How much does a 100-amp to 200-amp panel upgrade cost in Chicago?

Most 100A-to-200A upgrades in Chicago run $2,800-$4,500 when the existing service entrance is in good condition and the new panel is going in the same location. Upgrades that require relocating the meter, replacing the weatherhead and service riser, upgrading to a combo meter main, or adding a sub-panel push the total to $5,500-$8,500.

Do I need a permit to upgrade my Chicago panel?

Yes, always. Chicago requires an electrical permit, a licensed electrical contractor on the permit, and both rough and final inspections. ComEd will not reconnect the service after an upgrade without a sign-off from the Department of Buildings. We handle all permit and ComEd coordination.

How long does a Chicago panel upgrade take?

Most straightforward 200A upgrades complete in 1-2 days on site. Power is off for 4-8 hours during the panel swap. Permit approval typically takes 1-2 weeks before the work date, and ComEd coordination for the service drop adds a few days to the schedule.

Will ComEd charge me to upgrade my service?

ComEd typically charges nothing for a standard service upgrade at the existing location. If the service needs to move to a new meter location, ComEd may charge for service re-routing. We coordinate with ComEd on your behalf and let you know about any utility-side charges before work begins.

Does a panel upgrade require me to rewire the house?

No. A panel upgrade replaces the service equipment and breakers but keeps existing branch-circuit wiring in place. If your home has knob-and-tube or aluminum wiring, however, we'll often recommend [home rewiring](/services/chicago/home-rewiring-chicago) as a companion project since the panel upgrade alone doesn't address the legacy wiring safety issues.

An electrical panel (breaker box) is the nerve center of your home's electrical system. As your household demands more power—new HVAC systems, EV chargers, updated kitchen appliances—your existing panel may no longer handle the load. A panel upgrade becomes necessary to:

Safely support additional circuits
Meet modern code standards
Prevent frequent breaker trips
Enable future electrical additions

Typical Chicago homes range from 100-amp to 200-amp service. Most modern homes need 200 amps; older homes often have only 100 amps.

Panel Upgrade Cost Range in Chicago

Service	Cost Range
100 → 150 Amp Upgrade	$1,500 – $2,500
100 → 200 Amp Upgrade	$2,000 – $3,500
150 → 200 Amp Upgrade	$1,800 – $3,000
200 → 300 Amp Upgrade	$3,000 – $4,500+
Main Panel Replacement Only	$1,200 – $2,000

These are estimates for Chicagoland residential work.

What Affects Your Actual Cost

1. Utility Company Involvement

Your electric utility company (Commonwealth Edison) must upgrade service lines and the meter base. This can add $500–$2,000 to your total project cost and may take 2–4 weeks to coordinate.

2. Electrical Code Requirements

Chicago follows the National Electrical Code (NEC) and city amendments. A licensed electrician must:

Secure a permit from Chicago Department of Buildings
Ensure new panel meets current code (grounding, bonding, labeling)
Coordinate utility inspection

3. Panel Location & Access

Easy access (finished basement wall, garage): standard pricing
Difficult access (deep basement corner, buried under drywall): additional labor ($500–$1,500)
Outdoor installation: weatherproofing adds $300–$800

4. Existing Wiring Condition

If your home has outdated wiring (knob-and-tube, aluminum) or corroded connections, electricians may recommend additional repairs, increasing total project cost.

5. Sub-panel vs. Main Panel

Main panel upgrade: higher cost due to utility coordination
Adding a sub-panel: $800–$1,500 (useful for additions without upgrading main service)

What's Included in a Panel Upgrade

A complete panel upgrade with E&P Electric includes:

✓ Permit acquisition and filing
✓ Utility coordination (ComEd)
✓ Labor to remove old panel
✓ Installation of new panel
✓ Transfer of existing breakers (or replacement)
✓ Code inspection
✓ Final city inspection sign-off
✓ Electrical testing & certification

Why Prices Vary: The Chicago Factor

ComEd Coordination Delays

Chicago's utility company can add 2–6 weeks to your timeline, and rushing coordination may add rush fees.

Historic Building Codes

Older Chicago homes were built to older codes. Upgrades may require bringing other systems into compliance (grounding, bonding, GFCI requirements).

Labor Costs

Chicago's licensed electricians must hold an Electrical Contractor's License. Supervising Electricians (required for major work) command higher rates due to expertise and licensing.

Permit Complexity

Chicago's Department of Buildings reviews panel upgrades carefully. Complex jobs may require additional inspections.

When Should You Upgrade Your Panel?

Signs you need an upgrade:

Constant breaker trips when running multiple appliances
Adding a major load (EV charger, heat pump, new kitchen)
Home is older than 40 years with original 100-amp service
Planning a significant renovation
Insurance company recommends it
Code violations found during inspection

Don't wait if: you smell burning near the panel, see scorch marks, or hear buzzing sounds. Call immediately—this is a fire hazard.
