Keep Your Biomass and Solar PV Systems Running at Peak Performance At ESP Energy, we understand how important it is to keep your renewable energy systems operating efficiently and reliably. That’s why we offer expert servicing and maintenance for biomass boilers and solar PV systems across the UK. Our skilled engineers are trained in the repair and servicing of most major biomass boiler brands and solar PV technologies, helping both domestic and commercial clients avoid costly downtime, maintain performance, and stay compliant with incentive scheme requirements like the Renewable Heat Incentive (RHI).
If your biomass boiler or heat pump is registered under the Renewable Heat Incentive (RHI) scheme, you are required to have it serviced annually by a certified HETAS engineer to remain compliant with Ofgem regulations. Our certified engineers perform a full, compliant service and provide all the documentation required for RHI inspections. We also register the service with HETAS at no additional cost. If faults are identified or replacement parts are needed, we’ll quote, source, and repair with your approval using genuine, manufacturer-approved components. After every service, you’ll receive a full service report, ready for your RHI audit or records.
What’s Included in a Heat Pump Service: Our comprehensive heat pump service includes all essential checks: Visual inspection of indoor and outdoor units Inspection of pipework, insulation, and lagging Check for refrigerant leaks and pressure levels Inspection and cleaning of filters, coils, and airflow channels Cleaning of heat exchanger surfaces Test of system temperature sensors and ambient probes Check and recalibration of thermostats and room controls Testing of flow and return temperatures Electrical safety inspection of all system components Check of compressor, fans, and motor operation Verification of expansion vessel pressure Inspection of valves, pumps, and diverter valves Check and top-up of system fluid (for ground loops or glycol systems) Assessment of noise levels and vibration issues System pressure test and top-up if required Check for error codes, warning lights, and system alarms Full review of control settings and operational logic Cleaning of condensate drains and trays (for air source units) Issue of service report with performance notes and any recommendations
What’s Included in a Biomass Boiler Service: Our detailed servicing includes all mandatory HETAS checks: Grate and refractory condition Wear and tear to internal components Cleaning of combustion and mechanical parts Gaskets, seals, insulation, fire bricks Flue, chimney, gasket, fans, and fuel store inspection Heat exchanger and cleaning mechanism Sensors: flue gas, lambda, ignition, combustion control Pumps, valves (ESBE, pressure relief, 3-way, etc.) Safety checks and flue gas readings Burn-back flaps, filters, condensation drains, extraction systems Lubrication of mechanical elements Full boiler controls and system performance review
For Business Owners Switching to solar PV is a smart move for businesses looking to reduce operating costs and meet sustainability targets. By generating your own clean electricity on-site, you’ll significantly cut CO₂ emissions, reduce reliance on the grid, and demonstrate environmental leadership all while turning unused roof space into a revenue-generating asset through energy savings and export tariffs. For Homeowners Installing solar panels at home gives you greater energy independence, helping you become more self-sufficient while protecting yourself from rising electricity prices. By generating your own power and using it when you need it most, you’ll reduce your carbon footprint, lower your monthly bills, and gain real control over your household energy future.
