About us

We work to promote competition for the benefit of consumers, both within and outside the UK. We have staff in London, Edinburgh, Belfast and Cardiff.

Competition that works for everyone

Competition is good for consumers and businesses. It means that people get better products at lower prices, and it helps ensure the most consumer-focused and innovative businesses are the ones that succeed.


Our responsibilities

We work to ensure that consumers get a good deal when buying goods and services, and businesses operate within the law.

We do this in a number of ways:

  • we investigate mergers between organisations, to make sure they don’t reduce competition
  • we investigate entire markets if we think there are competition or consumer problems
  • we take action against businesses and individuals that take part in cartels or anti-competitive behaviour
  • we protect consumers from unfair trading practices
  • we encourage government and other regulators to use competition effectively on behalf of consumers

The Competition and Markets Authority (CMA) is an independent non-ministerial department. Our work is overseen by a Board, and led by the Chief Executive and senior team. Decisions in some investigations are made by independent members of a CMA panel.

Our annual plan

Every year we publish our annual plan, which outlines the priorities that guide our work.

Tell us about competition problems or issues

It’s important that we hear about any problems in markets, or with specific organisations, but we can’t always respond in detail to individual complaints.

Read our guidance on how the CMA handles information and complaints for more information.

Working for the CMA

The CMA is an exciting place to work, and we have a range of roles that we recruit for.
