Do I need technical inspection services approval for gas work in New Brunswick?

Yes, absolutely — all gas work in New Brunswick requires both a licensed gas fitter and Technical Inspection Services (TIS) approval. This is a strict provincial requirement that applies to propane, natural gas, and medical gas installations throughout the province.

Here's what you need to know about the two-step process:

Step 1: Licensed Gas Fitter Required
Only contractors holding a valid compressed gas licence from TIS can legally perform gas work in New Brunswick. This includes installing, altering, or repairing any gas appliance, piping, or system. Homeowners cannot do their own gas work — even simple appliance connections require a licensed professional.

Step 2: TIS Permit and Inspection
Before any gas work begins, your contractor must obtain a gas installation permit from TIS. After the work is completed, TIS conducts a mandatory inspection before the system can be put into service. No gas system can be legally operated without passing this inspection — it's both a safety and insurance requirement.

Getting Started
Contact TIS at 1-888-659-3222 (Monday-Friday, 8:15am-4:30pm) or email TISFTN@gnb.ca to discuss permit requirements for your specific project. They have Service New Brunswick centres in Fredericton, Saint John, Moncton, Miramichi, Bathurst, Campbellton, Edmundston, and Woodstock for in-person service.

Why This Matters
Gas work carries serious safety risks — leaks can cause explosions, carbon monoxide poisoning, or fires. TIS licensing ensures your contractor has proper training, and their inspection verifies the installation meets safety codes. Working without permits can void your home insurance and create liability issues if something goes wrong.

Common Gas Projects Requiring TIS Approval
This includes furnace installations, water heater replacements, gas fireplace installations, BBQ gas line connections, pool heater hookups, and converting from oil to gas heating systems.
