AnswerAre heat pumps noisy?
No — a modern air-source heat pump runs at around 40–50 dB from a metre away, similar to a fridge or steady rainfall. Placement rules keep them quiet for you and neighbours.
In more detail
MCS installers follow noise limits for boundaries. Position and anti-vibration mounts keep noise low.
