Canopius replaces QBE as Castle Insurance underwriter

Castle Insurance, part of Australia’s Sure Insurance , has named Canopius as its new underwriter, replacing QBE Insurance Australia effective December 1, 2026. The arrangement is supported by Canopius’ Lloyd’s Syndicate 4444.

Castle offers home and contents insurance through brokers and has been operating for approximately 12 months. It will continue to manage policy administration and claims, supported by its internal loss adjusters and team members across Australia.

As part of the transition, Castle has updated its product disclosure statements and underwriting guidelines following broker feedback, with expanded features and benefits taking effect December 1.

Sure Insurance Managing Director Bradley Heath said the partnership offers new growth opportunities for Castle, citing the companies’ shared focus on long-term partnerships and specialized risk selection.
