In Q3, the UK M&A market demonstrated resilience and strategic focus:

  • Deal value surged by over 100% from levels reported in Q2, even as deal volume declined by 21%, signalling a clear shift towards fewer but more impactful
    transactions.
  • Year-to-date, 4,719 deals have been announced with an aggregate value of £132bn.
  • SMEs continued to drive activity, accounting for approximately 86% of all disclosed-value deals.
  • International interest remained strong, with US acquirors leading investment, and Sweden, Ireland, and France prominent among European buyers.

The UK M&A market showed resilience in Q3, with a strong rise in deal value reflecting a shift toward fewer, higher impact transactions. International interest remained robust, and SMEs continued to play a central role in driving activity. While private equity remains a key force, corporate buyers are increasingly active across both domestic and global markets. As we approach year-end, the Autumn Budget is expected to influence deal flow, while stabilising economic conditions and sector-specific momentum support a cautiously optimistic outlook for the remainder of 2025.
