Gas Fitting Costs in NSW

Gas fitters charge $120 to $180 an hour across New South Wales, which sits roughly ten to twenty per cent above the equivalent general plumbing rates. The premium reflects the separate licence, the mandatory certification on every job and the consequences of getting gas work wrong. General plumbing rates appear at plumber prices. A licence to plumb does not automatically include a licence to fit gas. A gas leak makes a hazard where a water leak makes a mess.

Most gas jobs are quoted as a fixed price rather than hourly. Connecting a cooktop or a hot water unit is a defined piece of work with a predictable duration, so a fitter can quote it accurately, and hourly rates are generally reserved for fault finding and repairs. Ask for a fixed figure on any installation work. Hourly rates suit diagnostic and fault finding work only. A fixed price also removes any argument about how long a straightforward connection should have taken. Two appliances on one visit costs far less than two separate callouts.

A callout fee applies to almost every attendance and is usually built into the first hour. Getting a licensed fitter with a van of certified fittings to your address costs the same whether the job takes forty minutes or four hours. Combine several gas jobs into a single visit where you can. The saving on a second appliance is genuinely substantial. Two appliances connected on the same visit cost far less than the same two done a week apart. The callout charge lands once rather than twice over.

Appliance Installation

A gas cooktop connected to an existing point costs $200 to $400 and takes an hour or two. The work involves connecting the flexible gas line, testing every joint for leaks, checking the flame pattern across each individual burner and then issuing the compliance paperwork. Cooktop fitting sits at oven and cooktop installation costs. Checking the flame pattern is not a formality. Flame pattern tells a fitter whether the appliance is burning correctly on the gas supplied to it. A burner running yellow at commissioning gets adjusted before anybody leaves the site.

Gas ovens follow the same pattern at $200 to $400 for a straightforward connection. A combined cooktop and oven installation is slightly more economical than the two done separately, since the fitter is already on site with the testing equipment out. Book the cooktop and oven together wherever you can. The second appliance always costs less than the first. Flame pattern tells a fitter whether combustion is correct.

Freestanding cookers need more clearance consideration than built in units. The connection point, the position of the isolation valve and the clearances to adjacent cabinetry all have to work together, and a unit that will not sit flush against the wall usually has a reason behind it. Kitchen work is priced at kitchen plumbing costs. Measure the available space before the appliance arrives on site. Freestanding units also need the gas connection positioned so the appliance can be pulled forward for cleaning without stressing the hose. Testing equipment stays out across both appliances on a combined job.

Rangehood interaction matters more with gas than with electric. A powerful extraction fan in a tightly sealed kitchen can pull combustion products back down a flue in the wrong conditions, which is exactly why ventilation gets assessed alongside the appliance itself. Rangehood work appears at rangehood installation costs. A fitter assesses the whole room rather than just the connection. Modern kitchens are sealed far more tightly than older ones, which changes how much air is available for combustion. Combustion air supply forms part of that assessment.

Appliance certification is worth confirming before purchase. Gas appliances sold in Australia must be certified for use here, and an imported unit bought online may not be, which leaves a fitter unable to legally connect it. Check the certification marking before buying any gas appliance. An uncertified appliance simply cannot be legally connected. Certification marks appear on the appliance data plate rather than on the packaging. A fitter reads that data plate before connecting anything at all.

Disconnection and removal of an old appliance is a separate line. Capping off a redundant gas point properly, testing the cap and certifying it takes time, and leaving an uncapped point is not an option. Ask what happens to the old appliance and its gas point. Capping off a redundant point is a certified job in its own right. Modern kitchens seal tighter than older ones and change the air supply.

New Gas Points and Runs

Installing a gas point where none exists adds $300 to $800 to any appliance job. The figure covers the pipe run from an existing supply, all of the fittings, the isolation valve and the testing, and it varies mostly with how far the new point sits from the nearest usable connection. Distance from the existing supply drives the cost. Every metre of pipe and every bend in it adds time. A ten metre run through a subfloor and a three metre run through a finished wall can cost the same amount. An uncapped gas point is a live hazard behind a cabinet.

The route the pipe takes matters as much as the distance. A run through an accessible subfloor or roof space is straightforward, while one that has to cross a slab, penetrate a wall or navigate a finished ceiling becomes considerably more involved and slower. Walk the intended pipe route with the fitter. The obvious path is not always the available one. Concrete slabs are the hardest constraint, since a pipe cannot simply pass through one without core drilling or routing around. That detour around a slab frequently doubles the length of the run.

