The UK financial services sector experienced a dramatic upswing in Mergers & Acquisitions (M&A) activity during the first half of 2026. Deal values skyrocketed to £33.7 billion, an eight-fold increase from the £4.2 billion recorded in the same period of 2025, according to new data from EY. This surge in value was accompanied by a significant rise in the number of announced or completed deals, which grew by 25% year-on-year. A total of 135 deals were publicly disclosed by UK banks, insurers, and asset managers between January and June 2026, up from 108 in the previous year.
This robust performance indicates a strong recovery in the M&A market, which had faced headwinds from economic and geopolitical uncertainties in late 2025. EY’s analysis points to a clear strategic imperative behind these transactions: the enhancement of technology and artificial intelligence (AI) capabilities. A quarter of investors surveyed by EY identified technology access as their primary objective when considering deals. The market also saw significant scale, with seven deals exceeding £1 billion in value, including two substantial “megadeals” each valued between £8 billion and £10 billion, which together accounted for approximately 93% of the total deal value.
Damian Hourquebie, EY UK financial services strategy and transactions leader, commented on the strong first half, attributing the positive momentum to supportive market confidence. He highlighted that strategic consolidation is a key theme, aimed at driving revenue growth, fostering innovation, and accelerating transformation. Despite persistent geopolitical and economic uncertainties, the sustained M&A activity from the latter half of 2025 into the first half of 2026, particularly the emphasis on tech-led acquisitions, suggests that UK financial services leaders are making bold, strategic decisions to secure future growth.
