Electrical Panel Upgrade Cost (2026): 100A vs 200A vs 400A Pricing
By Fabio Freire, Founder & General Contractor at EZ-Estimates. Published 2026-05-01.
Electrical Panel Upgrade Cost (2026)
A panel upgrade is one of the most quoted electrical jobs because:
- Homeowners with 100A service want 200A for EV chargers, heat pumps, and solar
- Aging Federal Pacific and Zinsco panels need replacement for safety
- Solar installs and EV chargers often require panel upgrades to add capacity
Here are the 2026 numbers.
How Panel Upgrades Are Priced
Panel upgrades are priced as a complete service:
- Removal of existing panel
- New panel + breakers
- Service entrance cable (SEC) upgrade if needed
- Meter base replacement (often required by utility)
- Grounding system update
- Permits + utility coordination
- Inspection
Typical 2026 pricing:
- 100A panel upgrade (panel only, no service change): $1,500-3,500
- 100A to 200A upgrade (full service upgrade): $2,500-5,500
- 200A new panel install (replacement): $1,800-4,000
- 400A panel + service upgrade: $4,500-9,500
- Sub-panel install (adding 100A or 200A sub): $1,000-3,000
- Federal Pacific or Zinsco panel replacement (safety swap): $2,500-5,500
These are 2026 ranges for residential. Add 30-50% for commercial work.
What Drives Price Variation
1. Service entrance cable (SEC) upgrade
If upgrading from 100A to 200A, the service cable from the meter to the panel often needs upgrading. SEC for 200A is #4/0 aluminum or #2/0 copper. Material: $200-500. Labor for replacement: $300-800.
2. Meter base replacement
Many utilities require meter base replacement during a service upgrade. Material: $150-350. Labor: $200-500. Often utility company swaps the meter at no charge during your appointment.
3. Mast and weatherhead
If overhead service, the mast (pipe through the roof) and weatherhead may need replacement. Material: $150-400. Labor: $400-1,000. Roofing sealant included.
4. Grounding system update
Code requires updated grounding (usually 2 ground rods 6 ft apart bonded to panel, plus a water pipe bond). Material: $50-150. Labor: $200-500.
5. Permit and inspection
Most jurisdictions require permits for panel work. Permit: $50-300. Inspection: included in permit fee or separate ($75-200).
6. Utility coordination
The power company has to disconnect the service for the work. They may require a re-energize after inspection. This usually involves 4-8 hours of downtime, not days. Some utilities charge $100-500 for the disconnect/reconnect.
Material Costs (2026)
Panels (residential):
- 100A panel + breakers: $200-450
- 200A panel + breakers: $300-700
- 400A panel + breakers: $700-1,500
- Smart/connected panel (Span, Schneider Wiser): $3,500-6,500
Wire and cable:
- #2/0 SEC copper (per foot): $4-7
- #4/0 SEC aluminum (per foot): $1.50-3
- Conduit (if running underground): $1-4/lin ft
- Romex and miscellaneous: $200-500 per panel job
Breakers (replacement during install):
- 15A or 20A standard: $5-10 each
- AFCI/GFCI breakers (required by code in many circuits): $25-50 each
- Tandem breakers: $15-30 each
Other materials:
- Meter base: $150-350
- Weatherhead + mast (overhead service): $100-300
- Ground rods: $20-30 each
- Bonding wire: $30-80
Labor Costs
Panel-only swap (existing 200A panel replaced with new 200A panel):
- 4-8 hours of work for a 2-electrician crew
- Crew rate: $100-200/hour burdened
- Labor cost: $400-1,600
Full service upgrade (100A to 200A):
- 8-16 hours of work
- Includes SEC, meter base, possibly mast
- Labor cost: $800-3,200
Crew rates:
- Lead electrician (master): $50-90/hour wage
- Journeyman: $35-60/hour wage
- Apprentice: $20-35/hour wage
What Drives Buyers To Upgrade
Common reasons homeowners upgrade panels:
- Buying an EV — most homeowners with 100A service do not have capacity for a Level 2 charger
- Installing solar — most utilities require a 200A panel for solar interconnect
- Adding heat pumps or electric appliances — load calculations require capacity
- Selling the home — Federal Pacific and Zinsco panels are flagged in inspections
- Adding a hot tub or pool — additional 50-60A circuit needed
- Building an addition — extending circuits requires available capacity

Common Mistakes That Kill Margin
1. Forgetting the AFCI/GFCI requirement. Code (NEC) requires AFCI or GFCI breakers on most residential circuits during a panel swap. 6-12 of these breakers at $25-50 each = $150-600. Forgotten = eaten.
2. Underbidding the SEC upgrade. Quoting "panel swap" without SEC upgrade is misleading on a 100A-to-200A job. Always confirm if the SEC is sufficient for the new amperage.
3. Ignoring the grounding update. New panel = new grounding code. 2 ground rods + water pipe bond is required.
4. Not coordinating with the utility. Showing up to the job without arranging the disconnect = wasted day.
5. Free smart panel swap. Customer asks "can we make it a Span panel instead?" Smart panels are 5-10x the cost of standard. Issue a change order, do not absorb.
Markup and Margin
Standard markup on residential electrical: 30-50%. Higher than other trades because licensing requirements limit competition.
Solo electricians run 25-35%. Established electrical companies need 40-50%. See Markup calculator.
