About Gem
Specialist underwriting, built around brokers
Built on experience. Designed to move quickly.
Gem was established to combine the technical knowledge and relationships of an experienced underwriting team with the agility of a focused, independent business.
Our liability team brings more than 60 years of combined experience in the UK market. This depth of knowledge enables us to look beyond a basic trade description, understand the business behind a submission and respond with informed, practical underwriting decisions.
As Gem expands into Professional Indemnity, we are applying the same broker-led principles across our growing product range: accessible underwriters, efficient communication and a willingness to consider suitable risks on their individual merits.

Why Gem
An underwriting relationship you can rely on

That is the Gem difference: experienced underwriting, direct communication and a genuine commitment to making it easier for brokers to do business with us.
