UK competition law enforcement: a multi-regulator perspective

1 min read

On this page

Across every regulated sector, scrutiny of regulators is intensifying. 

Competition enforcement in the UK is shared between the CMA and several concurrent regulators, with powers to investigate and enforce competition law within their respective sectors, operating alongside the CMA. The second edition of CMS’s Competition Enforcement Report presents the research and analysis of enforcement activity of the CMA and seven concurrent regulators since 2000, giving you a complete data-driven view of the competition enforcement landscape.

Across all the concurrent sectors, we see a trend of regulators resorting to their wider toolkit to address competition-related issues, such as regulatory levers, warning or advisory letters or carrying out initial investigatory steps before deciding whether to formally deploy their competition powers.

Now you have the full picture.
