The bank, which caters for charities and social enterprises, has appointed Amanda Brobyn as development manager to pioneer new services in the province.
Brobyn, a former business banking manager at Abbey, will attempt to increase the bank's client base in Northern Ireland.
A spokesman for the bank said not-for-profit organisations in the province needed more financial services.
"The social banking sector has very little presence in Northern Ireland," he said. "But there's no reason why that should be the case.
"Charity presence there is growing fast, with charities from the Republic of Ireland and from England both increasing their representation.
"We felt that this was a good opportunity for us. We have only a handful of clients there at present, but we're expecting to attract a lot of interest."
The move is part of a wider development plan by the bank, which will involve changes to its mission statement, lending rates and charity services.
