You can’t rush through the training it takes to become a plumber, but that time and effort can lead to a career that is long-lasting, lucrative, and fulfilling. Almost every state requires plumbers to be licensed because it’s complicated work that impacts the health and safety of our society.
According to the U.S. Bureau of Labor Statistics , there are 504,500 plumbers nationwide, and Connecticut employs 4,180 of them. The national number is projected to grow 5% from 2024 to 2034, adding 44,000 plumbers to the ranks across the country. In Connecticut, according to CareerOneStop, the U.S. Department of Labor’s job search website, the projected growth rate is double, at 12% for plumbers, pipefitters, and steamfitters.
Contractors struggle to find skilled tradesmen like plumbers, electricians, and HVACR or mechanical professionals while the demand for them continues to grow. According to the Associated General Contractors of America, “Construction employment in Connecticut in July 2025 totaled 62,800, a decrease of 500 (-0.8%) from July 2024 and an increase of 3,300 or 6% from February 2020.” So, if you get the training you need, you should have a variety of jobs to choose from when you’re ready.

Plumbing License Requirements for Plumbers in Connecticut
Is a license required for plumbers in Connecticut? Yes, and it is mandated from the very beginning.
In the state of Connecticut, you must be licensed to legally perform plumbing work. The state requires an apprenticeship and licenses journeypersons and contractors. The Connecticut Department of Consumer Protection (DCP) based in Hartford issues all professional licenses and oversees the Plumbing and Piping Work Examining Board.
Types of Plumbing Licenses in Connecticut
What are the different types of plumbing licenses in Connecticut?

How Much Does It Cost to Get a Plumbing Contractor License in Connecticut?
Since Connecticut requires all plumbing and piping professionals to begin their career path with a registered apprenticeship, it’s possible to get started with very little expense. Apprenticeships are sometimes referred to as “The Other Four-Year Degree,” because it’s like college for the trades. If you get one of the coveted apprentice openings through your local Joint Apprenticeship Training Committee, it’s like getting a full-ride scholarship to college.
If you begin your plumbing education through the Connecticut Technical Education and Career System, you’ll pay $325 per in-person course, $345 for online course, and a non-refundable registration and technology fee of $50. You may also be able to receive tuition reimbursement under the Apprentice State Expansion (ASE) federal grant awarded to the Connecticut Department of Labor Office of Apprenticeship Training. The details can be found at this link. Other colleges and universities have different rates.
The application fee for any of the journeyperson licenses is $90. The examination costs $59. The journeyperson initial license fee of $120 will be due after successful completion of the exam.
The application fee for any of the contractor licenses is $150. The examinations cost $59 per portion. At the contractor level, you will need to take both the trade and the Business and Law exam, so that will be $118. The contractor initial license fee of $150 will be due after successful completion of the exam.
All plumbing and piping licenses expire on Oct. 31. Renewal fees are $150 for contractors and $120 for journeypersons.
How to Get a Plumbing License in Connecticut
Becoming a plumbing professional in Connecticut requires experience and education, but the exact path one can take varies. All the details of these requirements can be found on the Office of Apprenticeship Training website. They’ve even published “A Career in the Trades” guide and a message to current and prospective apprentices.
APPRENTICESHIP/WORK EXPERIENCE: In Connecticut, you can get a jump on completing a registered apprenticeship program at one of the technical high schools in the state. The Connecticut Technical Education and Career System serves high school students during the school day and adults through its extension program in the evenings. If you accumulate the classroom instruction requirements for testing for your journeyperson license as a high school student, then when you graduate you’ll just need to find a job in the industry to get the paid on-the-job training that’s required to complete a registered apprenticeship. That’s just one option though.
Alternatively, you can enroll in a plumbing program through the Connecticut Technical Education and Career System or another college after graduating from high school to complete your required formal education before accumulating the necessary work experience. Again, you would then need to find a job in the field, and your employer must register you as an apprentice. Make sure you receive a copy of your approved registered apprenticeship agreement from your sponsor (employer). This is your record of registration and lists important information such as your wage progression, trade registration category, and any credit for previous registered experience.
