Electrical Panel Upgrade Cost: 100A to 200A (2026 Pricing)

Most homes built before 1990 have 100-amp electrical panels. That was enough when the biggest draw was a central AC unit and a dryer. Today, with home offices, EV chargers, heat pumps, and modern kitchens, 100 amps is often not enough. Upgrading to a 200-amp panel gives your home the capacity to handle current and future electrical loads safely.

How Much Does a Panel Upgrade Cost?

National average: $1,800-$4,500 for a full 100A to 200A upgrade.

Here is a more detailed breakdown:

If your utility requires a new meter base or service entrance cable, expect to land on the higher end. Homes that need the service entrance rerouted from overhead to underground can add $2,000-$5,000 to the total.

What Is Included in the Upgrade?

A standard panel upgrade includes removing the old panel, installing a new 200-amp panel with circuit breakers, connecting all existing circuits, upgrading the service entrance cable, coordinating the utility disconnect and reconnect, and pulling the required permit. The electrician should also label every circuit in the new panel.

Some electricians include the meter base replacement in their quote. Others list it separately. Always confirm what is and is not included before signing.

When Do You Need a Panel Upgrade?

Your breakers trip frequently. If you are resetting breakers more than occasionally, your panel may be at capacity.

You are adding a major appliance. An EV charger (40-60A), heat pump (30-60A), or hot tub (40-50A) can push a 100A panel past its limit.

Your panel uses fuses or is a known hazard brand. Federal Pacific, Zinsco, and some Pushmatic panels have documented safety issues. Insurance companies may require replacement.

You are renovating or adding square footage. Building departments typically require a 200A panel for major renovations. Your electrician will confirm what local code requires.

Your home still has 60-amp service. This is common in homes built before 1960. A jump from 60A to 200A costs $2,500-$5,500 because it usually requires a full service entrance replacement.

The Permit Process

Panel upgrades require a permit in virtually every jurisdiction. Your electrician pulls the permit, does the work, and the local inspector signs off. The utility company is involved because they need to disconnect and reconnect power at the meter.

Typical timeline: 1-2 weeks from permit application to completed inspection, though this varies by municipality. The actual installation takes one day in most cases.

200A vs 400A: Do You Need More?

For most single-family homes, 200 amps is sufficient even with an EV charger and modern appliances. You might need 400A service if you have a very large home (over 4,000 sq ft) with multiple HVAC systems, a pool, a workshop, and an EV charger. A 400A upgrade runs $4,000-$8,000.

How to Save on the Upgrade

Bundle with other electrical work. If you need outlets added, a sub-panel in the garage, or wiring for an EV charger, doing it all at once saves on labor.

Get three quotes. Panel upgrade pricing varies significantly between electricians. Make sure all quotes include the permit, meter base (if needed), and inspection.

Check utility rebates. Some utilities offer incentives for panel upgrades tied to electrification projects like heat pumps or EV chargers. Ask your utility or check the Database of State Incentives for Renewables and Efficiency (DSIRE).

FAQ

How long does a panel upgrade take?

Most panel upgrades are completed in one day, typically 4-8 hours of on-site work. Your power will be off for several hours during the swap. The permit and inspection process adds a few days to a couple of weeks depending on your local building department.

Will I lose power during the upgrade?

Yes. The utility disconnects power at the meter while the electrician swaps the panel. Expect 4-8 hours without electricity. Plan accordingly for refrigerated food and any medical equipment that requires power.

Can I upgrade my panel myself?

No. Electrical panel work requires a licensed electrician in every state. It involves working with the utility service entrance, which carries lethal current even when your main breaker is off. This is not a DIY project.

Does a panel upgrade increase home value?

A 200A panel is expected in modern homes. It removes a barrier for buyers who want to add EV chargers or major appliances. It will not dramatically increase your sale price, but it prevents your home from being flagged during inspection and can make insurance easier to obtain.

How do I know if my panel needs upgrading?

Check the main breaker rating printed on the breaker handle. If it says 100 (or 60), you have a 100A (or 60A) panel. If your electrician confirms the panel is at or near capacity, or if you are planning to add large loads, an upgrade is the right move.
