What’s the Difference Between a Plumber and a Gasfitter in Australia?

When you experience a burst pipe, a blocked drain, or need a new hot water system installed, your first instinct might be to call a plumber. But what if the issue involves gas fittings, like a gas cooktop or heater? Do you still call a plumber, or do you need a gasfitter?

In Australia, plumbing and gasfitting are closely related trades, but they are not the same thing. While many licensed plumbers are also qualified gasfitters, the two roles have distinct responsibilities, licensing requirements, and areas of expertise.

In this article, we’ll break down the key differences between a plumber and a gasfitter in Australia, explain why it matters, and help you understand when to call each professional. Whether you’re a homeowner, property manager, or aspiring tradesperson, knowing the difference is crucial for safety, compliance, and peace of mind.

What is a Plumber?

A plumber in Australia is a licensed tradesperson who installs, repairs, and maintains systems related to water, sewage, and drainage. Their work ensures safe and hygienic water supply and waste management in residential, commercial, and industrial buildings.

Common Plumbing Tasks:

• Installing and repairing toilets, taps, sinks, and showers

• Unblocking drains and pipes

• Installing and maintaining water heaters

• Fixing burst or leaking pipes

• Setting up irrigation systems

• Connecting appliances like dishwashers and washing machines

Plumbers are essential to modern infrastructure, keeping water flowing safely and efficiently through homes and businesses.

What is a Gasfitter?

A gasfitter is a tradesperson trained and licensed to work on gas systems and appliances. This includes the installation, repair, and maintenance of gas pipes, regulators, appliances, and flues.

Common Gasfitting Tasks:

• Installing gas lines and gas meters

• Connecting gas appliances such as cooktops, ovens, and BBQs

• Installing gas heating systems and hot water units

• Performing gas leak detection and repairs

• Testing and certifying gas systems for safety and compliance

Because gas is highly flammable and potentially dangerous, gasfitting requires specialised training and strict adherence to safety standards.

Are Plumbers and Gasfitters the Same in Australia?

Not exactly — but they can be. In Australia, many plumbers are also qualified gasfitters, but not all are. Plumbing and gasfitting are considered separate trades under the law, each requiring its own license and training.

Some tradespeople hold dual licenses, meaning they are legally permitted to perform both plumbing and gasfitting work. Others may only hold one, in which case they can only legally perform the tasks specific to their license.

Example:

• A licensed plumber can fix a leaking tap or install a new toilet.

• A licensed gasfitter can install a gas heater or detect a gas leak.

• A tradesperson with both licenses can do both jobs safely and legally.

Licensing and Training Differences

Plumbing Licensing in Australia

To become a licensed plumber, an individual must complete:

• A Certificate III in Plumbing (typically through a 4-year apprenticeship)

• On-the-job training under supervision

• A licensing exam administered by the relevant state authority

Plumbing licenses are issued by different state bodies, such as the VBA (Victoria), QBCC (Queensland), or Fair Trading (NSW).

Gasfitting Licensing in Australia

To become a licensed gasfitter, a person must:

• Complete additional gasfitting units as part of or after the plumbing apprenticeship

• Undertake practical training with a licensed gasfitter

• Pass relevant gasfitting exams and apply for the specific gasfitting license

In most states, gasfitting is considered an endorsement on a plumbing license, not a standalone trade license.

Scope of Work: Plumber vs Gasfitter

Here’s a quick comparison of the services each trade typically handles:

Why It’s Important to Hire the Right Professional

Hiring the wrong tradesperson can lead to:

• Safety hazards (e.g. gas leaks, water damage, mold)

• Code violations (leading to insurance issues or legal consequences)

• Failed inspections during renovations or sales

• Voided warranties on appliances or plumbing systems

Always ensure your tradesperson is qualified for the work you need done. For gas-related jobs, only use licensed gasfitters — it’s the law.

How to Check if Your Tradesperson is Licensed

Each Australian state has an online register where you can verify a plumber or gasfitter’s credentials. Here are a few:

• Victoria (VBA): vba.vic.gov.au

• New South Wales (Fair Trading): fairtrading.nsw.gov.au

• Queensland (QBCC): qbcc.qld.gov.au

When hiring through platforms like PlumbersHQ, all listed professionals are pre-verified, licensed, and insured — giving you confidence and peace of mind.

Common Projects That Require Both Skills

Many modern installations require both plumbing and gasfitting expertise. For example:

1. Gas Hot Water System Installation

This project involves connecting to the water supply (plumbing) and connecting to the gas supply (gasfitting).

2. Kitchen Renovations

Installing a sink (plumbing), dishwasher (plumbing), and gas cooktop (gasfitting) will likely require a dual-licensed tradesperson or a coordinated team.

3. Outdoor Kitchens and BBQs

Connecting water for a sink and gas for the BBQ involves both trades.

In these scenarios, working with a dual-licensed professional or team is the most efficient — and legal — choice.
