United Kingdom: Competition and Markets Authority opened consultation on revised markets regime guidance

On 20 August 2025, the Competition and Markets Authority (CMA) opened a consultation on the revised markets regime guidance updating the CMA’s approach to market reviews, studies, investigations and the monitoring and review of market remedies, until 1 October 2025. The guidance proposes a new “four Ps” framework focusing on pace, predictability, proportionality, process, use of Project Roadmaps with key performance indicators, stronger sector expertise, and earlier engagement with firms through interim reports. It clarifies powers on remedies, including default sunset clauses, closer compliance monitoring, remedy trials, and the ability to accept undertakings or vary measures at any stage, with civil penalties for breaches. The CMA seeks views on the clarity and accessibility of the guidance, the balance of speed and thoroughness in market studies and investigations, the approach to stakeholder engagement, and the proportionality of proposed remedies.
