Buy a heat pump today
An air source heat pump system keeps your home cosy and your energy bills in check, and although they’re low-maintenance they still require regular servicing. Here at Hive, we’ll run you through all you need to know about heat pump maintenance, explaining what to expect when the engineer arrives, how often you should book a service, and the simple steps you can take to keep your systems performing between visits. Find out more below.
Key takeaways on heat pump maintenance
- Book an air source heat pump service every 12 months; add an initial check after install and consider more frequent visits in coastal or high pollution areas.
- Servicing could potentially help save money in the long-term, reduces energy use, extends lifespan, and helps keep your warranty valid.
- A standard visit covers visual inspection, performance checks, diagnostics, leak checks, electrical safety tests, and component cleaning.
- Expect costs of around £200 in the UK, but refrigerant or parts will cost extra. Always choose an accredited engineer and get an itemised quote.
- Between visits, clear debris, clean or replace filters every 1–3 months, keep vents unobstructed, and schedule a service before heating season.
How often do air source heat pumps need servicing?
For most homeowners, an annual service is the sweet spot for keeping their air source heat pump in prime condition. This will give your heat pump the chance to get cleaned up, checked over, and optimised for peak performance. However, some situations might call for more frequent attention. If your home is in a coastal area where salt spray is an issue, or if you're in a high-pollution urban zone, your heat pump might benefit from a more regular service. Similarly, newly installed systems also need an initial check-up after a few months to ensure everything's settled in properly.
Regardless of where you live and how old your heat pump is, you should always follow the manufacturer guidelines for warranty-related servicing, and don't hesitate to ask your installer about a tailored maintenance schedule that suits your specific model and location.

Could potentially save you money over time
Regular servicing is a very cost-effective strategy for maintaining your heating system. By addressing small issues early, you could potentially avoid expensive breakdowns and emergency repairs. Likewise, efficient operation resulting from proper maintenance could also lead to lower energy consumption, reducing your overall utility costs.
Not only that, but routine check-ups help to preserve your system's warranty, potentially saving you from costly out-of-pocket repairs. Over time, the investment in regular servicing often pays for itself through improved efficiency and avoided major repairs.
Reduces energy consumption
A well-maintained heat pump operates at peak efficiency, consuming less energy to produce the same heat output as a gas boiler. During a typical service, technicians will clean the main components, check refrigerant levels, and optimise system settings. These actions then ensure your heat pump doesn't have to work harder than necessary, reducing its energy demand. By minimising energy waste, you could not only lower your bills but also reduce your home's carbon footprint, which is a win-win!
Enhanced comfort
A serviced heat pump isn't just about efficiency; it's about comfort too. Regular maintenance ensures your system maintains stable temperatures throughout your home, eliminating any cold spots or temperature fluctuations. During a service, engineers check and calibrate sensors and controls, ensuring your heat pump responds accurately to your needs.
Increased lifespan
Regular check-ups and maintenance can significantly extend your system's life, potentially adding years to its service. By reducing wear and tear on components, addressing small issues before they escalate, and ensuring everything's running as it should, you're giving your heat pump the best chance at a long, productive life. It's also not uncommon for well-maintained heat pumps to outlast their expected lifespan by several years.
What’s included in an air source heat pump service?
A typical air source heat pump service includes several key checks and procedures to make sure your system is running efficiently and safely. Here's what you can expect:
- Overall visual inspection
- Temperature performance checks
- System diagnostics and visual assessment
- Leak inspection of heating pipework
- Internal component cleaning
- Electrical safety tests
- Advice on system settings and usage
How much does a heat pump service cost?
The cost of servicing an air source heat pump varies based on factors like location, system complexity, and the scope of work. Some services cover only the outdoor unit, while others include both indoor and outdoor components. Additional tasks, such as refrigerant top-ups or part replacements, typically incur extra charges. That said, according to British Gas, an annual boiler service in the UK usually costs around £100, while a heat pump service costs nearer £200.
While it's tempting to choose based solely on price, remember that a thorough service by a qualified professional is an investment in your system's longevity and efficiency. Always ensure your chosen engineer is accredited for heat pump work and request a detailed quote before booking.

How can I help to maintain an air source heat pump?
In between your annual servicing, there are several steps you can do yourself to maintain your heat pump:
- Keep the outdoor unit free from leaves, snow and other debris
- Regularly inspect and clean or replace filters (usually every 1-3 months)
- Be alert for unusual noises or changes in performance
- Monitor your energy bills for unexpected increases
- Use your thermostat judiciously, avoiding sudden large temperature changes
- Arrange your annual professional service before the heating season begins
- Ensure indoor vents and radiators remain unobstructed for even heat distribution
- Consider using a protective cover for the outdoor unit during extreme weather
