BDO advises on more than 250 deals with combined value of £10.9 billion
BDO has advised on 257 deals in 2025, with a combined value of £10.9 billion, demonstrating the resilience of its client base, as well as the firm’s sector and regional strengths.
Across the year, over 60% of the transactions that BDO advised on had private equity involvement and over 40% had a cross-border element.
Deal activity spanned a wide range of sectors, with standout performance across TMT (55 deals), manufacturing and engineering (39 deals), healthcare, pharma and life sciences (37 deals), and real estate (28 deals).
Gurpal Ahluwalia, Head of Deals, said: “We saw the 2025 deal market rebound strongly in the second half of 2025, with an increase in deal volume and value in this period across BDO’s core sectors. This suggests a trend towards an increase in deal value reflecting renewed confidence and strategic activity across the UK market.
“Private equity continues to drive momentum and investment activity. We’ve seen an uplift in companies pursuing bolt-on acquisitions and innovative deal structures to create value and drive growth. Debt Advisory services have also experienced a notable uptick as businesses seek creative funding solutions to maintain deal flow.
“Of course, the macro environment remains unpredictable, with geopolitical uncertainty and evolving investor priorities. However, going into 2026, there’s cause for cautious optimism. At BDO, regional markets, particularly the Midlands and Scotland, are showing strong activity.”
BDO has been named the No 1 Financial Due Diligence provider UK and Ireland in the Mergermarket UK Accountant League tables 2025 by deal volume for the fifth consecutive year.
Derek Neil, Head of Transaction Services at BDO, added: “Deal preparation and diligence are more rigorous than ever, with heightened focus on the visibility of future performance, as well cyber security, AI, and tax. The best prepared businesses have considered these areas pre-deal, and this is critical to maximising value.
“ESG remains a critical value driver, with buyers and investors demanding robust strategies and data. Upcoming UK legislation is expected to reignite ESG discussions, making it a timely area to focus on for dealmakers and companies looking towards an investment event."
