To inform the Commission about suspected infringements of the competition rules:

Complaints:

The Commission encourages citizens and firms to inform about suspected infringements of competition rules. There are two ways to do this.

If you are directly affected by the practice which you suspect restricts competition and are able to provide specific information, you may want to lodge a formal complaint, which must fulfil certain requirements. The complaint form (“Form C”) is available on the Commission Regulation (EC) No 773/2004 of 7 April 2004 relating to the conduct of proceedings by the Commission pursuant to Articles 81 and 82 of the EC Treaty. Official Journal L 123, 27.04.2004, p.18-24 (see the form on the last page “Annex”).

Information on how the Commission handles complaints is available on the Commission Notice on the handling of complaints by the Commission under Articles 81 and 82 of the EC Treaty (Official Journal C 101 , 27/04/2004 p. 65-77). A summary of this notice is available here.

The other way is the provision of market information that does not have to comply with the same requirements. You can report your concerns by e-mail to comp-market-information@ec.europa.eu. Please indicate your name and address, identify the firms and products concerned and describe the practice you have observed. This will help the Commission to detect problems in the market and be the starting point for an investigation. We invite you to read our e-services privacy policy before contacting us. You can also send your complaint by post: European Commission, Competition DG, B - 1049 Brussels.

If the situation you have encountered is specific and limited to the country or the area in which you live, or involves no more than three member States you may want to contact a national competition authority. The competition authorities of all EU Member States now apply the same competition rules as the European Commission and very often they are well placed to deal with your problem. If you think that a larger number of Member States are concerned, you may primarily chose to contact the European Commission. If you are not sure about the scope of the problem, do not hesitate to contat either the European Commission or the national competition authority because the authorities cooperate among them and will allocate the case as appropriate.
