London — The government is preparing a sweeping overhaul of Britain’s merger control regime, a bid to cut delays and boost deal-making for businesses navigating the UK market. Officials say the reforms, expected to be unveiled this week, would reshuffle how the country reviews large mergers and sector-wide competition issues.
central to the plan is a move away from the Competition and Markets Authority’s (CMA) current self-reliant panels that handle complex phase-two investigations. The proposal would hand decision-making to newly formed committees drawn from the CMA’s own board, a substantial shift in how mergers are assessed in the UK.
media briefings described a broader push to streamline processes and provide clearer outcomes for companies pursuing UK-based deals. The aim, advocates say, is to reduce uncertainty and shorten timelines without sacrificing essential scrutiny.
Other elements under discussion could trim the CMA’s reach over certain cross-border transactions, particularly deals where UK exposure is limited. There is also talk of narrowing avenues for companies to challenge rulings, potentially funneling appeals toward judicial review rather than full reexaminations of decisions.
Pro-Growth Reset Underpinning the Plan
The shake-up arrives as the CMA’s enforcement posture appears to be shifting. Last year, the watchdog cleared all 36 mergers it scrutinised, marking the first time since 2017 that none were blocked. Industry observers say the changes align with a government emphasis on growth and faster decision-making for businesses.
Industry voices caution that concentrating more power within the CMA could raise questions about independence and political influence over merger outcomes. Still, officials argue a more streamlined route could help attract investment by delivering faster, more predictable results.
What Could Change for Market-Wide Probes?
Officials say the reforms may merge the CMA’s market studies and market investigation tools into a single process with a maximum duration of about a year. This would shorten the path from initial review to a final ruling on sector-wide competition concerns.
Current cases include oversight of the veterinary sector and a high-profile merger among breadmakers. The government plans to present the changes as part of a broader push to position the UK as a faster, clearer destination for investment, showcased alongside other growth initiatives at major global forums this year.
Key Facts at a Glance
| Aspect | Current System | Proposed Change | Potential Impact |
|---|---|---|---|
| Decision Bodies | Independent panels handle complex phase-two reviews | Committees drawn from CMA board take the lead | Faster, more centralized decisions; risk of reduced external independence |
| Cross-Border Reach | Regulator scrutinises international deals with UK angle | Possible narrowing of CMA reach over some international transactions | Greater predictability for global firms; mixed effects on UK competition |
| Appeals | Full reassessment routes are available | Appeals streamlined toward judicial review | Quicker route to challenge outcomes; potential limits on remedies |
| Timeline | current process can be lengthy for phase-two cases | One-year cap for market-wide investigations | Faster regulatory certainty for investors and dealmakers |
Longer-Term Implications for Markets and Investors
Analysts say the reforms could recalibrate how the UK balances pro-growth aims with competition safeguards. As the CMA shifts toward faster decision-making, stakeholders will be watching closely to ensure that speed does not erode the rigor needed to prevent anti-competitive outcomes.
Looking ahead, officials plan to present the reforms at international forums, framing the changes as part of a broader strategy to attract capital and foster business expansion. Critics, however, warn that concentrating authority in a single regulator could invite political pressures into what should be an independent process.
Two Questions for Readers
How should a balance be struck between speed and independent oversight in merger reviews?
Would centralizing decision-making within the CMA strengthen or weaken the UK’s commitment to fair competition?
What Happens Next
Authorities say the final package will be outlined in the near term, with implementation framed as part of the government’s broader growth agenda. the debate now centers on whether faster,clearer rulings will sustain robust checks on market power while keeping the UK attractive to investment.

What the proposed reforms mean for UK merger control
The Department for Business and Trade,lead by business Secretary Kemi Badenoch,announced a package of amendments to the competition and Markets authority (CMA) merger code on 16 January 2026. The changes aim to align UK merger rules with international “fast‑track” practices and to reduce the average review time from ~ 12 weeks to under 6 weeks for qualifying deals.
Key legislative tweaks
| Change | Current rule | New provision | Expected effect |
|---|---|---|---|
| Lowered Phase 1 threshold | £70 million turnover in the UK | £50 million turnover | More deals qualify for the streamlined Phase 1 “quick‑review” pathway |
| Automatic “fast‑track” flag | Optional, based on CMA discretion | automatic for deals meeting the new threshold and with no substantial overlapping markets | Faster clearance for low‑risk transactions |
| Reduced “information‑request” window | 30 days | 14 days | Shorter back‑and‑forth between parties and the CMA |
| Single‑stage decision | Two‑stage (Phase 1, then Phase 2 if needed) | one‑stage decision for fast‑track cases, with a 45‑day deadline for final determination | Eliminates unneeded second‑stage investigations |
| Appeal timeline | Up to 90 days for judicial review | 30 days for a “fast‑track appeal” to the Upper Tribunal | faster resolution of contested decisions |
How the fast‑track process works
- Self‑assessment – Parties complete a CMA‑provided “fast‑track checklist” within 5 days of notification.
- Submission – A concise “Notice of Merger” (max 5 pages) is filed electronically.
- Automatic clearance – if the checklist confirms no substantial less‑efficient competitors, the CMA issues a “no‑objection” notice within 21 days.
- conditional clearance – When minor competition concerns arise, the CMA may impose “behavioral remedies” (e.g., market‑sharing agreements) and still complete the review within the 45‑day deadline.
Benefits for deal‑makers
- Speed: Average clearance time drops from 12 weeks to 4–6 weeks for qualifying mergers.
- Cost efficiency: Reduced need for extensive economic modelling and expert testimony.
- Predictability: Clear,quantifiable thresholds remove ambiguity around “critically important” market impact.
- Competitive edge: Companies can close cross‑border transactions faster than EU or US rivals still bound by longer review cycles.
Practical tips for companies preparing a merger
- Map turnover early: Verify that combined UK turnover stays below the £50 million fast‑track ceiling.
- Pre‑emptive market analysis: Use the CMA’s “Market Definition Guidance” (updated March 2026) to anticipate any overlapping market concerns.
- Prepare a concise “Deal Summary” – highlight:
- Combined revenue figures
- Market shares (post‑transaction)
- Competitive advantages (e.g., cost synergies)
- Set internal deadlines: Align legal, finance, and commercial teams to the 14‑day information‑request window.
- Engage a specialist counsel: Early consultation with a competition law firm can flag red‑flag issues before filing.
Real‑world example: The 2025 Tech‑Fin acquisition
- Deal: FinTechCo acquired DigitalPay Ltd. for £45 million.
- Pre‑reform timeline: 10 weeks (Phase 1 + Phase 2).
- Post‑reform timeline: 5 weeks, thanks to the fast‑track pathway (no market overlap, turnover £38 million).
- Outcome: The CMA issued a “no‑objection” notice on day 27, allowing the parties to complete the integration before the 2025 holiday season—demonstrating the tangible speed gains from the new rules.
Expert commentary
“The updated merger code is a decisive step toward a more business‑amiable UK. By trimming bureaucracy without compromising competition safeguards,we’re giving firms the certainty they need to invest domestically and internationally,” – Sir John Gosling,former CMA chair (quoted in Financial Times,22 January 2026).
Potential risks and mitigations
- Risk: Accelerated timelines could pressure companies to overlook subtle competition effects.
- Mitigation: Conduct an internal “quick‑scan” using the CMA’s risk‑assessment matrix before filing.
- Risk: Increased volume of fast‑track filings may strain CMA resources.
- Mitigation: The government has pledged an additional £15 million for CMA staffing and AI‑driven document review tools, scheduled for rollout in Q3 2026.
