What does heat pump servicing involve?
Your air source heat pump service typically covers a thorough inspection of the outdoor unit including cleaning, checking for debris, and inspecting the fan, alongside refrigerant levels, pipework, and electrical connections.
Our engineers will also check internal components such as the expansion vessel, buffer tank, filters, and pumps, before running the system through its operating modes to verify temperatures and overall performance.
All findings are recorded and a full heat pump service report provided, this is important for maintaining your manufacturer warranty and keeping your system compliant.

Your questions answered
Common questions
If your question isn't listed, please reach out to us below.
How long does a heat pump service take?
A standard heat pump service takes around 60 to 90 minutes. It’s non-disruptive, with your engineer working on the outdoor unit and indoor components without needing to take your heating offline for any significant time.
How often does my heat pump need servicing?
Annual heat pump servicing is the standard recommendation across the industry, and it’s what most manufacturer warranties require.
How do I know if my heat pump needs servicing?
You don’t need to keep track yourself — as part of our aftercare, we’ll call you when your annual heat pump service is due. It’s one less thing to remember, and it keeps your manufacturer warranty protected without any extra effort on your part.
Do I need a heat pump service if it was recently installed?
Your first heat pump service is due one year after installation, to maintain peak efficiency and keep your manufacturer warranty valid. After that, annual servicing keeps your system protected and running at its best.
How much does a heat pump service cost?
Heat pump servicing costs £216 per year, or from £18.99 per month with a flexible payment plan. This includes a full annual service from an MCS-certified engineer, helping protect your manufacturer warranty and keep your system running efficiently.
Who can service my heat pump?
Only an MCS-certified engineer, trained and qualified in air source heat pump servicing, should carry out the work. Any task involving the refrigerant circuit also legally requires F-Gas certification. Choosing a certified professional protects your manufacturer warranty and ensures the job is done safely and correctly.
Do heat pumps need regular maintenance?
No — apart from your annual service, there’s nothing else to worry about. We take care of it all, so you can enjoy reliable, efficient heating without the hassle of ongoing maintenance.
What heat pump maintenance can I do myself?
Nothing is required from you between services — we handle the technical side entirely. If you’d like to help keep things running smoothly, simply keeping the outdoor unit clear of leaves and debris is the only thing worth doing yourself.
When is the best time to book a heat pump service?
Anytime really, as long as it’s booked annually, timing is flexible. That said, we’ll call you when your service is due, so you never need to think about scheduling it yourself.
