Services
Air Source Heat Pumps
Air source heat pumps extract heat from outdoor air to warm homes efficiently. These low-carbon systems reduce reliance on fossil fuels and can save up to 70% in carbon emissions compared to gas boilers. With government grants covering up to 7,500 of installation costs, we handle the full process, ensuring MCS-compliant installations and long-term energy savings.
Gas & Oil Heating Systems
We install, repair, and service gas and oil boilers, including landlord safety checks. Our Gas Safe and OFTEC-registered engineers ensure systems operate safely and efficiently. All work includes a 12-month guarantee, with extended warranties available on Vaillant and Grant boilers for added peace of mind.
Underfloor Heating
Underfloor heating circulates warm water or uses electric cables beneath floors for even heat distribution. This energy-efficient solution eliminates radiators, improves aesthetics, and suits various floor types. Our experts design and install systems tailored to your home's requirements, ensuring minimal disruption and long-term comfort.
Solar Photovoltaics (PV)
Solar PV systems convert sunlight into electricity, reducing energy bills and grid dependency. We provide MCS-certified installations, optimising panel placement for maximum efficiency. Excess energy can be stored in batteries or sold back to the grid, enhancing sustainability and potential financial returns.
EV Charging Points
Home EV charging points offer faster, safer charging than standard sockets. We install compliant, efficient units compatible with hybrid and electric vehicles. This reduces reliance on public chargers, lowers fuel costs, and supports eco-friendly travel through renewable energy integration.
