Clivet says its Edge Pro air-source heat pump range has received Quiet Mark certification following laboratory testing and review by the programme’s acoustic assessment board. The range includes models with heating capacities from 4.1 kW to 15.5 kW; further details about the testing results and certification criteria for individual models have not been provided in the source report.
Clivet’s Edge Pro air-source heat pump range has received Quiet Mark certification, following laboratory testing and an assessment by the programme’s acoustic assessment and verification board, Cooling Post reported. The certification addresses noise performance, an important consideration for households and installers choosing outdoor heating equipment.
Quiet Mark is an independent certification programme associated with the UK’s Noise Abatement Society. It identifies and certifies products and building materials that it assesses as quiet, while also considering performance. According to Cooling Post, the award applies across the Edge Pro range, rather than to only one model.
Clivet’s design includes a sound-insulating enclosure around the compressor, larger fans intended to operate at lower rotational speeds and a structure designed to damp vibration. The report says these features have helped the Edge Pro achieve sound levels up to 10 dB(A) lower than previous generations. That comparison is with earlier generations of the product; the report does not give absolute sound readings or specify the operating conditions for the comparison.
The reported range spans heating capacities of 4.1 kW to 15.5 kW and cooling capacities of 4.5 kW to 15 kW. Clivet’s models numbered 2.1 to 8.1 are listed as having A+++ heating efficiency at 35°C and the ability to produce water at temperatures up to 80°C. These are product specifications reported by Cooling Post, separate from the noise certification.
Noise Ratings Matter at Home
Heat pumps are commonly installed outside homes, so operating noise can affect residents and people nearby. Certification focused on acoustics may help buyers and installers compare noise performance alongside capacity, efficiency and suitability for a particular property. It does not, by itself, establish how loud a unit will seem in every installation: placement, surroundings and operating conditions can affect what people hear.
Quiet Mark’s approach, as described in the report, is to compare heat pumps on a like-for-like basis, taking account of units of comparable sizes instead of treating every heat pump as one category. That qualification matters because capacity and design differ across products. The award offers a signal that the range has been assessed under the programme, but buyers may still need model-specific sound data and installation advice to judge how a unit would perform at their home.

How the Edge Pro Was Assessed
The report says certification followed laboratory testing and review by Quiet Mark’s acoustic assessment and verification board. It does not describe the test protocol, identify the laboratory, or publish the results for each model. Quiet Mark is described as an independent programme associated with the Noise Abatement Society; the source does not state that the society itself carried out the testing.
Clivet attributes the range’s noise performance to three design elements: the compressor enclosure, larger fans operating at lower speeds and vibration damping. The reported reduction of up to 10 dB(A) is relative to previous generations, not a comparison against all competing products. Quiet Mark’s size-matched comparison method provides additional context for the award, but the report does not name competing units or provide comparative scores.
“The certification has been awarded across the Edge Pro range.”

Model-Level Noise Data Not Published
The available report does not include absolute sound-pressure or sound-power readings, results for individual models, or the conditions under which noise measurements were taken. It also does not give a date for the certification announcement or explain whether the award is subject to periodic retesting.
The stated reduction of up to 10 dB(A) is measured against previous generations, according to the report. It should not be read as a claim that every Edge Pro model is quieter than every competing heat pump, or that the same reduction will be perceived at every installation. Further comparisons and installation-specific conclusions cannot be drawn from the information provided.
Check Ratings Before Installation
People considering an Edge Pro unit can ask Clivet or an installer for the model-specific acoustic data, certification details and operating conditions behind published measurements. Installers can also explain how siting and the property’s surroundings may affect noise at nearby rooms and boundaries.
The source report does not announce another certification milestone or a timetable for additional test data. For now, the confirmed development is the award across the range; buyers should compare the relevant model’s documented noise and heating specifications with their property’s needs.
Key Questions
Which Clivet heat pumps received Quiet Mark certification?
The award covers Clivet’s Edge Pro air-source heat pump range, according to Cooling Post.
What does Quiet Mark certification indicate?
Quiet Mark is an independent programme associated with the UK’s Noise Abatement Society. The report says certification follows laboratory testing and assessment by its acoustic assessment and verification board.
How much quieter is the Edge Pro range?
Cooling Post reports sound levels up to 10 dB(A) lower than previous generations. The source does not provide absolute sound readings, model-by-model results or test conditions.
What capacities does the Edge Pro range offer?
The reported heating capacities run from 4.1 kW to 15.5 kW, while cooling capacities run from 4.5 kW to 15 kW. Models numbered 2.1 to 8.1 are reported to offer A+++ heating efficiency at 35°C and water temperatures up to 80°C.
Does certification guarantee low noise at every home?
No such guarantee is stated in the report. The award concerns an assessment of the product range; actual noise at a property may depend on the model, operating conditions, installation location and surroundings.
