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.
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.

Stop 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.
