Santander customers were unable to access their bank accounts online for what seemed to be several hours on Friday.
The bank said on Twitter that there were problems with online banking, though some users seemed still able to access the app.
“We are currently experiencing issues with customers logging in to Online Banking,” Santander said in a tweet.
“Our team are working hard to resolve this as soon as possible. If you do need to log in, please try again later.”
Reports from users on Twitter suggest that the outage may have been running since around 9am on Friday morning, while Santander made its statement at about 1pm.
The outage comes on the last Friday of the month as Britons are preparing for the bank holiday weekend.
Santander has been contacted for further comment.
