Captive insurance involves UK corporates, multinationals with UK operations, and public‑sector bodies using their own licensed insurance vehicles—onshore or in international domiciles—to retain and finance risk in a more strategic way. Risk and finance teams work with brokers, consultants, and fronting carriers to structure programmes, optimise reinsurance and capital, and extend captives into emerging or hard‑to‑place risks, while maintaining robust governance and compliance with Solvency II‑style regulatory expectations.
