Lloyds TSB is understood to have suffered a service interruption denying customers access to their online banking accounts this morning.

The problems appear to have lasted for just over an hour, with the bank’s customer service Twitter feed advising customers that normal service had resumed at 11:00 BST.

Some of the customers affected were staff at MoneySavingExpert.com, which said that some members of the team had tried to access their Lloyds account online at 9:45 BST, only to be met with the message: “We’re sorry but internet banking is currently unavailable. Please try again later.”

A spokesperson for the bank said: “For a short period, some of our customers experienced a slower service than normal when accessing their accounts.

Lloyds Banking customers were last affected by a technical problem in February, when customers were unable to make payments due to problems with the bank’s faster payments service.
