Gas fitters install, service and repair gas appliances and piping systems. Work includes running gas lines to appliances, installing hot water systems, heaters and cooktops, testing for leaks and compliance, and completing certification documentation required for all gas installation work.

A Certificate III in Plumbing with a gasfitting specialisation, typically gained through a plumbing apprenticeship, is the standard trade qualification. A gasfitting licence from your state regulator is required to work independently and certify completed gas installations. Ongoing education keeps licensed gas fitters current with evolving safety standards.

Meticulous attention to safety, given the serious risks associated with gas leaks and faulty installations, alongside strong problem-solving skills diagnosing appliance faults. Clear communication with customers about safety issues and compliance requirements matters considerably. A methodical, careful approach under time pressure defines reliable gas fitting work.

Plumbing contractors employ most gas fitters across residential and commercial installation and service work, alongside gas appliance retailers and specialist heating and hot water service companies. Builders also engage gas fitters for new construction projects. Emergency call-out work also generates steady additional income for many gas fitters.

Gas fitters progress to leading hand and supervisor roles, then business ownership running their own plumbing and gasfitting business. Specialising in commercial or industrial gas systems, or LPG installations, opens further specialist, well-rewarded career pathways. Strong safety records and reliability often accelerate business growth over time.
