Rules for digital markets competition regime levy

Overview

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

The Digital Markets, Competition and Consumers Act 2024 gives the CMA powers to charge a levy to firms designated with Strategic Market Status (SMS).

The final levy rules set out the methodology for the calculation and apportionment of the levy among SMS firms.

The CMA consulted on the proposed approach to a levy for the digital markets competition regime between 5 June 2025 and 3 July 2025, and has now published its response to the consultation and its final levy rules.
