Yes, it is possible to change your delivery address (and, if required, your telephone number for delivery). The delivery address can be changed on your service page. The telephone number can be changed under your contact details. It is important, however, that you make these changes before payment. This will then be transmitted to the supplier correctly and on time.
Please note: With a bankruptcy auction you can only change the home delivery address before the auction closes. This will not be possible afterwards, either on the service page or under your contact details.
