The intermediary arm of RBS will also cut its sales managers from four to two.
NatWest’s telephone-based BDMs will not be affected.
The cut in BDMs was part of the ongoing review of the RBS UK retail group and not a part of the 3,500 job cuts announced yesterday from RBS’ investment banking arm.
A spokesman for NatWest Intermediary Solutions, said: “As part of an ongoing UK-wide review of the RBS Group’s Retail operations, NatWest Intermediary Solutions is restructuring parts of its business.
“To reflect the current mortgage market conditions and to continue to operate an efficient and sustainable business, there will be a reduction of roles in its field sales team, sales management and business support teams.”
The spokesman said that NatWest was going through a consultation period with its staff and will hopefully keep redundancies to a minimum by redeploying most of the BDMs into other positions.
He said: “The majority of roles are not subject to any change. We are working through a process with those members of staff affected by this decision. We will do all we can to support our people and to keep compulsory redundancies to an absolute minimum.
"NatWest Intermediary Solutions will continue to be a strategic mortgage channel for the RBS Group and we are committed to offering intermediaries a great range of mortgages that is supported by excellent service.”
Last month NatWest launched its new website for intermediaries which included an instant messaging LiveTALK.
NatWest’s spokesman said it was unlikely that brokers would see a dip in service and that they would still see excellence in their standards.
