What affects the cost?
- Amperage increase — jumping from 100A to 200A is standard; 400A upgrades for large homes or shops cost significantly more
- Code compliance — older panels may need grounding upgrades, AFCI/GFCI breakers, and updated wiring to meet current NEC requirements
- Location of the panel — exterior relocations or moving a panel to a new wall adds labor and materials
How to save on panel upgrade costs
- Get 3+ quotes — panel upgrade pricing varies 25–40% between electricians
- Combine with other electrical work — adding circuits during a panel upgrade is cheaper than a separate visit later
- Handle utility coordination early — meter and service upgrades from the utility can delay the project weeks; start early
- Check rebate programs — many utilities offer rebates for panel upgrades tied to electrification (heat pumps, EV chargers)
Frequently asked questions
Do I need to upgrade my panel?
Yes if: you have 100 amp service in a home built before 1980, you're adding AC/EV charger/hot tub, panel is rusty or has burn marks, or you have a Federal Pacific or Zinsco panel (these are fire hazards regardless of age). Modern homes with electric appliances should have at least 200 amp service.
How long does a panel upgrade take?
Most panel upgrades take 6–10 hours of work, but the project spans 1–2 days because power must be shut off, the utility has to disconnect/reconnect service, and inspection is required. You'll be without power for 4–8 hours during the actual upgrade.
