We can now ship to Jersey and Guernsey. The cost is £19.99. However this will be offset somewhat by the fact that customers in the Channel Islands DO NOT pay VAT on our goods. The prices without the 20% VAT will be shown once you log into an account registered to a Channel Island address.

PLEASE NOTE: Whilst DPD Next Day is a 'Next Day' service, this is not guaranteed. Nor are the Royal Mail time frames guaranteed. 99% of parcels to mainland England do arrive on time, however sometimes parcels take longer, particularly if the delivery address is not in England. Also around public holidays the courier may need extra time to clear back logs. Please order in advance and allow plenty of time for delivery to cover any risk of delays. If your parcel has not arrived after 5 working days, then please feel free to get in touch with us.
