Payment protection insurance (PPI) is insurance that covers loan or credit card repayments if the person becomes unable to pay, such as due to illness. If someone believes their PPI policy was mis-sold, they should contact the lender to make a claim or get advice from PPI Claims Advice Line experts. PPI Claims Advice Line can help confused customers understand how to claim money owed from valid PPI policies sold by banks and lenders, and direct them to the process and regulations on their website.
