Our underwriters have the capability and expertise to lead all of the business they underwrite and in many of our business lines will be the leading Lloyd’s syndicate. Our underwriters are empowered to make decisions backed by their own expertise and experience.

Atrium provides delegated underwriting authority to Lloyd's coverholders through the effective use of Binding Authorities and our control, management and hands on approach makes us the preferred underwriter of many leading Lloyd’s Brokers.

Providing almost unrivalled accessibility the majority of Atrium employees sit and operate from within the Lloyd’s building, truly making London and Lloyd’s our base.
