When you take out a loan with Post Office Loans - powered by Lendable, a non-refundable loan fee is added to the loan amount. You do not pay this fee upfront, it is paid via the monthly instalments which are set out in the Terms of the Loan Agreement. The loan fee and interest due on this fee is taken into account in calculating the Annual Percentage Rate (APR). Your quote will detail exactly how much the loan fee is.
