Electrical wiring costs depend heavily on the scope of work — running a single new circuit costs $200–$500, while fully rewiring a 2,000 sq ft house runs $8,000–$20,000+ in the US. In Poland, full rewiring costs PLN 15,000–40,000, and in the Netherlands €6,000–€18,000. Licensed electricians charge $50–$130/hour in the US, and wiring work almost always requires permits and inspections.

What affects the cost?
- House age and existing wiring — older homes with knob-and-tube or aluminum wiring cost more to rewire due to removal and code compliance
- Accessibility — open walls during a renovation are far cheaper to wire than fishing cables through finished walls and ceilings
- Number of circuits and outlets — modern code requires more circuits than older homes had (dedicated circuits for kitchens, bathrooms, laundry)
- Wire type — copper Romex (NM-B) is standard; conduit wiring or aluminum requires different labor and materials
- Permits and inspections — most jurisdictions require electrical permits ($50–$500) with rough-in and final inspections
- Panel capacity — if your panel can't support new circuits, a panel upgrade adds $1,500–$4,000
Costs by country
Wiring costs in the United States
US electricians charge $50–$130 per hour for wiring work, with most residential wiring projects quoted as flat-rate jobs. Running a new circuit from the panel to a room costs $200–$500, including wire, breaker, and labor. Full house rewiring typically costs $4–$8 per square foot — a 2,000 sq ft home runs $8,000–$16,000. Homes with lathe-and-plaster walls or limited attic access cost 20–40% more due to the difficulty of pulling wire.
All wiring work requires a licensed electrician in every US state. Get 2–3 detailed quotes that specify wire gauge, circuit count, and whether drywall repair is included. Verify the electrician pulls permits — unpermitted work can void your homeowner's insurance and create problems at resale.
How to save on wiring costs
- Combine with renovations — rewiring during a kitchen or bathroom remodel (with walls open) cuts costs 30–50%
- Get multiple quotes — pricing varies 30–40% between electricians for the same scope
- Plan circuits carefully — consolidating runs reduces labor time
- Do cosmetic work yourself — patch drywall and paint after the electrician finishes to save on labor
- Ask about phased work — rewire the most critical areas first if budget is tight

Wiring costs in Spain
Spanish electricians charge roughly €25–€45 per hour, with most domestic work quoted as a flat-rate job rather than hourly. Adding a single outlet or switch runs €70–€200, a new circuit €150–€400, and a dedicated 240V circuit for an EV charger or dryer €300–€900. Rewiring an 80 m² piso costs €3,500–€7,500; a 140 m² house €6,000–€12,000; a full rewire of a 200 m²+ vivienda €9,000–€15,000. Rates on the Costa del Sol and in central Madrid/Barcelona trend 20–30% above the national average.
Electrical work must comply with the Reglamento Electrotécnico de Baja Tensión (REBT) and any new or substantially modified installation requires a Boletín Eléctrico (CIE) signed off by an authorised installer (instalador autorizado) before the utility will connect the meter. Most domestic electricians operate as autónomos: invoices include 21% IVA, and an unregistered cash job will not produce the boletín you need at sale or rental. Always ask for the installer's número de autorización in the comunidad autónoma before signing the budget.
Frequently asked questions
How much does it cost to wire a house?
Wiring a new 2,000 sq ft house costs $4,000–$10,000 in the US ($2–$5 per square foot). Rewiring an existing home runs $8,000–$15,000+ because walls must be opened and closed. Adding a single circuit costs $200–$500. Whole-house rewires include new outlets, switches, panel work, and inspections.
Do I need to rewire an old house?
Yes if you have: knob-and-tube wiring (homes pre-1950), aluminum wiring (1965–1973), cloth-insulated wiring, or frequent breaker trips. These are fire hazards and many insurers will refuse coverage. Modern copper romex wiring is safe for 60+ years if not damaged. Have an electrician inspect any home over 40 years old.
How long does electrical wiring take?
New construction wiring (rough-in): 3–5 days for a 2,000 sq ft home. Final trim (outlets, switches, fixtures): 2–3 days. Whole-house rewire of an existing home: 2–6 weeks because walls must be opened, wiring run, walls patched, then painted. Per-room rewires take 1–2 days each.
Can I wire my own house?
Most jurisdictions allow homeowners to wire their own primary residence with a permit and inspection. However, mistakes are dangerous (fire, electrocution) and can void homeowner's insurance. DIY wiring rarely passes inspection on the first try. Most homeowners save $0 net once errors and inspection issues are accounted for.
