Broker FMW Risk Services is moving to Acturis from Sectornet.
FMW managing director Peter Blanc said: "We were looking for a system that would take us successfully into the post-FSA world of 2005 and beyond. The Acturis Broker Platform has offered us a mix of richness of commercial lines functionality and also ease of implementation to minimise disruption.
Acturis sales and marketing manager Simon Ronaldson said: "FMW will take us over the 1,500 user mark, which is well ahead of where we expected to be at the turn of the year. 2005 looks brighter still."
