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 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 Skilled Trades BC and a Certificate of Qualification issued by Technical Safety BC.

This requirement is not retroactive and does not apply to existing Class B gasfitters with a valid Technical Safety BC certification.

Individuals who would like to obtain a Class B Gasfitter Certificate of Qualification from Technical Safety BC but do not hold a Gasfitter – Class B certificate of qualification with a red seal endorsement, or an equivalent out of province certification, should contact Skilled Trades BC to determine the appropriate pathway to obtain the certification.


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.

Applicants that hold a Gasfitter – Class B Certificate of Qualification with a Red Seal endorsement issued by Skilled Trades BC, or an equivalent out of province certification, will be eligible to write the Act, Regulations, and Directives (ARD) exam with Technical Safety BC.

Individuals with “in-progress” applications achieved without submitting a Gasfitter – Class B Certificate of Qualification with a Red Seal endorsement issued by Skilled Trades BC, or an equivalent out of province certification are eligible to complete their application with Technical Safety BC by submitting all required documentation and successfully completing the Class B Gasfitter certification exam.
