How much do gas fitting services cost? It depends on the job, but on four recent Perth jobs, prices ranged from $421.30 for a gas leak test and make-safe to $5,925.70 for tracking down and repairing a buried gas leak on a school site. Installations sat in between, with a gas bayonet for a heater at $1,334.30 and a kitchen renovation gas package at $2,721.40.
Gas work is different from the rest of plumbing for one simple reason: getting it wrong is dangerous. Every job on this page was done by a licensed gas fitter, tested before and after, and that discipline is built into the price. What you pay comes down to how much testing the job needs, the compliance requirements that come with it, such as ventilation, isolation valves and correct connections, and how hard the problem is to find.
Read on to see what each of the four jobs involved, what it cost and why, so you know what to expect before you book. They’re priced at our current rates, and prices include GST.

1. The Gas Smell in a Just-Purchased Home in Ellenbrook
What happened
New owners moved in and could smell gas near the cooktop. Nobody wants that in week one of a new house. Natural gas has no smell of its own, so an odour is added to it precisely so that leaks get noticed, which means a smell near an appliance should always be taken seriously. Because the home had only just changed hands, the owners had no way of knowing how the gas appliances had been installed, so the whole system needed checking, not just the cooktop.
What it cost
$421.30
Why it cost that
We ran a full gas leak test on the property and found two problems. The cooktop had been installed without the required 90-degree elbow, connected straight onto the flexible hose, a non-compliant installation, which means the house was sold with a gas leak built in. The test also showed four loose brass flare nuts at the back of the property, which we tightened until the test held. We capped off the cooktop supply so the rest of the house could keep using gas safely while the correct parts came in, and quoted the compliant fix. That’s what a gas call-out buys: the whole system tested, the real cause found, and the house left safe that day.
2. A Gas Bayonet for the Heater in Meadow Springs
What the job was
The customer wanted an internal gas bayonet point so they could run a gas heater. A bayonet is a wall outlet that a portable gas heater connects to, giving a room a gas supply without a fixed appliance. Because the heater burns gas inside the home, the installation has to meet gas safety standards from the supply line outside right through to the room itself.
What it cost
$1,334.30
Why it cost that
A bayonet looks like a simple socket on the wall, but the socket is the small part of the job. We tested the property for leaks before starting, drilled through and fitted the bayonet, ran and connected the gas pipework outside, and installed the high and low level room vents that a gas heater legally requires, one of them through double brick. Then the system was tested and commissioned. The ventilation is what people don’t expect on the quote, and it’s not optional: it’s what makes a gas heater in that room safe and compliant.
3. A Kitchen Renovation Gas Package in Safety Bay
What the job was
A kitchen renovation needing the gas centrepiece sorted: a new free-standing gas oven, with the dishwasher, fridge water line and sink connections done in the same visit. Renovations often run to a tight timeline with several trades involved, and a new kitchen isn’t usable until every appliance is connected, tested and safe. Only a licensed gas fitter can connect a gas appliance, so this part of the job couldn’t be left to the cabinet maker or a handyman.
What it cost
$2,721.40
Why it cost that
The gas work leads the price: testing the existing pipework for leaks, new gas isolation valves and flexible hose, and the oven installed to the manufacturer’s spec, then tested and commissioned. While we were there, the customer’s dishwasher went in with a combination valve, the fridge water line came down from the roof space with a filter, and the sink and tap were connected. One licensed crew, one visit, the whole kitchen live at the end of it, and every connection tested before we left.
4. Tracking a Gas Leak Across a School Site in Leederville
What happened
Staff at a school could smell gas in two different areas. On a commercial site with multiple buildings and long buried gas runs, “there’s a smell somewhere” is a genuine detective job. Gas escaping underground can travel along the soil and surface some distance from the actual leak, so where people notice the smell isn’t always where the fault is. With students and staff on site every day, finding the source safely and without guesswork was the priority.
What it cost
$5,925.70
Why it cost that
This is methodical work. We tested the science block: held pressure, no leak. Tested at the meter near home economics: pressure drop, leak confirmed. We isolated sections to narrow it down, dug up and exposed the connection into the building, and located the leak at an 80mm adaptor on the buried line. The leaking section was cut out and replaced with new copper and fittings. Follow-up testing then showed the old line was still losing pressure elsewhere, so rather than sell the school an endless series of digs, we recommended and quoted a full re-run of the line from the meter to the building. On ageing buried gas lines, that’s the honest answer: fix what’s found, test again, and when the line itself is the problem, say so.

FAQ
It depends on the job. In the examples above, a leak investigation that found and made the problem safe cost $421.30. Installing a gas heater bayonet with the required vents cost $1,334.30, and a kitchen gas package was $2,721.40. Tracking a leak across a school's buried gas lines came to $5,925.70.
A gas heater legally requires high and low level ventilation in the room. It's the part of the job people don't expect on the quote, but it's not optional: the vents are what make a gas heater in that room safe and compliant.
We test the whole system to find the real cause, not just the first problem. At Ellenbrook, we found a non-compliant cooktop connection and four loose fittings. We tightened the fittings, capped off the cooktop supply so the rest of the house could keep using gas safely, and quoted the compliant fix. The house was left safe that day.
Commercial sites often have multiple buildings and long buried gas runs, so finding a leak takes method: test, isolate sections, prove where the leak is, fix it and test again. At a Leederville school, that meant digging up a buried line to reach the leak. When an old line keeps losing pressure, we'll tell you if a full re-run is the better fix.
Yes. At Safety Bay, the new gas oven went in during the same visit as the dishwasher, fridge water line and sink connections. One licensed crew, one visit, and every connection tested before we left.
