Services
Air Source Heat Pumps
We design and install air source heat pumps that convert ambient air into efficient heating solutions. These systems reduce energy bills by up to 70% compared to traditional methods, with three kilowatts of heat generated per kilowatt of electricity used. Ideal for homes and businesses seeking sustainable alternatives, our installations qualify for RHI payments and government loans.
Biomass Boilers
Our biomass boiler installations use organic materials like wood pellets to provide eco-friendly heating. Designed for properties off the gas grid, these systems offer significant cost savings and RHI income. We handle all aspects from planning to certification, ensuring compliance with safety and environmental standards.
Gas Safe Services
We provide gas boiler installations, servicing, and safety certifications for domestic and commercial clients. Our Gas Safe registered engineers ensure all work meets regulatory requirements, including landlord safety certificates and emergency repairs for uninterrupted heating.
Underfloor Heating
We install underfloor heating systems compatible with renewable energy sources. These systems offer even heat distribution and energy efficiency, suitable for new builds or retrofits. Our designs consider property size and insulation levels to optimise performance and client comfort.
RHI Compliance
We guide clients through Renewable Heat Incentive applications, ensuring systems meet eligibility criteria. Our support includes energy performance calculations, documentation preparation, and ongoing compliance advice to maximise financial returns from the RHI scheme.
