Misys said its Countrywide network had signed up eight new members in as many weeks, bringing its total membership to more than 800.
It also said there were more brokers on the verge of joining the network.
Misys Insurance Management head of insurance services John Dawson said: “It is very encouraging that new members are signing up in such a critical year.
“It shows that brokers intend to trade beyond January 2005, but also that they are looking to networks for support and guidance, while retaining their independence.”
