How Much Does an Electrical Panel Upgrade Cost?

Upgrading a single-family home from a 100-amp panel to 200 amps, with the panel staying where it is, often clusters around $2,000–$4,200 in the US. The national spread is wider, about $1,500–$8,000, because the utility’s rules and the path of the service entrance can cost more than the panel hanging on the wall. This is a planning range, not a quote, and not a suggestion that you open the cover yourself.

The typical band fits a house that already has an overhead or short underground service, a panel location the inspector will still accept, and a utility that is not asking for a new meter location. If those are not your facts, budget toward the top of the spread until an electrician and the utility have both looked.

What the range includes

A straightforward upgrade includes the new panel, breakers to match the existing circuits, the mast or meter-base work the utility requires for that swap, grounding and bonding brought up to the current local reading of the code, a permit, and inspection. It assumes the circuits themselves are reusable.

It does not include rewiring the house, replacing aluminum branch wiring, adding a subpanel in a garage for a workshop, trenching a new underground lateral across a yard, or repairing a large area of siding and drywall because the old panel was buried in a remodel. Those are different projects that get stapled onto “panel upgrade” in casual estimates.

What moves the price

Driver	How it changes the bid
Utility rules	Some utilities charge a fee, require a new meter base, or will not reconnect until their crew is scheduled. That wait is not optional.
Service path	A rusted mast, an undersized riser, or a long underground run moves the job out of the typical band.
Panel location	Moving a panel out of a closet or a bathroom — places modern code will not accept — adds cable and finish repair.
Grounding	Old houses often need new grounding electrodes. It is ordinary work and it should be on the bid.
Condition of the old gear	Federal Pacific and Zinsco panels are replaced because of a safety record, not because 200 amps is fashionable. Identifying the brand is part of the quote.
New loads	An EV charger, a heat pump, or a tankless water heater may be why you are upgrading. The panel price is not the price of those appliances.

If you are pricing a heat pump or a kitchen at the same time, read the central air guide and the kitchen remodel guide as separate scopes that may force this one.

DIY or hire

Hire a licensed electrician. The service conductors on the utility side of the main breaker are energized when the main is off. Permits, utility disconnects, and inspection are part of the work, not paperwork you add later. A homeowner who is comfortable with electrical work can still be the person who labels circuits, clears the wall, and pulls finish materials — after the electrician says that help is useful.

Do not buy a panel at a home center and ask someone to “just land the wires.” The value of the job is the design of the breaker layout, the grounding, and a panel the inspector will sign.

Repair or replace

Replace or upgrade when you are adding loads the service cannot carry, the panel is a brand with a known failure history, breakers will not reset or are double-tapped beyond what the panel allows, or you can see heat damage. Also upgrade when an insurer or a buyer’s inspector has made the panel a condition, and a licensed electrician agrees the condition is real.

Do not replace a 200-amp panel that is listed, has spaces, and shows no heat damage just because the cover is ugly or the breakers are not the brand a salesperson prefers. Do replace a crowded panel that has no legal way to add a circuit you actually need — sometimes that is a subpanel, which can cost less than a service upgrade. Ask for both prices.

Frequent tripping is a clue, not a diagnosis. A tripping breaker can be a bad breaker, a failing appliance, or a circuit that was overloaded by a remodel. The panel is the answer only after someone measures the load.

How to use this number

Get two written bids that separate the electrician’s scope from utility charges, state the amp rating, say whether the panel moves, and list grounding work. A bid under the national spread may be a panel swap that assumes the utility equipment is already acceptable. Confirm that with the utility, not only with the low bidder.

A bid over the spread should name the mast, the trench, the relocation, or the finish repair that caused it. Bring that scope to the second electrician so you are comparing the same job. Background on how this site sets bands is on the methodology page.
