Warmth pumps ‘too noisy’ for thousands and thousands of British properties, Authorities informed • Watts Up With That?
From NOT A LOT OF PEOPLE KNOW THAT

Heat pumps are too loud to be installed in millions of homes under the Government’s noise guidelines, ministers have been told.
The Government wants to install 600,000 heat pumps a year by 2028 to hit net zero targets, but a report by sound specialists warns uptake could be limited.
The study reveals that most heat pumps are too loud for many homes in built-up areas, such as terraced houses and flats, because they would break noise limits set for homeowners who want to install one without planning permission and with a government grant.
Local authorities are also braced for a rise in noise complaints as more of the green appliances are installed in urban areas, the report seen by The Telegraph reveals.
The findings, which were produced by a group of noise experts, have been sent to the Government to contribute to a review into heat pump noise being run by the Department for Energy Security and Net Zero (Desnz).
Air source heat pumps, which are positioned outside a home, can produce a low constant hum of between 40 and 60 decibels which is similar to the level of noise made by a fridge or dishwasher. They will typically run continuously throughout winter…..
In order to qualify for the government grant, heat pump installations must comply with regulations set out by the Microgeneration Certification Scheme (MCS) – including a minimum level of noise disturbance to neighbours. It means a heat pump must not generate a noise louder than 42 decibels within one metre of a neighbour’s door or window.
Yet the report, which was presented to the Institute of Acoustics at a conference, found that of the top heat pumps from the five main manufacturers, not one device would meet MCS standards on noise unless the unit was at least 4m away.
Peter Rogers, of Sustainable Acoustics, said all terraces, flats and tenement buildings – equivalent to 47pc of Britain’s housing stock – would struggle to install a heat pump under MCS guidelines. He also said some installations in semi-detached homes, which account for 31pc of homes in Britain, could breach guidelines.
To meet noise regulations and receive grant funding, some homeowners would have to build a sound barrier – potentially at a cost of up to £5,000 – said Jack Harvie-Clark, of Apex Acoustics. But even if sound-proofing was installed, it may not be enough to reduce the noise to an acceptable level.
Alternatively, they could opt for a costly split system, where part of the heat pump is built inside the house.
What’s the betting that the government won’t just relax the MCS standards?
