Permits and noise protection in the Canton of Aargau
Since 1 April 2025, air/water heat pumps in the Canton of Aargau can be realised within building zones under the notification procedure – provided a noise protection certificate is available, another location would bring only insignificant advantages in terms of noise law and no exemption permit for distances is required. Exceptions are zones with increased requirements for the townscape and landscape as well as buildings under heritage protection (Canton of Aargau).
The notification is made via the cantonal platform for energy enforcement; if the municipality raises no objections within 30 days, construction can begin. The noise assessment is based on the Cercle Bruit enforcement guidelines (Heat pump leaflet, Canton of Aargau).
Official information without guarantee – the requirements of the canton and municipality are decisive.
