An investigation has been launched after some customers using Lloyds, Halifax, and Bank of Scotland apps were able to see other users' transactions on their accounts.
A spokesperson for Lloyds Banking Group, which owns all three banks, apologised for the issue and said the incident had been resolved, according to BBC News.
Outage tracking website Downdetector.com saw a spike in reports of issues with the Halifax and Lloyds apps between 07:00 and 09:00.
Timeline of Events
A smaller spike was reported on the Bank of Scotland app, according to the website, with one woman reporting she was able to see the accounts of six different users on the Bank of Scotland app over a 20-minute period.
Those included transactions from a pub in Newcastle, 154 miles from her home in Kirkcaldy, Fife, fees for using one card abroad, and wage payments from a company based in England.
Customer Impact
The 55-year-old, who didn't want to be named, also reported being able to view benefits payments from the Department of Work and Pensions (DWP), which use the National Insurance numbers of recipients as a payment reference.
She said: "There were transactions from Waitrose, there isn't a Waitrose near us. I kept logging out and back in, and every time the details changed. I can see another person's bank account, he got paid £6,000 yesterday. Others, I can see their benefits payments, their National Insurance numbers, I can see where they work, almost their whole identity."
Previous Issues
Last year, banks including Lloyds said about 1.2 million people in the UK were affected by an outage in February 2025, with about 700,000 of those being Lloyds Banking Group customers.
The Lloyds Bank, Halifax, and Bank of Scotland apps were affected by technical issues during wider UK banking app outages on payday in January and February 2025.
Response and Investigation
The BBC has approached the UK's data watchdog, the Information Commissioner's Office (ICO), for comment, but Lloyds has not responded to questions about how many customers have been affected or whether it has contacted the ICO or any other UK regulators.
