The broker will launch as an appointed representative next month
Castlebridge Risk Solutions has entered into two strategic partnerships ahead of launching next month.
The broker, which will specialise in commercial business and property owners’ propositions, is launching in the UK market on 3 June 2025.
Ahead of going live, the firm has partnered with Cornerstone Finance Group and Imperial Chartered – the move will see the broker provide tailored commercial insurance for their clients.

“Castlebridge Risk Solutions [is] the perfect commercial insurance broker for our growing client base.
“I speak on behalf of everyone here when I say how excited we are to be able to offer such a wealth of expertise to our valued clients.”
