The Competition and Markets Authority's (CMA) purpose is to help people, businesses and the UK economy by protecting competition and tackling unfair behaviour.


Consultation outcome

We consulted on draft new markets regime guidance to reflect changes resulting from the Digital Markets, Competition and Consumers Act 2024 (DMCCA) and changes in other legislation since the Enterprise and Regulatory Reform Act 2013, to reflect developments in CMA practice over time, and to simplify the suite of markets regime guidance documents.

This consultation was open for responses from 5 November 2024 to 3 December 2024.

Following this consultation, in August 2025 we launched another consultation on further amendments to the market regime guidance.
