Updates to the CMA’s mergers procedural guidelines (CMA2 and CMA56)

The CMA is consulting on proposed updates to its published guidance relating to its procedures in operating the merger control regime as set out in the Enterprise Act 2002.

Last fetched 03 May 2026 · gov.uk
Detail

These documents have been updated in preparation for the end of the Transition Period following the UK’s departure from the European Union. The proposed updates also reflect a series of changes in UK merger control over recent years, as the CMA’s practice has developed and the UK Courts have clarified various aspects of the framework.

The updated guidance aims to streamline the CMA’s processes, increase investigative efficiency, and emphasise the importance of cooperation and coordination with international competition agencies following the end of the Transition Period.

Responses to the consultation document should be provided to MergersProceduralGuidance@cma.gov.uk by no later than 5pm on 4 December 2020.
