Barclays revealed details in a prospectus to raise £5.8bn
Barclays Bank is to refund at least 300,000 personal loan customers because it made mistakes on their paperwork.
Lending rules say that if mistakes are made in loan paperwork, all interest paid must be returned.
The errors date back to October 2008. The bank said it would contact the affected customers.
Barclays said it was now investigating whether similar mistakes had been made in other parts of the business such as Barclaycard.
The errors on statements and arrears notices were mentioned with the bank's annual results in February, when it reported that income from retail and business banking had "declined 4% to £1,086m primarily due to provisions taken to remedy historical interest charges incorrectly applied to customers".
More details were given on Monday in a prospectus that the bank put out as part of its attempts to raise £5.8bn in new capital from investors.
In a statement, Barclays said: "whilst no-one has been mis-sold to, customers are entitled to have their interest payments returned".
"No customer will pay more than they were ever contractually expected to."
