An apology from Bupa after a direct debit fault resulted in some of its customers being double charged for their health insurance premiums.
The company has arranged refunds after approximately 50,000 of its four million health insurance customers were accidentally overcharged on 4 June due to a direct debit fault.
"All affected customers will be contacted directly and fully reimbursed today," said the insurer.
"Due to a system error, on 4 June some members' credit cards were accidentally charged twice for their health insurance premium," said Director of Customer Experience, Sally Damiani.
"We apologise for the mistake and for the inconvenience this has caused customers.
"This matter was taken very seriously. We are alerting affected customers but most importantly we have rectified the issue and all customers will have the amount refunded today."
