In October 2025, B.P. Marsh & Partners Plc acquired a 10% shareholding in Oneglobal, a London-based international retail and wholesale insurance broker majority-owned by J.C. Flowers & Co.

Founded through the merger of two existing J.C. Flowers-owned Lloyd’s brokers in 2018, Oneglobal now operates across 15 offices worldwide, including Europe, Asia, the Americas, and the Middle East. It specialises in a broad range of insurance lines, including marine, property, aviation, financial lines, energy, and casualty, with forecast brokerage revenue for 2025 of approximately £50m.

The investment will provide Oneglobal with strategic growth capital to support its expansion, initially through the acquisition of a Bermudian specialty insurance broker and further development into the Asian market.
