People search for a panel replacement price expecting one number, and online ranges are so wide they do not help much. The reason is simple: "replace the panel" can mean swapping one box for another in an afternoon of work, or it can mean a new service from the meter to the last breaker. We do not quote panel work without seeing the panel, the meter and the service, and we do not publish prices. What we can do is explain what drives the scope, so the quotes you get make sense and you can compare them fairly.
Panel only, or the whole service?
This is the biggest single factor. A like-for-like panel replacement keeps the same service size and changes the panel and breakers. A service upgrade, for example from 100 to 200 amps, also changes the meter base, the main disconnect and the service conductors, and may need FPL to change its own equipment. Our guide to 100 vs 200 amp service explains how a load calculation decides which you need. Ask every contractor which of the two they are quoting.
The meter base and riser
Outside most Miami houses is a meter enclosure, often with a riser (the pipe carrying the service wires up the wall) or an underground feed. If it is rusted, damaged, too small for a new service, or a style FPL no longer accepts, it gets replaced too. Coastal salt air and decades of rain are hard on these parts; our guide to salt air corrosion shows what that looks like. Some homes have a combination meter and main outside and a separate panel inside, which changes what is replaced.
Permit and inspection
Panel replacement and service changes are permitted work, pulled by a licensed electrical contractor and closed with an inspection. Which building department you deal with depends on where the property is: the City of Miami, Miami Beach, Coral Gables, Pinecrest and others each run their own. Our guides to City of Miami electrical permits and Miami Beach electrical permits describe two of them. The permit is also the document your insurer will want later.
FPL coordination
Your electrician does the panel work, but FPL controls the power to the house. FPL's project types page says that when its equipment does not need upgrading, the job may only need a service disconnect and reconnect, and that it cannot reconnect until the local building department has inspected the work. Where FPL's own equipment has to change, that is a separate project on FPL's side with its own outage. Scheduling around both affects how the job is planned.
Grounding updates
A replaced service has to meet today's grounding requirements, not the ones the house was built under. That can mean new grounding electrode conductors, ground rods or connections to the water piping, and correcting neutrals and grounds that were combined where they should be separate. In an older house, this is often where the surprises are.
Code updates the work triggers
Replacing equipment brings it under the code in force now. One clear example: since the 2020 edition, the National Electrical Code requires a surge protective device on services supplying dwelling units, and says that where service equipment is replaced, the requirement applies, as Mike Holt's commentary on 230.67 explains. Our surge protection page covers what that device does. Other items depend on the job and the building department: labeling, working clearance in front of the panel, and how any circuits that are extended or modified are protected.
Location and access
A panel on an open garage wall is a different job from one buried behind built-in cabinets, in a closet with shelving, or in a spot that no longer has the working space the code requires. Moving a panel adds wiring to reach the new location. Finished drywall around a recessed panel has to be opened and patched. Flood elevation can also matter for equipment outdoors in some zones.
What is wrong inside
The number of circuits, the condition of the wires coming into the panel and what the old panel was hiding all affect the work. Brittle insulation, aluminum branch circuits, circuits doubled up under one breaker and wires too short to reach the new breaker positions each add time. See aluminum wiring in older Miami homes for one common case.
Condo or house
In a condo, the unit panel is usually the owner's, but the feeder and the building's meter room are usually the association's. Buildings often require an approval form, a certificate of insurance from the contractor, set work hours and elevator reservations, and a shutdown in a shared electric room may need building staff. Those all shape the schedule. Our guide to condo electrical repairs in Miami Beach covers who owns what.
The panel itself
Panel size, the number of spaces, whether you want room for future circuits and the type of breakers needed matter too. Circuits that need AFCI or GFCI breakers cost more per breaker than standard ones. Planning spaces now for an EV charger, a generator inlet or a mini-split can save a second job later. See generator installation and EV charger installation.
How to compare quotes
- Is it a panel replacement or a service upgrade? What size?
- Does it include the meter base, riser and grounding, or only the panel?
- Who pulls the permit, and who schedules FPL and the inspection?
- What happens if the old wiring needs work once the panel is open?
- What paperwork do you get at the end for your insurer?
A quote that answers all five is easier to compare than a single number.
Questions people ask
Can you give me a price over the phone?
Not for a panel. Photos of the panel, the label and the meter help us tell you what kind of job it is, but we quote after seeing it.
Is replacing a Federal Pacific or Zinsco panel different?
The process is the same. These panels are often old enough that the grounding and service around them need work too. See Federal Pacific panels.
Is it worth replacing the panel before I have to?
If an insurer, a planned load or warning signs are pointing that way, planning it on your schedule is easier than doing it against a deadline. Our 9 signs list helps you decide.
