To inform the Commission about suspected infringements of the competition rules:
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 115, 9.5.2008, p. 88–89). A summary
of this notice is available here.
: With effect from 1 December 2009, Articles 81 and 82 of the EC Treaty have become Articles 101 and 102, respectively, of the Treaty on the Functioning of the European Union ("TFEU"). The two sets of provisions are, in substance, identical. For the purposes of this Decision, references to Articles 101 and 102 of the TFEU should be understood as references to Articles 81 and 82, respectively, of the EC Treaty when where appropriate.
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
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.

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.
