Gas Line Installation

Gas Line Installation near you

Gas line installation in Australia is gasfitting, and the everyday jobs are smaller than the phrase suggests: a new point for a gas cooktop, a bayonet fitting for a space heater, a line out to the barbecue on the deck, an extension to reach a relocated kitchen, or new consumer piping through a renovation. The pipework from the meter or the LP gas cylinders to each appliance is the consumer piping, and it is the gasfitter's work from end to end.

This type of work often has to be done by a licensed or certified trade. Ask to see licences and proof of insurance before work starts.

Two supply arrangements exist side by side here. Reticulated natural gas serves most capital city suburbs, while LP gas from cylinders serves much of regional and rural Australia and plenty of outer suburbs with no gas main. They are not interchangeable: appliances are built or converted for one or the other, the pressures differ, and cylinder installations bring their own siting and clearance rules.

The one constant is licensing. Gasfitting is a licensed trade in every state, the technical rules come from AS/NZS 5601, and a certificate or notice follows the completed work in state after state. If you take nothing else from this guide, take the habit of asking to see the licence card before the work and asking for the certificate afterwards, because between them they are most of your protection.

The gas line jobs Australian households actually ask for

  • A new gas point for a cooktop or a freestanding cooker, usually as part of a kitchen renovation.
  • A bayonet point for a space heater or a gas log fire in a living area.
  • A barbecue point on a deck, patio or outdoor kitchen, replacing the routine of swapping cylinders.
  • Extending or rerouting existing consumer piping when a kitchen, laundry or appliance moves.
  • Running a line to a gas hot water unit, a pool or spa heater, or an outdoor heater.
  • Converting an installation between natural gas and LP gas, which is appliance work as well as pipework and is never a matter of just changing the hose.
  • Upgrading undersized consumer piping when a household adds an appliance and the existing line can no longer feed everything at once.
  • Disconnecting and making safe redundant gas points during an electrification upgrade or a renovation.

How a gasfitter plans and installs consumer piping

  • Working out the total connected load, meaning every appliance the line will feed at once, rather than sizing the pipe for the new appliance alone.
  • Checking the supply at the meter or the cylinder installation is adequate for that load, and arranging an upgrade with the distributor if it is not.
  • Planning the route so the pipe is supported, protected and accessible where it needs to be, and deciding where it can be concealed and where it cannot.
  • Selecting materials and fittings suited to the run, including the treatment of any section passing underground or through a wall.
  • Installing isolation so each appliance can be shut off on its own without turning off the whole house.
  • Pressure testing the completed installation and purging it properly before anything is lit.
  • Connecting and commissioning the appliances, confirming they burn correctly, and checking for spillage of combustion products where the appliance is flued.
  • Issuing the certificate or notice the state requires and handing over the paperwork with it.

Gasfitting licences and AS/NZS 5601, state by state

Every state licenses this work and several make a point of saying there is no small-job exemption. In New South Wales you need a licence or certificate to do any plumbing, draining or gasfitting work regardless of the cost of the work, and gasfitting work is defined there as work involving the installation, alteration, extension or repair of a gas installation, the installation, alteration, extension, removal or repair of any flue, and the connection of a gas installation to, or its disconnection from, a gas supply point. In Queensland you need a licence or authorisation before you do any gas work, regardless of whether the work is residential, commercial or industrial, with gas work meaning any work involved in installing, removing, altering, repairing, servicing, testing and certifying the gas system of a gas device, and the QBCC gasfitting licence covering installing, commissioning, maintaining, testing, altering, repairing and servicing a gas system in any building alongside a separate occupational licence from the Chief Gas Examiner and Resources Safety and Health Queensland. Victoria puts it as bluntly as any regulator does: Energy Safe Victoria states that gas and electricity are inherently dangerous, that it is illegal and potentially fatal for unlicensed and unqualified people to undertake any gasfitting or electrical work, and that homeowners and consumers must always use a licensed or registered gasfitter.

The technical rules are national in substance. Energy Safe Victoria confirms that AS/NZS 5601.1 and AS/NZS 5601.2 are the prescribed standards under regulation 14 of the Gas Safety (Gas Installation) Regulations 2018, that AS/NZS 5601.1:2022 is the current general installations edition, and that from 30 March 2023, after a six-month transition period, work is assessed against the new standard, with gasfitters expected to comply in full with the 2022 edition. It also notes that amendments to the standards are automatically adopted under the regulations when published and become legally enforceable from that date, which is why a gasfitter's currency matters and a decade-old habit is not a defence.

LokalMatch is where the search starts, not where the checking ends. You describe the gas work once, saying what appliance the line is for, whether the house is on natural gas or LP gas, where the meter or cylinders sit and how far the new point is from them, and matched licensed gasfitters in your area contact you directly. Those businesses pay for the requests they receive. LokalMatch does not carry out gas work, does not set or quote prices, and does not vet, rank or recommend any business, so asking to see the licence card, reading the registered classes on the back and confirming the licence on your state regulator's register is your part of the job.

