The Competition and Markets Authority (CMA) has published Working Paper 7 (WP7) which sets out the appropriate type of remedies that may be available where an adverse effect on competition is identified during its market investigation into the supply of mobile browsers and mobile browser engines, and the distribution of cloud gaming services through app stores on mobile devices. This follows the CMA’s announcement in June 2022 to investigate Apple and Google’s market power in mobile browsers and Apple's restrictions on cloud gaming through the Apple App Store. WP7 sets out the evidence that the CMA has gathered during the investigation to date and sets out the framework for the assessment and selection of remedies, alongside any potential issues relating to the remedies. WP7 should be read alongside the previous six working papers published during the investigation. The CMA has also published Verian’s final report on its research on UK smartphone users which sought to understand consumer behaviour in the mobile browser market, with a particular focus on the role of preinstallation and the drivers of browser choice on smartphone devices. Verian Group UK, which was appointed by the CMA to conduct the research as part of its investigation, sets out a summary of the main findings of its quantitative and qualitative research.

The Competition and Markets Authority (CMA) has published a Remedies Working Paper seeking views on the effectiveness of a proposed remedy package for the Vodafone/Three merger proposal. This package would alleviate the CMA's concerns after it provisionally found in September 2024 that the merger could lead to higher prices for customers and harm the position of mobile virtual network operators (MVNOs). In the paper, the CMA provisionally finds that a legally binding commitment to undertake the network integration and investment programme proposed by the two companies would significantly improve the quality of the merged company’s mobile network, boosting competition between mobile network operators in the long term and benefiting customers. The CMA also found that short-term protection would be needed to ensure that retail consumers and MVNOs can continue to secure good deals during the initial years of network integration and investment roll-out. The CMA consultation on the paper runs until 5 pm on 12 November 2024.

The Competition and Markets Authority (CMA) has published its decision made on 19 July 2024 to clear the proposed acquisition by Roche Diagnostics Limited of point-of-care testing technology held by London-based LumiraDx Group Ltd and LumiraDx International Ltd, both of which are in administration. Lumira offers multiple point-of-care tests on one portable device and offers Roche a wide range of immunoassay and clinical chemistry tests. Roche intends to add the point-of-care testing system to its diagnostics portfolio. The deal was announced on 29 December 2023 and the CMA announced its merger inquiry on 23 May 2024.

The Competition and Markets Authority (CMA) has reviewed methods in which grocery retailers display their prices in-store to assess whether they were clear, accurate and matched the price people were charged at the till. After on-site inspections of 139 grocery stores, the most common types of issues seen were missing prices, conflicting prices and prices not being displayed sufficiently close to products. The CMA and Trading Standards (TS) have published compliance materials as a result of these findings, aiming to aid grocery retailers comprehension on what they need to do to comply with the law.

The Competition and Markets Authority (CMA) has published its response to the consultation on draft consumer law compliance advice for businesses marketing green heating and insulation products, which it launched in December 2023. The consultation followed concerns of potentially misleading claims about green heating and insulation products and the provision of limited and inconsistent price information. The response sets out stakeholders' main comments and the CMA's response to them, as well as the corresponding changes it has made to the final advice. Amendments made by the CMA include clarification that the draft covers solar PV panels, and that the advice applies to marketing practices on any marketing channel, including verbal claims made in person or over the phone. The CMA has now published its final compliance advice. Alongside the compliance advice, the CMA has also published some short videos and checklists for businesses summarising the principles which are designed to help them comply with the law.

The Competition and Markets Authority (CMA) has published a summary of responses to its consultation on the draft annual plan 2026–27 and released the final annual plan. The consultation, which ran from 21 January 2026 to 18 February 2026, received 21 written submissions and engaged over 60 organisations through various forums, including the CMA's Growth and Investment Council and Consumer Forum. The annual plan is the first detailed implementation plan under the CMA's new 2026–29 strategy. This strategy aims to drive economic growth and improve household prosperity through five core objectives: (1) promoting effective competition; (2) championing consumers; (3) aiding government in deploying tailored pro-competition interventions; (4) fostering a UK regulatory landscape that attracts investment and (5) prioritising UK interests. The plan incorporates the CMA's 4Ps framework—focusing on pace, predictability, proportionality and process.

The Competition and Markets Authority (CMA) has published new compliance guidance for unregulated providers of Will-writing, online divorce and pre-paid probate services, alongside an open letter it sent to seven providers of such services cautioning them against using practices such as aggressive upselling, the refusal of refunds, and failing to respond to complaints. This follows an investigation into potential breaches by unregulated providers of these legal services, which opened in July 2023, and a consultation on the compliance guidance which ran between April and June 2024. Guides for customers have also been published by the CMA for people making a Will or going through a divorce, with information about what they should keep in mind when purchasing these services. The guidance provides information on the key requirements of consumer laws which businesses must comply with, and sets out practical steps and case study examples.

The Competition and Markets Authority (CMA) has published a corporate report from its Microeconomics Unit analysing supply chains and market power in the UK. It establishes a framework for: (1) measuring and understanding the ever-evolving nature of UK supply chains; (2) documenting where market power sits across the supply network; (3) placing UK supply chains in a global context and (4) assessing how external shocks flow through supply chain networks. The report forms part of the Unit’s ongoing growth programme, which supports the government’s growth agenda by delivering research on key drivers and constraints of economic growth.

The Competition and Markets Authority (CMA) has published correspondence with the Department for Energy Security and Net Zero, in which the Secretary of State asked the CMA to consider carrying out a review of competition in the home heating market. The Secretary of State noted the importance of the home heating market to the country’s net zero ambitions and requested the review to understand whether any weaknesses in competition are contributing to prices being higher than they would in a well-functioning market, as the sector transitions to low-carbon heating. The CMA acknowledged the Secretary of State’s concerns and committed to considering such a review in the second half of 2024, noting the CMA’s large portfolio of existing work, but continued to state that any output from the CMA would likely include recommendations back to government to address issues that may be identified.

The Competition and Markets Authority (CMA) has published a discussion paper setting out how price transparency (PT) schemes, enabled by the Data (Use and Access) Act 2025 (DUAA), could support consumer confidence and effective competition in UK markets. PT schemes are described as a subset of smart data schemes that rely on business data such as pricing and product information, shared by businesses with aggregators and made available to Authorised Third Parties (ATPs). The paper highlights the planned Fuel Finder scheme, expected to be operational by the end of 2025, which is estimated to deliver consumer savings of £10.1bn over a ten-year appraisal period.
