Foreign Investment Surge: Inward M&A Reaches Five-Year High in Fourth Quarter 2025

—

Inward mergers and acquisitions involving UK companies reached their highest level in over four years during the final quarter of 2025, signalling a renewed appetite among international buyers for British businesses. However, this surge in foreign investment comes as domestic deal-making activity and UK companies’ overseas acquisitions both declined in value, painting a mixed picture of Britain’s deal-making landscape.

The Office for National Statistics reported that inward M&A—transactions where foreign companies acquire UK firms—climbed notably in the fourth quarter of 2025, reaching the highest total since the second quarter of 2021. This represents a significant reversal after several quarters of more modest foreign investment activity, suggesting that international confidence in British assets may be rebounding despite broader economic uncertainties.

The uptick in inward M&A contrasts sharply with weakness elsewhere in the M&A market. The value of domestic acquisitions—where UK companies purchase other British firms—fell during the quarter, continuing a trend of relatively subdued internal deal-making. Similarly, the value of outward M&A, representing UK companies acquiring foreign businesses, also decreased, indicating that British firms are pulling back from international expansion through acquisition.

The weaker performance in domestic and outward M&A reflects broader economic conditions facing British businesses. Throughout 2025, UK M&A activity remained somewhat constrained. In the second quarter of 2025, domestic M&A was valued at £3.4 billion, whilst outward M&A fell sharply to £4.0 billion. By the third quarter, domestic M&A recovered slightly to £5.3 billion, but outward M&A continued to decline to £3.4 billion.

The Office for National Statistics has previously noted that mergers and acquisitions involving high-value transactions “remain weak”, suggesting that UK companies face headwinds when seeking acquisition targets abroad, whether through cost pressures, financing constraints, or strategic caution. Domestic deal-making, meanwhile, has shown modest recovery but remains below levels seen in previous years.

The strength of inward M&A in the final quarter, reaching five-year highs, suggests that foreign investors view UK assets as attractive relative to other opportunities. This may reflect several factors: the relative valuations of British companies following previous currency movements, specific sector opportunities that international buyers find compelling, or simply renewed confidence in the UK as a destination for overseas capital.

Inward M&A provides important capital investment into the UK economy and can bring strategic expertise, operational improvements, and market access to British firms. For many sectors—including financial services, technology, pharmaceuticals, and manufacturing—international ownership brings investment and employment opportunities.

The divergence between inward and domestic M&A activity reflects distinct dynamics in Britain’s business landscape. Whilst foreign investors demonstrated increased appetite for British businesses in late 2025, UK-focused deal-making remained modest. This pattern suggests that international capital is flowing into the country, but British companies themselves are conserving capital and proceeding cautiously with acquisitions.

The number of deals and their values matter differently for the economy. A smaller number of large foreign acquisitions can mean significant economic impact, whilst a larger number of smaller domestic deals may indicate more widespread business dynamism. The surge in inward M&A values in the fourth quarter suggests that several substantial international acquisitions completed during this period.

Key Takeaways

• Foreign investment in UK companies reached a five-year high in Q4 2025, rebounding after several quarters of slower inward M&A activity
• Domestic M&A (UK companies acquiring other UK firms) saw values decline, reflecting continued caution amongst British acquirers
• Outward M&A also fell, indicating UK companies are restraining overseas acquisition activity
• The divergence between strong inward investment and weaker domestic deal-making underscores different confidence levels between international and domestic buyers

What This Means for Kent Residents

For residents and businesses across Kent, the resurgence in inward M&A carries important implications. International acquisitions of UK firms often lead to investment in facilities, workforce development, and technology integration. Kent’s strategic position as a gateway to Europe—through Dover, the Channel Tunnel at Folkestone, and HS1—makes it an attractive location for foreign acquirers seeking European distribution and operational hubs. When multinational companies acquire British businesses, they frequently maintain and expand UK operations, creating employment opportunities and potentially stimulating local economies. However, the weakness in domestic and outward M&A suggests that British business confidence remains constrained, which may limit expansion and investment at smaller and medium-sized enterprises throughout the region.
