Do You Need a Permit for Whole-House Repiping? in Nederland
Whole-house repiping — replacing all supply lines — typically requires a plumbing permit because it modifies the water distribution system. Inspections verify correct pipe sizing, proper material transitions, and code-compliant connections. Skipping the permit risks failed resale inspections and insurance claim denials for water damage.

Country-specific detail
In the Netherlands, like-for-like replacement of internal water pipes (waterleiding vervangen) in an existing dwelling is generally vergunningvrij (permit-free). However, major plumbing modifications that change the building's structure — such as cutting through load-bearing walls or floors to reroute piping — may require a melding or vergunning via Omgevingsloket. Work must comply with NEN 1006 (Waterkwaliteit in gebouwen) and Waterleidingbesluit standards. If the work involves the watermeter or the connection to the municipal supply (drinkwateraansluiting), coordination with the drinking water company (Vitens, Evides, PWN, etc.) is required.
