MPs seek answers from Lloyds over app glitch that exposed customer data

In a letter to the giant banking group, Treasury Committee chair Dame Meg Hillier says the incident appears to be an “alarming breach of confidentiality” and seeks further clarity on what happened.

In what the group called a technical glitch, users logging in to Lloyds, Halifax, and Bank of Scotland apps could see other people’s account details, including names, sort codes, spending histories back to December, and unfamiliar transactions.

In the letter, Hillier asks for information such as the number of affected customers, expected compensation payouts, the nature of the information which became visible, and what caused the issue.

Lloyds has apologised to affected customers but insisted that “there was no issue with account security”

In March 2025, the Treasury Committee published data showing that nine of the top banks and building societies operating in the UK accumulated at least 803 hours, the equivalent of more than 33 days, of unplanned tech and systems outages in the previous two years.
