    National Boiler Spares are part of Heating Trade Supplies Group, a leading boiler spare parts company who delivers quality boiler parts at competitive prices.

    Our aim is to become your go-to choice for all your boiler spares. We offer a massive range of brand new, fully compatible, and remanufactured boiler parts. As the only company to hold BSI Kitemark for remanufacturing in the UK, our PCBs, diverter valves, and fans have been independently and repeatedly tested by BSI experts to ensure the quality and performance of our products meet that of a newly manufactured product. All our reconditioned products come with a 1-year warranty. We also remanufacture pumps, heat exchangers, and other parts.

    Our sustainable approach to the circular economy has dramatically reduced carbon emissions. Over the last 5 years, we have reconditioned over 70,000 PCBs and over 40,000 fans, in turn preventing the emission of 3,865,000 kg of CO2 into the environment.
