Lloyds Banking Group Reports Additional 80,508 Customers Affected by March IT Glitch

Lloyds Banking Group reported that an additional 80,508 customers may have had their financial details exposed due to an IT glitch on March 12, 2026. This brings the total number of potentially affected individuals to more than 500,000. The glitch initially affected 446,915 customers across Lloyds, Halifax, and Bank of Scotland, who either viewed other people's transactions or had their own data shared.

The newly identified group consists of joint account holders linked to the initially affected customers. These individuals did not log into the banking app during the glitch, but their transaction details could have been visible. The bank issued alerts on the app home screen to these 80,508 joint account holders, with some exceptions based on customer circumstances.

Payments Lloyds Banking Group has paid £201,000 to 5,250 people affected by the incident. It has also provided an additional £62,000 in goodwill payments to 1,625 individuals since March 24, 2026. These goodwill payments address distress and inconvenience in individual cases where there was a direct impact.

The bank revised the initial number of affected customers who logged into the app to 446,915, down from 447,936 due to duplication. It also reported that 107,937 people clicked on visible transactions from others, lower than the initial estimate of 114,182.

Those who clicked may have seen detailed information such as account details, national insurance numbers, and payment references.

and Aftermath Lloyds Banking Group

stated that it has not observed an increase in daily fraud levels against the affected customers since the March 12, 2026, incident. Personal data of individuals who are not customers of the group was also visible, but no complaints from customers of other banks have been received.

The bank has not identified any customers who suffered financial loss from the incident and has not made compensation payments on that basis.

“We also issued an alert on the app home screen to these 80,508 joint account holders, with a small number of exceptions based on particular customer circumstances. In notifying these customers, our focus has been on providing reassurance and support.”

The incident resulted from a software defect during an overnight IT update, as the bank reported last month. The group provided this information in a letter to the Treasury Committee. No further incidents or complaints related to non-group customers have been noted.
