Heat pump servicing in London from £120+VAT. Annual service plans for air source heat pumps, all makes. Book your service.
Heat pump servicing in London is an annual inspection and performance check that protects efficiency, reliability and warranty records. Our air source heat pump service covers all major makes and starts from £120+VAT.
Heat pumps operate for long periods and depend on clean airflow, stable water circulation, sound electrical connections and accurate controls. Gradual changes are easy to miss because the system may keep running while consuming more electricity. Planned maintenance records these conditions before they become comfort problems or breakdowns.
We inspect accessible pipework, joints and coils for signs of leakage, review operating temperatures and assess the refrigeration circuit where the service scope and system type require it. Refrigerant handling is reserved for appropriately qualified engineers.
Terminals, isolators, protective devices, wiring and visible components are checked for security, heat damage and deterioration. Stored fault histories are reviewed before codes are cleared.
Dirty air filters, blocked outdoor coils and restricted water strainers reduce heat transfer. We inspect and clean serviceable items included in the visit, and identify components needing separate remedial work.
The outdoor coil, drainage route, temperature sensors and available operating data are checked for conditions that can interrupt effective defrosting or leave persistent ice around the unit.
We listen for abnormal operation and review available temperatures, current, runtime or performance data. These checks can identify stress caused by poor flow, control settings or refrigeration faults before complete failure.
System pressure, pumps, valves, flow temperatures, weather compensation, heating curves, hot-water settings and emitters are reviewed so the heat pump can deliver heat without excessive cycling or backup-heater use.
Warranty compliance: many manufacturers require evidence of maintenance at stated intervals. A dated service record supports that history, although owners must check whether their warranty requires a particular approved provider or checklist.
Efficiency: clean heat exchangers, unrestricted flow and suitable controls help the system transfer heat at lower compressor effort. Servicing can highlight settings that cause cycling, high flow temperatures or unnecessary immersion-heater use.
Longevity: loose connections, blocked strainers, low pressure, poor drainage and abnormal noise can be addressed before they place additional strain on pumps, fans, valves and the compressor.
Reliability: an annual visit before winter gives time to obtain parts or plan corrective work. It is more practical than discovering an avoidable fault during the coldest week of the year.
Annual service plans suit homeowners, landlords and small businesses that want a regular maintenance date and a consistent record for one system. Planned maintenance contracts are available for sites with several heat pumps, cylinders, fan coils or connected controls. The schedule can group visits, list the assets covered and record recommendations by unit.
We service Mitsubishi Ecodan, Daikin Altherma, Samsung EHS, Grant Aerona, NIBE and Vaillant equipment, along with many other established air source heat pump makes. Model-specific menus and service requirements differ, so please send the outdoor-unit model, cylinder details and previous service information when booking.
The Domestic Renewable Heat Incentive closed to new applicants in March 2022, but existing participants may still need to retain evidence that their eligible heating system remains in working order and is maintained appropriately during their tariff period. The Non-Domestic RHI also has continuing obligations for accredited installations.
You send the make, model and service history, tell us about comfort or energy-use concerns and provide clear access to the indoor and outdoor equipment.
The engineer checks the installation, safety, coils, drainage, filters, strainers, pumps, valves, visible wiring and controls, cleaning serviceable items included in the appointment.
The heat pump is observed under demand where conditions permit. Flow, temperatures, system pressure, controls, defrost behaviour and available diagnostic data are reviewed.
Weather compensation, heating curves, schedules and hot-water settings are checked for obvious conflicts with the property and emitter system. Changes are discussed rather than applied without context.
You receive a record of the service and a clear explanation of defects, monitoring points or separately priced repairs. Urgent safety or reliability issues are prioritised.
| Service | Price | Best for |
|---|---|---|
| Annual heat pump service | From £120+VAT | One domestic air source heat pump with safe standard access. |
| Multi-system service plan | Quoted | Landlords, commercial premises and sites with several assets. |
| Repairs found during service | Quoted separately | Parts, extended diagnostics and remedial work beyond routine servicing. |
Prices exclude VAT. Specialist access, multiple units and additional fault investigation are confirmed before booking or quoted after inspection.
Heat pump servicing in London starts from £120+VAT. The exact heat pump service cost depends on the system type, number of units, access, service history and whether additional fault investigation or remedial work is requested.
Most domestic air source heat pumps should be serviced once a year. Manufacturer warranty terms may set a specific interval, while heavily used commercial systems can benefit from more frequent planned maintenance. Always follow the schedule in your installation and warranty documents.
A service typically includes visual and safety checks, filters and strainers, coil and airflow inspection, electrical connections, controls, flow temperatures, system pressure, water flow, defrost operation, compressor performance indicators and a refrigerant-circuit assessment where appropriate.
Regular servicing can be a condition of manufacturer warranties. We record the visit and findings, but owners should check the exact terms, approved-servicer requirements and intervals stated by their manufacturer and installer because warranty rules differ between brands.
Yes. We service Mitsubishi Ecodan, Daikin Altherma, Samsung EHS, Grant Aerona, NIBE and Vaillant systems, as well as many other air source heat pump brands, subject to model information, safe access and manufacturer documentation.
