HSBC has apologised to customers after some were left locked out of their online banking on what is pay day for many workers.
Virgin Money and Nationwide are also reported to be experiencing issues with digital banking services on Friday.
HSBC UK said on the service status page of its website: “We’re really sorry that some customers are having issues accessing personal online and mobile banking.
“Our IT teams are working hard to get these services back to normal. You can still authorise online card purchases via SMS.”
Some customers took to X, formerly Twitter, to complain that they were unable to access their bank accounts online or on their mobile app.
Some pointed out that it was pay day for them and said they needed to access money to pay bills.
According to the website DownDetector, more than 7,000 problems were reported at about 8.45am.
The site also shows a spike in reports of outages for high street bank Virgin Money and building society Nationwide on Friday morning.
Virgin Money said on X that it was “aware of intermittent issues with accessing online banking and our app, which we’re working to resolve as quickly as possible”.
“Thanks for your patience while we restore the service,” it said.
It follows an earlier post alerting customers to “delays to payments both in and out of their Virgin Money account”, and asking people not to try again to make a payment if they had received an error message.
Speaking to the BBC, Nationwide said it was “aware of a third-party payments issue impacting some providers, including Nationwide”.
“This has unfortunately delayed a small number of payments, which we expect will be processed and paid later today,” it added.
