Do I Need a Permit to Install a Whole-House Natural Gas Generator? in Nederland
Whole-house standby generators connected to natural gas almost always require permits because the installation involves multiple regulated trades: a concrete pad, a dedicated natural gas line, a 200+ amp automatic transfer switch tied into the main electrical panel, and often outdoor noise and setback compliance. Unlike portable generators, permanent standby units are classified as fixed equipment and trigger electrical, plumbing/gas, and sometimes mechanical and zoning reviews.
Do you need a permit?
Usually yes
- Permitting authority
- Gemeente / Omgevingsloket + Netbeheerder
- Typical fee
- €300–€1 500
What triggers a permit
- Running a new dedicated natural gas supply line from the meter to the generator
- Installing an automatic transfer switch (ATS) that ties into the main electrical panel
- Pouring a concrete pad or installing a pre-engineered mounting base
- Placing the unit within zoning setback distances from property lines or structures
- Generator sound output exceeding local noise ordinance thresholds (typically 65–75 dB at the property line)
Country-specific detail
In the Netherlands, installing a noodstroomvoorziening (standby power system) connected to aardgas (natural gas) typically requires an omgevingsvergunning because the unit is a vast opgesteld toestel (permanently installed appliance) that affects the buitenzijde (exterior) and generates geluid (noise). The gasaansluiting (gas connection) must be approved by the netbeheerder (network operator — Liander, Stedin, or Enexis) and installed by a Gastec QA-certified installateur. The electrical installation — including the automatische omschakelaar (ATS) — must comply with NEN 1010 and be inspected by a Scope 10 gecertificeerde installateur. The Activiteitenbesluit (now part of Bal under Omgevingswet) sets geluidsnormen (noise limits) for installations — typically 45 dB(A) at the erfgrens (lot boundary) during evening hours. In woonwijken (residential areas), additional restrictions may apply via the bestemmingsplan. The unit must have a CE-markering and comply with the Gastoestelverordening.
