Privacy Scare for Millions: Lloyds, Halifax and BoS Apps Display Wrong Users' Transactions

March 12, 2026 – In a significant privacy scare for UK banking customers,

• Users of the mobile apps and online banking services for Lloyds Bank, Halifax, and Bank of Scotland reported seeing transactions and account details belonging to other people earlier today.

the incident

• Underscores ongoing challenges in digital banking security and data isolation.
• Serves as a reminder of the vulnerabilities in app-based banking systems, even among major institutions, and the importance of robust safeguards for personal financial data.

Lloyds Banking Group, which owns all three brands,

• Confirmed that a technical issue caused some customers to view incorrect transaction information from other accounts.
• Insists it was a technical glitch rather than a cyber-attack or external breach, has launched a full investigation to determine the root cause and prevent future occurrences.
• Has not reported any fraud or identity theft, as a direct result of today's issue.

In updates shared via their official channels, the group

• Described the incident as incorrectly displaying transaction data from some accounts to others in both the mobile apps and internet banking.
• They emphasised that the error has been fixed, with no indication of unauthorised access, hacking, or financial loss to customers. Balances remained correct for users, and the displayed rogue transactions were temporary artefacts of the glitch.

The bank quickly addressed the glitch, stating

• It lasted only a short time this morning.

A Lloyds Banking Group spokesperson issued an apology:

• “We’re sorry that some customers experienced an issue viewing transactions in the app for a short time this morning.
• The issue was quickly resolved, and we’re looking into what happened.”

The problem surfaced Thursday morning,

• Prompting a flood of complaints on social media as affected users spotted unfamiliar payments, charges, locations, and even references to personal details like shop names or wage deposits that clearly didn't match their own activity.
• One customer described seeing transactions from a pub in Newcastle despite living in Scotland. In contrast, others reported viewing details from accounts hundreds of miles away, including school fees and international card usage.
• Reports were inconsistent, with some users seeing hundreds of unrelated transactions, account sort codes, or partial personal identifiers upon logging in—often resolved after refreshing or relogging.
• Financial commentator Martin Lewis shared the reports on social media, asking followers whether they were affected and highlighting the widespread nature of the complaints.
• Many customers labelled it a "major data breach" due to the exposure of sensitive financial information, raising concerns about privacy and the potential for misuse if the glitch had persisted longer.

Customers who believe they were affected should monitor their accounts closely and contact the bank if they notice any irregularities.
