UK Investment Sector M&A Activity Slows In May

There were three investment sector deals announced above £5m of value in May. While smaller deals continue to dominate overall activity (accounting for 57% of transactions YTD), 2026 has seen the highest proportion of £100m+ transactions on record (32%).

M&A Market Update 

May saw a quieter period for M&A activity in the investment sector, with only three transactions above £5m announced – making it the lowest monthly deal volume of 2026 to date and bringing the year‑to‑date (YTD) total to 28. 

The May deal count included two transactions in the independent financial adviser market, with Advies Private Clients acquiring St Andrews Financial and AAB Wealth acquiring BpH Wealth Management. Elsewhere, Isio announced the acquisition of Collidr, an artificial intelligence and investment management consultancy.

Deal values in May were concentrated at the lower end of the market, with all transactions falling within the £5–25m range. It also marked the first month in 2026 without a deal exceeding £100m in value. 

However, while smaller deals continue to dominate overall activity (accounting for 57% of transactions YTD), 2026 has seen the highest proportion of £100m+ transactions on record (32%), highlighting a growing concentration of activity at the top end of the market. In contrast, the mid-market (£25–100m) has declined notably relative to prior years. 

As demonstrated by May’s activity, smaller bolt-on acquisitions remain a key strategic focus for acquirers.

Two of the three acquisitions in May were completed by private equity-backed (PE) acquirers, with the third completed by a privately-owned acquirer (albeit with funding also from PE). The share of deals involving PE has increased significantly, rising from c.31% in 2020 to c.64% in 2026. 

This shift reflects sustained financial sponsor interest in the investment sector’s attractive characteristics, with demand particularly focused on wealth management businesses. The continued rise in PE‑backed activity highlights the growing institutionalisation of the sector, with sponsor‑backed consolidators playing an increasingly dominant role in driving transaction activity.
