UK M&A Market Trends 2026: What Buyers and Sellers Need to Know

The UK mergers and acquisitions market in 2026 is defined by cautious optimism, sector selectivity, and transformative technological change. After the volatility of recent years, the market has found firmer footing, with deal activity accelerating in key sectors whilst remaining subdued in others. Understanding these dynamics is essential for anyone planning to sell a business, make an acquisition, or advise on transactions in the current environment.

This comprehensive market analysis covers the key trends shaping UK M&A in 2026, providing actionable insights for both buyers and sellers.

The UK M&A Landscape in 2026

The UK M&A market has entered 2026 with renewed momentum following a period of adjustment. The combination of stabilising interest rates, a clearer regulatory environment post-Brexit, and significant accumulated capital seeking deployment has created conditions that are broadly favourable for transactions — particularly for high-quality businesses in attractive sectors.

However, the market is notably selective. The bifurcation that emerged in 2024-2025 — where premium businesses attracted intense buyer competition whilst lower-quality opportunities struggled — has intensified. Buyers have become more sophisticated in their assessment of business quality, and the gap between the multiples achieved by the best and worst businesses in any sector has widened considerably.

Deal Volumes and Values

UK mid-market M&A deal volumes in H1 2026 increased by approximately 15% compared to H1 2025, with total deal value rising by roughly 22%. This growth has been driven primarily by increased activity in the technology, healthcare, and professional services sectors, partially offset by continued weakness in consumer-facing and heavily leveraged businesses.

The average deal size in the mid-market has also increased, reflecting both genuine business growth and a degree of multiple expansion for quality assets. Average EBITDA multiples across all sectors have risen by approximately 0.5x compared to 2025, though with significant variation by sector and deal quality.

Notably, the proportion of deals completing successfully — the completion rate — has also improved, suggesting that buyers and sellers are aligning expectations more effectively and that deal preparation standards have risen. This is encouraging for business owners considering a sale, as it indicates a market where serious, well-prepared opportunities find willing buyers.

Sector Hotspots

Not all sectors are benefiting equally from the M&A recovery. Understanding where buyer demand is strongest helps sellers time their exit and helps buyers identify areas of opportunity.

Technology and SaaS

Technology remains the UK's most active M&A sector, with deal volumes up approximately 25% year-on-year. Within technology, SaaS businesses continue to command the highest multiples, with quality assets trading at 10-15x EBITDA (or 5-12x revenue for high-growth businesses). Cybersecurity, fintech, and AI-enabled businesses are seeing particularly strong demand.

The key theme in technology M&A is the convergence of traditional industries with technology. Businesses that successfully apply technology to transform established sectors — often called "vertical SaaS" — are attracting premium valuations because they combine the recurring revenue characteristics of technology with the stability and market knowledge of established industries.

For technology founders considering an exit, the current market offers attractive conditions, but selectivity is key. Buyers are increasingly scrutinising unit economics, customer retention metrics, and the sustainability of growth rates. Businesses with strong net revenue retention (above 110%), healthy gross margins (above 70%), and proven product-market fit are the ones achieving headline multiples.

Healthcare and Life Sciences

Healthcare and life sciences M&A continues to benefit from powerful structural tailwinds: an ageing population, increasing demand for healthcare services, and ongoing NHS capacity constraints that drive private sector growth. Deal volumes in the sector have increased by approximately 18% in H1 2026.

Particular areas of activity include primary care and dental consolidation (where buy-and-build platforms continue to acquire individual practices), specialist healthcare services (mental health, diagnostics, rehabilitation), and healthcare technology (including telemedicine, clinical decision support, and patient management systems).

Multiples in healthcare remain robust at 8-12x EBITDA for quality businesses, reflecting the sector's defensive characteristics and growth visibility. However, regulatory risk and workforce challenges continue to feature prominently in buyer due diligence.

Professional and Business Services

The professional services sector has seen a significant uptick in M&A activity, driven by consolidation among accounting firms, engineering consultancies, recruitment businesses, and marketing agencies. Deal volumes are up approximately 20% year-on-year, with private equity particularly active in the sector.

The attraction of professional services businesses lies in their recurring revenue characteristics, relatively low capital requirements, and scalability through geographic expansion or service line extension. Businesses with strong client retention, diversified revenue bases, and capable management teams are commanding multiples of 6-9x EBITDA.

For professional services firm owners, the current market represents an attractive window. The combination of strong PE interest, multiple expansion, and sector consolidation is creating competitive dynamics that benefit sellers. Our team at VAMOS has particular experience in this sector and can advise on timing and positioning.

Private Equity Activity

Private equity remains one of the most significant forces in UK mid-market M&A, and its influence in 2026 is stronger than ever.

Dry Powder and Deployment Strategies

UK-focused PE firms entered 2026 with record levels of uninvested capital — estimated at over £80 billion. With fund lifecycles creating pressure to deploy this capital, PE firms are actively seeking quality acquisition opportunities across all sectors.

However, PE firms have become more disciplined in their deployment strategies. The days of paying premium prices based on aggressive growth assumptions have given way to a more measured approach that emphasises earnings quality, defensibility, and downside protection. PE buyers are increasingly focused on businesses with strong cash flow generation, proven business models, and identifiable value creation levers.

For sellers, this means that PE buyers are serious, well-capitalised, and willing to pay fair prices for quality businesses — but they won't overpay for businesses that don't meet their investment criteria. Professional preparation and positioning are essential to attract PE interest and achieve competitive pricing.

Buy-and-Build Strategies

Buy-and-build — where PE firms acquire a platform business and then make additional acquisitions to build scale — continues to be one of the most popular PE strategies in the UK mid-market. This approach is particularly prevalent in fragmented sectors such as healthcare, professional services, and business services.

