Electrical Panel Replacement Cost in Louisiana: 100-Amp vs 200-Amp
Replacing an electrical panel in Louisiana usually runs from the low thousands for a straightforward like-for-like swap up to several thousand when you move from a 100-amp service to 200 amps and the utility connection has to change with it.
The panel itself is a small part of that number. Most of the cost is the labor, the permit and inspection, and whatever it takes to bring older wiring up to code once the cover comes off. Our electrical panel upgrade team gives you a firm price in person after we see the panel, because guessing over the phone helps nobody. Here is what actually shapes the bill.
100-amp vs 200-amp: which one do you need?
A 100-amp panel was standard for decades and still runs plenty of older Acadiana homes fine. The problem shows up when you add load the house was never built for: central AC, a tankless water heater, an EV charger, a hot tub, a workshop, or a kitchen full of modern appliances. That is when breakers start tripping and you run out of open slots.
A 200-amp service gives you the headroom for all of that with room to spare, which is why it has become the default for remodels and additions. If you are only replacing a failing panel and your usage is not changing, a 100-amp replacement can be the right call. If you are adding major loads or planning to, paying once for 200 amps beats paying twice.
Typical panel replacement price ranges
Use these as a rough guide for Louisiana, not a quote. Your home's age and setup move the number.
100-amp panel replacement, like-for-like: the low end, since the service size and meter usually stay the same.
Upgrade to 200-amp service: higher, because it involves a new panel, a new meter base, a heavier main feeder, and coordination with the utility.
Panel relocation: add to either of the above if the panel has to move to meet clearance rules or make room for a remodel.
Sub-panel add-on: a smaller separate cost when you need more circuits for a garage, shop, or addition rather than a full replacement.
What drives the cost of a panel job
The condition behind the cover
Louisiana homes throw surprises. We still find Federal Pacific Stab-Lok and Zinsco panels around Acadiana, both with a known failure history, plus aluminum branch wiring and undersized service in pre-1970 houses. If the wiring feeding or leaving the panel is unsafe, the honest fix is bigger than a simple swap. A cheap quote that ignores that is not really cheaper.
Permits and inspection
A panel replacement is permitted work that gets inspected. That is not padding, it is your protection and the law. A licensed electrician pulls the permit and schedules the inspection; an unlicensed one skips it and leaves you holding the risk if something goes wrong or you try to sell the house later.
The utility connection
Going from 100 to 200 amps often means the power company has to disconnect and reconnect the service, and sometimes upgrade the drop. That coordination adds time and cost, but it is what makes the bigger service safe and legal.
Whole-home rewiring in the mix
Sometimes a panel problem is really a wiring problem. If we find failing branch circuits, a full or partial house rewiring may be the smarter long-term spend. We will lay out both paths and the cost of each so you decide with the full picture.
Signs your panel is due
Breakers that trip for no clear reason
A panel that feels warm, smells hot, or buzzes
Fuses instead of breakers, or a Federal Pacific or Zinsco label
No open slots left and you keep needing more
Flickering lights across the house when big appliances kick on
Any one of these is worth an inspection. Two or more, and you should not wait.
Why "cheap" panel work costs the most
The panel is the heart of your home's electrical system. Cut a corner here and you are gambling with a fire risk, not just a repair. Every panel we replace is installed by a licensed, background-checked electrician to current code, permitted and inspected, and backed by our 5-year workmanship warranty on most repairs. When you compare quotes, make sure you are comparing permitted, licensed work, not a low number that leaves out the parts that keep your family safe. Financing is available on larger jobs so a safe panel does not have to wait.

Frequently asked questions
How long does a panel replacement take? Most standard replacements are a one-day job, though the power is off for part of it. An upgrade that involves the utility can stretch depending on their scheduling. We give you the timeline before we start.
Do I need a 200-amp panel? Not always. If you are adding central AC, an EV charger, a tankless heater, or a workshop, 200 amps is usually worth it. If your usage is not changing, a 100-amp replacement may be all you need. We size it to your actual home.
Is a permit really required to replace a panel? Yes. Panel work is permitted and inspected in Louisiana. If an electrician offers to skip the permit, treat that as a warning sign.
Can you replace a Federal Pacific or Zinsco panel? Yes, and we recommend it. Both have a documented failure history. If you have one, have it inspected and plan to replace it.
