Backdrop for UK M&A in 2026

After several years of volatility, the UK M&A market enters 2026 with a mix of cautious optimism and renewed selectivity. Deal volumes are still below the post-pandemic peak, but 2025 saw UK M&A deal value in sterling more than double versus 2024 on UK Office for National Statistics (ONS) figures, driven by mega deals, larger average transaction sizes and strong inbound demand.

Market Tone: Resiliency and High Interest from Foreign Acquirers

Following a solid rebound in 2024, 2025 UK M&A volumes edged down slightly but remained historically healthy, while total deal value in £ rose sharply as more large-cap and inbound transactions completed. Higher financing costs, geopolitical uncertainty and shifting tax expectations led some owners to delay processes, while buyers became more forensic on earnings quality and downside protection, lengthening deal timetables and increasing the use of structured consideration.

The market is remaining resilient. Well-run SMEs with strong cash conversion, recurring revenues and defensible niches have continued to transact at robust multiples, especially where there is a clear strategic fit for trade or buy-and-build platforms.

The ONS data charts below show how overall UK deal volumes have normalised from the 2021 peak, even as the share and value of inbound foreign acquisitions have increased meaningfully since 2024.

In this environment, foreign acquirers are playing an increasingly prominent role in the UK M&A landscape. ONS data show that in 2025, overseas buyers accounted for around 57% of completed UK deals by volume (foreign acquirers versus domestic) and a striking 87% of total UK M&A deal value, reflecting the impact of larger inbound transactions. Overseas strategics and financial sponsors are attracted by structural sterling weakness versus prior years, the depth of UK management talent, and the opportunity to acquire market-leading SMEs at valuations that still look attractive in their home currencies.

Macro and Geopolitics – Uncertainty Remains

Monetary policy is still central to M&A sentiment. The Bank of England base rate peaked at 5.25% in 2023–2024 and, by early 2026, has only begun to edge down, leaving real borrowing costs materially higher than in the 2010s. At the same time, wars in Ukraine and the recent escalation in the Middle East, including conflict involving Iran, have pushed up energy prices and kept inflation risks in focus, tempering expectations of rapid rate cuts and reminding both buyers and sellers that the macro picture remains fragile.

Gradual normalisation in inflation and expectations for modest rate cuts are improving visibility on funding costs, even if debt remains more expensive than in the pre-2022 era. This is allowing well-capitalised trade and financial buyers to underwrite deals with more confidence, while still being disciplined on leverage levels.

At the same time, inflation has moderated and the tax environment feels more predictable than it did in 2023–2024, reducing one of the key reasons many owners deferred exit decisions. This greater visibility is encouraging founders to revisit succession, de-risking and partial realisation options they had previously parked.

Plenty of Capital – Strategics are Acquisitive and Private Funds Have $4.5 Trillion of Dry Powder

For shareholders, the key practical point is less "who" in the abstract and more how the equity story is framed for each buyer group – synergy-driven industrial logic on one side, roll-up and value-creation levers on the other – at a time when global private equity dry powder is still estimated at around $2–2.5 trillion and broader private capital funds hold more than $4.5 trillion of undeployed capital, creating intense competition for high-quality assets.

Recent announced UK transactions in 2025 across software, technology, healthcare, industrial services and specialist manufacturing illustrate this mix of buyers.

A Selective, Quality-First Market

If there is one defining characteristic of the current SME deal environment, it is selectivity. Several themes stand out:

• Evidence over narrative: Buyers are insisting on evidence, not just narrative: KPIs around recurring revenue, customer concentration, churn, margin resilience and cash generation.
• Due diligence: Increased scrutiny on technology, compliance, ESG, cybersecurity, management, resilience to economic cycles & geopolitical shocks.
• Valuations: Cyclical or weak performers face multiple compression or struggle to transact at all, while businesses combining growth with strong margins command higher valuation multiples.
• Structure: Earn-outs, vendor loan notes and other structured mechanisms are being used more frequently to bridge valuation gaps and share risk, particularly where earnings are volatile or heavily adjusted.

For sellers, this means that preparation and positioning are no longer optional. The businesses that win competitive tension are those that can present clean numbers, a credible growth story and a clear role for the acquirer.

Sector Pockets of Strength

Beyond the usual focus on technology and business services in private markets, listed sector data tell a more nuanced story. Over the past three years, global technology indices still screen as the strongest compound performers, but industrials and construction and building materials have also delivered robust, relatively steady gains, while business services, healthcare, food and beverage and chemicals have largely moved sideways or lagged. In other words, the market has been rewarding industrial and manufacturing names with resilient growth and cash generation more consistently than broad.

The most recent data into Q1 2026 add another layer: energy and basic materials – including chemicals – have staged a sharp rebound from a depressed base as the Iran conflict and wider Middle East chokepoints push oil and gas prices and shipping costs higher, lifting sector indices and producer equities. By contrast, global tech has traded more sideways this year after a powerful run-up, while industrials and manufacturing businesses have continued to grind higher, reflecting investor preference for tangible earnings, pricing power and supply-chain resilience rather than pure multiple expansion.

What This Means for SME Owners

For UK SME shareholders, the message in 2026 is nuanced but encouraging. The market is not racing back to the froth of 2021–2022, and significant macro and geopolitical uncertainty remains, but conditions are constructive for well-prepared sellers. Several practical implications follow:

1. Timing

For many owners, the next 12–24 months are a sensible window to prepare and, where appropriate, test the market while valuations for high-quality assets remain robust and buyer appetite is supported by large pools of undeployed capital, even against a backdrop of ongoing uncertainty.

2. Preparation

Value is being won or lost long before you "go to market". Robust management information, a clear growth plan and early diligence on issues like contracts, IP, tax and HR can materially improve outcomes.

3. Flexibility

Being open to partial exits, staged deals or creative structures can widen the buyer universe and help bridge gaps in expectations.

4. Positioning

Tailoring the equity story to the likely buyer universe – trade vs PE, domestic vs inbound – is essential in a selective market.

From our perspective at Deal Ascent, the most successful M&A transactions in this environment are those where shareholders invest time up front: clarifying objectives, understanding buyer dynamics and preparing the business to stand up to a far more sophisticated level of scrutiny.

For owners considering their next chapter – whether that is a full exit, de-risking a portion of their wealth, or bringing on a partner to accelerate growth – now is the right time to start the conversation.
