Pioneer Engineering underwrite both Facultative and Treaty engineering risks on a worldwide basis utilising over 30 years of experience in this class of business and strong relationships with key engineering brokers.

Writing both facultative and treaty engineering business is an important differentiator for Pioneer and allows our underwriters first hand experience of relevant facultative market issues when talking to our treaty clients.

We write business on a traditional proportional/ground up basis but we are also willing to consider excess of loss opportunities, where available.

We offer a flexible and consistent underwriting approach to our clients and our brokers.
