CMA Enforcement Priorities 

Businesses are entering another pivotal year for UK competition law. The Competition and Markets Authority (CMA) will continue to exercise enhanced powers under the Digital Markets, Competition and Consumers Act 2024 (DMCCA), alongside updated merger control thresholds and a sharper enforcement strategy.

The last year has seen significant change for the CMA’s agenda, with there being a sea-change at the executive level and an increased focus on growth and being ‘business friendly’. The Government announced the ‘strategic steer’ for the CMA in May 2025, calling on the CMA to use its regulatory powers to encourage competition, with the hope of it leading to more innovation, choice, quality, security of supply, productivity, investment, and economic dynamism.

In tandem, the CMA released its ‘4Ps’ framework (pace, proportionality, predictability and process), highlighting an updated approach to reviewing digital mergers and firms under the DMCCA. These changes mean businesses in the UK need to be alive to the CMA’s priorities and take proactive action to anticipate any CMA interest in their M&A activity.

Looking to 2026 and beyond, the CMA’s 2026–2029 strategy and enforcement priorities signal an assertive and targeted enforcement approach. Specifically, the three-year strategy will focus on the following objectives:

Promoting effective competition

  • Implementation of the 4Ps framework across all operations
  • Ensuring competition enforcement and merger control foster dynamic markets and innovation
  • Focus on the implementation of the digital markets regime and Strategic Market Status (SMS) designations to unlock growth and choice

Championing consumers

  • Enhanced consumer protection through new powers to order redress and sanction non-compliance, in particular focusing on issues of ‘drip pricing’, misleading discounts, false urgency practices such as ‘countdown timers’ and fake reviews
  • New controls on subscription contracts
  • Updated guidance for businesses on unfair terms to aid compliance with consumer law
  • Potential reforms to the secondary ticketing market

Helping government deploy pro-competition interventions

  • Advice on public procurement and regulatory barriers
  • Supporting the removal of anti-competitive regulations and enabling access to critical data
  • Provision of independent advice on subsidies and the UK internal market

Fostering a UK regulatory landscape that attracts investment

  • Creation of a predictable, proportionate environment to boost investor confidence
  • Alignment with broader regulatory reforms and embedding the 4Ps approach

Prioritising UK interests

  • Focus on markets and issues with the greatest impact on UK citizens and businesses
  • Supporting strategically significant sectors and avoiding unnecessary duplication of global efforts

More broadly, the CMA will be considering the following aspects.

Digital markets oversight

The CMA will focus on firms with significant influence over digital ecosystems, particularly those designated with SMS (to date, both Apple and Google have been designated as having SMS by the CMA). Expect proactive investigations into conduct that restricts competition, such as self-preferencing, tying, and exploitative data practices. 

Businesses that rely heavily on this online digital infrastructure should consider whether any anti-competitive practices by these SMS entities impact their ability to compete. If so, there may be better recourse to remedies post-DMCCA implementation. 

Consumer protection integration

Enforcement will increasingly combine competition and consumer law, addressing practices that distort choice or mislead consumers. The CMA intends to use its new powers under the DMCCA to impose direct orders and financial penalties without court involvement. Most recently in November 2025, the CMA launched a number of investigations into firms which it believes may have breached consumer law protections, demonstrating the CMA’s intent to follow through on its enforcement promises. 

Merger scrutiny

The CMA will prioritise mergers in sectors where innovation is critical, such as technology and life sciences. Transactions that risk eliminating nascent competitors will face heightened review, even where they may fall below traditional turnover thresholds. The CMA will rigorously review sectors which have a clear impact on the UK’s growth to ensure innovation continues to thrive. 

The Government is also anticipated to introduce legislative reform proposals to provide more certainty on where mergers will be subject to investigation in the UK by addressing uncertainty with the existing ’share of supply’ test (which grants the CMA jurisdiction to review a transaction where merging parties hold a combined share of 25% or more) and the ‘material influence’ test (which enables the CMA to potentially review acquisitions of minority stakes). The CMA has historically applied both tests with considerable flexibility, often resulting in broad assertions of jurisdiction and more uncertainty for merging parties. The anticipated reforms are intended to support the Government’s objective of ensuring that the CMA’s decisions are, as promised, more “predictable and proportionate” for businesses and investors.

International cooperation

Cross-border enforcement will remain a priority, with the CMA strengthening ties with EU and global regulators to tackle multi-jurisdictional anti-competitive conduct.

Implications for businesses and next steps

Implications for businesses and next steps

The CMA remains vigilant in its merger control assessments. While there is an increased focus on pace and predictability, meaning hopefully more efficient and consistent reviews, the CMA will continue to interrogate mergers closely in areas of strategic priority. If you are looking at acquiring businesses, consider early and proactive engagement with the CMA. 

Businesses operating in digital markets or sectors with significant consumer impact should expect closer monitoring and heightened scrutiny. The CMA’s ability to impose direct orders and fines without court involvement under the DMCCA means enforcement will be faster and more disruptive.

The CMA has also highlighted in its three-year strategy that effective competition does not preclude legitimate business collaboration, which can support investment, innovation and growth. If you believe there may be an opportunity to legitimately cooperate with a competitor, leading to tangible economic benefit and growth for consumers, get in touch and we can assist with reviewing any such agreements.

Reforms to National Security and Investment Act 2021

In 2025, the Government launched a consultation on significant amendments to the National Security and Investment Act 2021 (NSIA), marking the first major update since the regime came into force in January 2022. These changes aim to ensure that the mandatory notification framework remains proportionate, targeted, and responsive to evolving national security risks while reducing unnecessary burdens on businesses. The consultation closed in October 2025 and we await the formal changes to be announced by the Government.

