During the six-month deferral period, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is partially repaid within six months, the remaining interest will be adjusted to reflect the new balance. If the loan is fully repaid within the six-month deferral period, then no interest is payable, however, a £29 early settlement fee is payable in respect of repayments within these six months.

Following the six-month deferral period, Novuna Personal Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 18.9% APR on outstanding balances (backdated to the first date of the loan). Novuna Personal Finance will send a reminder letter approximately one month before the six-month deferral period is due to elapse.
