We are a dynamic, cutting-edge underwriting agency, providing unrivalled coverage in the MGA/MGU arena. We take a flexible, collaborative approach to underwriting, working with the broker to meet their client’s needs.

This approach has allowed us to rapidly expand our business and we now have nineteen underwriting teams across seven locations.


Pioneer Underwriters launched in April 2011 and trades as both a risk carrier and MGA/MGU with full delegated underwriting authority in over 120 Lloyd’s class codes using a pre-analysed broker portfolio as its foundation. Pioneer operates with the backing of Liberty Syndicate 4472 and manages circa £200m of premium. Pioneer’s 19 underwriting teams operate over 23 underwriting facilities via both Lloyd’s and Non-Lloyd’s platforms across Property, Marine and Casualty classes. Pioneer is backed by 19 markets, has TOBA’s with over 130 London and overseas brokers and nationwide distribution capability across the US.

Our MGA businesses are individually backed by A- or better rated carriers and follow the Pioneer Underwriting ethos of tailored solutions backed by excellent customer service.
