The deal, which was announced subject to regulatory approval in July this year, was completed on 1 November.
The Exeter has confirmed that it will continue to offer the One Fund corporate cash plan to help companies meet their employee benefit needs, and will also offer a Health Cash Plan to individuals via its new website.
Existing policyholders have all been contacted about the move to welcome them to The Exeter and inform them that their premiums and policies have not changed as a result.
Commenting on the announcement, Chief Executive Andy Chapman said:
“I’m delighted that we have completed this important acquisition, increasing both the scale and breadth of our organisation.
“Not only are we confident that we will offer existing policyholders a great service experience, we also have aspirations to improve this further for individual and corporate cash plan customers old and new.”
