Most recently Green was head of mortgage products at Lloyds Banking Group and his previous experience includes stints at First Direct, NatWest and Prudential.
Green said: “My teams will ensure we continue to provide sustainable savings and mortgage products for our members, products which offer fair value without onerous conditions.
“We’re also responsible for developing the new products which will face in to the very real challenges of home ownership in the 21st century.
“My background is a combination of Retail and Financial Services but I tend to find that most banks have an inbuilt ability to over-complicate life.
“Mortgages and savings are everyday products that customers need and use, but you shouldn’t need a degree to understand how they work.
“My new role presents a great opportunity to be different, to listen to our customers and build the products they want and need.”
