How to Report a Cartel
The CMA is the Competition and Markets Authority. Their priorities involve strengthening business competitiveness and preventing anti-competitive activities. Contact the CMA cartels hotline if:
- You have knowledge or concerns about a cartel.
- Your business has already been involved in a cartel.
Note: A cartel is a situation where two or more businesses agree not to compete with each other. Common types of cartels include bid rigging, market sharing, and price fixing (see below).
Under the Competition Act 1998 and the cartels policies in the United Kingdom, in some circumstances you may receive:
- Immunity from fines if you confess to, and report, a cartel you have been involved in. Read more on how to come forward and apply for leniency.
- A financial reward for the information you provide if it leads to an investigation by the CMA. Read more on CMA policy for witnessing and reporting cartels.
Note: The CMA may offer a financial reward up to £100,000 for the information received about cartel activity (in exceptional circumstances).
Reporting Other Anti-competitive Activities
You can use a form to notify the CMA about anti-competitive practices or other market issues. Use it for reporting other types of anti-competitive activity (e.g. abusing a dominant position). Fill in the form and send it by email to [email protected].
