Panel Upgrade Cost 2026: 100 to 200 Amp ($2,000–$4,200)

Upgrading a single-family home from about 100 amps to 200 amps — panel staying where it is, breakers for the circuits you already have, grounding brought up to the local code, a permit, and ordinary utility coordination — often clusters around $2,000–$4,200. That figure is the full service upgrade in the table. The wider national spread, about $1,500–$8,000, covers a same-location swap the utility already accepts at the low end, and a new mast, a meter move, a short underground change, or heavy finish repair at the high end. A long trench, overhead converted to underground, a 400-amp service, or a rewire of the house can clear that spread. These are typical planning ranges, not a survey and not a quote.

The carton price of a panel is not the job. A 200-amp panel at a home center is often a few hundred dollars. The bid is the permit, the utility disconnect and reconnect, the grounding, the breaker layout, and whatever the service entrance has to become before the utility will energize it. Price the service you have, not the metal box.

The rows below are ways to read one job. They are not added together. A same-amp swap, a panel-only 200-amp change, and a full 100-to-200 service upgrade are three different scopes. Use the row that matches the work. Trenching is an add-on when the service has to go underground. A 400-amp service takes the place of the 200-amp row. A subpanel is a different project, for a service that can already carry the load. The permit is already inside the installed ranges.

Scope	Typical planning range
Same-amp panel swap	$1,500–$2,800
Panel-only, 200 amp	$1,800–$3,200
Full service upgrade, 100 to 200 amp	$2,000–$4,200
Trenching or underground, add-on	$1,500–$4,000
400-amp service	$6,000–$14,000
Subpanel	$900–$3,500
Permit	$50–$300

A same-amp swap replaces the panel at the amperage you already have. A failed 200-amp panel, or a Federal Pacific or Zinsco panel on a service that can already carry the house, is that row. It sits toward the floor of the national spread when the meter and the mast can stay.

Panel-only 200 amp means the electrician sets a 200-amp panel, breakers for the existing circuits, and the grounding, and the meter, the mast, and the utility equipment can already accept 200 amps. The power company may still pull the meter. It is not rebuilding the service. That row often lands under a full upgrade, and a high-labor city can push it into the typical band.

The full service upgrade is the $2,000–$4,200 band: about 100 amps to 200, panel in the same place, with the mast, meter, and utility coordination that increase requires. A rusted mast, a meter that has to move a few feet, or a panel that has to come out of a closet sits at the top of the band and leaves it when the path of the service changes.

Add the trenching row only when the lateral has to be underground. A short run in open soil is the low end. A long run, rock, or a bore can clear $4,000, and stacked on the service row it can clear the $8,000 top of the wider spread. Use about $15–$40 a foot as a planning allowance for open trench, conduit, and backfill. That allowance is the ditch, not the service cable and not the panel. A 400-amp service is its own project, often $6,000–$14,000, and it commonly clears the 200-amp spread. A utility transformer contribution or a long underground lateral can clear the 400-amp row as well.

An ordinary residential permit is often about $50–$300 and already sits inside the installed rows. Ask for it as its own line anyway.

What the range includes

The typical $2,000–$4,200 band assumes an existing single-family home and a main panel going from about 100 amps to 200 amps — or a fuse box, or a smaller panel with no legal spaces, going to 200 — in a location the inspector will still accept. It includes the new panel, breakers to land the existing circuits, the mast or meter-base work the utility requires for that increase, grounding and bonding updated for the local code, a permit, and inspection. It assumes the branch circuits themselves are reusable and a truck can reach the meter.

A same-wall upgrade in a lower-cost area, with an overhead service the utility already accepts, sits toward the lower half. A rusted mast or a meter that has to move sits at the top of the band.

The floor of the national spread, near $1,500, is the same-amp or same-location panel change where the meter, the mast or the short underground riser, and the grounding are already in a condition the utility will accept. The top, toward $8,000, is where a new mast and weatherhead, a meter-main the utility now requires, a panel moved out of a forbidden location, new grounding electrodes, and a real patch of siding or drywall usually land together. A long trench, overhead converted to underground, or a service above 200 amps can clear that top. Treat a number above it as a different scope and ask which driver caused it.

