Another 13 locations have been earmarked for shared banking hubs in areas where the last branch has closed.
A swathe of branch closures have raised concerns about access to cash for those who need it, and difficulties for small businesses trying to deposit takings.
Ten other areas were previously identified, but the doors have yet to open on any of their new hubs.
Ministers have prepared legislation to ensure people can access cash locally, while experts say hubs are not enough.
"Cash is disappearing at a frightening rate, and so are ATMs and branches and it is not acceptable to leave communities without access to cash," John Howells, chief executive of Link - which is the biggest interbank network in the UK - told BBC Radio 4's Today programme.
"There is real investment and effort going in by the banks now…But now that pace needs to be picked up," he added.
At these hubs, customers of any bank can access their accounts, deposit cash and cheques, and withdraw money at any time. Trickier enquiries are dealt with by a representative from one of each of the major banks who each visit once a week.
Among the 13 new proposed banking hub sites, four are in Scotland and, for the first time, one is in Northern Ireland, in Kilkeel.
They will be in Brechin in Angus, Forres in Moray, Carluke in Lanarkshire, Kirkcudbright in Dumfries and Galloway, Axminster in Devon, Barton-upon-Humber in Lincolnshire, Lutterworth in Leicestershire, Royal Wootton Bassett in Wiltshire, Cheadle in Staffordshire, Belper in Derbyshire, Maryport in Cumbria, Hornsea in Yorkshire, and also in Kilkeel.
Decline in cash use eases after pandemic slump
'A customer said we'd changed her life with bank hub'
The BBC visited a prototype shared banking hub in Rochford, Essex, and was told it had been "a lifeline" for many people living in the area after the last branch in town closed.
Running costs are the same as a small branch, but are shared between different banking groups that use it.
Natalie Ceeney, who chairs the Cash Action Group which is overseeing the project, said: "Cash still matters hugely to millions of people across the UK and with the cost-of-living crisis biting, more and more people are turning to cash as a way of budgeting effectively. Banking Hubs are an important part of the solution."
Wait to open
Each time a core banking service such as a cash machine or bank branch is closed, an assessment is carried out by Link - the organisation which currently oversees the UK's ATM network.
The review studies the cash needs of the community, such as how easy it is to travel to the nearest alternative service, as well as the demographics and vulnerability of local residents. The criteria are set by a group of banks and consumer representatives.
The latest locations have been identified as part of that work.
However, it can take months for these new hubs to open. As well as finding a suitable premise, often changes are needed to ensure it is fully accessible and secure enough for banking services.
There has been some criticism that services have not yet started in any of the previously-announced locations for banking hubs, apart from the two trial premises in Rochford and Cambuslang, in Scotland.
