Cost to Replace or Upgrade an Electrical Panel (2026)
Electrical panel replacement and upgrade costs in 2026 — 100A to 200A, the signs you actually need it, and why a recalled or Federal Pacific panel can't wait.
The electrical panel is the heart of your home's wiring — the box where utility power splits into the circuits that feed every outlet, light, and appliance. Replacing one is a job homeowners run into for two very different reasons: either the panel is unsafe (old, recalled, or failing), or it's too small for a new load like an EV charger or a heat pump. This guide breaks down what a panel replacement actually costs in 2026, what moves the price, and how to tell which of those two situations you're in.
The short answer
A 2026 electrical panel replacement typically costs $1,200 to $4,500, with most homeowners paying about $2,500 to $3,000. A like-for-like 100-amp swap is the low end; a 200-amp service upgrade — the most common job — usually runs $2,000 to $4,500. Large or complex jobs (400-amp service, a long wire run, or a relocated panel) can reach $6,000 to $9,000+.
The panel box itself is the cheap part — typically $50 to $400 depending on amperage and brand. Almost everything you pay for is labor, materials around the panel (the meter, mast, grounding, and heavier service conductors on an upgrade), the permit and inspection, and the utility coordination to safely disconnect and reconnect power. That's why a "simple" panel turns into a four-figure project.
Panel replacement cost by amperage
These are typical installed 2026 ranges, including a standard permit and inspection. Where the work is just swapping the panel on the same service, you're at the low end; where it's a true service upgrade (new meter, mast, grounding, and heavier wire from the street), you're toward the high end.
| Service size | Typical cost | When you need it |
|---|---|---|
| 100A — like-for-like swap | $1,200 – $2,800 | Replacing a healthy-size but old/recalled panel; smaller home with gas appliances |
| 150A — upgrade | $1,800 – $3,800 | A middle step; some homes adding moderate electric load |
| 200A — upgrade | $2,000 – $4,500 | The standard modern service; EV charger, heat pump, electric range, remodel |
| 400A — upgrade | $4,000 – $9,000+ | Large or all-electric homes, workshops, or two-panel setups |
A few things this table can't show that swing your number: a panel mounted far from the meter (long, expensive wire run), a panel that has to be relocated to meet code clearances, an outdoor or buried-service install, and regional labor rates. Always get the cost broken out by line item so you can see what you're actually paying for.
Does the panel brand change the price?
The brand matters far less than the amperage and the labor — the box is a small slice of the bill — but a few names dominate residential work, and the breakers (not the empty enclosure) are where brand cost adds up, because each panel only accepts its own line of breakers.
| Brand | Reputation | Panel-only parts (200A) |
|---|---|---|
| Square D (QO / Homeline) | The contractor default; QO is premium, Homeline is value | $100 – $350 |
| Eaton (Cutler-Hammer) | Widely stocked, strong all-rounder | $100 – $300 |
| Siemens | Common, often the budget-friendly option | $90 – $250 |
| GE / ABB | Long-established, broadly available | $100 – $300 |
| Leviton / Schneider smart panels | App-controlled, per-circuit monitoring | $300 – $1,500+ |
Don't choose on box price alone. Ask which line the electrician stocks and warranties, and remember that AFCI/GFCI breakers, which modern code requires across much of the home, cost $40–$60 each and can add up to more than the panel itself on a fully populated new install. A "smart" panel costs much more up front but can be worth it if you want per-circuit energy data or plan to add solar, a battery, or EV charging you want to manage.
What about a subpanel instead?
If your main panel is out of slots but not out of capacity, a subpanel is often the cheaper fix — typically $500 to $2,000 installed. It's a smaller breaker box fed from your main panel by a single feeder, giving you a local cluster of circuits for a garage, finished basement, addition, or workshop. A subpanel doesn't add amperage to your home; it borrows from what the main panel already has, so a load calculation still has to confirm your service can spare the load. If that calculation shows the service itself is maxed out, you need a service upgrade, not a subpanel.
