, if so, its duration
Applicable since publication date, but certain provisions phase in, including sanctions. By 17 July 2026, sectoral authorities will designate critical entities within their respective sectors. Entities designated as operators of European or national critical infrastructure under the previous Act of 1 July 2011 on the security and protection of critical infrastructure (repealed by the CER Act) shall, as of 17 July 2026, be deemed by operation of law to be critical entities as referred to in Article 11 of this CER Act.

Transposition deadline of the CER Directive was 17 October 2024, so Belgium’s transposition was completed too late.
