No, unfortunately it is not possible for us to amend delivery or collection addresses on placed orders.
That’s why we advise you to regularly make sure that all your address details are up-to-date.
If you change your delivery address in 'My Account' after you've made an order, your new address won’t apply until your next order.
If you have placed an order to an incorrect address, it will need to be cancelled. Please see how to request that here.
We are also unable to change the delivery type (standard, next day, collection, etc) once an order has been placed. If you have selected the wrong method, you may be able to cancel the order to re-order with the desired delivery method.
