Many banks and lenders implied or stated that taking out payment protection insurance (PPI) was compulsory to be approved for loans or mortgages, even though PPI was optional. Salespeople often did not inform customers about the cooling off period or that PPI was not required. Customers who were pressured into believing the application could not proceed without purchasing PPI, or who bought PPI after January 14, 2005 and were told it was strongly recommended, may have grounds for a PPI refund claim if they were not provided documents outlining why the policy was suitable.