Undersized lines, appliance clearances and other things that go wrong

The most common quiet fault in an Australian house is a line that was adequate when it was installed and is not adequate now. Add a cooktop to a line already feeding a heater and a hot water unit, and the appliances start competing: burners drop off when something else fires, a heater struggles on the coldest evenings, or an appliance that used to burn cleanly begins to soot. This is why a competent gasfitter asks what else is connected before quoting a new point, and why the cheapest quote is sometimes the one that has not asked.

Clearances are the second recurring problem, particularly in kitchens, and they are measurable rather than a matter of taste. Energy Safe Victoria's guidance for gas cooking states that rangehoods must be at least 600 mm above the cooking appliance, that exhaust fans must be 750 mm above the appliance, and that burners must have clearances of 200 mm unless the nearby wall or surface is suitably protected, adding that your gasfitter can ensure your kitchen meets these standards. Renovations are where these get broken, usually by a joiner or a designer rather than by the gasfitter, and usually after the gas point has already been installed.

Ventilation is the third. Energy Safe Victoria notes that gas cookers consume air and release combustion products into the room and can make the room stuffy if there is inadequate ventilation, and that dirty, old and un-serviced gas cookers operating in a sealed environment have an increased risk of carbon monoxide spillage. Sealing a house up for energy efficiency while adding gas appliances is a combination worth raising with the gasfitter explicitly. On the LP gas side, the common faults are at the connection rather than in the pipework: Energy Safe Victoria's household leak check for a cylinder connection is a squeezy bottle of soapy water made with dishwashing liquid, squirted on the connection, where bubbles form if gas is escaping.

If you smell gas, or an appliance starts behaving badly

A smell of gas is not something to investigate at leisure. Get people out of the building, do not relight anything, and call for help from outside; Energy Safe Victoria directs people to call 000 for life-threatening emergencies. Do not attempt to find or fix a leak on consumer piping yourself, because unlicensed gas work is illegal in every state and a repair that looks fine can fail later under pressure.

With LP gas cylinders, a few habits prevent most incidents. Energy Safe Victoria's guidance is that gas will not flow unless the valve is connected to the barbecue's hose assembly, and that the cylinder valve handle must be closed before disconnecting the hose assembly for replacement or refilling. It also notes the introduction of the LCC27 valve to improve safety and reduce the risk of barbecue fires and accidental gas leakage from LPG cylinders, while cylinders with the current Type 21 POL valves may continue to be used.

Carbon monoxide is the other emergency and it gives no warning of its own. The Victorian Department of Health advises that if you suspect you may be affected by carbon monoxide from a gas appliance you immediately turn it off, open the doors and windows to ventilate the area, leave the property and seek medical advice immediately, calling 000 in an emergency, and lists the symptoms as tiredness, shortness of breath, headaches, dizziness, nausea, weakness, confusion or chest pain. If new gas work has just been done and people start feeling unwell at home, treat the two as connected until a gasfitter has shown otherwise.

The certificate that follows the work, in Victoria, Queensland and Western Australia

This is the part of a gas job most worth being fussy about, because the certificate is the record that the work was done by someone entitled to do it and to the prescribed standard. In Victoria, Energy Safe Victoria states that after installing a gas appliance the licensed gasfitter must give you a compliance certificate, that your copy of the compliance certificate protects you if any problems arise later due to faulty installation, and that being offered a cheap job excluding the cost of the compliance certificate is an offence under the Building Act 1993. That last point is worth remembering, because the discount is not a saving: it removes the document you would need later.

Queensland and Western Australia have their own equivalents. In Queensland, when a licence holder completes an installation they use the regulator's portal to issue the owner or operator of the system with an original copy of the gas system compliance certificate, and also the operator of the system or network where the system is supplied by a distribution system or fuel gas network. In Western Australia, the submission of Notices of Completion is a requirement of the Gas Standards (Gasfitting and Consumer Gas Installation) Regulations 1999, and a gas fitter must install an appliance in a suitable location and in accordance with the manufacturer's instructions or recommendations. Ask which document applies in your state and ask for it by name when you agree the job, not after the gasfitter has driven away.

The Australian Consumer Law sits behind all of it. The ACCC explains that the basic rights covered by consumer guarantees cannot be taken away by anything a business says or does, that service providers must carry out all services using an acceptable level of care and skill, that services and any resulting products must be fit for any stated purpose, and that services must be supplied within a reasonable time if there is no agreed time frame. Keep the certificate, the quote and the appliance paperwork together, since a future buyer's conveyancer will ask for exactly that file.

