Underfloor Heating Design and Supply for the Trade

Our design and supply service is focused on delivering practical, performance-driven underfloor heating solutions that integrate seamlessly with contractor programmes and developer requirements across Cardiff and South Wales. We begin with a detailed consultation and site appraisal to understand the build type, floor constructions and heating strategy, then produce heat-loss calculations and computer-aided layouts that define pipe runs, manifold locations and zoning for optimal thermal comfort and efficiency. Designs are produced to suit low-temperature heat sources including air-source and ground-source heat pumps, and we specify components to match project longevity, warranty expectations and maintenance regimes.

Supply logistics are planned to align with phased construction schedules, minimising on-site storage and handling while maintaining full traceability of batches and parts. We manage staged deliveries to match fit-out sequences on large developments and provide just-in-time kits for individual apartments or houses to reduce waste and speed installation. All components supplied are from reputable manufacturers and come with product guarantees; we provide clear documentation on compatibility, installation tolerances and commissioning requirements to support quality-controlled handovers.

For contractors who prefer to use their own labour, we offer comprehensive on-site training, technical support and step-by-step installation guides to ensure installers meet specified performance standards. Training covers pipe laying, fixing techniques, manifold assembly, pressure testing, screeding protocols and commissioning procedures. Our installation support package includes periodic quality checks, commissioning oversight and final sign-off documentation so developers and site managers can be confident in delivery.

Project management is a core part of our offer. We coordinate with main contractors, M&E teams, tilers and flooring suppliers to resolve interface issues and keep programmes on track. Our team prepares risk assessments, method statements and installation sequences tailored to each site, and we maintain open communication channels to resolve queries quickly and minimise delays.

Post-installation we provide formal commissioning, balancing and control programming, plus comprehensive handover packs including wiring diagrams, commissioning certificates and maintenance advice. Optional aftercare packages are available to provide scheduled servicing and rapid response to any operational issues.

By combining rigorous design, reliable supply logistics and hands-on contractor support, GT Underfloor Heating delivers scalable, low-temperature heating systems that meet developer timelines, reduce client snag lists and perform efficiently for end users throughout Cardiff, the Valleys and the wider South Wales region.
