Class B Gas Fitter

Gas Certification

Overview

Effective January 1, 2025, the Gasfitter - Class B program became a Red Seal trade administered and certified by SkilledTradesBC. New applicants in BC who are looking to perform work as a Class B Gasfitter will require a Gasfitter - Class B Certificate of Qualification with a Red Seal endorsement issued by SkilledTradesBC and a Certificate of Qualification issued by Technical Safety BC.

The requirement to hold a Gasfitter - Class B Red Seal Certification applies only to applicants who have completed the Gasfitter - Class B Red Seal Apprenticeship pathway. This requirement is not retroactive and does not apply to existing Class B gasfitters with a valid Technical Safety BC certification.

Individuals who have not followed the Gasfitter - Class B Red Seal apprenticeship pathway may continue to apply for their Technical Safety BC certification until early 2026 by submitting either their Gasfitter - Class B Certificate of Apprenticeship or BC Certificate of Qualification issued by SkilledTradesBC, as well as a course completion document from a recognized training program.

A Gasfitter - Class B (120kW) Certificate of Qualification allows you to perform installations and alterations on the following gas systems, under a permit:

  • appliances with an input of 120 kW or less that display a certification mark or an approval mark issued under section 10 of the Act; and
  • piping and vents.

In addition, Class B gasfitters may perform electrical work that is restricted to the installation, repair, and maintenance of electrical wiring for solid, liquid, and gaseous fuel-fired heating equipment for any of the following:

  • connecting branch circuit wiring to the heating equipment's integral connection box, from a junction box or a disconnect mounted in close proximity to the heating equipment;
  • Class 2 circuit wiring up to a rated output of 100 Volt amps; and
  • low voltage controls or 24-volt thermostats.

To obtain this certificate, applicants will need to meet certain eligibility requirements, pass an exam, and submit an additional training credential or certificate.

As of January 1, 2025, new applicants that hold a Gasfitter - Class B Certificate of Qualification with a Red Seal endorsement issued by SkilledTradesBC will be eligible to write the Acts, Regulations, and Directives (ARD) exam with Technical Safey BC.
