What Chaucer does

Chaucer is a privately held global specialty (re)insurance group operating through Lloyd's of London Syndicates 1084 and 1176, headquartered in London with approximately 590 employees across offices in the UK, Singapore, Dubai, Miami, Bermuda, Copenhagen, and other locations. The company provides specialty insurance and reinsurance across a broad portfolio including cyber, marine, property, casualty, energy, nuclear (where it is described as the world's leading insurer), satellite, healthcare professional liability, political violence, and emerging risks such as AI liability and carbon credit delivery. It serves three primary customer segments: global enterprises requiring complex specialty coverage, primary insurers and reinsurers seeking treaty capacity, and coverholders/Lloyd's market brokers operating under delegated authority.

The business distributes products through the Lloyd's market framework (brokers, coverholders, and direct international offices) and prices risk on a quote basis, generating revenue primarily through insurance and reinsurance premiums collected annually. Underwriting is supported by data-led decision-making, including integration of real-time vessel telemetry via the Ceto Watchkeeper platform for marine hull business. Chaucer's broader product stack includes established lines (Cargo & Specie, Ports & Terminals, Renewable Power, US Casualty Reinsurance, Agriculture Treaty, Accident & Health Reinsurance, Healthcare Professional Liability) alongside recently launched solutions (Vanguard Cyber, Vanguard AI coordinated structure, AI third-party liability with Armilla AI, Carbon Purchase Protection Cover with Kita, and the Ceto Marine MGA). The group is a wholly-owned subsidiary of China Re (Group) Corporation, a publicly listed Chinese reinsurer on the Hong Kong Stock Exchange, which provides capital backing while Chaucer operates independently within the Lloyd's market.
