State Requirements

The Connecticut S-6 credential is a limited journeyperson license associated with qualifying hot-water and steam heating work. The classification focuses on heating equipment, related piping, controls, insulation, maintenance, testing, and system operation within the limits established for the credential.

The S-6 license is a journeyperson credential and does not provide independent contracting authority. The license holder must perform authorized work while employed by a contractor licensed for the applicable work.

Applicants must complete a registered apprenticeship program or demonstrate equivalent experience and training accepted by the Connecticut Department of Consumer Protection. Supporting records may be required to document classroom instruction, supervised on-the-job training, apprenticeship completion, or equivalent qualifications.

Applicants with training or experience obtained outside Connecticut should follow the state’s applicable procedures for equivalent experience, education, or an equivalent out-of-state credential. Connecticut determines whether the submitted qualifications satisfy its requirements.

The S-6 classification is limited in scope. It does not provide unlimited authority to perform every type of heating, cooling, refrigeration, fuel gas, oil burner, piping, or air-conditioning work. License holders must remain within the work authorized by the credential.

Holding an S-6 license does not replace other occupational credentials that may be required for work outside the approved scope. Journeypersons should perform only authorized work under the employment of an appropriately licensed contractor.
