CMA meaning

What does CMA mean?
In practice, CMA refers to the UK’s competition and markets authority, the national competition regulator that investigates mergers, cartels and abuse of dominance and enforces consumer protection law. The body is created and named by statute (Enterprise and Regulatory Reform Act 2013) and exercises powers principally under the Competition Act 1998 and the Enterprise Act 2002, now complemented by the Digital Markets, Competition and Consumers Act 2024. Key functions include UK merger control (Phase 1/Phase 2), market studies and market investigations, antitrust enforcement with administrative fines, acceptance of commitments and remedies, criminal cartel enforcement, director disqualification, and consumer law enforcement. It can conduct dawn raids, operate a leniency programme, issue guidance and works with concurrent sector regulators. Decisions are generally reviewable by the Competition Appeal Tribunal. Jurisdiction is UK‑wide (England & Wales, Scotland and Northern Ireland). The CMA has no competence in Ireland; the nearest equivalent there is the Competition and Consumer Protection Commission (CCPC). Usage of “CMA” is therefore consistent across UK practice and is not used to describe Irish regulators. Practitioners use “CMA” in the context of UK competition law, merger notifications, market investigations, digital markets regulation and consumer enforcement.

CMA draft pricing guidance: delivery charges and the DMCC total price requirement across product listings, baskets and checkouts (UK)

Overriding principles The DMCC’s core requirement is that a product’s “total price” must be shown prominently in every invitation to purchase (ITP). (For what constitutes an ITP, see here.) The total price covers all amounts the consumer will inevitably pay, which therefore includes any compulsory delivery charges. There is a limited DMCC exception. Where, owing to the nature of the product, a compulsory delivery charge cannot reasonably be worked out in advance, every ITP must explain how that charge will be calculated. This explanation must appear with the same prominence as the total price and must enable the consumer to determine the overall cost. Typically, equal prominence means placing this information beside or immediately below the total price. Before relying on this carve‑out, traders should be satisfied that the compulsory delivery charge genuinely cannot be calculated beforehand. The CMA has indicated that the exception will be applied narrowly...

UK Digital Markets, Competition and Consumers Act 2024 and EU Digital Markets Act compared: scope, designation, obligations, compliance and enforcement for core platform services and strategic market status

Background This Practice Note presents a concise overview of the main themes for comparing the UK and EU approaches to competition in digital markets. Specifically, it examines the regulatory regimes created by the Digital Markets, Competition and Consumers Act 2024 (DMCCA 2024) and Regulation (EU) 2022/1925 on contestable and fair markets in the digital sector, which amends Directive (EU) 2019/1937 and Directive (EU) 2020/1828, the EU Digital Markets Act (EU DMA). What’s happening in the UK? Online platforms and digital advertising have faced intense regulatory attention across the UK, the EU and further afield, including the USA and Australia. Although digital markets can yield major gains for consumers and for wider economies, that scrutiny revealed weakened rivalry stemming from a small cohort of powerful digital businesses active in the market. In the UK, this led to demands for tougher enforcement powers and pre-emptory tools to permit quicker action. That process culminated in the DMCCA 2024, Part 1 of which introduces new regulatory functions granted to the Competition...

UK criminal and regulatory dawn raids: practitioner FAQs on search warrants, privilege, seizures, digital searches and staff interviews

1 What is a dawn raid? A dawn raid refers to an unannounced attendance by the police or investigators from another prosecuting authority to search premises where they suspect a business or individual has been involved in criminal conduct. Teams commonly arrive first thing in the morning (hence the term ‘dawn’), with the surprise element intended to secure, protect and preserve evidence. Methods are often robust and forceful, meaning the organisation must respond rapidly and appropriately to satisfy its obligations and minimise interference with the day‑to‑day operation of the business. 2 Where do the investigators come from? In the UK, a range of authorities have powers to carry out dawn raids. These may include, but are not limited to: Information Commissioner’s Office (ICO) the police Financial Conduct Authority (FCA) Serious Fraud Office (SFO) HM Revenue & Customs (HMRC) Competition and Markets Authority (CMA) Health and Safety Executive (HSE) 3 What are the chances of a...
