Churchill is rolling out a motor policy exclusively to high street brokers connected to Software Solutions Partner networks (SSP).
The policy, which is already available through Churchill Direct, will be rolled out to around 550 members of SSP's business network, Key Choice, next month.
Churchill head of broker division Trevor Brittain said: "The move will increase our broker portfolio by 30%.
"We aim to make £10m gross premium in the next 12 months by selling 50,000 policies through high street brokers.
"At a time when consolidation and market conditions have reduced capacity and choice of underwriters, Churchill is delighted to show support for brokers by adding its car insurance product to the Key Choice range."
