Important Information for New Clients
We will only carry out a full service on systems that meet minimum operational and safety standards. If your system does not meet these standards during our initial checks, we will complete an inspection only and provide guidance on any remedial steps required before a full service can be safely performed. This ensures the long‑term protection of your system and the safety of our engineers.

Most manufacturers recommend an annual service to keep your heat pump running efficiently. Regular servicing helps maintain performance, reduce energy costs, and extend the lifespan of your system.
Yes. While solar panels require very little maintenance, an annual system check ensures your inverter, cabling, and safety systems are working correctly. Catching small issues early helps avoid costly downtime later.
A service usually involves a full condition inspection, system health check, performance review, and technical support for your solar and battery. At OHM Energy, we also advise whether panel cleaning is needed for maximum efficiency.
Biomass systems work hard and can build up ash and residue. Annual servicing (or bi-annual if usage is heavy) keeps your system safe, efficient, and compliant with regulations.
Skipping servicing can mean lower efficiency, higher bills, unexpected breakdowns, and in some cases, voided warranties. Regular servicing is a small investment that protects your bigger investment.
Yes. We provide servicing for both our own installations and those completed by other installers. Our engineers are MCS certified and highly experienced across heat pump technology including Mitsubishi, Vaillant and Ideal Heating. They also have extensive experience in leading solar PV brands including AIKO and DMEGC.
Prices vary by system type and size. For example, heat pump servicing starts from £220 (inc. VAT), and solar PV servicing from £145 (inc. VAT). Full details are available on our service packages page.
