Panel upgrades catch most homeowners off guard on cost, and the quotes that come back can vary by thousands of dollars for what sounds like the same job. That gap is almost always explainable — labor markets, panel location, service entrance condition, and permit fees all move independently. This guide breaks each one down so you can read a quote and know what's in it. If you already know your upgrade type and just want a regional number, jump to the regional labor index or use the cost estimator below it.

The Verdict
Typical range: $1,500–$4,000 for most homes upgrading to 200A service.

A straight panel swap at the same amperage runs $1,200–$2,500. A 200A→400A upgrade — needed for large homes with solar, battery storage, and multiple EVs — starts around $3,000 and can reach $8,000+ when service entrance and utility work are involved.

Cost by Upgrade Type

Upgrade Type Typical Cost Range What's Included
100A → 200A upgrade $1,500–$3,500 New panel, service entrance work, permit, utility coordination
200A panel swap (same amperage) $1,200–$2,500 New panel, permit — no service entrance change required
200A → 400A upgrade $3,000–$8,000+ New panel, new service entrance, utility work, permit
Fuse box → breaker panel conversion $1,500–$4,000 New panel, service entrance likely replaced, permit
Add sub-panel only $500–$1,800 Sub-panel + feeder circuit — no main service change
Replace single circuit breaker $150–$300 Labor + breaker — only if the panel itself is sound

All ranges above assume licensed, permit-pulled work. DIY electrical panel work is illegal in most jurisdictions and will void homeowner's insurance. A permit is always required — see the FAQ below for what that process looks like.

What the Labor Breakdown Looks Like

The cost table above shows the total. Here's what's inside a typical 100A→200A upgrade invoice:

Line Item Typical Cost Notes
Electrician labor (8–12 hrs) $800–$1,800 Master electrician rate + helper; varies by region
New 200A panel (materials) $200–$600 Square D, Leviton, Eaton — brand matters less than installation quality
Permit fee $75–$500 Set by municipality — always required, cannot be skipped
Utility coordination / reconnection $0–$500 Utility-handled at no charge in most areas; some charge a reconnection fee
Meter base / service entrance work $200–$800 Required when upgrading amperage; usually not needed for a straight swap

What Drives Costs Above the Typical Range

  • Panel in a hard-to-access location. Inside a finished wall, in a tight mechanical room, or mounted unusually high — each adds labor time.
  • Service entrance needs replacement. Older homes often have undersized conduit or aluminum wiring at the service entrance that must be upgraded when the panel changes. This is the single most common reason a quote comes in high.
  • Meter relocation. If the meter needs to move for an addition, detached garage, or utility requirement, that adds $500–$2,000 to the job.
  • Panel relocation. If a remodel forces the panel itself to move to a new location — not just a swap in place — that's a separate cost layer. See what panel relocation costs for the full breakdown.
  • Recalled panel brand (Federal Pacific, Zinsco). These require additional safety protocols, and some contractors charge a modest premium. More importantly, many insurers won't renew coverage until they're replaced — so the cost of not replacing them is real.
  • Coastal or high-wage markets. Labor rates in LA, NYC, Miami, and Seattle run 20–40% above the national average. If you're in one of these markets, add that multiplier to any national estimate you find online.
Scope clarity: If a quote includes a whole-house rewire alongside the panel upgrade, ask the electrician to explain what they found that makes it necessary. The panel job and any rewiring are separate scopes — understanding both helps you evaluate the recommendation.
Have a fuse box? Converting to a modern breaker panel runs at the top of the cost range ($1,500–$4,000) because the service entrance wiring usually needs replacing at the same time. Most insurers now require a breaker panel for coverage — some won't write a new policy on a fuse-box home. If you're already doing the work, the incremental cost of converting is small. For the full picture on what older homes involve — wiring types, recalled brands, and the rewiring question — see the old house electrical upgrade guide.

