Make a Complaint

The Competition Commission (Commission) relies on complaints and queries from the public as an important means of identifying possible contraventions of the Competition Ordinance (Ordinance). The Commission will accept complaints in any form, including those provided to the Commission:

(a) directly;
(b) anonymously; and
(c) through an intermediary (such as a legal adviser).

A complaint or query may be made by telephone, e-mail, post, by completing an online form on the Commission’s website or in person at the Commission’s office (by appointment only). A complaint may be submitted on behalf of more than one person or party.

Where the Complainant has provided relevant contact details, the Commission will usually acknowledge receipt of the complaint promptly.

Before making a complaint, you may wish to visit the "Report Anti-Competitive Conduct” Information Centre to learn more about the red flags of anti-competitive conduct and some common queries when filing a complaint.

For further information on the processes the Commission will use for determining what action to take in relation to a complaint, please refer to the Guideline on Complaints.

Anonymity and Confidentiality

The Commission accepts complaints provided anonymously.

Section 125 of the Ordinance imposes a general obligation on the Commission to preserve the confidentiality of any confidential information provided to or obtained by the Commission, including information that relates to the identity of any person who has given information to the Commission.

The Commission will not normally disclose the Complainant’s identity, without the Complainant’s consent. In some exceptional cases however, it may be necessary to disclose the Complainant’s identity without their consent. This includes where disclosure is ordered by the courts or under section 126(1)(b) of the Ordinance where the Commission considers it necessary to make a disclosure in the performance of its functions or in carrying into effect or doing anything authorised by the Ordinance.
