Submitting your tip-off or indication to ACM

Is a firm not playing by the rules? Are, for example, your competitors concluding agreements regarding prices or customers? If so, please let us know. You can do this anonymously as well. Your tip-off can help us track down violations.

Consumers may contact ConsuWijzer

You are considered a consumer if you purchased a product or a service, and this product or service is not used for your job or profession. Consumers may contact the Netherlands Authority for Consumers and Markets for free information and advice from our consumer information desk ConsuWijzer. Please note that, while you may submit your tip-off or indication to us in English, we can only give you advice in Dutch.

For example, you have a problem with a company. You could inform consumer information desk ConsuWijzer thereof, and ConsuWijzer will then advise you on how to solve your problem. ConsuWijzer’s advice informs you of your rights and how you can exercise them. If it turns out that, based on your complaint, the company in question violates the law, we can take action.

Businesses may contact ACM

Businesses may contact the Netherlands Authority for Consumers and Markets for any indications they might have of other firms that do no stick to the rules, for example, because they have concluded price-fixing agreements. Have you purchased a product or service that is used for your job or profession? Then you are not considered a consumer. In that case, too, are you able to file a complaint with ACM. Your complaint must concern fields or topics that falls under ACM’s oversight.

If it turns out that, based on your complaint, the company in question violates the law, we can take action.

Please again note that, while you may submit your tip-off or indication to us in English, we can only give you advice in Dutch.

Do you have a legal problem, dispute or disagreement with another firm or with a consumer? And the two of you are unable to reach a solution? You may then require specialist legal help.

In that case, you may submit your tip-off anonymously to our special intelligence unit. Our intelligence unit is specially trained to deal with your anonymity in a proper manner.
