How Much Does It Cost to Service a Heat Pump in the UK?

Heat pumps are quickly becoming one of the most popular ways to heat homes across the UK. With energy efficiency targets tightening and households eager to reduce carbon emissions, many people are switching to air source or ground source heat pumps. But, like any heating system, a heat pump needs regular servicing to keep it running smoothly and efficiently. One of the first questions homeowners ask is: how much does it cost to service a heat pump? Let’s break it down clearly and practically.

Why Servicing a Heat Pump Matters

A heat pump works hard all year round, transferring heat between your home and the outside environment. Over time, dust, debris, and wear can affect its performance. Regular servicing ensures:

• The system runs at maximum efficiency
• Electricity bills stay as low as possible
• The heat pump lasts longer
• Any potential issues are spotted early before they become costly repairs

Skipping an annual service can lead to reduced performance and higher running costs — not to mention the potential for voiding your manufacturer’s warranty.

Average Cost of Heat Pump Servicing in the UK

The cost of servicing a heat pump in the UK typically ranges between £150 and £250 per year, depending on the type of system and where you live.

Here’s a general breakdown:

Type of Heat Pump	Average Annual Service Cost	Notes
Air Source Heat Pump	£150 – £200	Most common and relatively simple to service
Ground Source Heat Pump	£200 – £300	More complex system with underground loops
Hybrid Heat Pump System	£180 – £250	Involves both a heat pump and traditional boiler setup

These prices usually cover a full inspection, cleaning of filters and coils, refrigerant checks, and system efficiency testing.

What’s Included in a Typical Heat Pump Service

A professional heat pump service in the UK generally includes:

1. Visual inspection – The engineer checks for any leaks, corrosion, or damage.
2. Filter cleaning and replacement – Dirty filters can block airflow and reduce efficiency.
3. Refrigerant check – Ensures the correct pressure levels and looks for leaks.
4. Electrical inspection – Verifies that all connections are safe and working properly.
5. Performance test – The engineer measures how efficiently the system is running.
6. Software updates or settings calibration – Optimises the system for maximum comfort and savings.

You’ll usually receive a service report afterwards, outlining the work carried out and any recommendations for maintenance or repairs.

Factors That Affect the Service Cost

The final price can vary depending on several factors:

• Location: Labour rates in London and the South East are often higher than in other parts of the UK.
• System age: Older heat pumps may require more thorough inspection or replacement parts.
• Service plan: Some installers offer annual service plans that can reduce the cost per visit.
• Accessibility: If your heat pump or its outdoor unit is difficult to reach, the service may take longer and cost more.

Is It Worth Having a Service Plan?

Many UK homeowners now choose to sign up for an annual heat pump service plan, which usually costs between £150 and £250 a year. These plans often include:

• One full service visit per year
• Priority callouts if your system breaks down
• Discounted rates for spare parts or repairs

This can be a smart option if you want to spread costs evenly and ensure your heat pump always gets attention from qualified engineers.

How Often Should You Service Your Heat Pump?

Most manufacturers recommend a service once a year. For air source systems that also provide cooling in the summer, a biannual check can be worthwhile — one before the heating season and one after.

Ground source systems, being less exposed to the elements, may need less frequent attention, but an annual inspection is still advisable to maintain efficiency and reliability.

DIY Maintenance Tips Between Services

While servicing must be done by a qualified professional, you can help keep your heat pump in good shape by doing a few simple things:

• Clean or replace air filters regularly (every 2–3 months)
• Keep outdoor units clear of leaves, dirt, and snow
• Check vents and ducts for blockages
• Monitor performance – if you notice reduced heating or unusual noises, call your installer

These small tasks can make a big difference in keeping your system efficient all year round.

Heat Pump Servicing vs Boiler Servicing Costs

If you’re used to a traditional gas boiler, you’ll be pleased to know that heat pumps generally cost similar or slightly less to service. While a typical boiler service might cost around £90 to £130, a heat pump service often includes more detailed checks and efficiency testing, which justifies the slightly higher cost. Plus, since heat pumps are more energy-efficient and environmentally friendly, the long-term savings easily balance out the maintenance expenses.

How to Find a Qualified Heat Pump Engineer

Always make sure your engineer is qualified or registered MCS-certified (Microgeneration Certification Scheme) and experienced with your specific brand of heat pump. Reputable installers and service providers can be found through:

• The MCS installer database ( It is helpful if you are seeking a government grant )
• The Renewable Energy Consumer Code (RECC) website
• Gas Safe Register
• Local recommendations or trusted trade platforms

Avoid unqualified engineers, as improper servicing can damage your system or void your warranty.

The Bottom Line

Servicing your heat pump is a small but essential investment in your home’s comfort and efficiency. Expect to pay between £150 and £250 per year, depending on the system type and your location in the UK. It’s well worth the cost — keeping your system running smoothly, cutting energy bills, and extending the lifespan of your equipment.

If you’ve recently installed a heat pump or are considering one, schedule a regular annual service with a qualified professional. It’s the best way to ensure your home stays warm, efficient, and eco-friendly all year long!