Copper and specialised gas piping are used rather than the materials common in water plumbing. Gas lines require particular joining methods, pressure testing before commissioning and specific identification marking, none of which is interchangeable with ordinary water work. The materials themselves are not the expensive part. The testing and the certification are what cost money. Pressure testing holds the line at a set pressure for a defined period to prove it is sound before gas ever enters it. That pressure test is what the compliance certificate attests to.

Kitchen renovations are the natural time to add gas points. A wall is already open, the floor is already up and the fitter can run pipe without cutting into any finished surfaces, which is precisely why doing it later costs several times more. Bathroom work is quoted at bathroom plumbing costs. Plan any gas points during the design stage of a renovation. Difficulty rather than pipe length is what actually gets priced.

Meter upgrades run $200 to $600 and become necessary when total appliance demand exceeds the existing meter's capacity. Adding a second cooktop, a heater and a gas hot water unit to a house sized for one appliance can trigger it. Ask whether the existing meter will cope with the load. The fitter calculates the total connected load. Meter capacity is expressed as a flow rate rather than a simple appliance count, and a fitter calculates the total demand across everything connected. Concrete slabs force a pipe to core drill or route around.

The network operator rather than the fitter controls the meter itself. Upgrading or relocating a meter involves an application to the distributor, their timeframe rather than yours, and sometimes their own charges on top. Energy matters are administered by NSW Energy. Allow several weeks rather than days for any meter work. Distributor timeframes for meter work run to several weeks in most of the state. Booking the fitter before the meter application is approved wastes everybody's time.

Bayonet fittings are the connection most households actually recognise. The socket in a wall or floor that a portable heater plugs into is a bayonet point, and installing one where none exists is the same $300 to $800 exercise as any other new gas point. Bayonet sockets need capping when not in use. The plug supplied with the heater is the cap. A missing cap leaves an open point behind the furniture.

Outdoor gas points for barbecues and patio heaters follow different rules again. An external point needs weatherproof fittings, protection from impact and a position that keeps the appliance clear of eaves and openings, and the run frequently passes through an external wall. Outdoor points cost toward the upper end of the range. Weatherproofing adds to the fitting cost. Timber decking complicates the route further.

Pool and spa heaters are the largest gas appliances most homes ever install. A pool heater draws considerably more gas than a cooktop and a hot water unit combined, which almost always triggers a supply line assessment and frequently a meter upgrade. Have the load calculated before buying the heater. The gas work can exceed the appliance cost. Undersized supply lines are the most common problem here.

Hot Water and Heaters

Connecting a gas hot water system costs $300 to $600 for the gas side of the job. That covers the supply connection, the isolation valve, pressure testing and certification, while the water connections and any tempering valve are separate plumbing work. System replacement is priced at hot water system costs. The gas connection is only one part of a larger job. The water side of a hot water installation is separate plumbing work with its own cost. Some quotes cover the gas side and not the water side.

Continuous flow units demand more gas than storage units do. A continuous flow heater fires at high output whenever hot water is drawn anywhere, which can require a larger supply line or a meter upgrade in a house originally set up for a storage system. Repairs are quoted at hot water repair costs. Confirm the existing supply can carry the additional load. Pressure testing proves a line is sound before gas enters it.

Flueing is the part of heater installation people underestimate. A flued appliance needs its flue run correctly, terminated in the right position relative to windows and boundaries, and sealed properly throughout, and none of that is negotiable. Flue requirements are prescriptive rather than advisory. Flue rules frequently dictate where a unit can physically go. Flue terminals have minimum distances from windows, doors, boundaries and anything above them. An open wall during a renovation is the whole cost difference.

Unflued gas heaters carry their own restrictions indoors. Combustion products enter the room directly with an unflued appliance, so room size, ventilation and the type of room all determine whether one can be used at all, and bedrooms and bathrooms are generally excluded outright. Never install an unflued gas heater in a bedroom. Ventilation requirements for unflued appliances are specific. Room volume relative to appliance output is the calculation that governs unflued heaters. A small tightly sealed room fails that calculation very quickly.

Space heater installation at $350 to $700 assumes an existing gas point nearby. Where the heater sits on an external wall well away from the current supply, the pipe run and the flue penetration together push the figure considerably higher again. Position the heater near the existing supply where possible. Placing a heater for convenience costs money here. A flue penetration through a wall or roof involves weatherproofing as well as the flue itself. The weatherproofing work adds cost beyond the gas connection itself.

