    Large Items

    This is where we are different than other mainstream plumbing and heating merchants. We use our own drivers and vans to deliver large items and this for you means that:

    • We take great care to make sure the items arrive at your door safely with no damages.
    • We offer continuous assistance throughout the dispatch, transit and delivery process. So we keep you informed and make sure you have all you need for your project. 
    • We can collect cash on delivery, after you have checked and are happy with the goods which you have received.
    • You will decide the best time for the delivery and our driver will inform you one hour before arriving.
    • Our drivers are also fully knowledgeable on the products they are transporting, so that you can ask them any question when they arrive.
