Bank of Ireland is investing over €2m in a consumer awareness campaign to support consumers who are moving banks over the coming months.
From this week, Bank of Ireland's "Big Move" campaign will feature on TV, radio, print, outdoor, digital and social media.
The campaign directs account movers to a range of supports including step-by-step guides, a dedicated phone line and an online hub to help them with the move.
Up to one million current and deposit account customers are looking for new banks ahead of the departure of Ulster Bank and KBC Bank Ireland from the Irish market.
Bank of Ireland said that so far this year it has opened double the number of personal current accounts compared to the same period last year.
To help manage the huge increase in applications, about 500 additional staff members are being dedicated to support customers moving.
Bank of Ireland noted that seven in ten accounts are currently being opened via digital channels.
Gavin Kelly, CEO of Retail Ireland, Bank of Ireland, said last month the bank announced a range of additional resources to support those consumers moving banks.
"We are now adding to this with a comprehensive consumer awareness campaign to provide further guidance," he added.
"Ireland has never seen this level of account switching, which is a major logistical issue for consumers as well as banks, utility companies, Government Departments, and the wider business community," Mr Kelly said.
"It's a serious challenge and it requires serious investment and resources. Bank of Ireland has moved swiftly to put a range of supports in place for consumers and our "Big Move" campaign will now guide people towards those supports," he added.
Bank of Ireland said its new dedicated online hub includes a guide for customers on how to close their existing current account, open a new account, make changes to regular payments and apply for overdrafts.
Templates for letters to SEPA Direct Debit originators, payroll change instruction letters to employers and credit payment redirection forms have also been developed to help consumers navigate the process.
