Full system rewiring ranges €1,500–€4,000. Panel upgrades and compliance work costs €800–€2,500. Custom projects are quoted after site assessment.--- **Q: How long does a complete electrical installation take?** A: Basic installations take 2–3 days. Full system rewiring in a standard home takes 5–7 days. Complex projects may extend to 2–3 weeks depending on size and scope.--- **Q: Is my electrical system up to Belgian standards?** A: We provide a complete assessment during the initial visit. Most homes built in the last 20 years comply. Older systems often need updates for safety and capacity reasons.--- **Q: What is RGIE compliance?** A: RGIE is the Belgian electrical safety standard. All our work complies fully with RGIE requirements for installation methods, circuit protection, and grounding.--- **Q: Do I need an electrical certificate?** A: Yes, for new installations and major upgrades, a Conformité Certificate is required. We handle the certification process and testing.--- **Q: Can you upgrade my electrical panel?** A: Yes, we specialize in panel upgrades to increase capacity, add circuits, and improve safety. This is often necessary for EV charging or smart home systems.--- **Q: What about adding circuits for new appliances?** A: We can safely add new circuits for kitchens, bathrooms, EV chargers, and other equipment. We assess load capacity to ensure safe installation.--- **Q: Do you handle grounding and earthing?** A: Yes, proper grounding is critical for safety. We install and verify grounding systems according to Belgian standards.--- **Q: What's a differential circuit breaker?** A: It's a safety device that cuts power if leakage current is detected, protecting against electric shock.