None of the bands include a whole-house rewire, replacement of aluminum branch wiring or knob-and-tube, a subpanel and new circuits for a workshop, a Level 2 EV charger, a roof-mounted solar array, a heat pump, or a tankless water heater. Those are the reasons people upgrade, and they are separate projects. Price a new air conditioner on the central air guide. Price a gas furnace on the furnace replacement guide. Price a tankless water heater on the tankless guide. Price a heat-pump water heater on the water heater guide. A kitchen that needs dedicated circuits is the kitchen remodel guide. Keep the appliance on its own line, and keep the panel on its own line.

Panel-only or a full service upgrade

Panel-only is the electrician’s scope when the service equipment can already take 200 amps and the panel itself is what changes to 200. The new panel, the breakers, the grounding, the permit, and a meter pull are the work. The utility is not installing a larger drop, a new transformer, or a new lateral. A house built with a 200-amp meter and a smaller panel is the usual case. Replacing a panel and staying at the amperage you already have is the same-amp row instead. The typical planning range for panel-only is $1,800–$3,200.

A full service upgrade is the job when the house is on about 100 amps, or on a 60-amp fuse box, and the service entrance has to become 200 amps before the utility will treat it as 200. The mast or weatherhead, the meter base or a meter-main, the service entrance conductors, and the utility’s coordination are in the $2,000–$4,200 band when the panel stays on the same wall. The gap between the two bids is that service-entrance work and the utility’s fee. It is not a more expensive breaker brand.

Ask for a panel-only price and a full service price when nobody has looked at the meter yet. The invoice should say which row it is. A 200-amp panel on a service the utility will not energize at 200 amps is a full upgrade, whatever the proposal calls it.

A 200-amp panel for an EV or a heat pump

You need 200 amps when a load calculation says the service cannot carry the new equipment together with the loads you already run. The name of the appliance does not decide it.

A Level 2 charger is a continuous 240-volt load, commonly a 40- or 50-amp circuit. The charger install, on a panel that already has capacity and space, is the EV charger guide, often a different $1,200–$2,500 job. A roof array has its own price on the solar panel guide. A ducted heat pump has its own circuit and its own price on the heat pump guide. Folding any of them into the panel bid hides the separate price.

A 100-amp house that already runs an electric range, a dryer, and central air often fails the calculation once a charger or a heat pump is added, and it fails more often if both are added. A house with gas heat, a gas range, and a gas dryer sometimes has room for one of those loads on 100 amps. Spare breaker spaces are not spare amperage. The calculation is the test.

A subpanel, typically $900–$3,500 on a short run, adds breaker spaces in the garage or a workshop. It does not turn 100 amps into 200. Use it when the service can already carry the load. Upgrade the service when the calculation fails, or when the main panel is obsolete, heat-damaged, or has no legal space for the new breaker.

Utility fees and rebates

Some power companies swap the meter at no separate charge once the electrician has set a meter base or a meter-main they accept. Others bill a connection fee or a service-upgrade fee, and they will not reconnect until their own crew is scheduled. When the transformer, the overhead drop, or an underground lateral has to be built, that utility charge is often a few hundred dollars and can run higher. It is not the electrician’s margin. The fee and the wait belong on the bid as their own line. Rules differ by company. Get the utility’s requirement in writing before you treat two bids as the same scope.

A rebate, where a utility or a state program offers one, is usually tied to an EV charger, a heat pump, or another electrification project. A panel swap by itself often does not qualify. The rebate is a separate application with its own deadline and its own inspection. These ranges do not subtract it. Ask for a bid that still shows the full price, and treat a rebate you have not received as money you do not have yet.

