Can I install a heat pump in Switzerland?
Yes — often via the simplified notification procedure, with noise control. Many heat pumps go via the notification procedure in the cantons rather than a full building permit (e.g. air-water pumps with an outdoor unit up to 2 m³, ground-source, district-heating connections). A 30-day rule applies: if nothing is ordered against it, you may build. In core zones and protection perimeters a permit is still needed. Every air-water pump needs a noise certificate (federal Noise Abatement Ordinance): in residential zones usually 50 dB(A) day / 40 dB(A) night at the neighbour's window, with the night value binding. There's no fixed metre distance; the calculated dB value decides. Subsidies come via the Buildings Programme — apply before building. In short: yes, usually with notification and a noise certificate.
📋 The rules
- Often notification rather than a building permit
- 30-day rule: without objection you may build
- Air-water: noise certificate required
- Residential usually 50 dB day / 40 dB night (night binds)
- Buildings Programme subsidy: apply before building
🔓 Exceptions
- Core zones/protection perimeters: ordinary building permit needed
- No statutory metre distance; the dB value is decisive
- Night quiet-mode 19:00–07:00 often expected
⚠️ Penalties & fines
Installing a notifiable or permit-requiring heat pump without notification/permit or breaching the noise limits risks retroactive conditions, removal or soundproofing measures, and neighbour claims. Beware a myth: "I can install a heat pump with no formalities" is not quite right — usually a notification is needed and always a noise certificate, and in protection zones a permit. Tip: file the notification with the noise certificate, submit the subsidy application before installation, and plan a quiet night mode to avoid conflicts with neighbours.

❓ Frequently asked
Do I need a permit for a heat pump?
Often not. Many heat pumps go via the simplified notification procedure rather than a full building permit, such as air-water pumps with a small outdoor unit, ground-source systems and district-heating connections. In core zones and protection perimeters an ordinary permit is still needed. Check the procedure with your commune.
What do I need to consider about noise?
Every air-water heat pump needs a noise certificate under the federal Noise Abatement Ordinance. In residential zones, usually 50 decibels by day and 40 by night apply, measured at the neighbour's window. The night value is generally binding, which is why a quiet night operation is important.
How does the notification procedure work?
In the notification procedure you submit the planned heat pump to the authority. If nothing is ordered against it within thirty days, you may start installation. For air-water pumps the noise certificate is part of it. In protection zones, a building permit is required instead of the notification.
Is there a minimum distance to the neighbour?
There's no statutory metre distance. What matters is whether the calculated noise limits are met at the neighbour's window. As a rule of thumb a few metres is often cited, but the dB value is decisive, not a fixed distance. So plan the siting with a noise calculation.
Do I get a subsidy?
Yes, the Buildings Programme co-funds replacing a fossil or electric heating system with a heat pump. It's important to submit the subsidy application before installation, otherwise the entitlement is lost. You'll find the exact contributions on your cantonal funding portal.
