Colsell will replace Christina McComb, who will step down from the role at the annual general meeting June. 

McComb has held this position since Engage Mutual merged with Family Investment in 2015 to create the OneFamily.

After overseeing this merger, McComb has led a modernisation programme at the organisation. This has focused on business growth, creating efficiencies and improvements in customer services. The mutual operates in a number of business areas, including the growing lifetime mortgage market.

Colsell is a fellow of the Institute and Faculty of Actuaries and has worked across banking, insurance, wealth management and mortgage lending sectors during his career. 

His appointment is subject to the usual regulatory approvals. Colsell says “The business will retain its focus on long term sustainability and creating and protecting value for our members, alongside keeping social responsibility, diversity and inclusion right at its heart.”
