How Much Does an Electrical Panel Upgrade Cost?

Service entrance replacement. If only the panel box needs replacing and the service entrance cable (the thick cable from the utility meter to the panel) is in good condition and rated for 200A, the job is simpler and cheaper. But many 100A-to-200A upgrades require a new, heavier service entrance cable, which adds $500 to $2,000 depending on the run length and whether it's underground or overhead.

Panel location. If the panel is in an accessible location (garage wall, basement wall), the work is straightforward. Panels in tight closets, behind finished walls, or in locations that don't meet current code clearance requirements (36" clear in front, 30" wide) may need to be relocated, adding $500 to $1,500 in labor and materials.

Code updates. When you upgrade a panel, the electrician must bring the panel area up to current code. This often means adding AFCI breakers for bedrooms and living areas ($30 to $50 each vs. $5 to $10 for standard breakers), adding a whole-house surge protector ($100 to $300), and ensuring proper grounding. These code requirements vary by jurisdiction.

Utility coordination. The utility company must disconnect power before the panel swap and reconnect afterward. Some utilities do this for free; others charge $100 to $200. In some areas, the utility requires their own inspection before reconnection, which can add a day to the timeline.

Number of circuits. If you're adding circuits (for an EV charger, hot tub, workshop, or new kitchen appliances) at the same time as the panel upgrade, each new circuit adds $150 to $500 depending on the wire run distance and amperage.

You have a 60A or 100A panel and it's full. No open breaker slots means you can't add circuits for new appliances, a hot tub, or an EV charger without upgrading. Tandem breakers can buy you a few extra circuits, but they're a band-aid.

You're adding an EV charger. A Level 2 EV charger draws 30 to 50 amps. If your 100A panel is already loaded with air conditioning (30-40A), an electric range (40-50A), and a dryer (30A), there's not enough capacity for an EV charger without upgrading to 200A.

You have a recalled panel brand. Federal Pacific (Stab-Lok), Zinsco, and certain Challenger panels are known fire hazards. Breakers in these panels can fail to trip during an overload. Insurance companies are increasingly requiring replacement. Replacement is not optional — it's a safety issue.

Breakers trip frequently. If you're constantly resetting breakers, your circuits are overloaded. This might be solved by redistributing loads across circuits, but often the underlying issue is an undersized service.

You're doing a major renovation. Adding a kitchen, bathroom, or addition requires new circuits. If your panel doesn't have capacity, the upgrade should be done before or during the renovation.

An electrical panel upgrade is a 6 to 10 hour job for a licensed electrician, sometimes two electricians for the heavier work. Electricians charge $70 to $120/hour in most markets. At 8 hours average, that's $560 to $960 in labor alone — roughly 40% to 50% of the total project cost.

The work involves: coordinating the utility disconnect, removing the old panel and breakers, mounting the new panel, reconnecting all existing circuits, installing new breakers, connecting the service entrance, installing grounding, testing every circuit, and scheduling the inspection. It's precise, code-heavy work that requires a licensed electrician.

Panel upgrades range from $1,500 in lower-cost markets to $4,000+ in expensive metros. The biggest regional variable is electrician hourly rates: $60 to $80/hour in the Southeast and Midwest vs. $100 to $150/hour in California, New York, and New England. Permit fees also vary widely — $75 in some counties, $300 to $400 in major cities.

In areas with older housing stock (Northeast, parts of the Midwest), panel upgrades often uncover additional issues — knob-and-tube wiring, ungrounded circuits, aluminum wiring — that add cost. In newer construction areas (Sun Belt), the existing infrastructure is usually in better shape.

This is absolutely not a DIY project. Electrical panel work involves working with the service entrance — the highest voltage, highest amperage point in your home. The service entrance cables from the utility are always live (even when the main breaker is off) unless the utility disconnects them. Touching a live 200A service entrance cable can be fatal.

Beyond safety, permits and inspections require the work to be done by a licensed electrician in virtually every jurisdiction. DIY panel work will fail inspection and may void your homeowner's insurance. Some utility companies will refuse to connect service to unpermitted panel work.

The only legitimate way to save money is to get multiple quotes from licensed electricians and compare. Price differences of 30% to 50% between electricians for the same scope are common.

Before calling electricians, take a photo of your current panel with the door open (showing the breakers) and closed (showing the brand label). Note your current amperage (printed on the main breaker) and count the total breaker slots and open slots.

Get 3 estimates from licensed electricians. Each should include: panel brand and size (number of spaces), service entrance work (if needed), new breaker types (standard, AFCI, GFCI), permit fee, utility coordination, and whether they handle the inspection scheduling. Compare apples to apples — a quote using a 30-space panel is better value than a 20-space panel, even at a slightly higher price.

Ask about their timeline. Some electricians can do the upgrade in one day (power off for 6 to 8 hours). Others split it over two days. Know how long you'll be without power and plan accordingly.
