Redirection of your order once despatched

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.

European and International Delivery

International service suspended

Unfortunately international orders are temporarily suspended due to the impacts of Coronavirus and Brexit related regulations. We are working to restore normal service when we can - please email [email protected] if you would like an update when we resume international services.
