A total of 37 jobs will go across Moville and 13 other branches on a hit list released today by the bank’s public relations department.
A further ten branches are to be closed in the North.
The bank claimed the decision to close any branch is made on a case-by-case basis, based on local information.
“Banking has changed significantly over the last few years as more and more of our customers are using digital technology to bank with us where and when it is convenient for them. As a result, only 13% of transactions happen in branches in the Republic of Ireland,” the bank said in a statement.
“We continue to invest in a range of channels to respond to how our customers prefer to do their banking,” the statement added.
The branches to close are located in Athboy, Co Meath; Ballinrobe, Co Mayo; Ashbourne, Co Meath; Athy, Co Kildare; Castleblaney, Co Monaghan; Castlerea, Co Roscommon; Clones, Co Monaghan; Croom, Co Limerick; Ferbane, Co Offaly; Loughrea, Co Galway; Manorhamilton, Co Leitrim; Moville, Co Donegal; Roscrea, Co Tipperary and Wicklow town in Co Wicklow.
Ulster Bank said it had written to customers in Inishowen and said it was also “communicating directly with staff” in the Moville branch.
Ulster Bank is part of the controversial RBS Group which has faced huge fines recently.
It was also under fire amid claims to deliberately put some companies out of business.
