The team, which is already active, discusses fresh mortgage products which are offered on the same rates available to new customers and further advance opportunities.
Charles Haresnape, managing director of residential mortgages, said: “We see this as the natural evolution of a new lender and we are still heavily intermediary focussed.”
Aldermore has been lending residential mortgages since May 2010 and predicts it will have more than £1bn worth of customers by January 2013.
It had not been necessary for the bank to set up a retention team until now as the minimum product tie-in period had been for two years.
Haresnape added: “It is simply good customer service to offer your existing customers a further great deal.”
