Gas Work That Meets the Australian Standard
Gas appliance installation is one of the more regulated tasks in plumbing — and for good reason. An incorrectly connected appliance can leak, fail a compliance check, or create a safety hazard in your home. At OneBookPlus Plumbing, we handle the full scope ourselves: supply line connection, regulator checks, flue or ventilation requirements, and final pressure testing. Unlike services that sub-contract gas work to a third party, our licensed gas fitters carry the job from start to finish. We work across Sydney for homeowners and landlords who need the installation done once, correctly, with documentation you can keep on file.
What we install
Gas Appliances We Connect and Commission
Gas cooktops and freestanding ovens
Bench or freestanding units connected to natural gas or LPG, including flexible hose and bayonet fitting where required.
Continuous flow hot water systems
Instantaneous gas hot water units mounted internally or externally, including flue installation and cold water connection.
Gas storage hot water units
Traditional tank-style gas hot water systems connected to the existing gas supply with pressure and temperature relief valve checks.
Outdoor BBQ and alfresco gas points
Fixed gas bayonet outlets installed at outdoor kitchens or alfresco areas, run from the existing domestic gas supply.
Gas space heaters and log fires
Flued and unflued gas heaters connected and commissioned, with flue installation handled where required.
New gas supply points
Running a new gas line from the meter to a new appliance location — including wall penetrations and concealed pipework where accessible.
How Your Gas Installation Works
Quote and site assessment
We confirm the appliance type, existing gas supply pressure, and any pipework or flue requirements before giving you a fixed price.
Supply line and connection
Our gas fitter runs or extends the supply line, fits the appropriate flexible connector or hard pipe, and secures the appliance in position.
Pressure test and leak check
Every installation is pressure-tested to Australian Standard AS/NZS 5601 and checked for leaks at every joint before the gas is turned on.
Commissioning and handover
We light the appliance, confirm correct operation, and walk you through any controls — then leave you with the compliance documentation.
Why Gas Installation Needs a Licensed Fitter
Safety and compliance
Unlicensed Gas Work Is Illegal in NSW
In New South Wales, all gas fitting work must be carried out by a licensed gas fitter. This includes connecting any appliance to a gas supply — even swapping a cooktop for a like-for-like replacement. OneBookPlus Plumbing holds the required NSW gas fitting licence and issues a Certificate of Compliance for every job, which your insurer or property manager may require.
- NSW gas fitting licence held by every technician on gas jobs
- Certificate of Compliance issued on completion
- Work meets AS/NZS 5601 Gas Installations standard
No sub-contracting
One Tradesperson Handles the Whole Job
Some plumbing companies quote the job and then send a sub-contracted gas fitter you have never met. At OneBookPlus Plumbing, the same tradesperson who assesses your installation carries it through to commissioning. That means no handover gaps, no miscommunication about what was quoted, and a single point of contact if anything needs following up after the job.
- No sub-contractors — our own licensed gas fitters on every job
- Consistent communication from quote to sign-off
- Direct callback if any issue arises after installation

What Sydney Homeowners Say
“Had a new gas cooktop installed after a kitchen renovation. The fitter arrived on time, ran a new flexible connection, pressure-tested the line, and had everything working within a couple of hours. The compliance certificate was emailed to me the same day.”
“I needed a continuous flow hot water system connected at a rental property in Parramatta. OneBookPlus handled the gas connection and the flue in one visit. My property manager had the compliance paperwork before the end of the week.”
“We wanted a fixed gas point installed at our outdoor kitchen. OneBookPlus ran the line from the meter, fitted the bayonet outlet, and tested everything properly. No mess, no fuss, and a clear explanation of what was done.”
