The UK lower mid-market M&A landscape (typically covering transactions between £10m and £100m) has entered a more active phase. After the “autumnal hiatus” caused by pre-Budget anxiety late last year, the market is finding its footing.

Stability has returned to the market, and while buyers remain disciplined, the outlook for the rest of the year is constructive rather than hyper-inflated.

2026 first-half review: What has driven the market?
The first few months of the year have been defined by a transition from defensive restructuring to selective, strategic execution.

The post-Budget release: The late-2025 Autumn Budget created a temporary logjam as founders waited for tax clarity. Because the worst-case Capital Gains Tax (CGT) spikes didn’t materialise, dealmakers breathed a sigh of relief. This unleashed a wave of deferred exits. Additionally, a rush of business owners pushed to complete transactions before the Business Asset Disposal Relief (BADR) rate increased from 14% to 18% in April 2026.

The macroeconomic tailwinds: Inflation has stabilised near the 2.5%–3% mark, and the Bank of England’s base interest rate has reliably eased downward from its 5.25% peak. This predictability in financing costs has narrowed the gap between what sellers think their business is worth and what buyers are actually willing to pay.

A “two-speed” recovery: The mega-deal space has bounced back sharply, driven by corporate scale-building and public-to-private takeovers. In the lower mid-market, volume hasn’t expanded as rapidly as value. Buyers are moving decisively, but they are hyper-focused on earnings quality. “Average” or under-prepared businesses are still sitting on the shelf, while premium assets face intense bidding wars.

Outlook for the rest of 2026
As we look toward the second half of the year, expect a steady, theme-driven acceleration across the lower mid-market.

The PE exit pressure valve: Private Equity (PE) firms are holding a massive backlog of ageing portfolio companies that they desperately need to exit to return cash to their Limited Partners (LPs). For the rest of the year, PE will be a dominant force on both sides of the table.

Because traditional IPOs remain muted, PE houses will rely heavily on trade sales to corporate buyers or sponsor-to-sponsor (secondary) buyouts. In tandem, their “buy-and-build” strategies will continue to drive lower mid-market volume via smaller bolt-on acquisitions to expand existing platforms.

Corporate “portfolio reshaping” and carve-outs: Corporate buyers are shifting from cost-cutting to chasing inorganic growth. Large caps are actively pruning their structures to focus on core operations. This is creating a rich pipeline of carve-outs and divestments, giving lower mid-market buyers a unique opportunity to acquire high-quality, stable business units that just need independent operational focus to thrive.

The AI screen: Artificial Intelligence has shifted from a buzzword to a strict investment filter. Buyers are intensely scrutinising targets for AI resilience and integration potential. Tech-enabled service firms that leverage automation are commanding premium multiples, while businesses heavily exposed to AI disruption are finding a shrinking buyer pool.
