Santander has announced plans to close 111 branches across the country due to the shift to mobile and online banking.
The bank said it had taken the decision because fewer customers were choosing to bank in branch.
About 840 staff will be affected by the closures, although Santander promised to try to find them other jobs within the business.
Santander said the reduction in branch visits was a long-term trend that had been accelerated by the pandemic.
"Branch usage by customers has fallen considerably over recent years so we have made the difficult decision to consolidate our presence in areas where we have multiple branches relatively close together," said Adam Bishop, head of branches at Santander.
The move will reduce Santander's High Street presence to 452 branches.
But the bank said the majority of closing branches were within three miles of another Santander branch. The furthest is five miles, it said.
"All are within half a mile of at least two free-to-use ATMs and one mile of the nearest Post Office," it added.
