more remote locations can be longer because of the logistics involved. All storage heaters, except mini-bathroom storage heaters, are over the standard carriage weight of 30 kg. Carriage is calculated based on your postcode and the number of pallets that will be necessary to dispatch your order (e.g. the cost of delivering 4 storage heaters could well be the same cost as delivering 1 storage heater if it is possible to get 4 heaters of the size ordered onto one pallet). We work on a maximum weight of 500 kg per pallet, which will be delivered by lorry.
