Barclays Bank is to offer one-to-one video services to some customers from next week, allowing users to speak securely to bank staff at any time of the day.
It claims the move as being a first for UK banking.
Premier account holders will be able to communicate with bank employees from their mobile phone, tablet or laptop.
Steven Cooper, CEO of personal banking at Barclays, said it would be a “watershed moment” in UK banking.
He said it would mean banks “interact with customers completely on their terms, rather than ours”.
The service will be rolled out to mortgage, business and wealth customers from early 2015.
It will then be made available to all retail customers.
Where possible, customers will be connected to a staff member they have already spoken to.
Mr Cooper added: “While many of our customers are increasingly using digital channels to complete routine transactions, for the important moments, you just can’t beat face-to-face conversations, yet traditional branch opening hours don’t always give customers that choice.”
