Our gas fitters work in government buildings, office complexes, industrial facilities, strata properties, hospitality venues and educational institutions.

Gas Fitting, Installation & Compliance for Commercial & Government Facilities
PJC Plumbing's gas fitting services in Sydney cover the installation, testing and certification of commercial gas systems. That covers gas line installation, appliance connections, isolation valves and gas bayonets on LPG or natural gas. New pipework is pressure tested, then purged and commissioned before any appliance is lit. When the work is finished, you receive a Gas Certificate of Compliance.
Commercial gas work in NSW has to meet AS/NZS 5601.1. Under the WHS Act, the people who own or manage a building also have a duty to keep its services safe. Insurers expect to see current compliance certificates. Missing paperwork tends to surface during a claim or a tenancy change, which is why scheduled gas compliance checks in Sydney are worth booking.
As a licensed gas plumber in Sydney, PJC Plumbing handles commercial gas compliance and plumbing in commercial kitchens, industrial plant rooms, government offices, hospitals, aged care homes, schools and strata complexes. Every gasfitter we send holds a current NSW Fair Trading licence. The company is certified to ISO 9001, ISO 14001 and ISO 45001, and those systems are externally audited.
What Causes Gas Issues in Commercial Properties?
Most gas faults the PJC team finds in commercial buildings come from a fairly short list of causes:
-
Ageing or corroded pipework: Many older Sydney buildings still run their original steel gas lines, and decades of corrosion eventually show up as slow leaks or falling pressure.
-
Faulty appliance connections: Flexible hoses wear out, and fittings work loose, especially on kitchen equipment that gets pulled out for cleaning every night.
-
Inadequate gas pressure: Supply lines are usually sized for the equipment a building had when they went in. Add a combi oven or a second boiler years later and the pipework may not carry enough gas, so flames burn low and appliances cut out.
-
Root pressure and ground movement on buried lines: Gas lines buried near trees or garden beds are under constant load from roots and shifting soil. Over time, that can crack a joint.
-
Compliance gaps: A system altered by someone unlicensed, or one that hasn't been inspected in years, may no longer meet AS/NZS 5601.1. Owners often find out during a fit-out or when the property goes up for sale.
-
Tripped safety shut-off systems: Automatic shut-off valves close when they detect a leak, a pressure fault or a failed exhaust interlock. The gas stays off until a licensed gasfitter finds the cause and resets the system.
-
Outdated meters and regulators: Meter and regulator sets installed decades ago are often too small for the gas a building uses today. Replacing them usually means coordinating with Jemena or the site's LPG supplier.

24/7 Emergency Gas Plumbing for Commercial Properties
A gas leak can mean evacuating a building, and a failed supply can shut a commercial kitchen halfway through lunch service. PJC Plumbing runs a 24/7 emergency gas plumber service across Sydney for these situations. The gasfitter's first job on site is to make the area safe and isolate the fault. Supply is restored only after the system has been tested.
Emergency callouts cover gas leak detection, gas leak repair on commercial property pipework, appliance isolation and pressure restoration. Once the repair is done, the gasfitter completes the compliance paperwork, so an after-hours job doesn't leave a gap in your records. PJC's emergency gasfitters are licensed and insured. They follow the same documented WHS procedures at 2 am as on a planned daytime job.
Our Gas Plumbing Services Include:
At PJC Plumbing, we provide a complete range of licensed gas plumbing services for commercial, government, and industrial clients across Sydney:
-
Gas line installation and commissioning: New supply lines, manifolds and distribution pipework, installed to AS/NZS 5601.1 and pressure tested before commissioning.
-
Gas leak detection and repair: Electronic detectors and gas pressure testing pinpoint leaks in pipework, appliance connections and underground runs. PJC documents each repair, so you have a record ready if your insurer asks.
-
Gas compliance certificates: Inspection of new and altered installations, any rectification the system needs, and a Gas Certificate of Compliance for your Sydney property confirming it meets AS/NZS 5601.1.
-
Commercial gas appliance installation: Connection of commercial cooktops, combi ovens, boilers, industrial burners and gas hot water plant. Type B appliances receive the additional approval they need before they can operate.
-
LPG and natural gas system upgrades: Conversions between LPG and natural gas, regulator upgrades, and gas meter installation and sizing. PJC coordinates any meter work with Jemena or your LPG supplier.
-
Preventative gas maintenance plans: Scheduled inspections, pressure tests and appliance checks that pick up wear before it turns into a leak or an audit finding.
Gas Plumbing for Government & Institutional Buildings
Gas work in government and institutional buildings needs licensed gasfitters, tight WHS controls and a complete paper trail. PJC Plumbing has delivered government gas plumbing contracts in Sydney across council buildings, hospitals, aged care facilities and TAFE campuses, and knows how procurement and site safety management plans work. Every gasfitter holds a NSW Fair Trading licence. Asset managers get their certificates of compliance at sign-off, ready for the next audit.
Gas Fitting for Commercial Kitchens & Hospitality Venues
Commercial kitchens are among the riskiest places for gas in any building, because burners run hot for long shifts in tight, busy spaces. PJC Plumbing's licensed gas fitters install, service and certify gas systems in restaurants, hotels, aged care kitchens and institutional dining halls across Sydney. The work includes connections for high-output equipment, isolation valves, and interlocks between the gas supply and mechanical exhaust where AS/NZS 5601.1 requires them.
Industrial Gas Plumbing & Compliance
Industrial gas plumbing in Sydney calls for gasfitters who can work safely around process gas, bulk LPG storage and high-volume natural gas supply. PJC Plumbing works in plant rooms, manufacturing facilities and large commercial sites. Typical jobs include gas installation, burner and gas booster connections, and pressure testing. Compliance documentation is prepared to satisfy insurers, SafeWork NSW and site safety rules.
Every commercial property has unique gas supply requirements, load demands, and compliance obligations. PJC Plumbing delivers tailored gas plumbing solutions for each type of facility.
Gas Systems Tailored to Your Building Type
This allows us to measure your appliance load and supply pressure, then confirm whether the existing pipework and meter can handle it, including equipment you plan to add.
This allows us to design and install gas systems for strata and multi-tenancy buildings where each tenancy has its own isolation point and, where required, its own meter.
This allows us to keep your gas systems certified and safe all year.

Gas smell inside the building
A gas smell indoors usually means there is a leak or a faulty appliance connection. Gas suppliers add an odorant to natural gas and LPG so that people notice leaks, so treat the smell as real. Get people away from the area and avoid electrical switches and open flames. If you can reach the meter safely, turn the gas off, then call PJC Plumbing from outside the building.
Pilot lights going out repeatedly
A pilot light that keeps going out usually points to low gas pressure, a faulty regulator or a worn part such as the thermocouple. Relighting it might hold for a few minutes, but whatever put it out is still there. Leave the appliance off until a licensed gasfitter has checked the supply pressure and inspected the unit. It should go back into service only after the fault is repaired.
Unexplained increases in gas bills
When gas bills climb, and usage hasn't changed, a slow leak or an appliance burning more gas than it should is the likely cause. Leaks in concealed or buried pipework can run for months before anyone notices. A pressure test isolates the system one section at a time to show whether gas is escaping and where.
Gas appliances failing to reach operating temperature
Gas appliances that can't reach operating temperature are usually short on gas pressure or volume. In a commercial kitchen, you see it as orders backing up during the dinner rush. On an industrial line, it can mean wasted product. PJC Plumbing measures pressure at the meter and at the appliance, then checks pipe sizes and regulator settings to find the restriction.
