Redirection of your order once despatched

We regret to say that we are unable to change the address or postcode on a parcel once it has been despatched. We therefore recommend that you check your delivery address and postcode carefully before completing the order as this will not be checked by us before despatch. We also recommend that orders are sent to an address where someone will be available all day to receive the parcel, e.g. a work address.

There may be delays to international deliveries due to the Coronoavirus crisis. Please see our update here for further information: Outside Update
