Non Mainland UK Delivery

You may see this option if your order partly or fully contains lithium batteries that are not contained within the item we are shipping. If your postcode is not part of the Mainland UK for postal purposes then we will determine the best way to send your item(s) and in some cases we may have to cancel the order or offer an alternative solution, this is because Royal Mail and couriers have strict rules regarding the transport of lithium batteries and in the case of couriers certain regions of the UK have increased shipping costs.
