Many report that they’ve been locked out of their bank accounts. TSB has had numerous IT issues and outages since a bodged IT upgrade in 2018.

One Twitter used Tweeted: Anyone else having trouble getting into the @TSB app? I keep getting the message ‘we weren’t able to do that, bad request’ message come up.”

Other Tweets from disgruntled customers included: “@TSB online banking goes down more than Neymar in the box” and “Not again. This is getting to be a regular occurrence. Think it’s time to find another bank.”

TSB’s website service status page admitted to ‘intermittent’ problems with the bank’s mobile app and internet banking.

@TSB Tweeted: “We’re aware some customers are currently experiencing problems across our mobile app and internet banking. We’re working to solve this as soon as possible and apologise for any inconvenience caused.”

According to DownDetector.co.uk, the first problems with TSB were reported about 11.34am this morning, with reports reaching 1,358 within an hour.

One TSB customer posted the following on DownDetector: “I’m disgusted at TSB it’s been like this since 8am and 6 hours on still nothing! Can’t access any funds or transfer any money to and from accounts. This is the 3rd time in 4 months and sometimes it’s been like this for over a day! Now opening a new account elsewhere as we speak and soon as it’s all up and running I’m closing it down!”

TSB has been plagued by IT issues since 2018 after an IT upgrade left up to 1.9 million customers locked out of their accounts. The problems went on for several weeks with customers also unable to contact the bank by phone.

The fiasco cost TSB a total of £330m for customer compensation, fraud losses and other expenses.

The bank’s online banking and mobile app last went down in October 2020.

A statement from TSB said: “We’re aware some customers are currently experiencing problems across our mobile app and internet banking. We’re working to solve this as soon as possible and apologise for any inconvenience caused.”
