Who we are

We are a leading specialty insurance group providing clients with proven smart risk solutions for underwriting and claims.

Our enterprising and trusted experts offer market-leading cross class capabilities, empowered decision-making and a tailored approach.

Leading business in major classes

We are established and trusted leaders in all major insurance and reinsurance classes, underwriting across international marine and non-marine markets through Syndicate 1084, and Syndicate 1176, a market-leading insurer of nuclear risk.

Global reach

With our headquarters in London, and our international hubs for Europe, Latin America and Asia, we protect clients in over 200 countries and territories worldwide.

Supported by The Hanover

Our clients also benefit from the commitment of our parent company, The Hanover Insurance Group, Inc. one of the largest insurance businesses in the United States. The Hanover provides standard and specialised insurance protection for small and medium sized businesses, as well as for homes, automobiles, and other personal items, through a select group of agents and brokers.

With $5.8 billion of gross written premiums and shareholder equity of $3.0 billion in 2017, The Hanover provides Chaucer with a strong financial foundation.

A rich heritage

We can trace our underwriting roots back to modest beginnings in 1922. And today, our future focus confidently builds on over 95 years of experience.
