  1. electrical license in Illinois: do you need one?

    Electrical work is licensed in essentially every state, with required apprenticeship hours and a licensing exam. Permits and inspections apply to most jobs. In Illinois, the state board or agency that handles electrical licensing is linked below — check it, and your city or county business-license office, before you advertise or take a job. If Illinois doesn't license electrical work at the state level, a local business license (and often liability insurance) is still expected.

  5. What to charge for electrical in Illinois

    Service call $100–$200, small jobs flat-rate ($150–$800), panel upgrades $1,800–$4,500, EV charger installs $600–$2,200, whole-home rewires bid per square foot. GC work is bid off plans. Check what the established electrical businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.

  6. Getting your first electrical customers in Illinois

    General contractors, Google Business Profile, and realtor/home-inspector referrals. Panel upgrades, EV chargers, and generator installs are high-value. Build relationships with general contractors for steady work. Consistent base demand plus growth drivers — EV chargers, panel upgrades for heat pumps and solar, generator installs after outages. Permit and inspection turnaround is often your real bottleneck, not leads.

  7. The mistake most first-year electrical owners make

    Not building general-contractor relationships. Consumer service work is competitive and price-shopped; a steady GC feeding you rough-in work on their builds is worth more than any ad spend.
