Lloyds customers reportedly able to see other people's account information in banking app

The Chair of the Treasury Committee has written to Lloyds Banking Group about an IT glitch that affected some of its customers, the committee said on 17 March 2026¹. On Thursday 12 March, it was reported that some customers of Lloyds Banking Group were able to see information related to other people's accounts through their banking app¹.

In the letter, Dame Meg Hillier says the incident appears to be an "alarming breach of confidentiality" and seeks further clarity on what happened¹. The committee chair has requested information including the number of affected customers, expected compensation payouts and the nature of the information which became visible¹. None of those figures has been reported.

The committee has asked for further updates one month after Lloyds' first reply and again in six months' time¹. The letter itself has been published by the committee¹.

The questioning follows earlier committee work on bank IT failures. Last March, the committee found that nine of the top banks had accumulated at least 33 days' worth of outages over the preceding two years¹.

Why it matters for households

The incident concerns Lloyds Bank customers who use the group's mobile banking app, and it was reported on 12 March 2026¹. What has been reported is that some customers could see information related to other people's accounts; the committee has asked Lloyds how many customers were affected and what kind of information became visible, and those answers have not yet been given¹.

The committee has also asked about expected compensation payouts¹. No figure, eligibility test or timetable for any payment has been reported, and no compensation has been confirmed.

The letter sits within wider parliamentary scrutiny of how banks handle IT and service failures, following the committee's earlier finding that nine of the top banks had accumulated at least 33 days' worth of outages over two years¹. For households, the practical questions raised by the committee are the ones still unanswered: how many people were affected, what they were able to see, and whether any payment follows.

What happens next

Lloyds has been asked to reply to the committee's letter¹. Further updates have been requested one month after Lloyds' first reply and in six months' time¹. The committee has not said when it expects the first reply, and no date for publication of Lloyds' response has been reported.
