Lloyds, Bank of Scotland and Halifax are to close 60 bank branches across the UK.
Parent company Lloyds Banking Group said the decision was made as the number of customers now using online banking reached an all-time high this year.
Lloyds says it now has 18.6 million regular online banking customers and over 15 million mobile app users. These have increased 12% and 27% respectively in the last two years.
