What Miller Insurance Services does

Its distribution is wholesale/specialty broker-led, placing business through Lloyd's and international markets, and it increasingly runs delegated authority programmes and tech-enabled follow facilities such as MillerBoost (powered by InsurX) on Lloyd's A+ capacity.
