What are the Types of Plumbing Licenses in Illinois?

These are the types of plumbing licenses in Illinois:

  • Apprentice plumber license

    Upon getting the required experience and passing the exam, you can move up to get licensed as a plumber. This allows you to provide plumbing services without having to supervise you.
  • Plumbing contractor license

    This license is for those who want to start their own plumbing business. So if you are looking to take plumbing contracts from clients, you need to have a contractor’s license.
  • Retired plumber license (Provided only by IDPH)

    Retired plumber license is for licensed plumbers over the age of 62. This license helps you to take a break from providing plumbing services without getting your license expired.
