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.

The glitch meant they were able to view charges and payments made by other people.

A spokesperson for Lloyds Banking Group – which owns all three banks – apologised for the issue and said the incident had been resolved.

It is unclear exactly how many users have been affected.

Outage tracking website Downdetector.com saw a spike in reports of issues with the Halifax and Lloyds apps between 07:00 and 09:00.

A smaller spike was reported on the Bank of Scotland app, according to the website.

One woman told BBC News she was able to see the accounts of six different users on the Bank of Scotland app, including some National Insurance numbers, 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.

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.”

Last year, banks including Lloyds said about 1.2 million people in the UK were affected by an outage in February 2025.

About 700,000 of those were Lloyds Banking Group customers, its chief operating officer said in a letter to the chair of the Commons Treasury Committee.

A warning:

It is clear from social media that people have screenshotted erors on their banking app and put a picture up on various platforms.

If you have done that, please delete your post(s).

While you will have done this innocently, it could be considered a data breach. Some photos are clearly showing information from other people’s transactions.
