We rarely think about the plumbing in our homes and businesses unless something goes wrong with it. Plumbers become the heroes who rush to our rescue when that happens. We simply cannot live without these essential experts. As a result, most states agree there should be a minimum amount of training and education for all plumbers. 

According to the U.S. Bureau of Labor and Statistics, there are 469,000 plumbers nationwide and Kentucky employs 4,740 of them. The national number is projected to grow 2 percent from 2021 to 2031 adding 9,100 of these skilled workers to the ranks. In Kentucky, according to CareerOneStop, the U.S. Department of Labor’s job search website, the projected growth rate is more than twice that at 5% for Plumbers, Pipefitters, and Steamfitters.

Contractors are struggling to find skilled tradesmen like plumbers, electricians, and HVACR professionals. In fact, 60% of firms in the United States and in Kentucky had unfilled hourly craft positions, according to the Associated General Contractors of America, 2020 AGC-Autodesk Workforce Survey. So, if you get the training you need you should have a variety of jobs to choose from when you’re ready.

If you’re considering taking this career path, you’ll need to understand the licensing regulations and how to navigate the terrain. In Kentucky, it will take you at least two years as an apprentice before applying for a journeyman license, but then you will have started a career with job security.

How to Get a Plumbing License in Kentucky

Kentucky follows the apprenticeship model of many other states. For every licensing level, you must be at least 18 years old.

WORK EXPERIENCE: The state requires apprentices to document two years of experience before applicants can take the journeyman licensing examination. That documented work must be under:

  • The direct supervision of at least one journeyman plumber; and

  • The general supervision of a master plumber

You can begin the process by finding a program sponsor as an apprentice/entry-level worker or through a vocational school or community college. Completion of a two-year plumbing course counts as one year of experience. Sponsors of both full-length traditional programs and shorter programs can be found on the Kentucky Education & Workforce Development Cabinet’s Apprenticeship page. There are also spreadsheets through this link that will help you identify possible apprentice opportunities.

Certification tests are rigorous and thorough, so additional formal education at a college or trade school may be a more helpful first step in your training to be a plumber. Employers often state a preference for apprentices who have graduated from a relevant trade school or technical college.

TAKE LICENSING EXAM AND PAY EXAM FEE: After getting the documented work experience as an apprentice, you can register to take the plumbing examination. You must include the exam fee of $50 for the journeyman plumber examination payable to the Kentucky State Treasurer, and provide a passport-sized color photograph taken within the past six months.

APPLY FOR LICENSE: Once you’ve successfully passed your exam and have all the other documentation of the required work experience, you may apply for your journeyman license. The annual fee for a journeyman license is $60. All licenses expire at the end of the license holder’s birth month. You can work as a journeyman indefinitely. You simply need to renew your license every year and work under the supervision of a master plumber.

ADDITIONAL WORK EXPERIENCE FOR MASTER LICENSE: A candidate for master plumber must have had a valid journeyman plumber license for two years within the five years preceding the exam and have been employed in the plumbing trade for the past two years or be a registered mechanical engineer.

TAKE LICENSING EXAM AND PAY EXAM FEE: After getting the documented work experience as a journeyman, you can register to take the plumbing examination. You must include the exam fee of $150 for the master plumber examination payable to the Kentucky State Treasurer, and provide a passport-sized color photograph taken within the past six months.

APPLY FOR MASTER PLUMBER LICENSE: Once you’ve passed the exam and have all the other documentation you need for demonstrating you’ve fulfilled the work experience requirements, a journeyman can apply for a master plumber license. The annual fee for a master license is $250. All licenses expire at the end of the license holder’s birth month. You will need to renew your license every year.

PROVIDE PROOF OF INSURANCE: Master plumbers must provide proof of general liability insurance of at least $250,000, and submit proof of compliance with workers' compensation and unemployment insurance laws of the Commonwealth.

How Long Does it Take to Get a Plumbing License in Kentucky?

It will take a minimum of four years to qualify to take the master plumber license exam in Kentucky and a minimum of two years to qualify to take the journeyman exam. However, you will be working and accumulating the necessary experience—and can be earning money—the whole time.

Kentucky 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. There are many programs to get the training you need to become a plumbing professional in Kentucky. You’ll need two years as an apprentice. 

You can find a contractor or company with an opening or enroll in a trade school or union apprenticeship program. Those programs can often help connect you with a licensed master plumber to oversee your apprenticeship after you’ve completed the course work for a certificate or associate’s degree. It’s not unusual for community colleges to offer plumbing degree programs in combination with a closely related field like gas technology or heating. Completion of a two-year plumbing course counts as one year of experience. 

You’ll learn about plumbing systems including:

  • Underground water supply

  • Stormwater

  • Sewer drainage

  • Fixture installation

  • Waste and vent piping both inside and outside of buildings

  • Residential and service plumbing

Any program should also cover OSHA safety training, detailed instruction in chemistry, mathematics, physics, blueprint reading and drafting, in-depth examination of state codes, and advanced training about water treatment systems, water heaters, plumbing appliances, and plumbing fixtures.

  3. The other state agrees to reciprocate with Kentucky.
