Wesleyan Assurance Society has announced the acquisition of the Practice Plan Group, a provider of practice-branded dental membership plans.
The mutual has also acquired Medenta, a provider of patient finance to UK dental practices.
Wesleyan said this move has strengthened its position in the dental market where it has previously provided specialist financial advice and services to dentists.
Craig Errington, chief executive at Wesleyan said: "The acquisition of Practice Plan is part of a larger strategic growth programme that we are embarking upon over the coming years.
"Until now we have largely focused on providing personal financial services to dentists. Practice Plan is a strong and successful business and will play an integral role in helping us to grow our commercial offering to dental practices."
Practice Plan has been acquired from UK mid-market private equity firm Dunedin and shareholders and the transaction is subject to regulatory approval.
Wesleyan was advised by Fenchurch Advisory Partners and law firm Pinsent Masons, and Practice Plan's shareholders were advised by Deloitte and law firm Addleshaw Goddard.
