A gas fitter is qualified to work on natural gas lines. This can mean installing or repairing the gas lines themselves or the appliances that run on natural gas, such as a water heater or an oven. 

The term “gas fitter” is more commonly used in the U.K., Australia, and Canada. In the U.S., plumbers, natural gas plumbers, and HVAC technicians are qualified to work on natural gas lines. In some cases, a gas fitter won’t be a plumber and will only be qualified to work on the gas lines and not on other plumbing systems.

What Does a Plumber Do?

Plumbers are known for working on the plumbing system in your home, including water and sewage lines. They also fix leaks and install fixtures like toilets and faucets, but they can also install new gas lines and repair existing ones. 

Most trained and licensed plumbers are qualified to work on natural gas lines and gas-powered home appliances, such as hooking up gas dryers, water heaters, fireplaces, and HVAC systems. Before hiring a plumber to work on or install your gas lines, ask if they have the proper licensing and experience.

Pro Tip

A professional should always do gas hookups because of the serious dangers and risks involved. Signs you might need gas plumbing repairs are rust, damaged connections, or a gas smell. If you smell gas, turn off your appliance immediately and call a professional to inspect it.
