Heat Pump Annual Maintenance

Heat pump annual maintenance is a planned service visit that checks your system is running safely, efficiently, and as designed. It helps reduce running costs, prevent avoidable faults, and keeps comfort levels consistent through the colder months.

More information

What your annual heat pump maintenance covers

A thorough service focuses on efficiency, reliability, and early fault detection. Your visit is tailored to the system type and how it’s used, but typically includes:

  • Visual inspection of the outdoor unit, clearances, mountings, and weathering
  • Cleaning and checks of key components such as filters, strainers, and condensate routes (where fitted)
  • Checks of heating water pressure, expansion vessel operation, and evidence of leaks or corrosion
  • Inspection of primary pipework, insulation, valves, and accessible joints
  • Review of temperatures and performance, including flow and return readings
  • Controls check: schedules, setpoints, weather compensation, and hot water settings
  • Basic electrical and safety checks on accessible connections and isolators
  • Identification of wear, incorrect settings, or system issues affecting efficiency
  • Clear service notes and practical recommendations for improvements

Who this service is best for

Annual maintenance is ideal if you want predictable heating performance and fewer surprises.

  • Homeowners who rely on a heat pump as their main heat source
  • Landlords who need dependable operation and a clear service record
  • Small commercial sites where downtime or comfort complaints are disruptive
  • Properties with mixed emitters (underfloor and radiators) where balancing and controls matter

What happens during the visit

The appointment starts with a few questions about comfort, noise, and hot water performance, plus any recent changes to the property or usage. The system is then inspected, tested, and fine-tuned where appropriate, with findings explained in plain language.

If adjustments are needed, these are made with efficiency and comfort in mind, not guesswork. Where parts are worn or performance is outside expected ranges, you’ll get clear options for the next step.

After the service: getting ongoing value

You’ll receive a summary of what was checked and any recommended actions, prioritised by urgency and likely impact. If remedial work is required, you can decide whether to book it in straight away or plan it around your schedule.

Regular maintenance also makes it easier to spot gradual changes in performance over time, so your heat pump continues to run at its best as seasons and household demand change.

Frequently Asked Questions

How often should a heat pump be serviced?
Most systems benefit from an annual maintenance visit to keep efficiency high and catch issues early. If your system runs heavily or serves a multi-occupancy property, more frequent checks can be sensible.
What’s the difference between maintenance and a repair call-out?
Maintenance is planned and focuses on checking, cleaning, testing, and optimisation before anything fails. A repair call-out is reactive and aimed at restoring heating or hot water after a fault or breakdown.
Will annual servicing help protect my heat pump warranty?
Many manufacturers expect regular servicing as part of warranty terms. If you have warranty documentation, it’s worth checking the servicing requirements and keeping a record of visits and any remedial work.
Do I need to turn the system off for the service?
Not usually, but the system may be switched off briefly to complete certain checks safely. You’ll be told what’s happening and when heating or hot water might be interrupted.
What if you find a fault or the system is running inefficiently?
You’ll be shown the findings and given clear recommendations, from simple setting changes to targeted repairs. If parts or further work are needed, you can approve next steps before anything proceeds.
