Fuse box replacement costs by scenario
1. Price per situation
| Situation | Cost including labour | |---|---| | Replace consumer unit (single-phase, 1–6 circuits) | € 400–€ 800 | | Replace consumer unit (single-phase, 8–12 circuits) | € 700–€ 1,500 | | Add extra circuits to existing unit | € 200–€ 600 | | New three-phase connection | € 2,500–€ 5,000 | | Earth electrode installation | € 300–€ 600 | | Surge protection addition | € 150–€ 350 |

When is fuse box replacement required?
- No RCDs (residual current devices) — legally required under NEN 1010 during major renovation
- Consumer unit older than 30–40 years — inspection recommended; insurer may reject fire claims
- Installing solar panels or EV charger — grid operator may require an upgrade
- Three-phase connection desired — when heat pump + induction hob + EV charger run simultaneously
Tips for fuse box replacement
- Always use a certified electrician — only UNETO-VNI certified installers can install and certify
- Combine with other electrical work — adding sockets or lighting simultaneously saves cost
- Check whether three-phase is worthwhile — a single heat pump works fine on single-phase; three-phase pays off with multiple large loads
- Engage your grid operator early — capacity changes can take 6–12 weeks waiting time
- Request the NEN 1010 certificate — required after completion, and needed for building permits and property sale
Permit for fuse box replacement
Fuse box replacement: no permit required.
Exception: a new three-phase main connection requires an application to your grid operator (Liander / Stedin / Enexis) — free but subject to lead times.