Servicing existing appliances is worth budgeting annually. A gas heater accumulates dust in the combustion chamber, burners drift out of adjustment and flue seals degrade over time, all of which affect both efficiency and safety. An annual service costs a fraction of a replacement unit. An annual service also catches problems early. Meter capacity is a flow rate rather than an appliance count.

Leak Detection and Repair

Gas leak detection runs $150 to $350 and is charged as a diagnostic before any repair. A fitter pressure tests the whole system, isolates sections to narrow down the location and then uses electronic detection equipment where the leak is not obvious. Water leak work sits at water leak detection costs. The diagnosis and the repair are quoted as separate figures. Pressure testing isolates the system in sections so a fitter can narrow the leak to a length of pipe rather than searching the whole house. A dusty combustion chamber produces more carbon monoxide.

A gas smell is an emergency and should be treated as one. Turn off the supply at the meter, open windows and doors, avoid touching any electrical switch including a light switch, leave the building and call the network operator's emergency line before calling a fitter. Network emergency numbers are printed on the meter itself. The network operator's response is free and immediate. A phone or a torch switched on inside the building can provide the ignition source. Leaving the building first and calling from outside is the correct sequence.

The distributor attends emergencies at no charge but only makes the site safe. They will isolate the supply and confirm the leak, though the repair itself remains a licensed fitter's job and yours to arrange and pay for. Emergency plumbing is quoted at emergency plumber costs. Two separate attendances is entirely normal on a gas leak. The distributor's obligation ends at making the site safe rather than restoring your gas supply. Arranging and paying for the repair is entirely your responsibility.

Repair cost depends entirely on where the leak sits. A fitting at an appliance connection is a quick job, while a corroded section of buried line under a driveway means excavation, replacement and full reinstatement afterwards. Burst pipe work appears at burst pipe repair costs. The location of the leak is the whole variable. Sectional pressure testing narrows a leak to a length of pipe.

Older properties carry more risk in the gas lines. Steel pipe installed decades ago corrodes from the outside wherever it passes through soil or a damp subfloor, and a house that has never had its gas lines assessed may still be running on original material. Have older gas systems properly pressure tested. External corrosion stays invisible until the pipe fails. Steel gas pipe from before the 1980s is still in service in a great many older houses. Certification marking gets checked before any appliance is connected at all.

Carbon monoxide is the hazard people think about least. It has no smell at all, is produced by incomplete combustion in a poorly maintained or badly flued appliance, and an alarm costs very little measured against the risk. Health guidance is published by NSW Health. Fit a carbon monoxide alarm wherever gas appliances are used indoors. Carbon monoxide alarms cost thirty to eighty dollars and last several years. That cost is trivial against what an alarm actually detects.

LPG and Natural Gas

LPG and natural gas are not interchangeable and appliances are built for one or the other. The gas itself burns at a different pressure and requires different injectors entirely, so an appliance moved between the two needs conversion or replacement rather than simply reconnecting. Converting an appliance is certified work. It cannot be improvised on site. Injectors are sized for the pressure and calorific value of the specific gas. Running an appliance on the wrong gas produces either a starved flame or a genuinely dangerous one.

Converting a property from LPG to natural gas runs $1,500 to $4,000 for a typical residential job. That covers new connections, gas point modifications and appliance conversion or replacement, and the figure varies mostly with how many appliances are involved. More appliances in the house means more cost. Some appliances cannot be converted between gases at all. Individual isolation valves let one appliance be shut off independently.

Bottled LPG suits properties without a natural gas connection available. Much of regional New South Wales has no reticulated gas at all, which makes LPG the only option, and the running cost per unit of energy is generally higher. Compare the running cost per unit of energy before committing. Bottle exchange and delivery arrangements vary by supplier. LPG delivers more energy per unit volume but costs considerably more per unit of energy delivered.

Bottle installation carries its own siting requirements. Cylinders must sit in a ventilated position, clear of ignition sources and drains, with defined separation from openings and boundaries, and a fitter positions them accordingly. Cylinder siting follows fixed rules rather than preference. Those rules occasionally rule out the convenient spot entirely. Cylinders also need a firm level base and clear access for the delivery vehicle. Those two requirements rule out a surprising number of otherwise convenient positions.

Regulators and changeover valves are consumable items. A regulator has a service life, a changeover valve fails eventually, and both are cheap to replace against the consequence of a failure. Standards are published by Standards Australia. Have both checked during any routine service visit. A failed regulator can allow full cylinder pressure into an appliance designed for a fraction of it. Regulator replacement is inexpensive and well worth scheduling.

