Pallet Deliveries

Pallet deliveries are made between 8:00am and 6:00pm. We ask the delivery company to call approximately 1 hour before they are due to arrive.

All pallet deliveries are made 'kerbside'. This means your order will be left outside of your property at the nearest accessible location. Please note the pallet truck cannot travel over grass, gravel or steps and the driver will be unable to assist you in taking the goods into your property.

Please ensure you have let us know of any delivery restrictions that would prevent an 26 tonne lorry from unloading a pallet by tail lift outside your property. If a smaller vehicle is required, there will be an additional delivery charge.

Please ensure somebody is at the property on the agreed delivery day as all our deliveries require a signature. Failed palletised deliveries will unfortunately result in re-delivery charges. Some containers weight in excess of 25kg each and we recommend you have arranged help on the day of delivery if you need it.

Delivery to mainland UK only.
