How to verify electrical contractor licenses in Connecticut

Check any Connecticut electrical contractor license — status, expiration, and disciplinary history — through one normalized API, or look it up by hand on the state board portal.

What you can verify

Trade: Electrical Contractor

Data source: Connecticut open data portal (daily)

Coverage: Home Improvement, New Home Construction, Electrical, Plumbing, HVAC, Fire Protection

Connecticut also supports name search — when you only have a contractor's name, the /search endpoint returns every matching license with full metadata, electrical contractor licenses included.

Looking for a different Connecticut trade, or the same trade in another state? See the full Connecticut license guide or the national Electrical Contractor lookup by state.

One call. The whole picture.

The /verify response is identical in shape across every state and trade, so your integration code never changes per jurisdiction:

{
  "valid": true,
  "name": "SAMPLE CONTRACTING LLC",
  "license_number": "SAMPLE-12345",
  "trade": "electrical",
  "expiration": "05/12/2027",
  "status": "Active",
  "state": "CT",
  "disciplinary_actions": [],
  "source_url": "https://elicense.ct.gov/Lookup/LicenseLookup.aspx",
  "cached": false,
  "checked_at": "2026-07-29T15:00:00Z"
}
