Cost by service scenario
Panel work is not one project. Swapping a panel on an existing service is a different job from raising the service capacity with the utility involved. Every row is priced against the St. Louis median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| Like-for-like panel replacement | Same amperage, existing service and meter reused | $1,900 – $2,800 |
| 100A → 150A upgrade | New panel and breakers, service conductors evaluated | $2,800 – $3,900 |
| 100A → 200A service upgrade | New panel, meter base, grounding and utility reconnect | $3,500 – $4,900 |
| 200A upgrade with mast/service entrance work | New riser or weatherhead, exterior conductors replaced | $4,600 – $6,300 |
| 400A service | Large home, dual panels or subpanel feed | $6,700 – $9,500 |
- • The utility, not the electrician, controls the disconnect and reconnect window — schedule slippage here is the usual cause of a two-day job becoming a week.
- • Meter base replacement, grounding electrode upgrades and bonding to water and gas are routinely quoted separately; ask for them line by line.
- • Federal Pacific, Zinsco and fuse panels are commonly flagged by insurers and four-point inspections, which is why many replacements are not optional.
- • Overhead-to-underground conversions add trenching and are priced by the foot.
- • If an EV charger, heat pump or solar is coming, size the service for it now — the second trip repeats the permit, the inspection and the utility coordination.
Basis: Each scope is priced as a multiple of the modeled St. Louis median for electrical panel replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Labor in the price
$2,100
60% of the median — the rest is material, disposal and permit.

Frequently asked questions
Do I need a permit to replace an electrical panel?
Yes, always. An electrical permit is required, a licensed electrical contractor must perform the work in most Florida jurisdictions, and the utility will not reconnect service until the final inspection passes.
How long does a panel upgrade take?
The physical work is usually one day with power off for 4-8 hours. Utility disconnect scheduling and inspection generally stretch the total to one to four weeks.
