UK Mid-Market Buy-and-Build Activity Drops 61% in 2025 After 2024 Peak

Why It Matters

The sharp contraction signals a temporary pause in UK mid‑market M&A, but ample dry‑powder and sector resilience suggest the buy‑and‑build engine will reignite once confidence returns.

Key Takeaways

• Add‑on deals fell 61% to 44 transactions in 2025
• Business services still dominate, making up 36% of deals
• Insurance and education bolt‑ons plunged over 80%
• PE firms now prioritize integration over new acquisitions
• Dry‑powder remains ample, supporting future buy‑and‑build

Pulse Analysis

The 2024 surge in UK mid‑market bolt‑on activity set a five‑year high, driven by private‑equity appetite for fragmented, cash‑flow‑rich sectors such as business services and insurance. That momentum carried 114 add‑on deals, but the subsequent 2025 decline to roughly 44 deals reflects a classic post‑peak correction amplified by geopolitical tension, domestic policy shifts, and lingering inflationary pressures. Investors chose to pause, focusing on operational integration rather than chasing fresh targets, a pattern that often follows an unusually active year.

Sectoral analysis reveals a bifurcated landscape. Business services retained a 36% share of transactions, underscoring its defensive, recurring‑revenue profile. Financial services and consulting together contributed another 32%, while technology bolt‑ons collapsed by 80% as capital migrated toward artificial‑intelligence initiatives. Traditional strongholds like insurance and education suffered steep drops of 85% and 71% respectively, indicating that even resilient verticals are not immune to macro uncertainty. The AI buzz is reshaping PE priorities, prompting a tactical shift from platform expansion to strategic stakes in future‑tech ventures.

Looking ahead, Stevens & Bolton expects the slowdown to be transitory. With substantial dry‑powder still unspent and a cohort of integrated platforms poised for value creation, the market is primed for a rebound once economic sentiment stabilises. A modest improvement in confidence could see deal volumes return to pre‑2024 levels or higher in 2026, reigniting the buy‑and‑build engine that remains a cornerstone of UK mid‑market M&A strategy.
