Top Electrical Companies in Illinois (2026)
Electrical companies across Illinois, from Chicago to Springfield, ranked by real homeowner reviews. Ranked by verified reviews, license checks and responsiveness.
Illinois has no statewide electrician license. Licensing is handled by cities and villages, so the rules change from one town to the next. In Chicago, the Department of Buildings licenses electrical contractors, and every licensed contractor must employ a licensed supervising electrician. Many suburbs register contractors and require a permit for electrical work, and there is no single statewide electrical code: each community adopts its own edition of the National Electrical Code. Before you hire, ask which local license the company holds and who will pull the permit. Severe spring and summer storms and heavy winter snow in the north also make surge protection and standby power worth a conversation.Our ranking brings together local companies across the state and orders them by what homeowners say in their reviews, so you can compare real experiences before you call.

Guides for Illinois
All Illinois guidesQuestions from Illinois homeowners
Does Illinois have a state electrician license?
No. Illinois does not issue a statewide electrician or electrical contractor license. The Illinois Municipal Code lets each city or village set its own licensing or registration rules, so requirements depend on where your home is.
How do I check an electrician's license in Chicago?
The City of Chicago Department of Buildings publishes a lookup of licensed electrical contractors, with license numbers and expiration dates. A Chicago electrical contractor license is issued only to a business that employs at least one licensed supervising electrician, and it must be renewed every year.
Does a Chicago electrician need a license even for small jobs?
Yes. Under the Municipal Code of Chicago (Chapter 4-290), a contractor license is needed to install, alter or maintain wiring regulated by the Chicago Electrical Code, whether or not the job needs a permit. The work must be done by the licensed business and its employees under a licensed supervising electrician.
Which electrical code applies to my home?
There is no single statewide electrical code in Illinois; counties and municipalities adopt their own edition of the National Electrical Code, often with local changes. Chicago uses its own Chicago Electrical Code (Title 14E of the Municipal Code), which is built on the National Electrical Code.
Do I need a permit for electrical work in the suburbs?
It depends on the town, so check with your local building department first. In Naperville, for example, the city states that all electrical work requires a permit, and electrical contractors must register with the city.
What changed for electricians working in Naperville?
Naperville stopped renewing locally issued electrical licenses at the end of 2022. The city now accepts a current International Code Council certification or a license earned by testing in a participating municipality such as Chicago, Elgin or Libertyville.
Is storm protection worth adding to my electrical system in Illinois?
NOAA notes that severe thunderstorms are common in late spring and early summer and can produce tornadoes, and northern Illinois can see major winter snowstorms. Whole-home surge protection and a properly installed standby generator with a transfer switch are common upgrades; both usually need a local permit.
