A managing general underwriter (MGU) typically provides specialist underwriting expertise and programme design, often without taking on balance‑sheet risk directly, instead sourcing capacity from one or more insurers or reinsurers. In the UK and London markets, MGUs may operate across lines and geographies, and must demonstrate strong technical capability, data transparency, and alignment with capacity providers’ appetites, while managing regulatory permissions, conflicts of interest, and the need for clear value propositions to brokers and clients.
