Cartels & Illegal Price Fixing
Allegations of cartel behaviour, price fixing, market sharing, bid rigging or unlawful information exchange can pose serious risks to any business. With the possibility of multimillion pound fines, criminal prosecution, director disqualification and devastating reputational harm, early specialist advice is essential.
Our Competition & Regulatory Team can provide clear, strategic guidance for businesses, directors and senior employees, helping you respond quickly, protect your position and achieve the most favourable outcome.

How we help
Our lawyers act for businesses, directors, and professionals in cartel and price-fixing probes across the Competition and Markets Authority and the Serious Fraud Office.
Rapid response to investigations
We advise clients facing investigations and dawn raids by the Competition and Markets Authority (CMA) and other regulators. We can manage onsite inspections, protect legal privilege, guide staff and reduce disruption.
Defence against cartel allegations
We represent clients accused of price fixing, bid rigging, market sharing, or exchanging commercially sensitive information. We help shape the investigation, challenge evidence and work proactively to narrow or resolve allegations.
Leniency & immunity
Where appropriate, we advise on confidential leniency or immunity applications that can significantly reduce penalties or protect individuals from prosecution.
Protecting individuals
We support directors and senior managers facing personal exposure, including criminal investigation or director disqualification proceedings.
