Electrical Costs by Item

When Is Rewiring Necessary?
| Warning sign | Risk | |---|---| | Old aluminium wiring (pre-1980) | Fire risk due to resistance increase | | No RCD (residual current device) | Electrocution risk on earth faults | | Consumer unit older than 30 years | Breakers may no longer trip reliably | | Fuse wire still present | Does not comply with NEN 1010-2023 | | Breakers tripping repeatedly | Overloaded circuits | | KEMA inspection date older than 25 years | Liability risk if fire or damage occurs |
Do You Need a Permit?
Almost never for routine electrical work:
- Replacing wiring within existing structures: permit-free
- New wall penetrations: only notifiable if structural
- EV charger >11 kW, large PV system or heavy connection: notify grid operator (netbeheerder)
Do You Need an Architect?
- Standalone electrical renovation: no architect needed; use a certified electrician (NEN 1010)
- Part of a renovation or extension: architect includes electrical plan in building specifications
- Energy performance upgrade project: architect or building physics advisor coordinates electrical installations with heat pump and ventilation
Certification and Inspection
- NEN 1010: Dutch installation standard — electrician must install to this standard
- KEMA/SCIOS inspection: recommended after completion; often required by insurers for rental properties
- Certified contractors: look for UNETO-VNI or Techniek Nederland members
Tips to Save Costs
- Combine electrical renovation with bathroom or kitchen renovation — walls are already open
- Collect 3 quotes — rates vary considerably (€ 45–€ 85/hour)
- Ask the electrician to include EV charger prep and solar inverter connection in the quote
- Draw up a preliminary electrical plan to avoid expensive call-backs
Conclusion
Electrical rewiring in the Netherlands in 2026 costs € 3,000–€ 12,000 for a terraced house. No permit required. Combine with other renovations to maximise value.
