What does an electrical panel upgrade actually cost in 2026? Real pricing by amperage, plus what older homes in RI and SE Massachusetts need to know.
Your electrical panel is the box that distributes power from the utility line to every circuit in your house. Most owners never think about it until something forces the issue: a home inspector flags it, a fuse box can't support a new AC unit, or an insurer won't renew a policy. The size of the upgrade (measured in amps) and the condition of your existing service are the two biggest factors in what you'll pay.
Here's what panel upgrades typically cost in 2026, fully installed:
| Upgrade Type | Installed Cost | Typical Timeline |
|---|---|---|
| 100 Amp Panel (replace/upgrade) | $850 – $1,600 | 1 day |
| 150 Amp Panel | $1,100 – $2,200 | 1 day |
| 200 Amp Panel | $1,300 – $3,000 | 1 day |
| 400 Amp Panel (or dual 200A) | $2,000 – $4,500+ | 1–2 days |
| Fuse Box to Breaker Conversion | $1,500 – $3,500 | 1 day |
| Subpanel Addition | $500 – $1,800 | Half day |
The most common job, moving from an old 100-amp panel to a 200-amp panel, lands between $1,300 and $3,000 including the new panel, breakers, and labor. You'll pay more if the service entrance (the wiring and equipment connecting your home to the utility line) also needs to be replaced, if the panel has to be relocated, or if your municipality's permit fees run high.
100 amps is the minimum most local codes allow for a modern home, and it's still enough for smaller houses without central AC, an electric range, or an EV charger. If you're just replacing an aging 100-amp panel with a new one of the same size, this is the cheapest path. But if you're planning any electrification in the next several years, most electricians will talk you into 200 amps instead. The cost difference is small enough that it's usually worth it.
150 amps is a middle-ground size that shows up in some mid-century homes and additions. It's less common as a target for new installations since the cost difference between 150 and 200 amp equipment is small, but it's a reasonable upgrade if your existing service wiring can't support a full 200-amp load without additional work.
200 amps is the standard for new construction and the most common upgrade target for older homes today. It comfortably supports central air conditioning, an electric water heater, a modern kitchen, and typically one EV charger or heat pump, with some room to spare. If you're upgrading anyway, most electricians recommend going to 200 amps rather than 150. The incremental cost is modest compared to upgrading again in five years.
400-amp service is usually installed as two 200-amp panels rather than a single 400-amp unit. It's for larger homes going all-electric: heat pump, EV charger, pool, electric cooking, the works. Overkill for most single-family homes. If your electrician is quoting 400 amps and you don't have a specific reason, ask whether 200 amps with room to grow would be enough.
Homes built before the 1960s often still have fuse boxes rather than modern circuit breaker panels. Converting to breakers means replacing the entire panel, not just swapping parts, which is why this runs higher than a like-for-like breaker panel replacement. Many insurance companies now decline to write or renew policies on homes with active fuse boxes, which is the single most common reason homeowners get this work done.
Going from 100 to 200 amps costs more than a like-for-like 100-amp swap because it usually requires a larger meter socket, heavier service entrance cable, and sometimes a larger conduit or mast. The jump from 200 to 400 amps is a bigger step still, often requiring two panels or specialized equipment.
The service entrance is the weatherhead, mast, meter socket, and the cable running from the utility line to your panel. All of it has to be sized for the new amperage. If yours is old, corroded, or undersized, it gets replaced alongside the panel, adding $800 to $2,000.
Converting from fuses to breakers is more involved than replacing an existing breaker panel because the entire enclosure, bussing, and often the grounding system need to be brought up to current code, not just the individual components.
If your panel is behind finished walls, in a tight crawlspace, or in a spot that no longer meets code (bathrooms and closets are common offenders), relocating it adds $500 to $1,500 in labor, wiring, and sometimes drywall repair.
Every panel upgrade requires an electrical permit pulled by a licensed electrician, plus an inspection from the local wire inspector before the utility will reconnect power. Permit fees run $100 to $500 depending on the municipality. This should be included in any quote you receive. If it's not broken out, ask.
The utility company has to disconnect and reconnect service as part of most panel upgrades, and in some cases has to approve or upgrade the transformer or drop line feeding your home. This is usually handled by your electrician but can add scheduling time, and occasionally cost, to the project.
Older homes often have grounding that doesn't meet current code: missing ground rods, no bonding jumpers, or connections that have corroded. Fixing this is usually bundled into the panel upgrade and adds $200 to $600.
Get at least three quotes. Panel upgrade pricing varies more than almost any other electrical job because scope differs so much between homes. One house needs the service entrance replaced, another doesn't. Three quotes gives you a real sense of what your specific job should cost.

If you're upgrading at all, go to 200 amps. The cost difference between 150 and 200 amp equipment is small relative to labor, and 200 amps covers an EV charger or heat pump down the road without another upgrade.
Bundle with other electrical work when you can. If you're already having an electrician on site for a kitchen remodel or heat pump install, doing the panel at the same time saves on a second trip and inspection.
Check for rebates before you pay. Some utility programs offer incentives toward panel upgrades when the work is required to support a heat pump or EV charger. Ask your electrician or utility what's available. And make sure every quote you compare includes the permit and inspection fee, not just labor and materials.
Rhode Island and southeastern Massachusetts have some of the oldest housing stock in the country. Panel upgrades are more common here than in newer housing markets, and they tend to be more involved too. A large share of homes in Providence, Pawtucket, Woonsocket, Fall River, and New Bedford were built before 1960 and still have original fuse boxes or early breaker panels well past their practical lifespan.
Labor rates for licensed electricians in the region run 15–25% above the national average, consistent with other trades in the area. Every municipality in Massachusetts and Rhode Island requires a permit for panel work, pulled by your electrician, with a mandatory inspection by the local wire inspector before the utility will restore power — budget $100 to $300 for this locally, though it varies by city and town.
Homes with knob-and-tube wiring remnants or original 1940s–1960s service equipment often need the full service entrance replaced, not just the panel. That pushes a lot of local jobs toward the higher end of the national range.
The other factor is electrification. More homeowners in the region are adding heat pumps (see our HVAC cost guide) and EV chargers, which means panel upgrades are increasingly a prerequisite rather than a standalone project. Mass Save and Rhode Island Energy both have efficiency programs that sometimes cover part of the panel work when it's required for a qualifying heat pump install. Ask before you assume you're paying the full tab.

Anywhere from $850 to over $4,000, depending on the amperage and how much of the existing equipment needs to come out. A straight 100-amp swap is the cheapest ($850–$1,600). The 200-amp upgrade most people get runs $1,300–$3,000. Fuse box conversions fall in the $1,500–$3,500 range because more of the old equipment has to go.
Yes, always. Your electrician pulls the permit and schedules the inspection with the local wire inspector. The utility won't reconnect power until the inspection passes. Budget $100–$500 for the permit fee itself, though your electrician should include this in the quote.
If you're planning to add central AC, an EV charger, a heat pump, or an induction range and you're already at or near capacity on your 100-amp panel, that's the clearest sign. Breakers tripping regularly, lights flickering when the dryer kicks on, or a panel that feels warm are other red flags.
Usually, yes. The practical issue is insurance: many carriers won't write or renew a policy on a home with an active fuse box. It also comes up during home sales. The conversion runs $1,500–$3,500 and you get a safer, more convenient panel out of it.
One day for most jobs. Your power will be off for a few hours during the swap itself, not the full day. If the service entrance also needs replacing or the panel is being relocated, it can stretch to two days.
