The Norwich and Peterborough Building Society branch in Spalding is to close.
The brand is being abolished by owner Yorkshire Building Society, which is closing 28 N&P branches and 20 Yorkshire Building Society branches from September this year. More than 400 jobs will be at risk by the move.
The society plans to close its N&P current accounts to existing customers, and withdraw the N&P brand from the high street over the next year.
Yorkshire Building Society chief executive Mike Regnier said: “The driving forces behind the proposed branch closures are shifts in market conditions and an increasing desire among customers to transact digitally rather than on the high street.
“We therefore no longer believe it is the right commercial position for us to continue to maintain these 48 branches across the N&P and Yorkshire network.”
The Spalding branch in Sheep Market will go along with others nearby in Bourne, Market Deeping and Stamford.
