A technical glitch in the mobile apps and online banking platforms used by customers of Lloyds Banking Group allowed some users to view transaction details belonging to other account holders on Thursday morning.

The issue affected the group’s banking brands, Lloyds Bank, Halifax, and Bank of Scotland. and appeared early in the day, with a surge in reports between 7 a.m. and 9 a.m. GMT, according to outage tracker Downdetector. Customers said they were able to see unfamiliar payments, account balances, and full transaction histories that did not belong to them.

Some users reported viewing sensitive information, such as direct debit payments to the Driver and Vehicle Licensing Agency, that displayed vehicle registration numbers. Others said benefits payments from the Department for Work and Pensions revealed National Insurance numbers. Several customers also reported seeing large transaction totals in accounts, including roughly $1.02 million, about $347,000, around $32,000, and more than $1.28 million in combined transactions.

One Lloyds customer, Carl Lewis, said he could scroll through what appeared to be another person’s entire banking history. “The full history of the account that I could stroll through month by month, including direct debits to the DVLA where the car registration number is shown,” he said.

Halifax customer Helen Jermy said she saw records showing more than $1.28 million appearing as deposits in the account she viewed. Meanwhile, Bank of Scotland user Stephanie Flynn said she was alarmed after noticing around $32,000 in unfamiliar transactions, describing the experience as “a really scary experience.”

Some customers initially believed their own accounts had been hacked before realizing the information displayed appeared to belong to other users. One person said the experience left them feeling “almost traumatised.”

Lloyds Banking Group said it identified the problem quickly and resolved the error shortly after it was reported. In a statement posted on X, Lloyds Bank said the system had “incorrectly shown transaction information from some accounts to other customers in Internet Banking and the mobile app,” adding that the issue had been fixed.

The bank said no one gained unauthorized access to customer accounts and stated it is reviewing the incident to prevent a similar problem in the future. “Protecting our customers’ personal information and account security remains our priority,” the company said.

Regulators also responded to the incident. The Information Commissioner's Office said it was aware of the situation and would make inquiries, while the Financial Conduct Authority said it had contacted Lloyds to better understand what occurred and how the bank resolved the issue. The regulator said financial institutions are expected to safeguard customer data and respond quickly to service disruptions.

The incident follows earlier outages affecting Lloyds customers, including disruptions in January and February 2025 that temporarily prevented hundreds of thousands of users from accessing their transaction information.

Data compiled by lawmakers on the Treasury Committee shows that at least 158 banking IT failures occurred across the United Kingdom between January 2023 and February 2025.

Lloyds Banking Group, one of the country’s largest banking institutions with more than 30 million customers, has not said how many accounts were affected by Thursday’s glitch or whether any information was stored or misused outside the bank’s systems. Some customers have expressed concern about the safety of their personal information as digital banking continues to expand.
