Electrical panel upgrade cost in 2026
How do you know when 100A stops being enough? Usually right when you're planning an EV charger or an addition. A panel upgrade typically costs $1,300–$4,000 — here's what a 200A upgrade actually involves, and the signs it's time.
Electrical panels rarely fail outright — they just become undersized as homes add air conditioning, EV chargers, hot tubs and home offices. A panel upgrade is one of the least glamorous home investments, but it's often the thing that quietly gates every other electrical project you want to do.
What it costs
Signs your panel is undersized
- Breakers trip regularly, especially when running multiple large appliances at once.
- Your panel is still 60A or 100A and you're adding an EV charger, hot tub, or major electric appliance.
- You have a fuse box instead of breakers — most insurers and many lenders flag this on older homes.
- Lights flicker or dim when large appliances start up.
- You're planning solar — many installations require a panel with enough capacity and often a specific "solar-ready" busbar rating.
Unlike cosmetic upgrades, an undersized panel is a genuine safety and capacity limit. If you're planning an EV charger, solar, a heat pump, or a major addition, get the panel evaluated first — it often turns out to be the actual bottleneck, not the headline project.
What drives the price
- Amperage jump. Larger jumps (60A to 200A) cost more than incremental ones (100A to 150A).
- Utility coordination. Some upgrades require the utility to disconnect and reconnect service, which can add scheduling time and minor fees.
- Permit and inspection. Panel work almost always requires a permit and inspection — a contractor skipping this is a red flag, not a cost saving.
- Panel location and access. An easily accessible panel is cheaper to work on than one buried behind finished walls or in a cramped space.
What actually happens on upgrade day
- Utility coordination beforehand (scheduled days to weeks in advance). For upgrades that require a meter swap or service disconnect, your electrician coordinates a shutoff window with the utility — this scheduling, not the work itself, is often the longest part of the timeline.
- Power shutoff (start of the work day). The utility or electrician disconnects power before any panel work begins, for safety.
- Old panel removal and new panel installation (3–5 hours). The panel is swapped, circuits are transferred to the new breakers, and the new service capacity is wired in.
- Reconnection and testing (1–2 hours). Power is restored circuit by circuit and tested before the crew leaves.
- Inspection (separate visit, typically within a week or two). A local inspector verifies the work before it's considered complete and code-compliant.
Power is typically out for most or all of the work day — plan around that, especially for anything requiring refrigeration or medical equipment.
Why this isn't a DIY job
Panel work is not a DIY project, full stop. You're working on the point in your home's electrical system with the highest fault current and the least room for error — mistakes here carry fire and electrocution risk, and in nearly every jurisdiction, panel work legally requires a licensed electrician and a permit regardless of the homeowner's skill level. There's no meaningful DIY-savings lane here the way there is for, say, painting or flooring; the entire job should go to a licensed pro.
Mistakes that inflate the price or create risk
- Undersizing for future needs. If an EV charger, solar, or a major addition is even a few years out, upgrading to a size that only meets today's needs often means paying for a second upgrade later.
- Skipping the permit. Beyond the legal risk, an inspection is the only independent check that the work was done safely — skipping it to save time or a fee isn't a real saving.
- Ignoring old wiring elsewhere in the house. A new panel doesn't fix outdated or unsafe wiring downstream of it; if your home has old wiring types with known issues, mention it to your electrician during the panel job rather than treating them as separate problems later.
- Choosing the cheapest bid without checking licensing. Given the safety stakes, verifying a contractor's electrical license and insurance matters more here than on almost any other home project.
Frequently asked questions
How long does a panel upgrade take?
Most upgrades take one full day, though the power may need to be shut off for several hours during the swap. Full service upgrades involving the utility meter can take longer to schedule.
Do I need a permit for a panel upgrade?
Yes, in virtually all jurisdictions. It's a safety-critical job that requires inspection — skip a contractor who suggests avoiding the permit.
Will a panel upgrade lower my insurance costs?
Replacing an old fuse box or a panel brand associated with known safety issues (certain now-recalled panel brands from past decades) can sometimes improve insurability or lower premiums — worth mentioning to your insurer after the upgrade.
How do I know what amperage I actually need?
A licensed electrician calculates this based on your home's size, major appliances, and any planned additions like EV charging or a heat pump — not a generic rule of thumb. 200A covers most modern homes; larger homes or heavy electrification plans may need 300–400A.
Can I stay in my home during a panel upgrade?
Yes, for most upgrades — the main disruption is a several-hour power outage during the work, not an extended displacement. Plan around medical equipment, refrigeration, or work-from-home needs for that day.
What's the difference between a panel upgrade and a full service upgrade?
A panel upgrade replaces the breaker box itself. A full service upgrade also replaces the service line, meter base, and the utility connection feeding the panel — necessary when the incoming service capacity, not just the panel, is the limiting factor. It costs more and requires closer utility coordination.