If you’d rather earn while you learn, you can apply for an apprentice position with a local union or trade organization or a sponsoring employer. You will be required to attend classes at night or on weekends to get the requisite theoretical training, but you’ll be getting your academic instruction in tandem with your practical experience, and you probably won’t be paying for all of it. Often your employer or union will pick up some or all of those costs.
At whichever point you begin working for a licensed plumbing contractor, make sure your employer registers you as an apprentice to get your work experience documented. Unregistered work hours will not count toward completion of your apprenticeship program. Also make sure you obtain your apprentice identification card from your sponsor after your registration is approved. You must carry a valid apprentice identification card at all times while on the job and to register for the related instruction. Your apprentice identification card is valid only for the sponsor with whom you are registered and carries an expiration date. If you leave a sponsor and go to work for another sponsor, you must be re-registered. The Office of Apprenticeship Training makes it easy for you to navigate the process and keep track of your hours. The Apprentice Handbook includes all of the pertinent information you’ll need as well as a place to record the hours you’ve worked.
APPLY FOR LICENSE: Once you’ve completed an approved apprenticeship program, you’ll need to apply for whichever of the unlimited or limited license designations in which you’ve acquired your experience. You’ll send your completed license application, $90 journeyperson application fee, and the original copy of the Letter of Apprenticeship Completion Certificate to:
PSI Licensure Certification 3210 East Tropicana Ave. Las Vegas, NV 89121
If everything is in order, you will be issued an Examination Eligibility postcard with instructions for scheduling and paying for the examination.
TAKE LICENSING EXAM: The Department of Consumer Protection has contracted with PSI Exams to administer all of the professional licensing exams. Once you have passed the journeyperson exam, you’ll need to pay your initial license fee of $120 to receive your license.
CONSIDER BECOMING A PLUMBING CONTRACTOR: You may work indefinitely as a licensed journeyperson. If you choose to apply for your contractor's license, you will need to work as a licensed journeyperson for two years and send your completed application, $150 contractor application fee, and any required documents to PSI.
TAKE LICENSING EXAM: For contractor licenses, you must take both the appropriate trade exam and the Connecticut Business and Law examination. Once you have passed both exams, you’ll need to pay your initial contractor license fee of $150 to receive your license.
All licenses must be renewed annually, which can be done through an online portal on the Department of Consumer Protection website.
How Long Does it Take to Get a Plumbing Contractors License in Connecticut?
The length of time it takes to become licensed depends on the type of license being sought. Each of the designations has different requirements for the number of hours worked to complete the apprenticeship. All of those requirements are listed here. The plumbing and piping related licenses with the fewest on-the-job training hours only require 2,000 hours or about one year. The rest all require 4,000 to 8,000 hours, or two to four years.
Connecticut Plumber Training Programs and Schools
Plumbers are responsible for a lot more than just fixing leaks or clogs. They design, install, and renovate systems that carry liquids or gasses, so they must know more than just the mechanics involved. They must know plumbing code. There are many programs to get the training you need to become a plumbing professional in Connecticut, and they are located all over the state.
Getting a plumbing or piping license in Connecticut requires you to complete an approved apprenticeship. The Department of Consumer Protection lists the education, exam, and training requirements on its website. As part of that you will need academic training, but can get it from many approved sources.
As mentioned above, the Connecticut Technical Education and Career System (CTECS) offers plumbing programs for high school students that count toward the required education of licensed plumbers. The Connecticut Technical Educational and Career System Apprenticeship Related Instruction program is fully approved by the state Department of Labor Office of Apprenticeship Training in the licensed occupational construction trades. Students in grades 11 and 12 are eligible to participate. They receive up to 720 hours of instruction upon successful completion of the program. Students may be able to receive 1,500 hours toward a career-affiliated apprenticeship upon graduation and employer acceptance. This program allows companies to hire students during the school day to work as a pre-apprentice in the plumbing and heating industry.
