Competition and Markets Authority

United Kingdom government non-ministerial department

The Competition and Markets Authority (CMA) is the principal competition regulator in the United Kingdom. It is a non-ministerial government department in the United Kingdom, responsible for promoting competitive markets and tackling unfair behaviour. The CMA launched in shadow form on 1 October 2013 and began operating fully on 1 April 2014, when it assumed many of the functions of the previously existing Competition Commission and Office of Fair Trading, which were abolished. The CMA also has consumer protection responsibilities and took on new digital markets regulation responsibilities in late 2024 under the Digital Markets, Competition and Consumers Act 2024.
