Appliances connected and certified, leaks made safe. And where a new run is involved, a route walked before a figure is given, because on this ground the trench is most of the job.

Connecting an appliance to a point that already exists is straightforward work anywhere. Where gas gets expensive is a new run, because a new run means a trench.
On flat, workable ground a trench is largely a question of length. Here it is not. Prospect sits over Sydney's largest body of igneous rock, quarried for road base precisely because it is hard, with heavy clay above it that is difficult when wet and close to concrete when dry.
So the same warning applies to a gas run as to any excavation in this suburb: a price quoted on metres alone is an estimate. What decides the cost is the route and how deep the easy material goes along it.
It also means the shortest line is frequently not the cheapest. Around a driveway rather than under it, along an existing service trench, or a slightly longer path through softer ground can all come out ahead, and that is only knowable by walking it.
No switches, no power points, no phone indoors. Open what you pass on the way out, turn it off at the meter if you safely can, then ring us from outside.
No ground involved at all, so it costs what it costs anywhere and there is no uncertainty in it.
Worth asking first whether a point already exists near where you want one, because sometimes one does.
Prospect sits over Sydney's largest igneous intrusion, with heavy clay above it. Neither is easy digging.
So the excavation is the substantial part of the job rather than a preliminary to it.
Length is not the variable here. Depth to workable material along the route is, and it changes across a property.
A good quote states its assumption and what happens if rock is met earlier. Ask for that before you agree rather than after.
Around a driveway instead of under it, along an existing service trench, or a longer path through softer ground can all come out ahead.
That is only knowable by walking the route, which is why we do that before quoting rather than pricing off a plan.
Heavy clay shrinks and swells with moisture, so a buried line here experiences movement it would not in stable ground.
Not a reason for alarm, and modern materials cope. It is a reason to take any smell near the run seriously rather than assuming it is nothing.
Get air through the building and get people out of it. Leave every switch, fan and appliance exactly as it is on the way past.
If the meter is accessible without going towards the smell, turn it off there. Otherwise it waits.
Ring from outside the building. A faint smell near one appliance that clears with a window open is a report. A strong smell you can follow is the version where nobody goes back in.
A quote for a new gas run should say where the pipe is going, not only what it costs. On this ground the route is the job and two routes to the same appliance can differ by thousands.
It should also say what happens if rock is met shallower than assumed, with a rate rather than a shrug. That is the honest way to price uncertainty.
If a quote does neither, it has not been thought about, and the variation will arrive later.
Where a service trench already exists and can lawfully be shared or run alongside, the hard part of the work has been done once already.
It is not always possible and there are separation requirements between services that have to be met. But it is worth asking about rather than assuming a fresh trench.
Anybody who has worked on the property before may know where those runs are, and so may your own records.
Adding an appliance is a calculation against total demand rather than a connection. The line has a capacity and so does the meter, and a new appliance has to fit inside both with the existing ones running.
Where it does not, appliances starve each other. A burner that drops off whenever somebody runs a shower is nearly always this.
Doing the sums first is most of the difference between an installation that works and a callback.
Gas pressure falls along a run, and the drop grows with length and with load. A long run to a large appliance needs a bigger bore than a short one to a small appliance.
Which means a longer route around an obstacle is not simply more metres. It may need a larger pipe as well, and that belongs in the comparison.
It is a calculation rather than a judgement, and it happens before anything is dug.
The pipe is sized for how far it runs and how much it has to carry. The line is tested to pressure. The appliance goes in to its own instructions with the clearances they specify. The flue discharges where the standard says.
By the time you are cooking on it, all of that is inside a wall or behind a cupboard.
So the paperwork is not administrative overhead. It is the only surviving record of work you cannot go back and look at.
Every gas job finishes with a compliance certificate recording who did the work, that they held a licence, and that the installation met the standard on the day.
Keep it with the property papers. It is what an insurer asks for after an incident and what a conveyancer eventually asks for at sale.
On a buried run it is also the only evidence of where the pipe actually went, which matters the next time anybody digs.
Agreed before we start. These are indicative 2026 ranges. The Certificate of Compliance is included on every gas job and is never charged as an extra.
Any hour. Isolated and made safe first, then diagnosed properly.
Onto an existing point, tested and certified. No ground involved, no uncertainty.
Where it lands depends on the route and the ground far more than on the distance.
Walked and planned before you commit, with the ground assumption stated.
On every gas job. Legally required, and never charged for here.
On any suspected leak the supply is isolated first, and diagnosis follows once the property is safe.
For new work, before anything is priced. The cheapest run is the one that turns out not to be needed.
With the ground assumption stated and what changes if rock is met shallower than expected.
Tested again on completion and your Certificate of Compliance issued on the spot.
Get everyone outside, avoid anything that could spark, and ring us from outdoors. A licensed gas fitter answers at any hour and we treat it as urgent.
Call 1300 381 569Stop reading and act. Do not touch a light switch, a power point or anything that could spark, and do not use a phone inside the building. Open doors and windows on the way out, turn the gas off at the meter if you can safely reach it, get everyone outside, and ring from outdoors. We answer 24 hours and treat it as the highest priority job we take.
Because most of a new run is a trench, and this is not easy ground to trench. Prospect sits over Sydney's largest body of igneous rock, and the material is quarried for road base precisely because it is hard. Add heavy clay above it, which is difficult in its own way when wet and close to concrete when dry, and the digging becomes the substantial part of the job rather than an afterthought.
With the route walked and the ground discussed, not on metres alone. The same warning applies here as to drainage excavation: a price given on length is an estimate until somebody has thought about depth and what is under the line. A good quote states what it assumes and what changes if rock is met shallower. Ask for that before agreeing, because afterwards you have a half-finished trench and no leverage.
Frequently, and it is worth asking. Going around a driveway rather than under it, following an existing service trench, or taking a slightly longer path through softer ground can all cost less than the short direct route. On flat sedimentary ground the shortest line is usually cheapest. Here it often is not, and a fitter who has walked the route will know which applies.
It can, and it is worth understanding. Heavy clay shrinks and swells with moisture, so a buried service laid in it experiences movement that a line in stable ground does not. That is not a reason for alarm, and modern materials handle it, but it is a reason to take any smell near the line seriously rather than assuming it will be nothing.
Very often, yes, and that is the cheap version of this trade. Connecting an appliance to a point that already exists is straightforward work with no ground involved at all. The costs here are entirely about new runs. So the first question worth asking is whether the point you need already exists somewhere near where you want it.
A leak test and make-safe is $200 to $450. Connecting an appliance to an existing point is $250 to $550, with no excavation involved. A new gas point or run is $450 to $1,200, and on this ground where it lands in that range depends on the route far more than the distance. The compliance certificate is included on every gas job.
Tell us what you want connected and roughly where it needs to end up. If there is already a point nearby, this may be a much smaller job than you are expecting.
Existing points checked first, the route walked before pricing, and a Certificate of Compliance before we leave.
