Services
Biomass Boilers
Biomass boilers burn wood pellets, chips or logs to provide heating for domestic and commercial properties. Our engineers service and install systems from leading manufacturers including ETA, Froling, and Viessmann. We stock spare parts for major brands and offer nationwide maintenance services, ensuring compliance with renewable energy incentive schemes.
Solar Photovoltaics
Solar PV systems convert sunlight into electricity using photovoltaic cells. We install roof-mounted and ground-mounted systems with inverters to convert DC to AC power. Our designs maximise energy production through optimal panel orientation and shading analysis, with options for battery storage integration to enhance self-consumption of generated electricity.
Battery Storage
Battery storage systems like Tesla Powerwall 2 store excess solar energy for later use. Our installations include lithium-ion batteries with integrated inverters for seamless power management. These systems reduce grid dependency and provide backup power during outages, with modular designs allowing future capacity expansion.
Combined Heat Power
Biomass CHP units generate electricity and heat simultaneously at 4.1p per kW. We install and maintain wood-fuelled gasifier systems suitable for large energy consumers. Our engineers provide technical support for Volter, Burkhardt, and Spanner units, with nationwide parts availability for rapid repairs and minimal downtime.
District Heating
District heating systems distribute heat through insulated pipe networks from central biomass boilers. We design schemes for commercial complexes, council buildings, and residential areas, with capabilities for heat distribution over 20-mile distances. Our Portmeirion project demonstrates expertise in large-scale renewable heat delivery.

Questions
What renewable energy systems qualify for RHI payments?
Biomass boilers, heat pumps, and solar thermal systems registered with Ofgem qualify for RHI payments, requiring annual servicing by certified engineers.
Do you service non-ESP installed systems?
Yes, we service most makes and models of biomass boilers, heat pumps, and solar PV systems regardless of original installer.
How does biomass CHP compare to solar PV?
CHP provides continuous base-load electricity at 4.1p/kW, while solar produces variable output depending on sunlight availability and seasonal factors.
Can solar panels work with battery storage?
Yes, our battery systems store excess solar energy for evening use, reducing grid dependency and maximising self-consumption of generated electricity.
What maintenance do biomass boilers require?
Annual servicing is required for RHI compliance, with regular ash removal and fuel system checks to maintain optimal performance and efficiency.
Do you offer site surveys?
Yes, we conduct desktop and on-site surveys to assess property suitability for renewable energy installations, including shading analysis and system design.
