Services
Solar Thermal
Solar thermal systems capture sunlight to heat water for domestic and commercial use. Our designs integrate seamlessly with existing heating systems, reducing energy consumption by up to 60% annually. We specialise in in-roof installations and hybrid systems combining solar with biomass for year-round efficiency.
Biomass Systems
Carbon-neutral biomass boilers burn sustainably sourced wood pellets or chips to generate heat. Our systems achieve 95% efficiency, with options for automated pellet delivery and storage solutions. Ideal for properties without mains gas access seeking reduced heating costs.
Ground Source Heat Pumps
Ground source heat pumps extract stable underground temperatures to provide efficient heating and hot water. Our installations include horizontal/vertical ground arrays, delivering 4kW heat output per 1kW electricity used when paired with underfloor heating systems.
Air Source Heat Pumps
Air source heat pumps convert ambient air temperatures into heating and hot water. With 3-4kW output per 1kW electricity, these systems work optimally with oversized radiators or underfloor heating, providing consistent warmth at lower operating costs.
System Monitoring
Live monitoring solutions track energy production and system efficiency in real time. Our digital platforms provide usage analytics, maintenance alerts, and performance comparisons to ensure optimal renewable energy utilisation across solar, biomass, and heat pump installations.

Questions
What renewable energy systems do you install?
We specialise in solar thermal, biomass boilers, and ground/air source heat pumps for residential and commercial properties.
Can solar thermal systems provide central heating?
Yes, when combined with low-temperature underfloor heating or oversized radiators, solar thermal can supply significant space heating in spring and autumn.
Do you offer maintenance services?
Our systems are designed for minimal maintenance, but we provide servicing packages for biomass boilers and heat pump checks.
Are grants available for renewable installations?
We can advise on current UK government incentives like the Renewable Heat Incentive for eligible projects.
Can biomass systems operate automatically?
Modern pellet boilers feature automated fuel feeding and ash removal, requiring only weekly ash bin emptying and annual servicing.
What space is required for ground source heat pumps?
Typical installations need 10-12m deep boreholes or horizontal trenches equivalent to 1.5x property floor area for effective heat exchange.
