Electrical Panel Replacement Cost in 2026: Full Price Guide
Replacing an electrical panel costs $1,300 to $4,000 on average, with most homeowners paying around $2,500. A like-for-like swap of a 100-amp panel starts near $1,300, while upgrading to 200-amp service runs $1,800–$4,500, and a 400-amp panel can reach $6,000. Prices include the panel, breakers, labor, permit, and inspection.
How Much Does Panel Replacement Cost by Amperage?
| Panel Size | Installed Cost | Best For |
|---|---|---|
| 100-amp | $1,300 – $2,500 | Small homes, minimal electric appliances |
| 150-amp | $1,500 – $3,000 | Mid-size homes, moderate loads |
| 200-amp | $1,800 – $4,000 | Modern standard; EVs, heat pumps, additions |
| 400-amp | $2,500 – $6,000 | Large homes, workshops, multiple EVs |
Where these numbers come from: Labor pricing is anchored to the BLS median electrician wage of $34.37/hour (May 2025) with a standard 2.5–3.5× contractor overhead multiplier, plus 2026 panel/breaker material costs ($400–$1,200) and typical permit fees ($50–$500). A panel replacement is master-electrician work billed at the top of the rate scale — see electrician cost for how rates break down.
Panel Replacement vs. Service Upgrade — What’s the Difference?
These two terms get mixed up constantly, and the price difference is significant:
- Panel replacement (like-for-like): Swapping an old or failing panel for a new one at the same amperage. The utility service, meter, and wiring to the house stay the same. Cost: $1,300–$2,500.
- Service upgrade: Increasing the amperage coming into the house (typically 100→200 amp). This means a new panel plus new service entrance cable, a new meter base, utility coordination, and often grounding upgrades. Cost: $1,800–$4,500. See the full 200-amp service upgrade cost guide.
If you’re adding an EV charger, heat pump, or whole-house generator, get a load calculation first — you may need the upgrade, not just the swap.
What’s Included in the Price?
- The new panel and full set of breakers
- Labor (4–8 hours typical; one working day)
- Permit and municipal inspection ($50–$500)
- Utility disconnect and reconnect coordination
- Code-required updates (grounding/bonding, AFCI/GFCI breakers, surge protection in many jurisdictions)
Are Federal Pacific and Zinsco Panels Dangerous?
Yes — and this is the single most important reason homes get panels replaced regardless of age or capacity.
Federal Pacific Electric (FPE) Stab-Lok and Zinsco/Sylvania panels, installed in millions of U.S. homes from the 1950s–1980s, have a documented history of breakers that fail to trip under overload or short-circuit conditions. Independent testing conducted in connection with a U.S. Consumer Product Safety Commission (CPSC) investigation found FPE Stab-Lok breakers failed to trip at rates far exceeding industry standards. A breaker that doesn’t trip means a fault keeps pushing current through your wiring — which is how electrical fires start. The National Fire Protection Association (NFPA) attributes tens of thousands of U.S. home structure fires annually to electrical distribution equipment, and the Electrical Safety Foundation International (ESFI) lists outdated panels among the top residential electrical hazards.
If your panel says Federal Pacific, Stab-Lok, Zinsco, or Sylvania, most electricians and home inspectors recommend replacement — not repair. Many insurers now refuse or surcharge coverage on homes with these panels.
What Are the Signs You Need a New Panel?
- Frequently tripping breakers — or worse, breakers that never trip despite obvious overloads
- A fuse box instead of breakers, or an FPE/Zinsco brand panel
- Not enough capacity for an addition, EV charger, or generator
- Buzzing, crackling, warmth, or scorch marks at the panel — treat this as urgent and review what to do in an electrical emergency
- Flickering lights when large appliances start
- The panel is 25–40+ years old with original breakers

What Does the Permit and Inspection Process Look Like?
Panel replacement is permitted work everywhere in the U.S. Here’s the typical sequence:
- Electrician pulls the permit with your city or county ($50–$500, usually included in the quote).
- Utility coordination — power to the home is disconnected at the meter for the swap.
- The swap itself — 4–8 hours: old panel out, new panel mounted, every circuit re-landed on new breakers, grounding verified.
- Municipal inspection — an inspector verifies the work meets the National Electrical Code before final sign-off.
- Utility reconnect — same day in most cases.
If a contractor offers to skip the permit to save money, walk away. Unpermitted panel work can void your homeowner’s insurance, kill a future home sale, and leave code violations hidden behind a dead front. Always verify the contractor’s license before signing.
Why Is Panel Replacement Never a DIY Job?
Unlike almost every other home project, the line side of your panel — the service lugs feeding it — remains energized even when the main breaker is off. The only way to fully de-energize it is a utility disconnect at the meter. ESFI consistently identifies panel and service work as the highest-risk category of residential electrical work; contact with energized service conductors at 240V can be fatal. Between the electrocution risk, the code complexity, and the insurance/permit requirements, this is master-electrician territory — period.
What Affects the Cost?
- Amperage — higher capacity means a bigger panel, heavier wire, and more expensive breakers
- Replacement vs. service upgrade (see above — the upgrade adds $500–$1,500+)
- Panel location — relocating a panel or working in a tight crawl space adds hours
- Code upgrades required by the inspector (AFCI/GFCI breakers add $40–$80 each)
- Permit fees in your area
- Local labor rates — see electrician cost for city variation
How Can You Save?
- Get 3 quotes — panel pricing varies more than almost any other electrical job
- Bundle the panel with an EV charger install or other planned circuits in one permit
- Check utility and electrification rebates — many utilities subsidize service upgrades, and federal programs listed at ENERGY STAR’s tax credit hub can apply when the upgrade enables qualifying electrification projects
- Vet candidates with these questions to ask an electrician
Frequently Asked Questions
How much does it cost to replace an electrical panel? $1,300–$4,000 on average. A like-for-like 100-amp swap starts near $1,300; a 200-amp panel typically runs $1,800–$4,000 installed; 400-amp panels reach $6,000.
How long does a panel replacement take? Usually 4–8 hours (one day), including the utility disconnect/reconnect. The municipal inspection may happen the same day or within a few days.
Do I need to upgrade to 200 amps? If you’re adding an EV charger, heat pump, large appliances, or an addition, often yes. A load calculation gives the definitive answer — see 200-amp service upgrade cost.
Are Federal Pacific and Zinsco panels really dangerous? Yes. Testing tied to a CPSC investigation found FPE Stab-Lok breakers fail to trip at abnormally high rates, and Zinsco panels have similar documented failure modes. Most electricians, inspectors, and insurers treat them as replace-on-sight items.
Can I replace an electrical panel myself? No. The service lugs stay energized at 240V even with the main breaker off, the work requires a permit and inspection, and DIY panel work can void insurance. Hire a licensed master electrician and verify the license.