Sub-Panel vs. Full Upgrade: The Cheaper Fork

If the trigger is one specific area of the house — a detached garage, a home addition, or an EV charger on the far side of the property — adding a sub-panel is worth pricing before committing to a full service upgrade. A sub-panel runs $500–$1,800 and doesn't require utility coordination or service entrance work. The trade-off: it doesn't add capacity to your main service, so if the main panel is already maxed out, a sub-panel won't help.

Upgrade vs. Replace: When Replacement Is Actually Cheaper

If your panel is 25+ years old, a full replacement often makes more financial sense than repairing or partially upgrading it. (Not sure what era your panel is from or what service standard it was built to? See our 200-amp history guide.) A new panel comes with a 10-year warranty and a fresh inspection, and once labor is already involved, the difference in materials cost between a repair and a full swap is often small. A straight 200A-for-200A replacement typically costs $1,200–$2,500 — and eliminates the question of whether the existing unit will pass inspection.

Not sure whether your situation calls for repair or full replacement? See our guide: Electrical Panel Repair vs. Replacement. If replacement is confirmed, our electrical panel replacement guide covers the full process, recalled brands, and what the permit and inspection involve.

How to Get Accurate Quotes

The 3-bid approach is standard advice, but knowing what to compare matters more than the number of bids. Ask each electrician to itemize: labor hours, materials with brand, permit fee, and whether utility coordination is included. A low bid that excludes the permit is not actually cheaper — permits are legally required and the cost is real.

In most states, only licensed master electricians can pull electrical permits for panel work — any contractor doing this work will have the relevant credential and can give you their license number. For a full list of what to ask and red flags to watch for, see: How to Hire an Electrician for a Panel Upgrade.

Financing and Rebate Options

If upfront cost is a barrier, three options are worth investigating:

  • IRA Section 25C tax credit — expired December 31, 2025. See our tax credit guide for current status and what may have changed.
  • State and utility rebates — several states and utilities offer separate rebates for panel upgrades tied to electrification. These layer on top of the federal credit in some cases. Check your state's program status through DSIRE.
  • Contractor financing and loan options — many electricians offer financing through GreenSky, Mosaic, or similar programs. For a full comparison of personal loans, HELOCs, home equity loans, and government-backed options, see the panel upgrade financing guide.

Frequently Asked Questions

How much does it cost to upgrade an electrical panel to 200 amps?
A 100A→200A upgrade typically costs $1,500–$3,500 for most homes. The range exists because panel location, service entrance condition, and permit fees all vary. If the utility needs to move your meter, add another $500–$2,000. See the cost table above for a full breakdown by upgrade type.
What's the difference between upgrading and replacing an electrical panel?
"Upgrade" means increasing the amperage capacity — for example, going from 100A to 200A service. "Replacement" means swapping the panel unit itself at the same amperage, usually because the existing panel is aged, recalled, or damaged. A straight 200A-for-200A replacement costs less ($1,200–$2,500) because it doesn't require service entrance work.
Does replacing a fuse box cost more than replacing a breaker panel?
Usually yes. Converting an old fuse box to a modern breaker panel typically costs $1,500–$4,000 — at the higher end of the range — because the work often involves replacing the service entrance wiring as well. Fuse boxes are typically found in homes built before 1960, and most inspectors and insurers require modern breaker panels for updated coverage.
How much does it cost to replace a Federal Pacific or Zinsco panel?
Federal Pacific (Stab-Lok) and Zinsco panels are widely flagged by inspectors as fire hazards. Replacement costs are the same as a standard panel swap — $1,200–$2,500 for the unit swap itself — but contractors may charge a small premium for dealing with these panels due to the additional safety protocols involved. Many insurers will not write or renew policies until these are replaced.
Is a permit required for an electrical panel upgrade?
Yes, in virtually every US jurisdiction. Only a licensed electrician can legally pull an electrical permit for panel work in most states. The permit fee itself ranges from $75–$500 depending on municipality. DIY panel work is illegal in most areas and will void your homeowner's insurance — this is one job where the permit isn't optional.
