About IISL Underwriting
An MGA built for specialist underwriting.
01 — Who we are
A specialist MGA within an established group.
IISL Underwriting is a specialist UK Managing General Agent and part of the InShare Group. We focus on commercial insurance solutions developed with brokers, insurers and distribution partners — combining underwriting expertise with the operational strength of the wider group.
02 — How we underwrite
Decisions made close to the risk.
Our underwriters make decisions based on the individual characteristics of each risk, within a clearly defined appetite. Brokers deal directly with the people who make the decisions — supported by disciplined referral processes and a pragmatic, commercial mindset.
03 — Our approach to partnerships
Long-term, not transactional.
We build partnerships with brokers, affinity organisations and insurers that are designed to last. That means honest conversations about appetite, shared visibility of performance, and propositions developed together rather than imposed.
04 — Governance and oversight
Discipline our partners can rely on.
Underwriting authority carries responsibility. Our governance framework covers underwriting controls, product oversight, management information and portfolio review — giving insurer partners confidence in how their capacity is deployed.