The NSIA currently requires mandatory notification for acquisitions in 17 sensitive sectors, including defence, energy, communications, and advanced materials. While the regime is generally viewed as effective (with most transactions being cleared at the initial review phase), feedback from stakeholders and recent annual reports indicate that certain aspects of the framework could be streamlined to improve clarity and efficiency.

Key proposed amendments

  • Creation of new standalone sectors
    • Semiconductors: previously grouped under ’advanced materials’, it is proposed that semiconductors become a distinct category, incorporating computing hardware activities. This reflects their critical role in defence, AI, and modern infrastructure
    • Critical minerals: a new schedule will cover extraction, processing, and recycling of minerals essential to national resilience. The list will expand to include additional rare earth elements, aligning with the UK’s latest criticality assessments
    • Water sector: for the first time, water infrastructure and services may fall within the mandatory regime, recognising their importance to national security and resilience
  • Refinements to existing definitions
    • Artificial Intelligence: the scope may narrow to focus on entities developing AI systems or conducting safety and capability testing, excluding routine internal uses of off-the-shelf AI
    • Data infrastructure: may be broadened to include third-party-operated data centres and certain cloud service providers
    • Critical suppliers to government: may be updated to reflect a wider range of public authorities and subcontractors supporting emergency services
  • Exemptions for low-risk transactions
    • Mandatory filings: may no longer be required for intra-group reorganisations or the appointment of insolvency practitioners (for example, liquidators or special administrators), reducing compliance burdens for businesses engaged in restructuring or distressed transactions
Implications for businesses

Implications for businesses

These reforms aim to sharpen the focus of the NSIA regime on genuinely high-risk transactions, freeing resources within the Investment Security Unit to concentrate on deals with a clear national security nexus. However, the inclusion of new sectors such as water and critical minerals will broaden the scope of mandatory filings, requiring businesses in these areas to reassess their compliance strategies when considering acquisitions. 

The consultation closed on 14 October 2025, and legislative changes will follow. Companies operating in or adjacent to the affected sectors should review the proposals carefully and consider conducting internal reviews to assess whether the changes may affect any proposed acquisition or sale processes.

CMA Market Investigation into Veterinary Services for Household Pets

The CMA launched its market investigation into the supply of veterinary services for household pets in May 2024, following concerns raised during an earlier market review. This review formally opened on 7 September 2023, with the aim of assessing whether the market was working well for consumers and identifying any competition issues and the final report is due by May 2026. The market investigation was prompted by evidence of rising costs for pet care and complaints about transparency and choice in the sector. In line with the CMA’s priorities, the CMA appeared to be keen to investigate a sector which has a direct impact on consumers' everyday spending abilities. 

Procedure and key steps

The CMA’s investigation into veterinary services follows a formal process under the Enterprise Act 2002. It was launched after an initial market review raised concerns about rising costs and limited consumer choice, prompting a full market investigation.

Following the reference, the CMA gathered evidence from veterinary businesses, consumer groups, and regulators through information requests, site visits, and hearings. An Issues Statement was published to outline the scope and invite stakeholder responses.

In early 2025, the CMA issued working papers highlighting concerns around pricing transparency, ownership disclosure, barriers to switching, and regulatory adequacy. These were subject to public consultation.

On 15 October 2025, the CMA published its Provisional Decision Report, summarising findings and proposed remedies. A consultation ran until 14 November, followed by response hearings in November and December.

The CMA is now reviewing feedback and refining remedies. The final report is expected by March 2026, ahead of the statutory deadline of 22 May 2026, and will confirm any binding orders and regulatory reform recommendations.

Provisional findings

The CMA’s provisional findings indicate that the veterinary services market for household pets is not functioning effectively for consumers. The investigation identified several significant concerns:

  • Transparency and information gaps
    The CMA found that pet owners often lack clear and timely information about the ownership of veterinary practices, pricing structures, and available treatment options. Many practices are part of large corporate groups, but this is not always disclosed to consumers, limiting their ability to make informed choices. Pricing transparency was also highlighted as a major issue, with costs for routine and emergency treatments varying widely and often not provided upfront.
  • Barriers to consumer choice and switching
    The CMA concluded that consumers face practical and informational barriers when trying to compare services or switch providers. For example, there is no standardised approach to publishing prices, and some practices restrict access to medical records, making it harder for pet owners to move to a different provider. These factors reduce competitive pressure and may lead to higher prices.
  • Regulatory shortcomings
    The current regulatory framework was deemed outdated and insufficient to address modern market realities. While individual veterinary professionals are regulated, there is no comprehensive regime governing corporate ownership or business practices. This gap means that some consumer protection issues—such as complaints handling and transparency obligations—are not adequately enforced.

Proposed remedies

To address these concerns, the CMA has proposed a package of measures, including:

  • Legally binding transparency requirements: a CMA Order would require veterinary businesses to provide clear information on pricing, ownership, and available services
  • Mandatory complaints handling: practices would need to implement formal complaints procedures and offer mediation options
  • End-of-life care transparency: clear disclosure of costs and options for cremation and related services
  • Regulatory reform: recommendations to Government for a new statutory regime covering veterinary businesses and professional conduct
Next steps

Next steps

The CMA is currently reviewing responses to its provisional findings and proposed remedies. Response hearings took place during December 2025, after which the CMA will finalise its analysis. The final report is expected by March 2026, with the statutory deadline for completion set at 22 May 2026. If the CMA confirms its provisional conclusions, significant changes to transparency obligations and regulatory oversight will follow. You can view the CMA’s case page here
