John Malone, managing director at Premier Mortgage Service has committed to staying with the firm for at least another 18 months.
Malone was expected to become chairman of PMS and a search has been underway for his successor.
But Bankhall says that it will not be looking for a replacement anytime soon.
Rumours had been circulating the industry as to who would replace Malone, with Linda Will, former-managing director at Accord Mortgages, being hotly tipped to be a favourite for the role.
Steve Atkins had been in line to succeed PMS until he unexpectedly resigned as head of Premier Mortgage Services in September 2007.
