Barclays (LON: BARC) online banking has been restored after customers were unable to access their accounts using online banking.

The online banking was down between 10.45am and 5pm on Thursday, where customers saw the message: “5 – Sorry – Barclays Online Banking is currently unavailable”.

Angry customers took to Twitter to express frustration. One person tweeted: “@BarclaysUK Pensioners are going without food … some of us can’t pay our rent … because of no access to our Barclays accounts. Corporate banking has ruined Barclays. How do you intend to compensate yr customers? When will the system be up and running? The only bank where it happens.”

The bank released a statement on the website, which said: “We’re sorry if you’re unable to access online banking, telephone banking, or use some parts of our app. You can still check your balance and use most features in the app. Our teams are working to fix the problem … Thanks for your patience.”

Following the bank’s glitch, the group added: “We’re very sorry about the technical problems our customers have experienced today. Everything is now back up and running and we’re really grateful for customers bearing with us.”

Tashema Jackson, from uSwitch.com, advised Barclays customers and said: “If you think you’re facing a loss due to an unexpected online banking failure you can lodge a complaint with your bank for any financial damages incurred as a result of the disruption.”

“If you don’t believe you complaint has been dealt with appropriately by your bank you can take your case to the Financial Ombudsman for review.”

Barclays is the latest lender to face issues with its online banking. TSB customers were left without access to online banking for several weeks in April following an IT disaster.
