Competition lawyers

Competition law risk is increasingly a board level issue. All businesses need to focus on its impact on their activities.

Mergers require strategic thought up front, as to structuring and substantive competition risk. Pricing and distribution strategies need to be attuned to potential allegations of dominance. Cartel risk needs to be identified and assessed quickly, but accurately. Practical, and sometimes innovative, solutions need to be found in a fast-moving commercial context.

Our team of competition lawyers has extensive experience in helping to navigate these difficult paths so that clients can keep their focus on their business. We have in-depth knowledge of how the competition rules apply in practice across different markets. Our sector focus helps us understand your business environment and get to grips with your issues.

We can help you devise your business strategies to address these challenges and take advantage of the opportunities they offer. We also have hands-on experience of dealing with the competition authorities and courts, and we work with our CMS network of specialist competition lawyers across the EU and beyond. We're experienced in acting on high-profile competition and dawn raid investigations before the UK and EU competition authorities, and we also deal with sector regulators including ORR, Ofgem, and Ofcom. We regularly advise on day-to-day competition issues including commercial agreements and practices, compliance programmes and provide competition law training and audits.

The CMS Competition Practice Group has more than 150 competition lawyers, making it one of the largest competition teams within Europe. Our experts provide you with tailor-made advice on competition issues at both the European Union (EU) and national levels. The competition lawyers spread across the CMS offices are supported by the CMS EU Law Office in Brussels.
