Submit a Complaint to the Competition Authority
The only way we can stop anti-competitive behaviour in Ireland is to be aware that it is taking place.
If you are aware of such behaviour we would strongly encourage you to inform us. There are a number of
ways to register a complaint. The most common way is via this Make a Complaint form, but feel free to contact us:
- Via Email to: complaints@tca.ie
- Via Phone: 1890 220 224 (intl.:+353-1-8045400)
- Via Fax: +353-1-8045401
Or you can send written complaints to:
The Competition Authority,
Parnell House,
14 Parnell Square,
Dublin 1.
As a general matter, we will do everything possible not to pass on your details to any third party;
however, it is important to note that the Authority may need to divulge information that it has obtained,
including the identity of the source, to the firm under investigation. If you do choose to supply us with
your contact details, the accused party will not be made aware of your identity as the complainant without
this being discussed with you beforehand. If there is a good reason, it may be possible for us to protect
your identity; and, we would ask that you raise this concern with us at the earliest possible opportunity.
You should also be aware that there may be instances where we could be legally required to divulge your
identity and the details of the information that you provide us, e.g., in legal proceedings or under certain
provisions of the Freedom of Information Act, 1997.
If you wish, you can submit an anonymous complaint to us, but you should be aware that there is no guarantee
that the Authority will be able to take action. We can only act on such complaints if the information is
verifiable and of sufficient detail to be useful.
