Will I be charged extra if I pay by credit card?

No, we don’t charge transaction or convenience fees.
If you choose to pay by debit or credit card a £1 pre-authorisation transaction will be charged to your card. This is just to verify your card, so there is no actual cost. Once your card has been verified it will disappear. With VISA debit cards, this transaction may be reapplied each day for up to 10 days before it is cleared.
