TSB Bank, UK, faced a major outage that knocked out its mobile app and online banking services. Thousands of customers could not log in, check balances, or make payments.
The problems started around 9 a.m. UK time and lasted for hours. This happened on a busy payday, making things worse for people trying to pay bills or transfer money.
Customers reported error messages like “service temporarily unavailable” when trying to use the app. Some could not authorize online purchases or use features like Apple Pay.
Physical cards worked for in-store buys in many cases, but app-linked services failed. DownDetector showed a spike in reports, with over 1,000 complaints by afternoon. Most issues were with mobile banking (55%), mobile login (30%), and online banking (15%).
TSB quickly admitted the problem. A spokesperson said, “We’re aware some customers are experiencing issues with our Mobile Banking app and Internet Banking. We’re sorry for any inconvenience and are working to resolve this as soon as possible.”
They did not give a fix time, but urged users to check the status page or call support at 03459 758758, open from 8 a.m. to 10 p.m. on weekends.
Some found workarounds. A few accessed accounts via desktop browsers, though not everyone could. Others suggested trying phone banking or visiting branches, but with it being a bank holiday in parts of the UK, options were limited.
This is not TSB’s first tech glitch. The bank had similar outages in October 2024 and February 2025, raising questions about system reliability. In 2018, a major IT failure affected millions and led to fines. Experts say banks must invest more in digital infrastructure to handle peak times like paydays.
The outage highlights broader issues in UK banking. With more people relying on apps for daily finance, downtime can cause real hardship. Customers worried about missed payments or fraud risks during the blackout.
By late afternoon, some users reported partial recovery, but TSB had not confirmed full resolution. If affected, TSB advises using their help guide or contacting support. For complaints, visit their site.
This event underscores the need for robust banking tech. As digital services grow, so does the impact of failures. TSB customers hope for quick fixes and fewer repeats.
