If your home still runs on a 100-amp panel — or a panel from a manufacturer with a known failure history — you’ve probably wondered what an upgrade actually costs. The honest answer: it depends on what your home needs, and any electrician who quotes you a single number sight-unseen is guessing. Here’s how the ranges break down in Northern Virginia in 2026, and what moves a project from the low end to the high end.
Quick answer: typical 2026 ranges
| Project | Typical Northern Virginia range |
|---|---|
| Panel replacement, same amperage (condos & smaller panels) | $1,800 – $3,000 |
| 200-amp panel upgrade | $4,000 – $6,000 depending on factors like underground vs. overhead service |
| 100A → 200A “heavy-up” incl. new service entrance | $4,500 – $8,500 |
| Add-ons: new dedicated circuits | $500 – $1,500 each, depending on distance from the panel |
| County permit + inspection | $300 – $450 depending on jurisdiction |
Every figure above is a range on purpose. Two houses on the same street can land thousands apart based on the factors below.
What actually drives the price
Your existing service. A true heavy-up (100A → 200A) usually means a new meter base, new service entrance cable, and utility coordination with Dominion — that’s why it costs two to three times a like-for-like panel swap.
The panel you have now. Federal Pacific and Zinsco panels are replaced, not repaired — and if the panel shows heat damage or corrosion, adjacent components often need attention too. See our guide to panel replacement.
Code-required upgrades. When the panel is opened up, current code (as adopted in Virginia) can require AFCI/GFCI protection, grounding updates, and surge protection. These aren’t upsells — they’re what passes inspection.
Access and location. Finished basements, cramped closets, or exterior relocations add labor.
What you’re planning next. An EV charger, hot tub, heat pump, or workshop changes the load calculation — sometimes a 200A upgrade is the prerequisite, sometimes a load-managed solution avoids it. A proper load calculation tells you which, before you spend.
Permits and inspections by county
A panel upgrade requires an electrical permit and inspection everywhere in Northern Virginia — no exceptions, and you should walk away from any contractor who suggests skipping it. In practice, budget $300–$450 for the permit and inspection on a panel project in 2026, varying by jurisdiction (Fairfax, Arlington, Loudoun, Prince William, Stafford, Fauquier) and project scope — posted fee schedules change, so verify current numbers on your county’s permitting portal.
A reputable quote itemizes the permit. SparkWise pulls the permit, schedules the inspection, and coordinates the utility cut-over as part of every panel job — your project isn’t done until it passes.
Why quotes differ so much (and red flags)
Get two or three quotes and you’ll likely see a spread. Legitimate reasons: different assumptions about the service entrance, code items included vs. excluded, and warranty terms. Red flags: no permit in the quote, no load calculation, a price given without seeing the panel, or a contractor who can’t show a Virginia license.
When an upgrade is worth it
Breakers that trip regularly, a panel that’s warm to the touch, flickering when large appliances start, an FPE/Zinsco label, or plans for an EV or major addition — any of these justifies at least an evaluation. Beyond safety, a 200A service is increasingly a resale expectation in this market.

Frequently asked questions
How much does it cost to upgrade from 100 amp to 200 amp in Northern Virginia?
Most full heavy-ups run $4,500–$8,500 in 2026, including the panel, service entrance work, permit, and inspection. A straightforward 200-amp panel upgrade runs $4,000–$6,000 depending on factors like underground vs. overhead service, and a like-for-like replacement (common in condos and homes with smaller panels) is typically $1,800–$3,000.
Do I need a permit to replace my electrical panel in Virginia?
Yes — every Northern Virginia jurisdiction requires an electrical permit and inspection for panel work. Expect roughly $300–$450 for permit and inspection depending on the county.
How long does a panel upgrade take?
Most residential upgrades are completed in one day, with a scheduled power interruption. Utility coordination for a service upgrade can add lead time before the install date.
Will my homeowner’s insurance care about my panel?
Increasingly, yes. Some insurers surcharge or decline homes with Federal Pacific or Zinsco panels; replacing one can matter at renewal or sale.
Is a 200-amp panel enough for an EV charger?
Usually, yes — but it depends on your home’s total load. A load calculation determines whether your panel can take a Level 2 charger circuit as-is, needs load management, or needs an upgrade first.