The natural gas connection itself is a network matter rather than a fitter's job. Where a main runs past the property, connecting to it involves an application to the distributor and their charges, which sit outside anything the fitter quotes. Ask what the network charges separately. Network charges do not appear in the fitting quote. Compliance paperwork is lodged with the regulator as well as handed over.

Licensing and Compliance

Gas fitting requires a specific licence endorsement beyond a general plumbing licence. A tradesperson can hold a plumbing licence and be legally unable to touch a gas appliance, which is why checking the endorsement rather than the licence matters. Licensing is administered by NSW Fair Trading. A public register makes that check straightforward. Fair Trading maintains a public register where a licence and its endorsements can be checked in a minute. Pipe routes through finished ceilings cost far more than open subfloors do.

A certificate of compliance is mandatory on every completed gas job. The fitter issues it, lodges it where required and provides you a copy, and that document is the evidence that the work was done to standard by somebody entitled to do it. Receive the certificate rather than requesting it. A fitter offering to skip the certificate is a warning sign. A certificate issued but never handed over is a common enough occurrence to be worth asking about explicitly.

The certificate matters well beyond the day of the work. A conveyancer may ask for it at sale, a managing agent may want it for a rental property, and an insurer assessing a gas related claim will certainly ask whether the work was certified. Keep gas certificates with the property documents. The certificate is worth more than the receipt. Conveyancers increasingly ask for gas certification alongside electrical and pool compliance. Having the file already assembled saves a scramble at exchange time.

Unlicensed gas work carries consequences beyond a penalty. Insurance cover can be affected where uncertified work contributed to an incident, and the exposure sits with the property owner who arranged it rather than with whoever did it. Never accept unlicensed gas work at any price. The saving is trivial measured against the risk. Continuous flow units frequently decide whether a meter needs upgrading.

Public liability cover should be verified as with any trade. Ten million dollars is the reasonable expectation, and a certificate of currency takes moments to produce for anybody who holds one. Workplace safety is administered by SafeWork NSW. Check the expiry date while you have it. Certificates of currency lapse annually and a policy expiring next month is worth knowing about. Flue terminals cannot sit under a window or hard against a boundary.

Rental properties carry additional obligations on the landlord. Gas appliances in a tenanted property need to be safe and maintained, and the certification trail matters more where somebody else lives in the house. Plumbing services generally appear at plumbing services costs. Keep the certification records on the tenancy file. Landlord obligations around appliance safety are separate from the general repair obligation. The certification trail is what actually demonstrates compliance.

Gas Safety at Home

Knowing where the gas isolation valve sits is the most useful thing a householder can do. Every property has a main isolation point at the meter, and being able to shut it off quickly matters more in an emergency than any other piece of knowledge. Locate the isolation valve before you ever need it. Show everybody in the household where it sits. The main isolation valve is at the meter and turns ninety degrees to shut off.

Individual appliance isolation valves let you shut off one unit without the whole house. A valve behind the cooktop or beside the heater means a faulty appliance can be isolated while the hot water keeps running, which is worth having fitted. Ask about appliance isolation during any job. They cost little when the fitter is already there. Unflued heaters are excluded from bedrooms and bathrooms entirely.

Flame colour tells you something worth noticing. A gas flame should burn blue with a defined shape, and a yellow or orange lazy flame indicates incomplete combustion, which means the appliance needs attention rather than continued use. A yellow flame is a service call rather than a quirk. Yellow flames also produce carbon monoxide. Blue flames with defined cones indicate complete combustion at the correct air to gas ratio. Annual servicing keeps the burners adjusted and the seals intact.

Ventilation matters more than people assume with gas appliances. Sealing a house tightly for efficiency reduces the air available for combustion, and modern homes with good sealing sometimes need dedicated ventilation for an appliance that would have been fine decades ago. Never block an existing fixed vent. Fixed vents are there for a specific reason. Fixed vents in older homes were installed deliberately to supply combustion air. Sealing those vents during a renovation creates a problem nobody intended.

Flexible connection hoses have a service life and get overlooked. The hose behind a cooktop or oven perishes over years of heat exposure, and replacement is inexpensive against the consequence of failure. Replace hoses at the service interval. Check the hoses whenever an appliance is moved. Flexible hoses carry a manufacture date and a recommended replacement interval. Most people have never looked at either of those markings.

