Services
Air Source Heat Pumps
Air source heat pumps extract heat from outdoor air to warm homes efficiently. They reduce carbon emissions by up to 70% compared to gas boilers and qualify for the Boiler Upgrade Scheme grant. Our MCS-certified engineers manage installations, ensuring compliance and long-term performance with a 15-20 year lifespan.
Underfloor Heating
Underfloor heating systems circulate warm water or use electric cables beneath floors for even heat distribution. They eliminate radiators, improve energy efficiency, and suit modern homes. Our engineers install water-based systems integrated with central heating, ensuring low maintenance and enhanced safety for families.
Solar PV Installation
Solar photovoltaic panels convert sunlight into electricity, reducing energy bills and grid reliance. We offer installations with battery storage options to save excess power for nighttime use. As MCS-certified installers, we ensure systems meet industry standards, enhancing property value and sustainability.
Gas & Oil Heating
Our Gas Safe and OFTEC-registered engineers provide boiler installations, repairs, and servicing for gas and oil systems. Services include landlord safety checks and maintenance contracts, ensuring compliance and efficiency. We offer extended warranties through partnerships with manufacturers like Vaillant.
EV Charging Points
Home EV charging points enable faster, safer charging than standard sockets. We install units compatible with hybrid and electric vehicles, reducing reliance on public chargers. Systems lower fuel costs and environmental impact, supporting sustainable transport solutions for homeowners.

Lee and Darren changed our old floor standing boiler over to a Vaillent boiler. They did a fantastic job. The space was a bit cramped to work in, We were very pleased with the final layout.
