Councillors attacked NatWest over its decision to permanently close its Long Buckby branch at a meeting held on Monday.
The branch is to close on November 24, amid falling numbers of customers visiting to do business over the counter.
This will mean people wishing to manage their accounts face to face will have to travel to the NatWest branch in Daventry or use Long Buckby Post Office.
Stephen Osborne, chairman of Long Buckby Parish Council, criticised the plans.
He said: “There has been no consultation on it. People come from other villages to use the bank. Not every body wants to go to the post office. It’s a small room, there is no privacy.
“We just lost two appeals for 230 houses. Surely 230 houses would give the bank 200 more bank accounts. It is a commercial decision.”
The parish council plans to write to NatWest to express members’ concerns, as well as Daventry MP Chris Heaton-Harris, who previously backed a campaign in 2010 opposed to cuts in opening hours.
