Competition Act and cartels

Here you can find information on the Competition Act and how to comply with the law. You can also find out what constitutes a cartel and how a business could be granted immunity from fines and individuals avoid prosecution (through the OFT's leniency programme) if they inform the OFT of their involvement in anti-competitive activity.

This section also provides information about Competition Act related investigations, decisions, consultations and case closure summaries (where cases are in the public domain).

Leniency

There are severe penalties for individuals and businesses that engage in cartels - and every incentive for those individuals and businesses to stop such practices and tell the OFT about the cartel.

Confess your cartel to the OFT
