⚡ Electrical Panel Upgrade Cost: 100A to 200A, What's Fair in 2026

Electrical panel upgrades are one of the most common major home improvement projects, and one of the most widely misunderstood when it comes to pricing. The range of quotes for the same job can be enormous, anywhere from $1,800 to over $6,000. Here is what drives that range and what fair pricing actually looks like.

What Is an Electrical Panel Upgrade?

Most homes built before 1990 have 100-amp service panels. Modern homes, especially those adding EVs, hot tubs, home offices, or significant HVAC upgrades, often need 200-amp service. A panel upgrade replaces the main electrical service entrance, the panel box itself, and the circuit breakers.

Some older homes still have 60-amp service (most built before the 1960s) or Federal Pacific/Zinsco panels, which are considered safety hazards and should absolutely be replaced regardless of capacity.

What a Panel Upgrade Involves

A standard 100A to 200A upgrade includes: pulling a permit with your local municipality, coordinating with the utility company to disconnect and reconnect service, installing a new 200A panel box, installing new circuit breakers for all existing circuits, upgrading the grounding system if needed, and any necessary work at the meter socket. The utility company typically handles their portion for free; you pay for everything from the meter in.

What Does It Cost in 2026?

Here are realistic installed prices for a panel upgrade, all-in with permit:

100A to 200A upgrade (straightforward, no additional circuits, no panel relocation): $1,800 to $3,200 in most markets. Simpler jobs in lower-cost markets can come in at $1,500. Complex jobs in high-cost markets (California, New York, New England) can run $3,500 to $4,500.

100A to 200A upgrade with panel relocation: Add $500 to $1,500 for moving the panel to a new location, which requires new conduit runs.

Upgrading from a Federal Pacific or Zinsco panel to 200A: $2,200 to $4,000. Similar to above but may include additional circuit testing and rewiring.

200A to 400A upgrade (for large homes or EV charging at scale): $3,500 to $7,000+. This involves utility coordination for a larger service drop and is more complex.

Just replacing a failed panel (same amperage, same location): $1,200 to $2,500.

What Drives the Price Up Legitimately

Permit fees: $150 to $600 depending on municipality. This is non-negotiable. An electrician who offers to skip the permit is offering to save you $200 while creating massive liability for you and potential issues with homeowner's insurance.

Utility company coordination: Some utilities charge fees ($100-400) for their portion of the service upgrade. This should show up as a pass-through in your quote.

Panel location: Panels in finished spaces, tight closets, or locations that require significant drywall work cost more to upgrade.

Old wiring: If your home has aluminum wiring or knob-and-tube wiring, the electrician may identify additional work needed for safety and code compliance. This is legitimate, though always worth a second opinion.

Adding circuits during the upgrade: If you are simultaneously adding circuits for an EV charger ($300-600), hot tub ($400-800), or home office ($200-400), that work can be bundled for efficiency but adds to the total.

Red Flags in Panel Upgrade Quotes

Watch for quotes that do not include the permit explicitly. A quote that says "panel upgrade, $2,100" with no mention of permit is either including it without stating it (ask) or planning to skip it (run). Watch for quotes that do not mention utility coordination. This is a required step and skipping it means the job cannot be done correctly. Watch for vague equipment specs. The quote should name the specific panel brand and amperage, such as "Square D Homeline 200A 40-space main breaker panel." Eaton, Square D, Leviton, and Siemens are all reputable brands. Avoid cheap imported knockoffs.

Getting the Best Price

Get three quotes minimum. Panel upgrades are not emergency work in most cases, so you have time to compare. Ask each electrician: Do you pull the permit, and what does it cost? What panel brand are you installing? How do you coordinate with the utility, and is there a fee? What is the timeline from booking to completed inspection?

The best electricians will answer all of these without hesitation. The ones who are vague about permit work or utility coordination are not the ones you want doing this job.
