Electrical panel upgrade cost: 2026 price guide
Most homeowners pay $1,500 to $4,000 to upgrade from a 100-amp to a 200-amp panel. Older homes with 60-amp fuse boxes, or properties needing a full utility service upgrade, run higher.
Electrical panel upgrade cost varies more than almost any other home system, because the panel itself is often the cheapest part of the job. What actually drives the price of upgrading an electrical panel — whether you’re going from 100 amp to 200 amp, replacing an old fuse box, or adding capacity for an EV charger and heat pump — is the condition of your home’s existing wiring, whether the utility company needs to upgrade the service line feeding your house, and local permitting requirements.
This guide breaks down electrical panel replacement cost by amperage and scope, what a licensed electrician’s invoice typically includes, and the signs that mean your panel needs attention now rather than “eventually.”
By scope
Cost by upgrade type
Most homes upgrade to 200 amps. Larger or fully electrified homes sometimes go to 400.
| Upgrade type | Typical scope | Estimated cost |
|---|---|---|
| 100-amp panel replacement | Same amperage, new panel only | $850–$1,600 |
| 100 → 200-amp upgrade | New panel, breakers, possible wire updates | $1,500–$4,000 |
| 200 → 400-amp upgrade | Larger homes, EV + heat pump + solar loads | $2,000–$6,000+ |
| Subpanel addition | More breaker slots, same total capacity | $500–$1,500 |
| Pre-1960s homes, mandatory rewiring | $3,000–$8,000+ |
Why old fuse boxes cost more to fix than upgrade
Homes built before 1960 with 60-amp fuse-based service weren’t wired for today’s electrical load — central air, EV chargers, and multiple large appliances running at once. Beyond capacity, aging fuse boxes and the knob-and-tube or early Romex wiring often paired with them are associated with a higher risk of overheating and electrical fires, which is why most insurers and local codes require a full rewiring rather than a like-for-like fuse box swap.
What to do: get an electrician to inspect the panel and wiring together, not just quote the panel. If your insurer has flagged the panel (Federal Pacific and Zinsco brands are common red flags), treat the upgrade as a priority rather than a someday project.
What’s on the invoice
What a fair electrician’s quote includes
A panel upgrade is licensed, permitted electrical work — not just swapping a box. Here’s what should be itemized.
- New panel + breakers ($100–$500 in parts)
- Labor: $40–$100/hr, typically 8–10 hours total
- Permit & inspection fees
- Whole-house surge protector (code requirement in many areas)
- Utility coordination, if the service line needs upgrading too
Common trigger
Upgrading for an EV charger or heat pump
A Level 2 EV charger needs a dedicated 40–50 amp circuit — a significant load on a 100-amp panel already near capacity. Many electricians bundle a panel upgrade with the EV circuit install, often saving $200–$500 versus doing them separately.
Even without an EV today, pre-wiring or running conduit during a panel upgrade adds only $100–$300 and avoids opening walls again later.
Don’t ignore these
Signs your panel needs an upgrade
Breakers trip repeatedly
Especially when running the microwave, AC, and another appliance at once — a sign the panel can’t handle current demand.
Lights flicker or dim
Especially when a large appliance kicks on — suggests the circuit or panel is undersized for the load.
You still have a fuse box
Fuse boxes are largely obsolete; most insurers and buyers’ inspectors flag them immediately.
No room for new circuits
Adding a hot tub, EV charger, or finished basement circuit and finding zero open breaker slots.
Common questions
Frequently asked questions
A standard panel-only swap takes 8–10 hours in a single day. If the utility needs to upgrade the service line or meter, expect an additional visit and possibly a short power outage scheduled with your utility company.
Yes, almost universally. Panel work is inspected for safety code compliance, and skipping the permit can void your homeowners insurance and complicate a future home sale.
Yes, typically for several hours during the swap itself. If the utility needs to disconnect and reconnect service at the meter, that’s coordinated separately and is usually brief.
For a smaller home without an EV, heat pump, or large electric range, 100 amps can still be adequate. For anything over roughly 1,800 sq ft, or homes adding electric vehicle charging, 200 amps is the modern standard.
If your problem is running out of breaker slots but your total power is fine, a subpanel ($500–$1,500) solves it. If breakers trip from overall demand, that’s a capacity problem — a subpanel won’t fix it, and you need a full service upgrade. A licensed electrician’s load calculation tells you which situation you’re in.
Generally no — a proactive upgrade is an out-of-pocket home improvement. However, some insurers offer a premium discount once an outdated or flagged panel (like Federal Pacific or Zinsco) is replaced.
In nearly every jurisdiction, no. Panel work involves the main electrical service and requires a licensed electrician and permitted inspection; DIY panel work is both illegal in most areas and genuinely dangerous.
A panel-only replacement swaps the box using your existing service line and meter. A full service upgrade also replaces the mast, meter base, and coordinates with the utility to increase the amperage delivered to your home — required when jumping to significantly higher amperage or when the existing line can’t support the new panel.