Where the money actually goes
A panel quote isn't one number — it's a stack of parts and labor. Understanding each line tells you whether a bid is complete or quietly hollowed out.
- Labor (the biggest share): A panel change is skilled, permitted, hazardous work. Most of your bill is the electrician's time, typically a 4-to-8-hour day for a swap and longer for a full service upgrade.
- The panel and breakers ($50–$400+): The enclosure plus the breakers that populate it. Modern code requires more AFCI and GFCI protection than old panels had, and those breakers cost more than plain ones — a real line item on a from-scratch panel.
- Meter base, mast, and weatherhead: On a service upgrade, the meter socket and the mast/conduit that carries the service wires often get replaced too, because the old ones aren't rated for the new amperage.
- Grounding and bonding: Heavier service requires a proper grounding electrode system (ground rods or a connection to the water line and a supplemental electrode). Older homes frequently fail here and need it brought up to code.
- Service conductors: Going from 100A to 200A means the wires from the meter to the panel — and sometimes from the utility's drop — must be upsized. Copper or aluminum, gauge, and length all matter.
- Permit, inspection, and utility coordination ($100–$500+): The building department permit and inspection, plus the power company's disconnect/reconnect and re-metering. Non-negotiable on a safe, legal job.
- Drywall and finish: If the panel moves or the wall is opened, patching and painting are extra.
Is your panel a safety problem or a capacity problem?
This is the single most useful question to answer before you spend a dollar, because the two situations have very different urgency.
Replace it now — safety
These are fire and shock risks, not upgrades
- Federal Pacific (Stab-Lok) or Zinsco / Sylvania panel — breakers that can fail to trip.
- A fuse box instead of breakers (often 60A, common before 1965).
- Rust, scorch marks, a burning smell, buzzing, or a warm panel cover.
- Breakers that trip constantly or won't reset, or that feel loose.
- Aluminum branch wiring at the panel, or any double-tapped breakers.
Upgrade it soon — capacity
Driven by what you're adding, not by danger
- Adding an EV charger, heat pump, electric range, or hot tub.
- A kitchen remodel, addition, or finished basement that adds circuits.
- The panel is full — no open slots — and you keep adding tandem breakers.
- You're going all-electric and a load calculation shows you're near the limit.
If anything in the left card describes your panel, treat it as a repair to schedule, not a project to mull over. If only the right card applies, you have time to plan, get three bids, and combine the upgrade with the project that's driving it.
Recalled panels: why FPE and Zinsco can't wait
Federal Pacific Electric Stab-Lok breakers, made from roughly 1950 to 1980, were found to fail standard Underwriters Laboratories calibration tests — meaning a breaker can fail to trip during an overload or short, the exact moment it's meant to protect you. In 1980 the manufacturer reported to the U.S. Consumer Product Safety Commission that many breakers didn't comply with UL requirements, and CPSC testing confirmed the failures. A 2002 New Jersey court found the company had knowingly distributed breakers not tested to the UL standard their labels claimed. Zinsco (and rebadged Sylvania) panels of the same era have a parallel reputation for breakers that melt to the bus bar and stop tripping. Home inspectors and electricians routinely advise replacing both — see our guide to the electrical warning signs you should never ignore.
How big a panel do you actually need?
Amperage is the panel's capacity. The right size is a load calculation, not a guess — an electrician totals your real demand against the panel's rating. As a practical guide:
| Service | Good for | Watch out when |
|---|---|---|
| 100A | Smaller home, gas heat/water/range, modest electric load | You add an EV charger + heat pump, or go all-electric |
| 150A | Mid-size home, some electric appliances | A 400V workshop or two EVs |
| 200A | The modern default — central air, electric range, EV charger, remodels | Whole-home electrification at the high end |
| 400A | Large or all-electric homes, ADUs, big shops | Rarely needed for an average home |
The practical takeaway: most homes built or renovated today go to 200 amps because electrification keeps pushing demand up, and the extra cost to go from 100A to 200A while the panel is already open is usually small compared to doing it as a separate job later. If you're weighing whether to replace an aging system now or wait, the repair-or-replace calculator can help you frame the timing.