There are some other well-respected options statewide. The Connecticut Department of Labor provides a list. On that list, you’ll find the Porter and Chester Institute. That yearlong program costs roughly $25,000. You’ll also find the Construction Education Center in Plainville on the Department of Labor list. The Plumbing -P2 program is four years and costs about $8,000. The Industrial Management & Training Institute, serving Waterbury and the surrounding area, offers a plumbing program that is 926 total hours and costs about $22,000. The website says that graduates of the Plumbing Technician program will have learned the necessary skills for an entry-level apprenticeship position in residential, commercial, and industrial plumbing applications. Many IMTI graduates complete the program to pursue self-employment as a plumbing contractor.
You might be lucky enough to get one of the coveted apprentice spots with United Association Union of Plumbers, Fitters, Welders, & Service Techs Local 777 based out of Meriden. The apprenticeship program is five years long and meets all requirements of the state as well as the U.S. Department of Labor Apprenticeship standards. Apprentices will be paid a percentage of the journeyman wage and will receive periodic wage increases as they meet program requirements.
Program Prerequisites: You must be at least 18 years old and have a high school diploma or a GED.
On-the-Job Experience: While on the job, you will need to possess good customer service skills, be detail-oriented, have some mechanical capability, and be physically fit because the job can include some heavy lifting and hours of walking, standing, and working in tight spaces.

Connecticut Plumbing Contractor Licensing Exam Details
Both the trade and law and business examinations are administered by PSI. Once you are eligible to take the examination(s), you will need to mail the original license application (which can be found in the Candidate Information Bulletin), application fee, and any required documents to PSI. If all application requirements are met, PSI will issue you an Examination Eligibility postcard with instructions for scheduling and paying for the examination(s). It is your responsibility to contact PSI. You may go online at www.psiexams.com or call (855) 746-8171. Each exam is $59. If you are taking a contractor level exam, which requires both the trade portion and the Business and Law exam, the total is $118.
To prepare, PSI suggests that you start with a current copy of the Candidate Information Bulletin and use the examination content outlines as the basis of your study. Read/study materials that cover all the topics in the content outline and take practice tests. Take notes on what you study. Putting information in writing helps you commit it to memory, and it is also an excellent business practice. Also, discuss new terms or concepts as frequently as you can with colleagues. This will test your understanding and reinforce ideas. Your studies will be most effective if you study frequently for periods of about 45 to 60 minutes. Concentration tends to wander when you study for longer periods of time.
On the day of testing, you must bring two forms of identification that bear your signature, and one must also have your photograph. Your name as shown on the application form must exactly match the name on the photo I.D. used at the testing site.
Each of the exams is described in detail in the bulletin, including the number of questions and the time limit to complete it as well as which reference materials you may use and what items are not allowed in the testing centers. There are six locations listed. Two are in Connecticut—one in West Hartford and the other in Milford. There are four others in Auburn, Boston, Fall River, and Springfield, Massachusetts.
The Business and Law Examination is required for all contractor licenses. It is made up of 50 questions and has a two-hour time limit. It covers:
Licensing
Estimating and Bidding
Lien Law
Financial Management
Tax Laws
Labor Laws
Project Management
Contracts
Business Organization
Risk Management
Environmental and Safety
All of the plumbing, gas piping, and pipefitting exams have different numbers of questions and time limits depending upon the scope of the material. The unlimited contractor license has the most, with 80 questions and three hours to complete them. Check the Candidate Information Bulletin for details of what’s covered in each and what reference materials you should be studying to prepare. Most require knowledge of the International Plumbing Code and cover subjects like backflow, water heaters, and other such work.
All of the exams are open book and require a 70% to pass.
After passing your examination(s), you’ll need to submit the licensing fee indicated on the passing score report for your trade examination with all passing score reports to the Connecticut Department of Consumer Protection, and you will be issued your plumber license.
