If you don’t use all the money in your voucher at once, the remaining balance will remain there and can be used later. You don’t need to deposit the entire value of your voucher in one deposit, which gives you a lot of flexibility. Remember, however, that your Neosurf voucher has an expiry date that can vary from several days to a whole year. If you don’t use it by the expiry date, you will lose the money in your voucher.
