Broker Rossborough Group has dropped the Sirius PolicyMaster system for personal lines in favour of CDL's platform.
The CDL system will cover private car, good vehicles, motorcycles, home, travel and breakdown insurance.
Rob Hewlett, personal lines director at Rossborough, said: "We have growth plans which includes making acquisitions in the UK. We needed to change our IT system and it was vital that we have a robust and scalable IT platform to support further expansion."
He said Rossborough would continue to use Sirius for its commercial lines business.
