Whistleblower law in Belgium #
Belgium implemented Directive (EU) 2019/1937 through the Act of 28 November 2022 for the private sector, alongside parallel public-sector and regional arrangements. For private companies, the main business trigger remains 50 workers, but Belgium’s structure is more fragmented than in unitary systems.
Applicable law #
Who must establish an internal channel #
Private legal entities with at least 50 workers must establish an internal reporting channel. Belgium also has public-sector and regional whistleblowing frameworks, so public bodies should check the regime that applies to their level of government.
External reporting authority #
Belgium does not operate with one single whistleblowing authority for every case. The Federal Ombudsman is a key federal external route, while sectoral and regional channels can also be relevant depending on the entity and the subject matter of the report.
Data protection authority #
For complaints about unlawful processing of whistleblower data, the relevant authority is the Belgian Data Protection Authority .
Key compliance points #
- Belgium’s whistleblowing framework is legally fragmented across private-sector, federal public-sector and regional layers, so organisations should be explicit about which regime they are following.
- The Federal Ombudsman explicitly accepts direct whistleblower reports and retaliation complaints.
- Internal policies should make clear which external authority is appropriate for the organisation’s sector and constitutional level.
