A Illinois home averages 693 kWh a month, about 1.0 kW of continuous draw, so the big new loads (an EV charger, a heat pump, an induction range) are what push a panel past its limit, not everyday use; a load calculation tells you whether you need a service upgrade or just a few breaker spaces.

How to choose an electrician in Illinois

Verify the license and insurance

Electrical work in Illinois must be done or supervised by a licensed electrical contractor, and the license should be in the name of the company quoting you, not a friend of the crew. Look it up on the licensing board linked below, ask for proof of liability insurance, and confirm the contractor, not you, pulls the permit and schedules the inspection.

Start with a load calculation, not a panel size

For a panel upgrade, a new 240V circuit, or any electrification project, a good electrician runs the NEC Article 220 load calculation on your home before quoting. It decides whether you need a 200 A service upgrade (which involves the utility and the meter), a panel replacement at the same service size, a subpanel, or a load-management device that avoids the upgrade entirely. A quote that jumps straight to "200 amp upgrade" without the math is a guess.

Compare written quotes on the same scope

Get at least three quotes that name the panel brand and ampacity, the number of spaces, breaker types required by code (AFCI, GFCI), the wire gauge and run length for new circuits, whole-house surge protection, drywall repair, the permit and inspection fees, and the utility coordination. Ask what happens if the inspector flags existing issues, such as aluminum wiring or a missing ground, and whether those fixes are priced in.

What to know before hiring in Illinois

The largest utilities serving Illinois homes are Commonwealth Edison (2,922,223 residential customers, 15.2¢/kWh), Ameren Illinois (520,498 residential customers, 15.3¢/kWh) and MidAmerican Energy (73,564 residential customers, 10.0¢/kWh). Your utility sets the rate your new circuits draw from, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.

Check the license before you sign

Illinois licenses electrical contractors at the city or county level rather than statewide; the City of Chicago Department of Buildings, Trade Licensing is the starting point. Illinois has no statewide electrician license; Chicago licenses Supervising Electricians and Electrical Contractors, and other cities and counties run their own programs.

Frequently asked questions

Verify the electrical contractor license on the Illinois licensing board, confirm liability insurance, and make sure the contractor pulls the permit and schedules the inspection. For a panel or service upgrade, insist on an NEC 220 load calculation before the quote. Get at least three written quotes on the same scope (panel size, circuits, breaker types, surge protection, patching) and compare what each one includes.
