Heat Pumps Are Low-Maintenance — Not No-Maintenance
One of the quiet advantages of a heat pump is how little it asks of you. There is no combustion, no flue, no gas — so there is far less to go wrong than with a boiler. But like any heating system, an annual service keeps it running at peak efficiency and protects your warranty.
What an Annual Service Costs
An annual heat pump service typically costs broadly in line with a boiler service — usually somewhere in the region of £150 to £250 a year depending on the system and provider. Set against a heat pump's low running costs and 20-year-plus lifespan, it is a modest, predictable outlay.
Many manufacturers require evidence of annual servicing to keep their longer warranties valid, so it is worth budgeting for from the start.
What the Service Includes
A proper annual service checks the refrigerant circuit and pressures, inspects electrical connections, tests the controls and safety devices, confirms the system is still hitting its design flow temperatures, checks the water quality and system pressure, and cleans the outdoor unit's coil and clears the surrounding area.
The aim is to catch small issues early and confirm the system is still running as efficiently as the day it was commissioned.
Simple Things You Can Do Yourself
Between services, a few easy habits help. Keep the outdoor unit clear of leaves, snow and garden debris so air flows freely. Do not build sheds, fencing or planting tight around it. Keep an eye on system pressure and flag anything unusual — odd noises, error codes or a drop in performance — rather than ignoring it.
None of this is onerous, and it keeps efficiency high.
Good Design Reduces Maintenance
The best way to minimise maintenance is to install the system properly in the first place. Correct water quality to VDI 2035, a well-designed circuit, low flow temperatures and quality components all mean fewer problems over the system's life.

Frequently asked questions
How much does it cost to service a heat pump?
An annual heat pump service typically costs around £150 to £250, broadly in line with a boiler service. It keeps the system efficient and is often required to keep the manufacturer's longer warranty valid.
How often should a heat pump be serviced?
Once a year is standard, and manufacturers usually require annual servicing as a warranty condition. Between services you can keep the outdoor unit clear of debris and watch for any unusual noises, error codes or drops in performance.
Are heat pumps high-maintenance?
No. With no combustion, flue or gas, a heat pump has far less to go wrong than a boiler. Beyond a yearly service and keeping the outdoor unit clear, they are genuinely low-maintenance — especially when installed and commissioned properly.
