Insurance Times rounds up the top five stories making headlines across the market from 29 September to 3 October 2025.

The week began with news that green motor broker The Green Insurer would close less than two years after launch, after failing to secure new investment. The carbon-offsetting focused broker confirmed that all customers would be transferred to Cornmarket Insurance Services.

Later in the week, Ageas UK confirmed a reshaped leadership team as it officially began the integration of Esure, acquired from Bain Capital earlier this year.

UK chief executive Ant Middle announced a line-up of senior leaders drawn from both businesses, including new roles across broking, underwriting, claims and finance. The insurer said the changes would provide a platform for a unified, sustainable business.

Korean insurer DB Insurance revealed it would acquire Florida-based specialty insurer in a deal with Tiptree and Warburg Pincus.

Fortegra, which only last year gained regulatory approval to launch a UK subsidiary, will now join DB Insurance’s global network. The firm said the deal represents the largest US market entry by a Korean non-life insurer.

Private equity firm BP Marsh agreed to acquire a 10% stake in specialty broker Oneglobal for £10m.

Backed by JC Flowers, Oneglobal expects £50m in broking revenue this year and plans further international expansion, including acquisitions in Bermuda and Asia. BP Marsh said the deal provided an “exceptional opportunity” to back a fast-growing London market intermediary.

Rounding off the week, JMG Group expanded its regional footprint with the acquisition of three brokers: Boston Insurance Brokers in Solihull, Hayton Insurance Brokers in Kendal, and Gateway Insurance Services in Edinburgh.

Chief executive Nick Houghton said the businesses would retain their leadership teams and regional identities, while benefiting from JMG’s scale and market access.
