STATE LICENSE
RequiredConnecticut Department of Consumer Protec…
Electrical work is licensed under CGS chapter 393 by DCP with the Electrical Work Board. Journeypersons qualify through a registered apprenticeship — DCP lists 8,000 on-the-job hours and 576 hours of related instruction for the E-2 — and pass the state exam; a contractor license requires two years as a licensed journeyperson (§ 20-334a). Limited licenses cover narrower scopes such as low-voltage, solar PV, and telephone interconnect.
Licenses expire every September 30. The initial license fee is $150 for a contractor and $120 for a journeyperson (§ 20-335), and the nonrefundable application fees are $150 and $90. Electricians must complete four hours of continuing education each year. Licensed contractors must show their license number on vehicles, ads, bids, contracts, and invoices.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Licensing is exclusively state (DCP). Towns and cities issue electrical permits and inspect; a licensed contractor must sign the permit application (CGS § 20-338b), and work may not start before the permit issues (§ 20-338c). Half of a civil penalty goes to the town whose building official reported the violation (§ 20-341(a)(5)).
The local offices section below names the exact permit desk for every Connecticut county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
DCP states Connecticut has no reciprocal licensing agreements with any other jurisdiction; out-of-state electricians apply through an equivalency path.
DCP licenses individuals, not companies — the business operates under a licensed E-1 holder.
Failing to show the state license number on vehicles, ads, bids, contracts, invoices, and stationery can draw up to $500 per violation after a first warning (§ 20-334(b)).

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Wilfully performing, advertising, or employing others for licensed trade work without the license is a crime once DCP determines in writing that the work requires a license.
The examining board or the DCP commissioner may fine each violation after a hearing; half goes to the town when its building official reported it.
Since P.A. 25-111, DCP may issue a notice of violation after an inspection and then a stop-work order; ignoring it draws a daily fine.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.

Pending verification: Exam vendor and exam fee for ch. 393 trade exams (DCP says separate fees are due to the exam vendor at registration but does not state them) · The exact experience and hours DCP regulation requires for E-1 applicants qualifying by 'equivalent experience and training' rather than two years as a licensed journeyperson · Whether any 2026 regular-session public act changed these fees, thresholds, or insurance minimums — the newest statutory text retrieved is the 2026 Supplement, which reflects only the 2025 session
