A technical glitch at Lloyds Banking Group allowed customers to see other people's account details, impacting customers of Lloyds Bank, Halifax, and Bank of Scotland during the morning of Thursday, March 12, 2026. According to Lloyds Banking Group, the issue was caused by a software defect from an overnight IT update, with up to 447,936 customers across its brands potentially seeing other people's transactions or having theirs seen by others. Up to 114,182 customers clicked to view transaction details and may have seen information about individual payments, according to reports. Lloyds stated there was no account security issue and no one had access to anyone else's account.
Lloyds Banking Group has made goodwill payments totaling just over £139,000 to some 3,625 customers, averaging around £40, according to multiple reports. Customers were offered payments of £25, £40, or £50 after complaining.
From March 24, all affected customers will be alerted in their app, as part of Lloyds' notification strategy to inform users about the incident.
Lloyds Banking Group is facing questions from the Treasury Committee after customers reported seeing others' transactions. Treasury Committee chair Dame Meg Hillier wrote to Lloyds requesting information on affected customers, compensation, and the nature of the information visible.
The Financial Conduct Authority (FCA) was in contact with Lloyds to understand and resolve the issue, according to multiple reports. The Information Commissioner's Office has confirmed it is making enquiries into the incident.
On 12 March, a limited number of customers using our app may have briefly seen transactions that weren't theirs due to an internal IT change.
A separate technical issue at NatWest delayed money transfers to and from 'pots,' affecting hundreds of customers, according to multiple reports. NatWest apologized and said the problem was caused by a delay with transfers, no one lost money, and balances will update shortly. Other brands in the NatWest group, RBS and Ulster Bank, were not affected, as confirmed by multiple reports.
The exact total number of customers affected by the Lloyds technical glitch remains unclear. Whether any fraudulent activity or identity theft resulted from the exposure of sensitive information during the Lloyds glitch is also unknown.
The specific technical root cause of the software defect in Lloyds' IT update that led to the data breach has not been publicly detailed. The full scope of compensation or regulatory penalties Lloyds Banking Group might face from authorities like the FCA or ICO remains uncertain.
How long the NatWest transfer delay issue persisted and whether any customers incurred overdraft fees or other financial impacts despite no funds being lost are unresolved aspects of that incident.
