Underfloor Heating Service and Maintenance

Our service and maintenance offering ensures underfloor heating systems remain efficient, reliable and trouble free throughout their working life. Beyond routine inspections and flushing, we deliver a structured maintenance programme tailored to the system type, building use and warranty requirements, with options for single annual visits or multi-year contracts that include priority response and parts cover. Each visit begins with a comprehensive inspection of manifolds, pumps, valves, pipework and controls, followed by system flushing and inhibitor checks where required, pressure testing and circuit balancing to restore even heat distribution. We also verify thermostat programming, zone sequencing and boiler or heat pump integration to ensure the whole heating system operates as designed.

Our diagnostic capability uses flow and return temperature analysis, pressure trend monitoring and smart control interrogation to identify underperforming circuits or component degradation before they escalate into failures. When repairs are necessary we supply approved spare parts and carry out corrective work to industry standards, recording component changes and test results in a client-facing report. For larger developments and managed properties we provide batch reporting and asset registers so facilities teams can track performance, plan renewals and demonstrate compliance with warranty and maintenance obligations.

Planned maintenance reduces emergency call-outs and extends component life, delivering measurable savings through lower energy use and fewer disruptive repairs. We offer flexible scheduling to fit tenant and site constraints, including out-of-hours servicing for occupied properties and phased maintenance plans for multi-unit developments to minimise disruption. Our team liaises with site managers, building services contractors and resident representatives to coordinate access and ensure safe working practices.

Training and documentation are included with contract options. We provide handover packs, commissioning certificates and maintenance manuals, plus on-site training for facilities staff or contractor teams covering basic fault finding, thermostat operation and simple routine checks. For developers and large clients we can deliver bespoke service level agreements with agreed response times, billing terms and KPI reporting.

GT Underfloor Heating’s service and maintenance packages are delivered by experienced engineers led by Installation Director Graeme Gunning, combining practical installation knowledge with a preventive, data-led approach to aftercare. We serve Cardiff, the Valleys and the wider South Wales region, and tailor each plan to system age, floor type and occupancy to ensure long-term performance, occupant comfort and optimised running costs.
