Your panel is the heart of your home’s electrical system. Every light, every outlet, every AC compressor, every charger — it all runs through that one gray box. So when it’s undersized or outdated, everything downstream feels it: breakers that trip for no reason, lights that flicker when the AC kicks on, that warm smell near the panel you really don’t want to investigate twice.
I get asked what a panel upgrade costs almost every week. Here’s the honest answer — the real South Florida numbers, what drives the price up and down, and when an upgrade stops being optional.
The short answer
For a typical South Florida home, a panel upgrade — usually going from 100 amps to 200 amps — runs about $1,500 to $3,500. That’s the full job: the new panel, breakers, labor, the permit, and the final inspection.
Can it land outside that range? Sure. A straightforward swap in a newer home with clean wiring and easy access can come in toward the low end. An older home that needs service entrance work, grounding corrections, or a panel relocation can push past $3,500. But $1,500 to $3,500 is where most of these jobs land, and any quote in that window deserves a look.
What actually drives the price
The panel itself isn’t the biggest cost — it’s the conditions around it. Here’s what moves the number:
- Amperage. Going from 100 to 200 amps is the standard move. Bigger jumps — 200 to 400 for a large estate, or a detached workshop — cost more because everything upstream gets heavier: wire, meter equipment, utility coordination.
- Panel location and access. A panel in a wide-open garage wall is a fast day. A panel buried behind a built-in closet in a condo, or one that has to be relocated to meet current code clearances, is a different job entirely.
- Service entrance condition. Sometimes the panel is fine but the wiring feeding it isn’t. In older South Florida homes — especially ones that still have aluminum branch wiring or original 1960s service cable — we find surprises when we open things up. A good estimate accounts for the likely corrections; a cheap one pretends they don’t exist.
- Permit and inspection. In Florida, a panel replacement requires an electrical permit and a final inspection. That’s non-negotiable, and any price that “doesn’t need a permit” is a price you should run from. I’ve written before about what permits protect you from — the permit is what makes the work real.
When an upgrade stops being a nice-to-have
You don’t upgrade a panel because you feel like spending money. You upgrade because the panel is telling you it can’t keep up. The signs:
- Breakers tripping regularly — not once in a blue moon, but as a pattern
- Lights dimming or flickering when a major appliance starts
- Buzzing or burning smells near the panel
- Warm breakers or a panel cover that feels hot
- A fuse box instead of breakers (yes, they’re still out there)
- Certain old panel brands — Federal Pacific and Zinsco panels are ones insurance companies flag by name
That last one matters more than people realize. Florida insurers are actively asking about panels. On four-point inspections for homes over 25 years old, the inspector reports the panel brand, age, and condition — and carriers will condition coverage on replacing problem panels. I’ve seen homeowners discover this the week before closing. If your insurance company is telling you the panel has to go, it’s not really a choice anymore — but doing it on your schedule, with a real estimate, beats doing it on their deadline.
The EV charger question
A lot of panel upgrades in 2026 start with a different purchase: an electric vehicle. A home EV charger typically needs a 240-volt dedicated circuit pulling serious amperage — and a 100-amp panel in a house with an electric range, electric water heater, and central AC often doesn’t have the room. Sometimes the answer is just a dedicated circuit off the existing panel. Sometimes the honest answer is that the panel needs to go first. That’s a calculation we run on every estimate where a charger is in the plan.
What upgrade day looks like
Power goes off — expect 4 to 8 hours without it for a standard upgrade, sometimes a full day with the utility coordination if the meter gets involved. We pull the permit, coordinate the inspection, swap the panel, re-label everything, test every circuit. By the end of the day, you’ve got a panel that will handle the next 25 years of whatever you plug into it.
The money side
A panel upgrade is a middleweight project — not pocket change, not a second mortgage. For bigger electrical work, we finance through Acorn Finance: smaller jobs from $120 a month, typical projects in the low $200s to $300s a month, with approved credit. Rates start as low as 4.49% APR with approved credit. And if your insurer is the one forcing the issue, ask me about timing — a new panel paired with impact windows is the one-two punch Florida carriers actually reward, and My Safe Florida Home has offered grants up to $10,000 for hardening work in the past.
FAQ
Do I need a permit to replace an electrical panel in Florida?
Yes. Panel replacements require an electrical permit and a final inspection under the Florida Building Code. The permit has to be pulled by a licensed contractor — and the inspection record is what protects you when you sell or file an insurance claim.
How long does a panel upgrade take?
Most residential upgrades finish in one day. Power is typically off 4 to 8 hours. If the meter or service entrance needs utility work, it can stretch into a second day.
Will a new panel lower my insurance?
Not directly like impact windows do — but Florida carriers can deny or condition coverage on certain old panels (Federal Pacific, Zinsco), and a clean four-point inspection with a modern panel keeps your policy options open. That’s worth real money.
Can I upgrade my panel myself?
No — and this isn’t a handyman job either. Panel work must be done by a licensed electrical contractor and permitted. Your home’s main panel is the single most dangerous electrical work in the house. Don’t.
Want a real number for your house?
Every panel is different — the brand, the age, what’s feeding it, what your house needs next. The only number that matters is the one for your home, after I’ve looked at the panel. That’s a free estimate. Onel Construction LLC (CGC1511492) serves Palm Beach, Broward, and Miami-Dade counties.
