CMA updates social media platform guidance to reflect Digital Markets, Competition and Consumers Act 2024 requirements
The Competition and Markets Authority (CMA) has updated its guidance for social media platforms on reviews and endorsements to align with the Digital Markets, Competition and Consumers Act 2024 (DMCCA 2024). Published on 28 August 2025, the revised guidance reflects new statutory obligations under paragraph 13 of Schedule 20 to the DMCCA 2024, requiring platforms to prevent and remove fake reviews and concealed incentivised content. The update maintains the original six compliance principles while incorporating the CMA's enhanced enforcement powers under the DMCCA 2024, including the ability to issue direct fines and directions to those breaking consumer protection law. The guidance applies to all social media platforms operating in the UK across desktop, mobile and app-based formats.
