Ingham will be responsible for NatWest Intermediary Solutions relationships with Personal Touch, Intrinsic, Simplybiz and Mortgageforce.
Ingham has spent the last three years in the NatWest retail arm as a local chief executive responsible for 14 branches in Norfolk and Suffolk and has been with the RBS Group for nine years in a variety of sales management roles.
Graham Felstead, head of the intermediary channel, said: “I am delighted to welcome somebody of Andy’s calibre on board.
“Not only does he have a really good grasp of the intermediary sector he brings with him a depth of retail experience that should be a real aide in the relationships he has with his major accounts.
“Having worked with Andy previously, I know that he is a determined and driven individual who will work studiously with his intermediary firms to develop strong and profitable partnerships.”
Ingham will take up his new position on 18 March and will be replacing Richard Walker who is joining Virgin Money.
Felstead added: “I would also like to wish Richard the best of luck with his new role at Virgin Money.
“Richard has been an integral part of the development of the NatWest Intermediary Solutions’ proposition and he has been very successful in cultivating prosperous relationships with some of the country’s biggest intermediary firms. We will miss his energy and enthusiasm.”
