As heat pump adoption continues to rise, so too do concerns over operational noise - especially in built-up areas.
Whether you're replacing an old system or planning a new install, finding a heat pump that won't disturb your home or your neighbours is more important than ever.
New data compiled from manufacturer specifications and standardised testing now reveals which models lead the way in quiet performance - with noise levels ranked and compared across the market by Quiet Mark, the independent sound certification body.
How the noise data was gathered
Every heat pump sold in the UK and EU must include an energy label detailing its sound power level (LwA) in decibels (dB), in accordance with international standards.
This sound power level represents the maximum noise the unit emits, measured under specific laboratory test conditions. It is not dependent on the distance from the unit and provides a reliable figure for product comparison.
Data in this list was collected from:
Manufacturer technical specifications
Energy labels available on official websites
Certifications based on sound testing
Publicly available performance data submitted under regulation
Only the lowest declared sound power level for each model is shown. Models are compared across categories but ranked solely by noise.

Why heat pump noise matters
Noise levels are now a regular part of planning considerations, especially in areas with close-proximity housing.
Models emitting lower decibel levels can help avoid disruption to neighbours and make installations simpler under local authority guidelines.
Poppy Szkiler, Quiet Mark CEO & Co-Founder said: "During the colder months, your heating can be on for long periods of the day. So making sure your main source of heat, whether that’s a heat pump or a boiler, isn’t going to disturb you when it comes on, can be essential."
This ranking allows consumers and professionals to evaluate, which models are most likely to meet acoustic expectations, regardless of brand reputation or other performance factors.
