Any extra payments you make will be applied as an overpayment against your account. Overpayments dont benefit from any interest rebates (a credit of interest) and they wont reduce your monthly contractual payments. However, they can be used as advance payment towards your future contractual monthly payments.If you'd like to make an additional payment in order to save on interest and reduce your monthly contractual payments (a partial settlement) then pleasecontact usso that we can set this up for you.
