Boiler Repairs
Our Gas Safe engineers provide rapid boiler repairs for domestic and commercial properties. We diagnose and fix faults efficiently, minimising downtime and restoring heating systems to optimal performance. Available 24/7 with no call-out fees, ensuring urgent issues are resolved promptly.
Underfloor Heating
We design and install wet underfloor heating systems for new builds and renovations. Our energy-efficient solutions distribute heat evenly, reducing fuel bills by up to 40% compared to radiators. We handle full projects including floor screeding, ensuring seamless integration with property-specific requirements.
LPG Boiler Installation
We supply and install LPG boilers for properties off the mains gas grid. Our services include tank installation and supplier connections, using high-efficiency models from ATAG and Viessmann. Engineers hold Gas Safe and LPG-specific accreditations, ensuring safe and compliant installations.
Power Flushing
Our power flushing service removes sludge and debris from central heating systems using professional equipment. This restores efficiency, extends boiler lifespan, and improves radiator performance. We use infrared diagnostics to confirm blockages before treatment, ensuring targeted and effective maintenance.
Renewable Energy
We offer renewable heating solutions including solar thermal panels, air source heat pumps, and biomass boilers. Our installations comply with building regulations and optimise energy efficiency. Commercial clients benefit from tailored biomass systems, while residential properties gain from reduced carbon emissions and potential RHI eligibility.
