If you have been given a gift voucher code for a scan, it will consist of five letters/numbers, such as PHJ7Y. (Please note this is different to a promo code, which provides a discount when booking a scan.)
If you have a gift voucher code, click here navigate to ‘Pricing/Book > Redeem Gift Voucher’ and enter the 5-character voucher code. It’s then easy from there. Make sure you confirm the booking and get a confirmation email (check your junk folder).
(If you have a promo code rather than a gift voucher, you should enter this at checkout before you make payment.)
