How Much Does a Heat Pump Service Cost?
| System | Annual Service Cost |
|---|---|
| Gas boiler | £80–£120 |
| Oil boiler | £100–£150 |
| Heat pump | £100–£200 |
| Heat pump (service plan) | £120–£180 |
The difference between heat pump and gas boiler servicing is £20–£80/year — not a significant factor in your decision. For the full cost picture, see our comprehensive guide.
What Is Included in a Service?
Outdoor Unit Checks
- Visual inspection for damage, corrosion, refrigerant leaks
- Airflow check — coil clear of debris
- Coil cleaning
- Fan inspection
- Condensate drain check
- Base and mountings stability
Indoor and System Checks
- System pressure
- Flow and return temperatures
- Electrical connections
- Controls and weather compensation settings
- Error log review
- Filter check and cleaning
Hot Water Cylinder Checks
- Stored water temperature (48–52°C)
- Pressure relief valve test
- Legionella cycle confirmation
How Often Does a Heat Pump Need Servicing?
Annual — same as a gas boiler. Best time: autumn (before heating season). The installation guide explains what proper commissioning and ongoing care involve.
Is a Service Legally Required?
Not legally mandated (unlike gas for landlords), but required by most manufacturers to maintain warranty (typically 5–10 years). A voided warranty on a compressor failure could cost £2,000+.
How to Find a Qualified Engineer
- Your installer — knows your system, offers continuity
- Manufacturer’s network — brand-specific training
- MCS installer database — search by postcode
- Independent engineers — check NVQ/City & Guilds and F-Gas certification
Our quotes service can connect you with engineers who offer servicing in your area.
What Happens If You Skip Servicing?
- Reduced efficiency: higher electricity bills
- Voided warranty: potentially £2,000+ for compressor repair
- Undetected faults: small issues become expensive problems
- Shortened lifespan: 15 years instead of 20–25

DIY Maintenance Between Services
- Keep outdoor unit clear (300mm clearance all sides)
- Check condensate drain not blocked
- Monitor electricity usage for sudden changes
- Check system pressure periodically
- Do NOT use a pressure washer on the evaporator coil
