Average Heat Pump Service Costs in the UK
An annual heat pump service in the UK typically costs between £100 and £200 for a standard residential air source heat pump. Prices vary based on your location, the engineer’s qualifications, whether a cover plan is in place, and the size and complexity of your system.
What’s Included in a Heat Pump Service?
A thorough annual heat pump service should include:
- Visual inspection of all components
- Cleaning or replacing air filters
- Checking refrigerant pressure levels
- Inspecting and cleaning the evaporator coil

Cost Breakdown by Type
Prices vary depending on the service type:
- Basic annual service: £100–£150
- Full comprehensive service: £150–£200
- Commercial ASHP service: £200–£400
- Ground source heat pump service: £180–£300

Is Annual Servicing Legally Required?
Unlike gas boilers, annual servicing is not a legal requirement for heat pumps. However, many manufacturers specify in their warranty conditions that the unit must be serviced annually by a qualified engineer to maintain warranty validity. Skipping services can void your warranty and reduce efficiency by 10–20%.
How to Get the Best Value
Consider taking out an annual cover plan, which typically costs £15–£25/month and includes the annual service plus callout cover for breakdowns. This gives budget certainty and ensures your system gets attention even if a fault develops between services.
