State ladder: apprentice → journeyman → master Primary sources Checked October 22, 2026
| The ladder | Connecticut |
|---|---|
| Journeyman credential | P-2 Unlimited Journeyperson Plumber |
| Total hours required | 8,000 |
| Classroom hours | 576 |
| Apprentice registration | Required — hours count only while registered |
| Exam | State examination vendor (DCP: separate fees are due to the exam vendor at exam registration) — DCP does not publish the vendor's exam fee on the licensing pages reviewed; the DCP application fee for a journeyperson license is $90 — the fee is not returned by the Department. License fee field below is that DCP application fee. |
| License fee | $90 |
| Renewal | Every 1 year — all plumbing and pipefitting licenses expire annually on October 31 |
| Continuing education | 5 credit hours every two years (unlimited journeyperson), per DCP Plumber Continuing Education page |
| Master credential | P-1 Unlimited Plumbing Contractor (Connecticut has no 'master plumber' title) |
Registration, in the board’s terms: The standard route is completion of a registered apprenticeship program (Connecticut Department of Labor Apprenticeship Division). DCP requires proof of BOTH the on-the-job hours and the classroom hours; classroom hours must match the Exhibit A curriculum, and work experience will not be accepted in lieu of the classroom requirement (DCP, Equivalent Experience and Training).
P-1 Unlimited Plumbing Contractor (Connecticut has no 'master plumber' title): Two years as an unlimited licensed journeyperson (P-2) or equivalent experience and training, and passage of the P-1 contractor examination (DCP, Plumbing Licenses and Scope of Work). For the equivalent out-of-state contractor route, DCP's chart requires 12,000 OJT hours (8,000 plus two years / 4,000) and 576 classroom hours.
DCP application fee for a contractor license is $150 — the fee is not returned by the Department; contractor renewal fee is $150 (journeyperson renewal $120). Only individuals can apply — company applications are not accepted (DCP licensing page).
All plumbing and pipefitting licenses expire annually on October 31 (renewal: contractor $150, journeyperson $120). DCP publishes reapplication information for lapsed licenses, but no fixed reinstatement window in months was stated on the DCP pages reviewed on 2026-10-22.
Reinstatement: Reapplication information is published by DCP; the exact post-expiry reinstatement period was not stated on the primary pages reviewed in this pass.
Past the line: Not stated on the primary pages reviewed in this pass.
Connecticut endorses journeyman licenses from: none. DCP states verbatim: 'Connecticut does not have reciprocal agreements with any other jurisdiction.' An out-of-state licensee may still apply through the equivalent out-of-state license route, which requires proof the home license required the same classroom hours, curriculum, and OJT hours as the Connecticut license sought — a case-by-case equivalency review, not reciprocity.

Included in the $49 PlumberLicenseCheck Kit
One payment. Yours to keep. The checkers above stay free either way.
The seat: P-1 Unlimited Plumbing Contractor (individual licensee). A P-2 journeyperson may do plumbing and piping work only while in the employ of a contractor licensed for such work (DCP scope of work). Contractor licenses are issued only to individuals — DCP does not accept company applications — so a plumbing business operates through an individually licensed P-1 contractor who has held the P-2 for more than two years.
Statewide DCP licensing; no separate city/county journeyman system replaces the P-2/P-1 ladder.
