The London’s Leading Underwriter Report is an independent ranking of underwriters operating in and around the London Market. The 2024 London’s Leading Underwriters Report garners around 500 underwriter nominations, covering over 800 individual underwriters from over 110 insurance companies.

Underwriters are nominated by a representative cross-section of underwriting peers from across all main business classes and separately, brokers working in the London Market. Underwriters are then ranked according to the number of endorsements each receives for being regarded as market leaders.
