Clivet says its Edge Pro air-source heat pump range has received Quiet Mark certification following laboratory testing and assessment. The range’s noise-control design includes a compressor enclosure, larger slower-turning fans and vibration damping; the certification does not, in the supplied report, specify a single noise level for every model.
Clivet’s Edge Pro air-source heat pump range has received Quiet Mark certification after laboratory testing and assessment, according to UK trade publication Cooling Post. The award covers the range and recognizes its acoustic performance under Quiet Mark’s assessment process, giving prospective buyers an independent certification to consider alongside heating capacity and efficiency.
Quiet Mark is an independent certification programme associated with the UK’s Noise Abatement Society. It assesses products and building materials for acoustic performance, and the Edge Pro award followed laboratory testing and review by Quiet Mark’s acoustic assessment and verification board. The report says certification applies across the Edge Pro range, rather than identifying only a particular model.
Clivet’s design incorporates a sound-insulating enclosure around the compressor, larger fans intended to operate at lower rotational speeds, and a structure designed to damp vibration. These features, the report says, have helped the Edge Pro achieve sound levels up to 10 dB(A) lower than previous generations. “Up to” describes the maximum reported reduction; the source does not provide model-by-model readings or the test conditions behind that comparison.
The range’s published specifications include heating capacities from 4.1 kW to 15.5 kW and cooling capacities from 4.5 kW to 15 kW. Models numbered 2.1 to 8.1 are listed as offering A+++ heating efficiency at a 35°C operating condition and the ability to produce water at temperatures up to 80°C. These figures describe product specifications, not measured performance in every home or installation.
Noise Certification for Home Heating
Heat pumps operate near homes and can be heard by residents and neighbours, particularly when equipment is installed close to living areas or property boundaries. A third-party acoustic certification can give buyers and installers another point of reference when comparing systems, alongside efficiency, capacity, cost and installation requirements. It may also be relevant where local planning rules or site conditions make noise a consideration.
The award does not, by itself, establish that every Edge Pro installation will be inaudible or suitable for every location. Actual sound levels can depend on the unit model, operating conditions, placement and surrounding environment. Quiet Mark’s like-for-like method is relevant here: the source says it compares heat pumps of comparable sizes rather than ranking units of different sizes as if they were directly equivalent.

How Quiet Mark Assesses Heat Pumps
Quiet Mark is described by Cooling Post as a programme associated with the Noise Abatement Society. Its process for this award involved laboratory testing and review by an acoustic assessment and verification board. The source says assessments compare heat pumps on a like-for-like basis, grouping units of comparable sizes rather than treating the whole market as one category.
The Edge Pro’s reported noise-reduction measures are part of its product design: a compressor sound enclosure, larger fans running at lower rotational speeds, and vibration damping. The report compares its sound levels with those of previous generations, but does not identify the specific predecessor models or provide the baseline readings. The certification is therefore a new recognition of the range’s acoustic assessment, while the numerical comparison remains limited by the detail published in the report.
“The certification follows laboratory testing and assessment by the Quiet Mark acoustic assessment and verification board.”

Published Acoustic Data Limits
The source report does not give individual sound-pressure or sound-power readings for Edge Pro models, the measurement distance, operating mode or laboratory conditions. It also does not identify which previous-generation models form the comparison behind the reported reduction of up to 10 dB(A). The certification indicates that the range passed Quiet Mark’s assessment, but the supplied information is not enough to independently compare exact noise levels across specific models.
Further details such as certification documentation, the assessment date and the precise models included are not provided. Nor does the report describe how sound levels may vary in real-world installations. Those details remain relevant to buyers and installers evaluating a particular site.
Details Buyers Can Check
Prospective buyers can compare the relevant Edge Pro model’s technical data and ask Clivet or an installer for its acoustic figures and the Quiet Mark assessment details. Installers will still need to select equipment for the property, position it appropriately and account for local requirements; a range-wide certification does not replace site-specific assessment.
The source report does not announce a further testing milestone or a planned expansion of the certification. The next useful information would be model-level acoustic data and the test conditions behind the reported comparison with previous generations. Until those are available, the confirmed development is the certification itself and the stated design features supporting it.
Key Questions
Which Clivet heat pumps received Quiet Mark certification?
The certification covers Clivet’s Edge Pro air-source heat pump range, according to Cooling Post. The report does not list individual certified model numbers separately.
What does Quiet Mark certification mean in this report?
Quiet Mark is an independent certification programme associated with the UK’s Noise Abatement Society. The Edge Pro range received certification after laboratory testing and assessment by the programme’s acoustic assessment and verification board.
How much quieter is the Edge Pro range?
The source reports sound levels up to 10 dB(A) lower than previous generations. It does not provide exact readings for each model, test conditions or the specific predecessor models used for comparison.
What are the Edge Pro range’s stated capacities?
The report lists heating capacities of 4.1 kW to 15.5 kW and cooling capacities of 4.5 kW to 15 kW. Models 2.1 to 8.1 are stated to offer A+++ heating efficiency at 35°C and water temperatures up to 80°C.
