Duncombe (pictured) joins from Legal & General Mortgage Club, where he was director.
He is to start his new role at Accord from March 19 and is charged with driving forward the lender’s position in the intermediary market.
Charles Canning, managing director at Accord, said: “I am delighted to announce Jeremy’s appointment to this newly-created role.
“He is a familiar face to many in the intermediary market and has a wealth of mortgage experience and will be a great asset to Accord and the Yorkshire Building Society (YBS) Group.
“Accord has developed significantly over the past few years building a reputation as a formidable lender in the broker market.
“We have exciting plans to further develop our mortgage propositions and the service we provide to mortgage brokers in the intermediary market.
“Having Jeremy at the helm puts us in a strong position to deliver them.”
Duncombe added: “This is a very exciting time to be joining Accord and the YBS Group as it continues to strengthen the support it provides brokers.
“I’m really looking forward to getting started, ensuring brokers remain at the heart of all future developments.”
David Robinson and Chris Maggs are to continue in their roles at Accord as national intermediary sales manager and buy-to-let commercial manager respectively, and work closely with Duncombe, according to the lender.
It comes shortly after Stephen Smith left Legal & General as director of housing strategy – it has today been announced he will join Mortgage Advice Bureau as non-executive director.
Mark Holweger, managing director Legal & General Insurance partnerships, said: “We can confirm that Jeremy Duncombe will be leaving Legal & General Mortgage Club in March 2018, and thank him for his contribution.
“Jeremy leaves the Mortgage Club in a strong position, with a highly experienced team that hold great relationships with brokers and lenders alike.
“Jeremy’s role will be replaced and we are looking to make an announcement in the near future.”
