04 Jun Why a Dual Licensed Plumber & Gas Fitter Saves You Time & Money
Dual licensed plumbers and gas fitters are hard to come by. Most people don’t know this until they’re mid-renovation or standing in a commercial kitchen that’s half-fitted out: plumbing and gas fitting are two separate licensed trades in Queensland. A plumber cannot legally perform gas fitting work without a gas licence, and vice versa. That matters a great deal when you’re planning a kitchen renovation, commissioning a commercial installation, or dealing with an emergency that involves both.
At Alexander Gas and Plumbing Co, we hold both Queensland Plumbing Licence 28840 and Gas Licence L31 902. That dual-licence setup is our primary point of difference, and I want to explain exactly what it means for you in practical terms – because it’s not just a marketing point. It directly affects how long your job takes, how much it costs, and how smoothly it runs.
Why Plumbing and Gas Are Separate Trades in Queensland
In Queensland, gas fitting is regulated under the Gas Supply Act 2003 and associated regulations. To perform gas fitting work legally – connecting appliances, installing gas lines, fitting regulators, commissioning burners – a tradesperson must hold a current Queensland gas licence issued by the Petroleum and Gas Inspectorate.
Plumbing work is separately regulated under the Plumbing and Drainage Act 2018, with licences issued by the QBCC. The two licensing systems are entirely independent. A qualified plumber with 20 years of experience is not permitted to touch gas appliances unless they also hold the gas licence. This creates a genuine practical problem for clients, because most jobs involving gas also involve plumbing, and most plumbing contractors are not gas-licensed.
Richard Alexander holds both qualifications. He is a Registered Master Plumber with over 30 years of experience, holds Queensland Plumbing Licence 28840, Gas Licence L31 902, QBCC Licence 12 654 79, and Building Assets and Services Contractor Licence 860 066. Every member of the Alexander Gas and Plumbing Co team is fully licensed and qualified.
What This Means for Residential Clients
For homeowners, the dual licence most commonly matters in kitchen renovations and hot water system upgrades. A kitchen renovation that includes a new gas cooktop or oven requires gas fitting work to connect the appliance, test for leaks, and ensure the installation complies with Australian Standards. If your plumber is not gas-licensed, that work has to wait for a separate contractor – another booking, another wait, another call-out fee, and the possibility of the two tradespeople needing to coordinate their schedules.
Hot water system upgrades from electric to gas – or installation of an instantaneous gas hot water system – require both plumbing and gas connections. A gas-boosted solar system requires both as well. Outdoor BBQ bayonets, indoor gas heaters, and portable gas appliances all require a licensed gas fitter. With us, all of this is handled by one team on one visit.
The practical effect is fewer days of disruption, one point of contact, and a single invoice rather than separate bills from two contractors who may not have communicated particularly well with each other.
What This Means for Commercial Clients
The dual-licence advantage is amplified significantly in commercial environments. A commercial kitchen installation in a restaurant, hotel, or food court typically involves substantial gas fitting work – high-output burners, wok rings, commercial ovens, gas grills, and associated infrastructure including regulators, gas manifolds, and flexible connections. That same installation also involves drainage, water supply, grease traps, and hot water connections.
If you are commissioning or refitting a commercial kitchen with a contractor who holds only a plumbing licence, you will need a separate gas fitter involved in the project. That means two separate trades to coordinate, two scheduling dependencies, and two separate defects or warranty conversations if something is not right after installation.
We handle commercial kitchen installations across Brisbane and South East Queensland as a single trade. We design, install, and commission both the plumbing and gas systems, and we provide the compliance documentation required for council and building certification. For commercial clients, this is a substantial advantage in terms of project efficiency and accountability.
Emergency Situations
The dual-licence advantage matters most in emergencies because emergencies don’t respect trade boundaries. A commercial kitchen gas failure that also involves flooding from a failed water connection needs both trades. If the business responding to your call can only legally work on one half of the problem, you’re making two emergency calls and waiting on two contractors.
We respond to emergency plumbing and gas calls 24/7 across Brisbane. One call, one team, full resolution – for both systems.
The Compliance and Documentation Angle
All gas fitting work in Queensland requires compliance documentation. Form 15 certificates are issued for notifiable gas work. For commercial installations, these records are part of the building’s compliance file and are required by building certifiers, insurance companies, and government inspectors. A licensed gas fitter is responsible for their own compliance documentation.
When you engage a dual-licensed contractor like us, the compliance paperwork for both the plumbing and the gas work is coordinated through a single engagement. For commercial clients managing multiple sites or complex builds, that administrative clarity has real value.

Frequently Asked Questions
Can any plumber connect a gas appliance in Queensland?
No. In Queensland, connecting gas appliances — including cooktops, ovens, hot water systems, heaters, and BBQ bayonets — requires a current Queensland gas licence. A plumber without a gas licence cannot legally perform this work, regardless of their experience. Always verify that your contractor holds the appropriate licence for the work being done.
How do I verify a Queensland plumbing or gas licence?
Queensland plumbing licences are held by the QBCC and can be searched at the QBCC website. Gas licences can be verified through the Queensland Petroleum and Gas Inspectorate. Our licence numbers are: Plumbing Licence 28840, Gas Licence L31 902, QBCC 12 654 79.
Do you handle both residential and commercial gas fitting?
Yes. We install and service gas systems across residential, commercial, and industrial environments. This includes domestic kitchen appliances, commercial kitchen fitouts, gas heating systems, outdoor entertaining areas, and large-scale commercial gas infrastructure.
What is a Form 15 and do I need one?
A Form 15 is a compliance certificate issued by a licensed gas fitter for notifiable gas work. It confirms the work meets Queensland gas safety regulations. For most domestic and all commercial gas installations, a Form 15 is required. We issue Form 15 certificates for all notifiable gas work as a standard part of our service.
