Lloyd’s Bank in Mildenhall is to close along with another 28 other branches and a further 15 Halifax branches across the country.
Lloyd’s Banking Group, who own both Lloyd’s Bank and Halifax, blamed a lack of customers as many move to digital banking.
The move comes in addition to previous announcements and means a total of 100 branches will close this year.
The Unite union condemned the move, saying the bank was “walking away from local communities”.
Unite national officer Caren Evans said: “The decision to further erode its presence within our communities is baffling.
“The closure of 44 more bank branches will deny our communities of essential services such as access to cash and experienced highly trained staff. A local ATM is not a suitable alternative to a staffed bank branch.”
The bank said a third of the branches which were closing were located in large towns and cities, with another branch nearby.
Vim Maru, the group’s retail director, said there had been considerably fewer transactions at these branches in the last five years.
He added: “Like many businesses on the high street, we must change for a future where branches will be used in a different way, and visited less often.”
