Enter a credential number such as HIC.0631057 or ELC.0212758-E1, or a business name.
Every home improvement registration expires on the same day
Connecticut home improvement contractor registrations run for a year and all expire on March 31. That turns one date into a cliff: every remodeler, roofer and siding sub on your roster has to renew at once, and the ones who don't are unregistered on April 1 — usually mid-job, at the start of the building season.
TrackMyVendor re-checks each sub's registration against DCP's data daily, and shows which ones have not renewed before the date arrives. Set it up free →
Registrations and trade licenses: two different things
The Department of Consumer Protection (DCP) issues both, and they answer different questions. A registration says a business may contract for a kind of work — it is not a test of skill. A trade license says a person or firm passed the exams to do electrical, plumbing or mechanical work.
Registrations
- Home Improvement Contractor (HIC) — remodeling, repair and improvement work contracted with a homeowner. Expires March 31 every year.
- New Home Construction Contractor (NHC) — building new homes; separate from HIC, which excludes new construction.
- Major Contractor — general contractors and construction managers on larger commercial projects.
- Demolition Contractor — demolition work.
Trade licenses
- Electrical
- Plumbing & piping
- Heating, piping & cooling
- Sheet metal
- Fire protection sprinkler
- Elevator
Each at contractor and journeyperson level, unlimited or limited in scope.
A sub can need both
An electrical contractor doing a kitchen remodel for a homeowner needs the trade license for the wiring and, typically, an HIC registration to contract the job. A journeyperson's license lets that person do the work but not contract it — the contractor license has to sit with the firm. Check the credential that matches the contract, not just the one the sub mentions first.
Reading a Connecticut credential number
| Number | What it is |
|---|---|
| HIC.0631057 | Home improvement contractor registration |
| ELC.0212758-E1 | Electrical license; the suffix is the license's category, here an unlimited electrical contractor |
| PLM.0212758-P1 | Plumbing & piping license, unlimited contractor |
Typed without the dot or the leading zeros — "HIC 631057", "elc 212758 e1" — the lookup above still finds it.
What a Connecticut lookup result means
Unlike states that publish only current licensees, DCP's data keeps lapsed credentials too — so a Connecticut lookup can tell you a registration existed and lapsed, not only that it wasn't found. For the general picture, see the contractor license status guide.
Current, with the expiration date ahead.
For an HIC registration, the date will be March 31. If your project runs past it, put the renewal on your calendar now.
Lapsed and not renewed.
The business or person held the credential and did not renew it. Before they work for you, ask for the renewed registration or license — and look it up again rather than accepting a screenshot.
DCP has restricted the credential.
The holder cannot work under it. Check DCP's own records for the reason before deciding anything about the sub.
Property manager note: the HIC registration is about work for homeowners. A vendor maintaining a commercial or apartment property for you may not need one — but any electrical, plumbing or HVAC work still needs the trade license. Check the trade credential for the work, whatever the property type.
Track Connecticut credentials automatically
What TrackMyVendor re-checks against DCP's data on its own, and what it tracks by the expiration date you record.
HIC, new home and major contractor registrations, and electrical, plumbing, heating & cooling, sheet metal, fire protection and elevator licenses. A registration that lapses or is suspended changes on the sub's record.
Local permits, certifications and anything else a sub holds can be added with its expiration date and gets the same reminders.
Every plan gets the Monday summary of anything expiring; per-deadline alerts at 90, 60, 30 and 7 days are on Starter and above.

A registration is not insurance
Registering as a home improvement contractor in Connecticut does not prove the business carries liability insurance or workers' comp. Those come from the certificate of insurance, which changes every policy year and is where most GCs' chasing actually happens.
Certificates collected for you
Subs upload their COI from a link — no login, from a phone — and AI COI parsing reads the carrier, limits and dates.
W-9s in the same request
The same link collects the W-9, and the name and TIN are read automatically.