What drives the price of running a new gas line

  • The distance from the meter or the cylinder installation to the new point, which is the single biggest variable in most quotes.
  • The route and what it has to pass through: an accessible subfloor or roof space is straightforward, while a concrete slab, a finished wall or an underground run is not.
  • Whether the existing consumer piping can carry another appliance, or whether a section has to be upsized for the total connected load.
  • Whether the meter or supply itself needs upgrading, which involves the gas distributor as well as the gasfitter.
  • Natural gas or LP gas, since a cylinder installation brings its own siting, clearance and changeover requirements.
  • Reinstatement: making good plaster, flooring, paving or landscaping that had to be opened up to get the pipe through.
  • Appliance connection and commissioning, and the certification the state requires at the end of the work.

Gas Line Installation: frequently asked questions

Can I run my own gas line, or connect a barbecue point myself?

No. Gasfitting is licensed in every Australian state, and several make a point of there being no threshold: New South Wales requires a licence or certificate for any gasfitting work regardless of the cost of the work, and Queensland requires a licence or authorisation before any gas work at all, residential included. Energy Safe Victoria states that unlicensed gas work is illegal and potentially fatal. Connecting a portable barbecue to a cylinder with its own hose assembly is different from installing a fixed gas point, which is gasfitting.

What standard does gas pipework have to meet in Australia?

AS/NZS 5601. Energy Safe Victoria confirms AS/NZS 5601.1 and AS/NZS 5601.2 as the prescribed standards under regulation 14 of the Gas Safety (Gas Installation) Regulations 2018, with AS/NZS 5601.1:2022 the current general installations edition and gasfitters expected to comply in full with the 2022 edition from 30 March 2023. Amendments are automatically adopted under the regulations when published and become legally enforceable from that date.

What paperwork should I get after gas line work?

It depends on your state, so ask before the job. In Victoria the licensed gasfitter must give you a compliance certificate after installing a gas appliance, and Energy Safe Victoria warns that a cheap job excluding the certificate is an offence under the Building Act 1993. In Queensland the licence holder issues the owner or operator with an original copy of the gas system compliance certificate on completing an installation. In Western Australia, Notices of Completion are required under the Gas Standards (Gasfitting and Consumer Gas Installation) Regulations 1999.

Will my existing gas line handle another appliance?

Not automatically, and this is the check a good gasfitter makes before quoting. The pipe has to carry the total connected load, meaning everything that might run at once, so adding a cooktop to a line already feeding a heater and a hot water unit can leave all three underfed. The symptoms are burners dropping off when another appliance fires, poor heater performance on cold evenings, and sooting. Tell the gasfitter every gas appliance in the house, including any you plan to add.

Is LP gas treated differently from natural gas?

Yes. Appliances are built or converted for one or the other and are not interchangeable, the pressures differ, and cylinder installations bring their own siting and clearance requirements. AS/NZS 5601.1 covers general gas installations and a separate part deals with LP gas installations in caravans and boats. If you are moving between supply types, treat it as appliance work and pipework together, and have the gasfitter confirm every appliance is suited or converted.

How does LokalMatch work for gas line installation?

You post the job once, with your postcode, the appliance the line is for, whether the house is on natural gas or LP gas and roughly how far the new point is from the meter or cylinders, and licensed gasfitters covering your area get in touch with you themselves. Those businesses pay LokalMatch for the requests they receive. LokalMatch does not carry out gas work, does not set or quote prices, and does not vet, rank or recommend any business, so verifying the licence and confirming which certificate you will receive stays with you.

What affects the cost of gas line

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Type of system and fuel source
  • Size and efficiency of the equipment
  • Condition of the existing ductwork and venting
  • Electrical or gas line changes
  • Access to the furnace room, attic or outdoor unit location
  • Removal and disposal of the old equipment
  • Emergency or after-hours service

How to compare gas fitters before you hire

  • Hire a technician who is licensed for heating, cooling and gas work in your area.
  • For a new system, ask for a load calculation for your home rather than a size based on the old unit.
  • Get written quotes that list the equipment, ductwork changes, removal of the old unit and any electrical work.
  • Ask how they handle service calls and repairs after installation, including in the middle of winter.
  • Compare the full scope of each quote, not only the equipment on it.

Questions to ask gas fitters before you hire

  • Are you licensed for this type of heating, cooling or gas work in my area?
  • How did you decide what size of system my home needs?
  • Does this installation need a permit, and will you take care of it?
  • What does the manufacturer's warranty cover, and what does your labour warranty cover?
  • Will you need to change the ductwork, venting or electrical to make this work?
  • Do you offer maintenance plans, and what do they include?
  • How quickly can you respond if the system stops working?

When to call a pro for gas line

  • If you smell gas, leave the home and call your gas utility's emergency line from outside.
  • If a carbon monoxide alarm goes off, get everyone outside and call emergency services.
  • No heat in cold weather, or a furnace that keeps shutting off
  • Unusual noises, burning smells or a big jump in energy use

Gas line permits and local rules

Some gas line work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