What moves the price

Driver	How it changes the bid
Utility rules	A meter swap at no charge keeps the job in the panel-only or full-upgrade row. A fee, a new meter-main, or a transformer contribution is its own line, and the wait is not the electrician’s margin.
Service path	A rusted mast, an undersized riser, or a weatherhead that misses the required clearance moves a same-wall upgrade toward the top of $4,200 and past it. Underground work is the $1,500–$4,000 add-on.
Panel location	A panel in a closet, a bathroom, or over the stairs often has to move. The move adds cable, a new route, and finish repair, and it can leave the typical band.
Grounding	Old houses often need a grounding electrode or a bonding jumper that was never there. It belongs on the bid. It is ordinary work, and it shows up when the inspection fails if it was left out.
Old equipment	Federal Pacific and Zinsco panels are replaced because of a known failure record. A same-amp swap is the $1,500–$2,800 row when capacity is already enough. A fuse box with no spaces is a capacity problem.
New loads	An EV charger, a heat pump, a tankless water heater, or a workshop may be why you are upgrading. Each one has its own price.
Finish repair	Opening siding, stucco, or a finished wall to move the panel is labor and a patch. A same-wall swap on open framing is a smaller day.

If the upgrade is happening because a kitchen remodel or a new air conditioner will not pass on the existing service, say so at the start. The electrician can size the service for the loads you are actually adding. A 200-amp panel that is listed, has spare spaces, and shows no heat damage does not need to be replaced because a salesperson prefers another breaker brand.

DIY or hire

Hire a licensed electrician. The service conductors on the utility side of the main breaker stay energized when the main is off. The permit, the utility disconnect, and the inspection are the work. A homeowner can label every circuit before the crew arrives, clear the wall, and put finish materials back after the inspector signs, once the electrician says that help is useful.

The $200–$600 shelf price is the panel. Landing those wires, sizing the grounding, and standing in front of the inspector are the installed ranges above. Many jurisdictions will not let a homeowner pull a permit for a service change. Where an owner is allowed to pull one, the utility still decides who may reconnect the service.

Adding a listed device on an existing circuit, where local rules allow an owner to do that work, is a different project. Double-tapping a breaker to make space, or rearranging breakers in a live panel, is how heat damage starts.

Repair or replace

Replace a Federal Pacific or Zinsco panel. Both lines have a long record of breakers that do not trip and of damage at the bus, and insurers and buyer’s inspectors often treat the name on the cover as a condition. A licensed electrician should confirm the brand and look for heat damage. A same-amp swap, typically $1,500–$2,800, is the right row when the service can already carry the house. A full upgrade to 200 amps, typically $2,000–$4,200, is the right row when you are adding an EV charger, a heat pump, or other load the calculation will not accept.

Upgrade as well when breakers will not reset or are double-tapped beyond what the panel listing allows, you can see heat damage or melted insulation, or a 60-amp fuse box is feeding central air and a dryer. Keep a listed panel that has legal spaces and shows no heat damage. A crowded panel that only needs more spaces, on a service that can already carry the load, is often a subpanel at $900–$3,500, which can cost less than a service upgrade. Ask for both prices.

A new 200-amp panel does not fix a loose connection in a junction box, and it does not replace aluminum branch wiring or knob-and-tube. Those are rewires. Frequent tripping is a clue. A breaker can trip because the breaker is bad, an appliance is failing, or one circuit is overloaded. If the water heater or the air conditioner is the thing that trips, price that equipment before you price a service change.

How to use this number

Ask for two or three written bids that name the row: same-amp swap, panel-only 200 amp, or full 100-to-200 service upgrade. Each bid should separate the electrician’s scope from utility charges, state the amp rating, say whether the panel stays or moves, list the grounding work, and say whether a mast, a meter-main, or a trench is included. Compare a full 100-to-200 upgrade with $2,000–$4,200. Compare a panel-only change with $1,800–$3,200. Compare a same-amp swap with $1,500–$2,800. Put trenching on its own line at $1,500–$4,000, and treat 400 amps as the $6,000–$14,000 project.

A very low bid is a reason to ask whether the utility fee, the grounding, and the permit are included. A high bid should name the mast, the trench, the relocation, or the finish repair. Two or three local bids on the same scope are the number that matters. How this site sets the band is explained on the methodology page.