Annual appliance servicing is the practical answer to most of the above. A fitter checking burners, flues, seals and connections once a year catches deterioration before it becomes a fault, and the visit costs less than most single repairs. Book appliance servicing well before winter. Heater servicing demand peaks through autumn. Network operators attend gas emergencies at no charge to the household.

Sydney Metro Costs

Sydney rates sit at the top of the state range, driven by wages, travel across a congested city and the cost of running a licensed business in the metropolitan area. The market is deep enough that comparing three quotes is straightforward. What varies most across the city is the housing stock, since a terrace with original steel gas lines and a new apartment with a modern reticulated system present completely different jobs. Sydney fitters commonly book three to seven days out in normal conditions. Emergency attendance is available at a significant premium.

Older inner suburban housing carries the most gas line risk in the city. Terraces and cottages with original steel pipe running through damp subfloor space are where corrosion problems concentrate, and a leak in that material usually means replacing a section rather than a fitting. Have older lines assessed before adding appliances. Existing pipework may not carry more load. Steel pipe in a damp subfloor corrodes from the outside inward, which means the wall thickness reduces invisibly. Older houses frequently still run on their original steel gas pipe.

Apartment gas work brings building constraints that houses do not have. Access to the meter, common property considerations, restricted working hours and sometimes building approval for contractors all apply, and none of it relates to the gas itself. Access arrangements take longer to organise than the work itself. Strata buildings need real lead time to arrange access. Building managers frequently require a certificate of currency on file before granting access. Arranging that certificate takes a day or two rather than an hour.

Newer estates through the growth corridors are the most straightforward work available. Modern reticulated systems, accessible pipe routes, meters sized for current appliance loads and no legacy material make for predictable jobs. Prices in those areas sit at the lower end. Estimating on those properties is also more reliable. Modern estates were built with appliance loads in mind rather than retrofitted around them. That forward planning shows in how straightforward the work turns out.

Regional NSW Costs

Regional rates run below Sydney, though travel narrows the gap and availability rather than price is frequently the constraint. Licensed gas fitters are fewer outside the major centres, and a fitter covering several towns builds the drive into the quote. Ask which day they cover your area. Fitting an existing run helps considerably. Carbon monoxide gives no smell and no warning of any kind.

LPG dominates across much of regional New South Wales. Where no reticulated main runs past the property, bottled gas is the only option, which changes the appliance selection, the siting requirements and the running cost calculation entirely. Expect LPG rather than natural gas inland. Appliances differ between LPG and natural gas. LPG appliances and natural gas appliances look identical on a showroom floor.

Travel is charged more openly outside the metropolitan area. A fitter driving forty minutes each way to a rural property is spending most of a morning on one job, and that time appears somewhere in the figure. Establish how travel time is handled on a regional job. Rural attendance frequently carries a component. Forty minutes each way turns a one hour job into most of a morning. Regional fitters are generally straightforward about how travel gets charged.

Winter demand spikes sharply in the colder districts. Heater faults concentrate in the first cold snap of the season across the tablelands and the central west, and availability tightens accordingly for several weeks. Book heater servicing through autumn instead. The first cold week is the worst time to need somebody. The first genuinely cold week of the year generates more heater callouts than the rest of winter combined. Everybody discovers their heater fault in the same week.

Emergency response times stretch in regional areas. The network operator attends gas emergencies across the state, though a licensed fitter for the subsequent repair may take longer to reach a remote property. Drainage work is quoted at blocked drain plumber costs. Plan around that where you can. Insurers routinely ask about certification when assessing any gas claim.

Strata properties add a layer that houses do not have. The meter may sit in a common property cupboard, access needs arranging through the building manager, and works affecting anything beyond your own lot can require owners corporation consent. Confirm what the scheme requires before booking a fitter. A tradesperson turned away at the lobby has still lost the morning. Contractor registration is common in larger buildings.

Insurance work follows its own sequence and it pays to understand it. Where an insurer is involved after an appliance fault or a gas related incident, the assessor generally needs to inspect before repairs proceed, and work carried out beforehand can complicate the claim. Photograph everything and call the insurer first. Emergency make safe work is treated differently from repairs. Keep every certificate and invoice together.

Quotes that look unusually cheap usually exclude something specific. The compliance certificate, the isolation valve, capping an old point or the testing itself are the items that quietly disappear from a low figure, and none of them are optional. Ask a cheap quote what has been left out. The answer is generally the certificate. Comparing quotes means comparing scope rather than headline price.