The maintenance and inspections that prevent an emergency replacement
A panel rarely needs replacing on a schedule — it needs replacing when it becomes unsafe or maxed out. A few inexpensive habits catch problems while they're cheap, and turn a 2 a.m. emergency call into a planned project.
| Task | How often | DIY cost | Pro cost | Prevents |
|---|---|---|---|---|
| Electrical panel inspection | Every 3–5 years, or at purchase | $0 (visual) | $150–400 | A recalled or failing panel going undetected until a fire |
| Test GFCI/AFCI breakers & outlets | Monthly | $0 | $80–150 | A dead safety device you only discover during a fault |
| Replace a single faulty breaker | As needed | — | $120–300 | A bad breaker overheating the bus and damaging the panel |
| Whole-home surge protection | One-time | — | $200–500 | A surge frying electronics and panel components |
| Address constant tripping early | As needed | $0 (diagnose) | $150–600 | An overloaded circuit becoming an arcing fire hazard |
If your breaker keeps tripping, don't just keep resetting it — that's the panel telling you something. Work through the causes in why a circuit breaker keeps tripping and why a GFCI keeps tripping before assuming you need a whole new panel; sometimes it's one circuit, not the box.
Red flags in a too-cheap bid
When one quote comes in well below the rest, it's usually a smaller scope, not a better deal. Watch for the corners that get cut:
- No permit pulled — the single biggest red flag. Unpermitted panel work can void your insurance and fail at resale.
- Reusing the old meter base, mast, or grounding on a service upgrade that should replace them.
- No load calculation — sizing the panel by eyeball instead of code math.
- An unlicensed or uninsured "handyman" doing work that legally requires a licensed electrician in most places.
- No itemized breakdown — a vague lump sum is where skipped grounding and a too-small service hide.
Get at least three itemized bids, confirm the electrician is licensed and insured, and make sure the permit and utility coordination are written into the price. For the broader picture of what electricians charge by the hour and by the job, see the electrician cost guide.
Bundle it with the project that's driving it
If a remodel, an EV charger, or a heat pump is the reason you're upgrading, do the panel as part of that project, not as a separate trip. The electrician is already on site, the permit can cover both, and you avoid paying twice for setup and utility coordination. A common pairing is a Level 2 EV charger plus a 200-amp service upgrade — bundled, it's far cheaper than charger now, panel later.
Rebates, tax credits, and bringing the cost down
A panel upgrade is one of the few four-figure home projects that used to come with a federal tax break — and may still come with local help. Here's the honest 2026 picture:
- The federal tax credit has expired. Under the Energy Efficient Home Improvement Credit (Section 25C), a panel rated 200 amps or more that supported qualifying energy property counted as an eligible electrical component worth 30% of its cost, up to $600. But that credit only covered work placed in service through December 31, 2025. If your panel goes in during 2026, don't budget for it — many cost guides still quote it as if it's live, and it isn't.
- Utility and state rebates often still apply. Many electric utilities and state energy offices offer rebates when a panel upgrade enables electrification — a heat pump, heat-pump water heater, or EV charger. These can be worth hundreds to low thousands and are stackable with the project they support. Check your utility's website and your state energy office before you sign.
- Mind how rebates interact. A rebate that's tied to the cost of the work reduces the amount any remaining credit is calculated on, so confirm the order with your tax preparer.
- The cheapest dollar is the one you don't spend twice. Bundle the panel with the project driving it, get three itemized bids, and right-size the service with a load calculation rather than over-buying 400A you'll never use.
For a wider view of how this fits a maintenance budget, the repair-or-replace calculator helps you decide whether to do it now or stage it.
