HSBC says it is to close 62 bank branches by the end of 2017.
Some will close in the summer while others will remain open until the end of the year.
The banking giant had already earmarked a total of 55 branches for closure, meaning a total of 117 will disappear in 2017. This is in addition to the 222 that were shut last year.
The bank says it's making the changes as more people are doing their day-to-day banking online, with the number of customers visiting its branches falling by half in the last five years.
Francesca McDonagh, HSBC's head of retail banking, said: "Fewer people are using branches. More than 90% of our interactions with customers are now through our digital channels - an increase from 80% last year."
Which? figures reveal that HSBC has closed over a quarter of its branches in the past two years, the most of any bank.
Around 180 staff are expected to lose their jobs as a result of the latest move, although HSBC says it hopes to redeploy affected workers.

You’ll automatically be eligible to bank at your nearest branch, so there’s no need to sign up or register.
The Post Office has 11,600 branches across the UK – find your nearest with the Post Office branch finder.
Or you always have the option to switch to a bank which has a branch near you.
Last week, Clydesdale and Yorkshire Banks announced 79 branch closures, while the Yorkshire Banking Group has completely done away with the Norwich & Peterborough (N&P) arm.
A total of 28 branches will be closing this year, all N&P current accounts will be closed and the brand will be abolished.