For business owners in these sectors, buy-and-build creates opportunities as both platform acquisitions (typically larger businesses that serve as the foundation for further acquisitions) and bolt-on acquisitions (smaller businesses that are added to an existing platform). Platform acquisitions generally command higher multiples but come with greater expectations around management capability and growth potential.

Cross-Border M&A

Cross-border transactions continue to play a significant role in UK M&A, with overseas buyers accounting for approximately 40% of total deal value in H1 2026.

Inbound Investment into the UK

The UK remains an attractive destination for international acquirers, despite ongoing geopolitical uncertainties. The combination of English common law, a skilled workforce, the English language, and London's status as a global financial centre continues to draw buyers from North America, Europe, and increasingly from Asia and the Middle East.

US buyers have been particularly active in 2026, attracted by the relative value of UK assets (which often trade at a discount to US equivalents) and the opportunity to establish or expand a European presence. European strategic buyers remain active, seeking UK businesses that complement their existing operations or provide access to the UK market.

For UK sellers, international buyer interest creates competitive tension that can drive up prices. However, cross-border transactions introduce additional complexity around regulatory approvals, cultural differences, and practical logistics. Experienced M&A advisers with international networks are essential for managing these complexities effectively.

Interest Rates and Acquisition Financing

The interest rate environment is one of the most important macro factors influencing M&A activity and valuations. After the rapid increases of 2022-2023, the Bank of England has gradually reduced rates through 2024-2025, with the base rate settling at levels that are higher than the ultra-low era but significantly below recent peaks.

Impact on Valuations

Stabilising interest rates have had a positive effect on M&A valuations by reducing the cost of acquisition financing and improving buyer confidence. Lower debt service costs mean that buyers can afford to pay more for the same level of cash flow, supporting higher EBITDA multiples.

However, the relationship between interest rates and valuations is nuanced. While lower rates generally support higher multiples, the effect is moderated by other factors including buyer competition, sector dynamics, and the quality of individual businesses. In the current market, the primary driver of valuation differences is business quality rather than financing conditions.

For both buyers and sellers, the current interest rate environment creates a relatively favourable window for transactions. Buyers can access financing at reasonable rates, whilst sellers benefit from the valuation support that affordable financing provides. This equilibrium may not last indefinitely, adding urgency for those considering a transaction in the near term.

AI Disruption and Its Impact on M&A

Artificial intelligence is transforming the M&A landscape in two distinct ways: as a factor in business valuation and as a tool in the deal execution process itself.

AI as a Value Driver

Businesses that have successfully integrated AI into their operations or products are commanding premium valuations. AI capabilities signal scalability, efficiency, and future-readiness — all attributes that buyers value highly. Companies using AI for customer service automation, predictive analytics, process optimisation, or product enhancement are seeing tangible impacts on their multiples.

Conversely, businesses in sectors vulnerable to AI disruption face valuation headwinds. Buyers are increasingly asking how AI might affect a target's competitive position, workforce requirements, and revenue model over the medium to long term. Businesses that cannot articulate a clear AI strategy risk being perceived as technological laggards.

For business owners, the message is clear: understanding and, where appropriate, integrating AI is no longer optional. Even in traditional sectors, demonstrating awareness of AI opportunities and having a roadmap for adoption can positively influence buyer perceptions and support higher valuations.

AI in Deal Execution

AI is also revolutionising the M&A process itself. AI-powered tools are being used for due diligence document analysis (dramatically reducing the time required to review thousands of contracts), buyer identification (using predictive models to identify the most likely and highest-value acquirers), valuation analysis (benchmarking against larger datasets of comparable transactions), and risk assessment (identifying patterns and anomalies that human analysts might miss).

These tools are making the M&A process faster, more thorough, and more cost-effective. Advisers who leverage AI effectively can deliver better outcomes for their clients by covering more ground in less time and identifying insights that might otherwise be overlooked.

H2 2026 Outlook

Looking ahead to the second half of 2026, we expect the positive trends from H1 to continue and potentially accelerate. Several factors support this outlook: continued PE deployment pressure, a stable regulatory environment, improving business confidence, and the ongoing digital transformation driving strategic acquisitions.

What This Means for Sellers

For business owners considering a sale, the current market represents one of the most favourable windows in recent years. Buyer demand is strong, financing is available, and multiples have recovered to attractive levels — particularly for quality businesses in the sectors highlighted above.

However, market conditions can shift quickly, and the current window won't remain open indefinitely. Geopolitical risks, potential economic slowdown, or changes in fiscal policy could all impact buyer sentiment. For owners who are ready or nearly ready, there's a strong argument for acting sooner rather than later.

The key is preparation. In a selective market, well-prepared businesses attract premium interest whilst unprepared ones struggle. Invest the time in getting your financials right, reducing owner dependency, and building a compelling investment case. The return on this investment will be measured in the multiple you achieve.

What This Means for Buyers

For acquirers, the market presents both opportunity and challenge. Opportunities exist in sectors where deal activity has been slower to recover, in businesses where owners are motivated by personal circumstances, and in situations where proprietary deal sourcing can avoid competitive auction processes.

The challenge is that quality businesses in attractive sectors are well-priced, and competitive tension among buyers is driving multiples upward. Buyers who can differentiate themselves — through sector expertise, operational improvement capabilities, or speed and certainty of execution — will have the greatest success in winning deals at reasonable prices.

For registered buyers, our programme provides early access to professionally prepared opportunities, helping you identify and secure the right acquisition before it reaches the broader market.
