Clivet says its Edge Pro air-source heat pump range has received Quiet Mark certification following laboratory testing and assessment by the programme’s acoustic board. The range’s design features include a compressor enclosure, larger, slower-running fans and vibration damping; Clivet reports sound levels up to 10 dB(A) below those of previous generations.
Quiet Mark has certified Clivet’s Edge Pro air-source heat pump range after laboratory testing and review by its acoustic assessment and verification board, according to a report by Cooling Post. The award gives buyers an independent noise-related assessment to consult when comparing heat pumps, while Clivet says the range produces sound levels up to 10 dB(A) lower than previous generations.
The certification applies across the Edge Pro range. Quiet Mark is an independent certification programme associated with the UK’s Noise Abatement Society. Its assessment compares heat pumps on a like-for-like basis, considering units of comparable sizes rather than treating all heat pumps as one category. The source report says the award followed laboratory testing and assessment by Quiet Mark’s acoustic assessment and verification board.
Clivet attributes the range’s acoustic performance to several design features: a silent-box around the compressor, larger fans that can run at lower rotational speeds, and a structure designed to damp vibration. The reported reduction of up to 10 dB(A) is a comparison with previous generations; the source does not give specific sound readings for each model or operating condition.
The cited Edge Pro models, numbered 2.1 to 8.1, are listed as offering A+++ heating efficiency at a 35°C water temperature and producing water at temperatures up to 80°C. The report gives heating capacities of 4.1 kW to 15.5 kW and cooling capacities of 4.5 kW to 15 kW. These are product specifications in the source report, rather than findings established by the Quiet Mark certification itself.
Noise Ratings for Heat Pump Buyers
Heat pump noise can affect where outdoor units are installed and how they are experienced by people inside a home and nearby. A certification based on acoustic assessment can offer another point of comparison for homeowners, installers and specifiers considering equipment alongside capacity and efficiency. Quiet Mark says its approach compares similarly sized units, which matters because noise comparisons can be misleading if products of different sizes or output classes are treated as equivalent.
The award does not, by itself, establish that every Edge Pro model will be quiet in every installation. Actual sound at a property may depend on the selected unit, its operating conditions, placement and surroundings. Buyers and installers still need model-specific acoustic information and site planning; the certification is a useful signal, not a substitute for those checks.

How Quiet Mark Assesses Heat Pumps
Quiet Mark describes itself as an independent certification programme associated with the Noise Abatement Society. Its stated purpose is to identify and certify quiet, high-performance products and building materials. For heat pumps, the programme compares products of comparable sizes rather than ranking every unit in a single category.
In this case, the report describes a process involving laboratory testing and review by Quiet Mark’s acoustic assessment and verification board. It does not provide the test protocol, model-by-model results or the date the certification was issued. The reported award is for the Edge Pro range, while the product specifications in the report refer to models 2.1 through 8.1.
“The range has achieved sound levels up to 10dB(A) lower than previous generations.”

Model-Level Noise Results Not Published
The available report does not state the certification date, publish model-by-model sound readings, or describe the laboratory conditions and operating settings used for the assessment. It is also unclear whether the “up to 10 dB(A)” comparison applies uniformly across the range or only to particular models or conditions. No direct statement from Quiet Mark or Clivet is included in the supplied material beyond the claims reported by Cooling Post.
The report does not explain how the certification should be interpreted for a specific property, where installation layout and surroundings can affect the experience of noise. Readers should not treat the range-wide award as a guarantee of a particular sound level at a given home.
Check Specifications Before Installation
People considering an Edge Pro unit can compare the relevant model’s published sound data, heating and cooling capacity, and operating requirements with their property’s needs. Installers and specifiers can use the Quiet Mark award as one selection point, while checking the model-specific acoustic information and proposed outdoor-unit location. Further detail on test conditions, exact readings and certification timing would help clarify how the result applies across the range; none is provided in the source report.
Key Questions
Which Clivet heat pumps received Quiet Mark certification?
The award covers Clivet’s Edge Pro air-source heat pump range, according to the Cooling Post report. It does not identify separate certification results for individual models.
What does Quiet Mark certification mean in this report?
Quiet Mark says it assesses products through laboratory testing and acoustic review. For heat pumps, the programme compares units of comparable sizes, rather than treating all products as one category.
How much quieter does Clivet say Edge Pro is?
The report says the range achieves sound levels up to 10 dB(A) lower than previous generations. It does not provide model-specific readings or the conditions behind that comparison.
What design features are cited for the noise reduction?
The cited features are a silent-box around the compressor, larger fans designed to run at lower rotational speeds, and a vibration-damping structure.
What are the listed Edge Pro capacities and efficiency?
For models 2.1 to 8.1, the report lists heating capacity from 4.1 kW to 15.5 kW, cooling capacity from 4.5 kW to 15 kW, A+++ heating efficiency at 35°C, and water temperatures up to 80°C.
