The decline in branch use has accelerated so much since the pandemic, that some of the branches closing are now serving fewer than 250 customers a week.
Over nine in 10 transactions are now completed digitally, the bank stated.
Ms Uhi added: “Branches will continue to play an important role in day-to-day banking, while providing specialist face-to-face support in moments that matter.
“In addition to our branch network, customers can access services through the Post Office network, our Community Pop-ups and soon-to-come Banking Hubs, alongside Live Chat, social media and through telephone banking.
