Britain’s merger and acquisition market is hurtling towards a record year – yet private equity firms are being increasingly frozen out of the biggest deals. UK M&A value has already reached £178.9 billion in the year through July 7, putting the market on track for an annualised total of around £347 billion, according to PitchBook data. That would eclipse the previous high of £309.2 billion set in 2015.
The surge is being driven by corporate buyers, who have used financing options that private equity sponsors cannot easily replicate. The top 10 deals accounted for roughly 52% of overall M&A value, and within that elite tier, PE sponsors captured just 15.1% – a dramatic underperformance compared with their historic share. Across the entire market, sponsor acquisitions made up only 33.1% of deal value in the first half of 2026, the second-lowest proportion since 2014. Normally, PE firms account for between 40% and 55% of the market.

The widening gap at the top suggests that while the overall M&A boom is benefiting corporate balance sheets, private equity is struggling to compete for the largest targets. The trend raises questions about whether PE will be able to regain its footing as interest rates and financing conditions evolve, or whether the era of sponsor-led megadeals is giving way to a new cycle of corporate consolidation.
