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 limitations 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 heating 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 education or trade experience obtained outside Connecticut should follow the applicable state process for equivalent experience, training, or an equivalent out-of-state credential. Connecticut determines whether the submitted qualifications satisfy its licensing 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 services 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 authorized services only while employed by an appropriately licensed contractor.
