Bank of Ireland has confirmed its ATM and debit card services will be out of action for several hours overnight.

The financial institution says it is due to scheduled IT maintenance.

The outage is due to kick in at 1am in the morning and will be in place until 5am.

Some credit card and mobile top up facilities will also be affected by the planned shut down.

“Some ATM/debit card customers may also be unable to conduct point-of-sale transactions during the same period,” said a statement from the bank.

“Bank of Ireland credit card point-of-sale transactions will not be affected. Credit card holders won’t have service at Bank of Ireland ATMs but will have access to services at non-Bank of Ireland ATMs.

“Customers who top up their mobile phone credit using our 365 Online or our mobile and tablet apps will have the credit applied once the service has been fully restored.

“The Bank of Ireland ATM fleet in the Republic of Ireland, Northern Ireland and UK Post Offices will also be unavailable to any non-customers at that time.

“We apologise to our customers for any inconvenience they may experience during this scheduled IT maintenance.”