Running Costs and Efficiency

Efficiency ratings on gas appliances translate directly into running cost over a season. A star rating reflects how much of the gas burned actually becomes useful heat, and the difference between a low and high rated heater across a winter is substantial rather than marginal. Check the rating before purchase rather than after installation. The cheaper unit frequently costs more to run. Energy labelling appears on the appliance data plate alongside the certification. Autumn is the sensible time of year to book heater servicing.

Continuous flow hot water is more efficient than storage on paper and not always in practice. A storage unit loses heat continuously through the tank wall, while a continuous flow unit only fires when hot water is drawn, though short frequent draws waste gas in ignition cycles. Usage pattern decides which suits a household. A large family draws differently from a couple.

Appliance age matters more than most people assume. A twenty year old gas heater burns considerably more gas for the same output than a current model, and the difference across a decade of winters can exceed the replacement cost. Compare running cost against replacement cost honestly. Old appliances also fail at the worst moment.

Servicing keeps an appliance near its rated efficiency. Burners drift out of adjustment, combustion chambers accumulate dust and flue seals degrade, and each of those reduces the heat produced per unit of gas consumed. An annual service pays for part of itself in gas. It also extends the appliance life.

Electrification is worth considering before committing to new gas infrastructure. Where a property is adding gas points and upgrading a meter for a new appliance, the total cost of that gas work against an electric alternative is a calculation worth running properly. Compare the total installed cost of both. New gas runs are the expensive part of the decision.

What to Look Out For

Check the gas endorsement rather than the licence number. Gas fitting requires a specific endorsement beyond a general plumbing licence, and a tradesperson can hold a valid plumbing licence while being legally unable to touch a gas appliance. Verify it before anybody starts work, along with public liability cover and a current certificate of currency. Unlicensed gas work carries consequences well beyond a penalty, since insurance cover can be affected where uncertified work contributed to an incident, and that exposure sits with the property owner who arranged the work.

Insist on receiving the compliance certificate. Every completed gas job in New South Wales requires one, the fitter issues it, and you should receive a copy rather than have to chase it. That document is evidence the work was done to standard by somebody entitled to do it, and it matters at sale, at a rental inspection and at claim time. Anybody who suggests the certificate is optional or offers a discount for skipping it is telling you exactly what kind of operator they are.

Establish whether a gas point already exists. Connecting an appliance to an existing point is $200 to $400, while running a new line adds $300 to $800 and turns a one hour job into most of a day. The route matters as much as the distance, since a run through an accessible subfloor is straightforward while crossing a slab or navigating a finished ceiling is not. Walk the route with the fitter before accepting a figure, and ask whether the meter will carry the additional load.

Treat a gas smell as an emergency rather than a service call. Their attendance is free and immediate, though they only make the site safe and the repair remains a licensed fitter's job to arrange. Never attempt to locate a gas leak yourself, and never use a flame or a phone inside the building to do it. Confirm the position before anybody starts any work.

Confirm the appliance is certified for Australian use before you buy it. The same applies to moving an appliance between LPG and natural gas, since the two burn at different pressures and need different injectors, so conversion is a certified job and some units cannot be converted at all. Endorsements are listed separately on the licence record. The paperwork is what proves the work was done properly.

What to Look for in a Quote in NSW

A gas fitting quote should state the licence number and gas endorsement, confirm public liability cover, and say plainly whether the compliance certificate is included in the price rather than added afterwards. It should identify each appliance separately, state whether an existing gas point is being used or a new run is required, and set out the pipe run length and route where new work is involved. Any meter upgrade, network charge or after hours loading belongs on the document rather than arriving later. The gas point question and the certificate are the two items most likely to change a final invoice.

Give every fitter the same information. The appliance make and model, whether a gas point exists and where, the distance from the meter, the age of the house and whether the system is natural gas or LPG all shape what should be proposed. Send each of them the identical brief. Photographs of the meter and the intended location help considerably.

Ask what they would check before connecting. A fitter who mentions testing the existing lines, confirming the meter capacity or assessing ventilation is thinking about the whole system rather than the single connection in front of them. Listen for the system level answer. It usually indicates the more thorough operator.

Settle the licence, the certificate, the gas point and the appliance before anybody starts. Verify the endorsement, confirm the certificate is priced in, establish whether a new run is needed and check the appliance is certified for Australian use. Related work is priced at gas fitting services and at backflow prevention costs, with inspections at drain camera inspection costs. With those four settled, the job proceeds and the paperwork follows it.
