- Around 450,000 customers were affected by a recent failure in the banking application
- Lloyds has paid £139,000 in goodwill payments to more than 3,600 customers
- Treasury Committee wants two more updates after one and six months
As many as 447,936 banking customers may have had their data exposed, or seen transactions from other bankers, during a March 12, 2026, IT outage that affected those using Lloyds, Halifax and Bank of Scotland mobile apps, a report has confirmed.
The Treasury Committee’s new findings note that 114,182 users clicked on transactions that potentially allowed them to view sensitive information, such as account numbers and national insurance numbers.
This prompted the chairman of the Treasury Committee to pose “a number of questions” to the Lloyds group, which has now shared more information about the issue.

Lloyds ruling affected almost 450,000 banking app customers
A letter addressed by Executive Director of Consumer Relations Jasjyot Singh explained that the failure occurred between 03:28 and 08:08, caused by a software defect during an overnight system update. A fix was issued the same morning it happened.
While transaction amounts, dates, beneficiary information, account numbers, sort codes, NI numbers and references could have been exposed, it appears that this exposure required near-simultaneous access to the app by different users, so it depended on both the time of use and the failure in the first place.
We now know that no unauthorized transactions or account access occurred, and no financial losses have been identified to date. The risk of financial fraud has also been considered to be very low.
Separately, Lloyds has paid £139,000 in compensation to 3,625 customers in recognition of any hardship or inconvenience caused. Singh said this type of goodwill payment would be made under normal circumstances anyway for any inconvenience, and is not just a direct result of this particular technical issue.
The Treasury Commission has now asked the bank for new follow-up reports at one month and six months to ensure that the incident has been contained and has not affected customers.
