Cancel an online order right away
Under the Consumer Contracts Regulations your right to cancel an order starts the moment you place it and doesn't end until 48h have passed from the day your goods were delivered to you, your nominated neighbour or your dedicated safe place.
You should be given the ability to cancel an order at the point of sale. For example, this could be an online form or instructions to contact.
You can cancel an online order in writing, by phone or by email, and a cancellation form should also be made available although it’s sensible to stick with the process the retailer has set up - if it’s reasonable.
The retailer shouldn’t make cancelling an online order unnecessarily difficult. For example, you shouldn't need to call to get authorisation to return an item. You also shouldn't be told that items can’t be returned unless you’ve got a cancellation code.
Check the retailer's T&Cs and returns policy, as these will often set out the returns process, which will be especially relevant to you if the order is already in transit and you may need to return it once it’s been delivered.
If your order is in transit already, you probably won’t be able to cancel it before it reaches you.
But, remember that you still have the right to cancel the item for up to 48h after you’ve received it. Once you’ve confirmed with the retailer you’d like to cancel your order, you then have a further 48h to return it.
