Many NatWest branches will extend their opening hours today and over the weekend to help customers affected by this week’s computer failure.
Although the underlying technical issue is believed to have been resolved, many customers are still having difficulty in accessing their accounts, and account balances are still not being updated properly overnight.
Although Wednesday night’s payments have now been processed, some of Thursday night’s payments are still not showing up on accounts.
Some customers are finding they are unable to access their salaries and others are unable to pay their bills on time.
In order to deal with the backlog, 1,000 NatWest branches will open until 19:00BST today, and branches normally open on Saturdays will stay open until 18:00.
Branches which usually open on Saturdays will also open on Sunday morning this weekend, from 09:00 to midday.
NatWest has apologised for the “unacceptable inconvenience” caused by the issues which have affected NatWest accounts and also some RBS and Ulster Bank accounts.
The bank has reassured customers that they will not lose any money as a result of the problems and emergency cash may be available to people who are struggling to meet their commitments as a result of the situation.
Anyone who is out of pocket as a result of the glitch should contact the bank as soon as possible.
The computer problems started following a software update on RBS’s payment processing system.
It is less than a month since Barclays and Santander were affected by online banking problems, with customers unable to access their bank accounts online.
HSBC customers also experienced difficulties at the end of May, as a result of a hardware glitch.
Some HSBC customers found they were unable to withdraw cash from ATMs and carry out debit card transactions.
