Requirements, license levels, and the issuing authority, sourced from Connecticut's official board.
Two things save time in Connecticut. Read the scope-of-work page first, because a limited classification may cover the work you actually do at a lower requirement than the P-2. And register the apprenticeship with the Department of Labor, not DCP, that split trips up applicants who deal only with the licensing agency.
| Requirements | CONNECTICUT USES LETTER-AND-NUMBER LICENCE CODES, and for plumbing the journeyperson license is the P-2. P-2 PLUMBING JOURNEYPERSON. Proof of 576 CLASSROOM HOURS AND 8,000 HOURS OF ON-THE-JOB TRAINING. Both are required, the classroom component is not optional and not substitutable with additional field time. THE APPRENTICESHIP RUNS THROUGH A DIFFERENT AGENCY. Connecticut registers apprentices through the DEPARTMENT OF LABOR's apprenticeship division, which publishes the standards and work schedules, while the LICENCE is issued by the Department of Consumer Protection. Two agencies, one pathway, register with DOL, license with DCP. DCP publishes a 'Plumbing Licenses and Scope of Work' page setting out what each letter code permits, which is worth reading before choosing which license to pursue: the limited classifications exist for narrower work and carry lighter requirements. |
| Reciprocity | DCP publishes a specific application path titled 'Plumbing Journeyperson, Equivalent Out of State License', which is a defined route for applicants already licensed elsewhere, alongside an 'Equivalent Experience and Training' path for those qualifying on experience. Use the correct path: they have different evidence requirements. |
| Renewal | Licenses renew with the Department of Consumer Protection on its published cycle. DCP maintains a plumber continuing education requirement and publishes approved courses on its continuing education pages. |
