As air source heat pumps (ASHPs) become more popular across the UK in 2025, many homeowners are asking the same important question:
“Do air source heat pumps need servicing?”
The short answer is yes — and regular maintenance is the key to long-term savings, comfort, and efficiency. Even though Prisma Services doesn’t currently offer servicing, we’re committed to helping UK households make informed decisions about heating and renewable energy.
Whether you’re considering a new air source heat pump installation or already have one, this complete guide answers everything you need to know.
What Is an Air Source Heat Pump?
An air source heat pump works by extracting heat from the air outside (even in cold temperatures) and using it to warm your home and hot water. It’s a low-carbon, energy-efficient alternative to traditional gas boilers — and is heavily promoted under the UK’s Net Zero targets and ECO4 scheme.
Do Air Source Heat Pumps Need Servicing?
Yes. Like any heating system, air source heat pumps require annual servicing to ensure optimal performance. Here’s why:
- Dust and debris can block the external unit, reducing airflow and efficiency.
- Moving parts, refrigerant levels, and pressure systems need regular inspection.
- Small issues left untreated may lead to expensive repairs or performance drops.
According to energy experts, a well-serviced heat pump can last 15–20 years — potentially longer than many gas boilers.
What Does an Air Source Heat Pump Service Involve?
During a typical service, a qualified technician may:
- Clean the external fan unit
- Check refrigerant levels and pressure
- Inspect electrical connections and sensors
- Ensure correct airflow and filter performance
- Test the defrost cycle
- Examine insulation on pipes and ducts
Servicing also includes performance checks to ensure your system is operating within recommended efficiency ranges (SCOP).
How Much Does Servicing Cost?
In 2025, the average cost of a professional air source heat pump service in the UK ranges from:
🔧 £150 – £250 annually
Costs may vary based on:
- Property size
- Type of pump (monobloc vs split system)
- Location and engineer availability
Some installers offer servicing packages or warranties that include annual checks.
What Happens If You Don’t Service It?
Neglecting your heat pump may lead to:
- Lower efficiency and higher bills
- Increased wear and tear
- Voided warranties (most require yearly servicing)
- Reduced heating performance in winter
In the long run, regular maintenance pays off by extending the life of your system and ensuring maximum savings on your energy bills.
Are You Eligible for a Heat Pump Grant in 2025?
While servicing isn’t covered, the UK government offers generous funding for heat pump installations through:
ECO4 Scheme
Low-income households may qualify for a free air source heat pump grant under the ECO4, available across England, Scotland, and Wales.
Boiler Upgrade Scheme (BUS)
Homeowners can get £7,500 off a new heat pump if replacing an oil or gas boiler.
At Prisma Services, we help eligible UK households apply for these grants and get free or discounted systems — even if you don’t have gas central heating.
