The funding will also see over 30 new ATMs rolled out in the region.
A midlands bank will be refurbished as part of a €60 million investment.
Bank of Ireland's latest round of funding will see new state-of-the-art ATMs installed at every branch in the country, including 31 in Laois, Offaly and Westmeath.
It says the new fleet of 664 machines will have greater cash processing capacity and will slash energy use by more than half, and will be rolled out between now and 2027.
The investment will also see 18 branches, including the site in Birr, refurbished, with some of those to see improved access in some locations, while colleague facilities will be upgraded in others.
Sinn Féin MEP Chris McManus says he wants assurances Bank of Ireland’s ATMs won’t replace staff members:
Susan Russell, CEO, Bank of Ireland Retail Ireland says:
"Like any other company, being profitable allows us to improve our business.
Given the large number of customers which we serve, major re-investment is required every year. I’m really happy that this latest investment will see all customers across all counties benefit with the most modern and efficient ATMs, whilst also supporting our ESG ambitions through energy reduction.
We are always investing to ensure customers have access to cash and other banking services in a modern and comfortable environment. Each year we refurbish many of our branches and that’s a constant, rolling project of enhancements.
As a full service retail bank, with a presence in communities throughout the island of Ireland, we are committed to continually improving our services and the financial wellbeing of customers.
This means re-investing purposefully in branches, contact centres, technology, ATMs and other infrastructure to ensure our customers have the most modern and efficient banking available."
