Understanding the Competition and Markets Authority

The Competition and Markets Authority acts as a watchdog. It investigates unfair business practices, prevents anti-competitive mergers, and takes action against businesses that break consumer protection law. While the CMA focuses on large-scale market issues, they rely on reports from the public to identify where Competition and Markets Authority support UK is most needed.

Common Situations People Face

• Price-Fixing (Cartels): Noticing that all local competitors have raised prices to the exact same level simultaneously.

3. Anonymity: You can request to remain anonymous, especially when reporting an employer.
