  • Delivery Info
    Free Delivery

    Our "Free Delivery" is a one man service. The goods will arrive on a lorry that is about the size of a fire engine. (Please let us know in advance if you have restricted access.).

    The lorry has a tail lift that allows the driver to get the fireplace off the vehicle, the fireplace will be packed on a pallet and the driver will have a pallet truck.

    He'll be able wheel this as close as possible to your property, if you have a garage he'll be able to wheel it into there for you.

    The pallet truck can only be wheeled over a finished surface so it's not possible to wheel it over a gravelled drive nor is it possible to wheel up or down steps.

    The pallets are normally about a 1m wide so this is the minimum width gate they can fit through. Please note that the driver is not insured to unpack or carry the fireplace into your house.

    If the goods are showing 24hr or 48hr delivery then this is the quickest time we're able to deliver these items. You'll be asked to select your a delivery date when purchasing the goods.

    Please note that it is an all day delivery.
