Downdector recorded a surge of over 4,000 reports of issues, affecting users of Lloyds Bank, Halifax, TSB, and Bank of Scotland. Customers took to social media, sharing screenshots of error messages and expressing frustration, particularly as the outage coincided with payday. Many were unable to access their accounts to make essential payments.

Lloyds Bank acknowledged the issue, stating, “We know some of our customers are having issues logging on to online banking and our app. We’re sorry for this and we’re working to have everything back to normal.”

TSB said: “We’re aware of industry-wide issues this morning, and that some of our customers are unable to log into our mobile app, and internet banking. We apologise for this and are working hard to resolve it.”

A Nationwide spokesperson said: “We’ve identified an issue that was causing a delay to some incoming and outgoing payments. We’re now processing the queued payments, although we ask customers to bear with us as we complete their transactions. There is no need for people to resend payments. We apologise for any inconvenience caused.

“Customers can continue to make faster payments, use their cards to pay for goods and services, access the internet bank and banking app and withdraw cash from ATMs.”

The incident follows a similar outage at Barclays in January, highlighting growing concerns about the reliability of mobile banking services.
