About ACM

Mission & strategy

The Netherlands Authority for Consumers and Markets (ACM) contributes to realizing a healthy economy by ensuring that markets work well for people and businesses.

Our organization

The Netherlands Authority for Consumers and Markets (ACM) makes sure that businesses compete fairly with one another, and it protects consumer interests.


The Netherlands Authority for Consumers and Markets cooperates with other regulators and organizations that can help us carry out our duties. We cooperate with others both at a national level as well as at an international level.


ConsuWijzer is the consumer information portal of ACM. With ConsuWijzer, ACM helps consumers become well-informed and empowered. Because consumers, too, can contribute to the solution of market problems.
