Connecticut plumber license requirements
The short answer
As of July 2026, Connecticut licenses all plumbing work statewide through the Department of Consumer Protection (Plumbing and Piping Work Examining Board), using a contractor/journeyperson structure rather than journeyman/master tiers. The core credentials are the P-2 Unlimited Journeyperson (8,000 on-the-job hours plus 576 classroom hours via a CT DOL apprenticeship or equivalent) and the P-1 Unlimited Contractor (an additional 2 years/4,000 hours as a licensed journeyperson, 12,000 hours total). Numerous limited licenses (J-1 through J-4, P-6 through P-9, PP, SP series) cover specialty scopes, and all licenses expire annually on October 31.

How much does a Connecticut plumber license cost?
Getting a P-2 Unlimited Journeyperson Plumber license in Connecticut costs $90 in board fees, before any training. That is the application fee charged once, with renewal charged separately below. No board publishes this total, so it is added up here from the schedule it does publish. An exam is required and its fee is not in that figure, because no amount for it appears in the board material this page is built from. Check the board's current fee schedule before budgeting.
- Application fee$90
- Renewal fee (recurring)$120
How often do you renew, and what continuing education is required?
Renewal period: Annual, all plumbing and pipefitting licenses expire October 31 each year
How does the apprenticeship route work?
The standard path is a plumbing apprenticeship registered with the Connecticut Department of Labor; completing it qualifies the apprentice to sit for the P-2 journeyperson exam. Applicants without a CT DOL apprenticeship may qualify under the 'equivalent experience and training' path by documenting 8,000 on-the-job hours AND 576 classroom hours (classroom hours must match required course content; OJT cannot substitute for classroom hours, and CE or manufacturer certificates do not count).
Which states does Connecticut have license reciprocity with?
No published agreement for this trade names Connecticut. That is not the same as a closed door: states without a published list usually take out-of-state applicants through an endorsement or equivalency review instead, decided case by case on the requirements set out above.
