Gas line installation cost can be confusing because many guides give a single flat rate with no job context. That’s why you see one quote for $250 and another for $5,000.
The reason? Completely different job scopes. Pipe distance, layout, appliance type, and whether it’s a hookup or full new gas connection all change the price.
This article breaks down costs by job type, so you know exactly what you are being quoted for. Keep reading!
The first thing to check is the type of gas line job you need. That has the biggest say in the price. Here’s how Melbourne metro prices usually break down. All figures include GST.
| Job Type | Low | High |
|---|---|---|
| Gas cooktop installation & single appliance connections | $160 | $470 |
| Gas bayonet / outlet installation | $160 | $420 |
| Gas line extension (existing connection, new room or appliance) | $300 | $700+ |
| Outdoor BBQ gas point installation | $210 | $630 |
| Gas hot water system installation (connection labour) | $210 | $630 |
| Gas heater installation (flued) | $315 | $945 |
| New gas line run (meter to appliance, no existing line) | $525 | $2,100 |
| Gas meter relocation | $630 | $2,625 |
| New mains gas connection (distributor fee + gas fitter) | $2,200 | $6,000+ |
| LPG to natural gas conversion | $420 | $1,575 |
| Compliance certificate | $84 | $160 |
Note that these are Melbourne metro ranges. Outer suburbs like Pakenham and Cranbourne often sit at or above the high end due to travel time.
And the final costs depend on pipe length, wall type, access, and the number of gas appliances.
Short runs through timber-frame walls are cheaper, while longer runs through brick, under slabs, or via ceiling cavities can push the price up fast
Two quotes for the same job can be $800 apart. Here’s what’s actually driving that gap:

Most Melbourne gas fitters charge in one of two ways: hourly rate or fixed job price.
For an hourly rate, expect to pay $105–$210 per hour, plus a call-out fee. Choose this if the job is tricky to define upfront.
For example, if you are tracking a leak in old pipes, checking a hidden gas line, or figuring out why your current supply will not support a new appliance.
You might not know the final cost until the fitter tests your system or opens up the area.
Fixed job price is more common for standard work, such as a cooktop connection, a new BBQ point, or a short gas line extension where the route and access are clear.
It is easier to budget for because you know the price before work begins.
Keep in mind, always get a written quote before the job starts. Ask whether it includes GST, materials, the call-out fee, pressure testing, commissioning, and the required compliance certificate.
For clearly scoped work, a reputable gas fitter should be able to explain the fixed price, or they should clearly tell you why hourly billing makes more sense.
Melbourne Gas Plumber offers upfront pricing with no hidden costs, and same-day standard-hours service.
Remember, after-hours, weekend, and emergency call-outs usually cost more than standard-hours work, so confirm the surcharge when you book.

First, check if you have mains gas at your property.
Not every property in Melbourne is connected to the natural gas network. Before you buy a new cooktop or heater, check if there’s a gas main running past your address.
Melbourne’s gas network is split between three distributors:

Don’t guess based only on the suburb name. Some areas overlap or sit near distributor boundaries. To be sure, just enter your address on their website or give them a call.
And if your street doesn’t have a gas main? Well, then you can’t get a standard connection. Your next best option is usually LPG (which we’ll cover in the next section).
A new mains gas connection has two separate cost components. This is where many homeowners underestimate the budget.
The first cost is the distributor connection fee. This is paid to the gas network operator to connect the service line from the street main to your property and install the meter.
For 2026, current standard/basic residential connection fees are:
| Distributor | 2026 Standard/Basic Connection Fee |
|---|---|
| AusNet Services | $1,960 ex GST |
| Australian Gas Networks | $2,157 ex GST |
| Multinet Gas / MGN | $2,660 ex GST |
Distributors charge this rate for basic residential connections where gas mains already reach your property.
The second cost is the licensed gas fitter’s fee.
Costs depend on pipe length, access, appliance count, and pipe size, as well as any necessary modifications to existing lines. The jobs range from $800 to $3,000.
You need both parts, usually billed separately. The distributor connects the street main to your meter, while your licensed gas fitter Melbourne manages pipes from the meter to your appliances.
So if your property is eligible and the gas main is already available, a realistic Melbourne budget is often around $2,460–$4,660 before GST.
If you lack a street gas main, LPG is the alternative. What’s the main difference? LPG is cheaper to set up for small jobs, but natural gas costs less to run long-term.
For LPG, a basic setup costs about $300–$700 if the provider gives you the cylinder. If you already have the pipes and a regulator, a 45kg bottle hookup might cost even less.
Conversely, natural gas installation costs depend on whether your property is already connected, but it removes the hassle of cylinder refills, rentals, and supply contracts.

If you don’t use much gas, LPG is your best bet. If you use a lot for things like hot water and multiple appliances, natural gas will save you more money.
Please remember, most Australian appliances run on either gas type, so you might need a conversion kit. Check your fuel type before you order, and make sure a licensed gas fitter handles the installation.

You already know the gas pipeline installation cost. Now, you’re probably wondering who installs gas lines.
Only a licensed gas fitter can legally install, extend or connect gas pipes and appliances. This is required by AS/NZS 5601.1:2022 and enforced by Energy Safe Victoria and the Victorian Building Authority.
Doing your own gas work? Don’t. It’s illegal and will void your home insurance. Both matter, and this is not the kind of job to test yourself on.
It doesn’t stop there. For a standard home job on a building with five storeys or fewer, your gas fitter must submit a Compliance Certificate to the Victorian Building Authority within five business days.
Keep that certificate. It’s your legal proof that the installation was completed properly. You may need it for insurance, a future property sale or if there is ever a dispute about the work.
And please note that some jobs follow a different process. For complex installations, like new gas risers in multi-storey buildings, you’ll need Energy Safe Victoria’s approval before you start.
So, before you book, check the gas fitter’s licence. The VBA keeps a public licence register at vba.vic.gov.au, and a licensed gas fitter should be happy to give you their licence number.
These are some questions relevant to gas line installation costs in Melbourne.
How much does it cost to run a gas line to a new appliance in Melbourne?
For Melbourne homes with natural gas, connecting one appliance costs $160–$470. Extensions range from $300–$700, while new lines from the meter cost $700–$2,500. Costs rise for complex installations.
Is it cheaper to connect to mains gas or use LPG?
LPG costs $650–$1,500 upfront, compared to $2,460–$4,660 for mains gas. However, natural gas is cheaper long-term for high-volume users. Mains gas suits Melbourne homes with multiple appliances, while LPG is better for single outdoor units without mains access.
Does the gas fitter fee include the Certificate of Compliance?
Yes. Always confirm quotes first, as reputable tradespeople include this in their price. Also, a mandatory Certificate of Compliance must be lodged with the VBA within five days of completion. No worries, Melbourne Gas Plumber provides this with every installation for your protection.
How long does gas line installation take?
Standard residential appliance connections take 1–2 hours. New gas service fitting takes half a day to a full day, plus weeks for meter installation. Budget 4–8 weeks for full grid connections.
Can I get gas installed if my house is all-electric?
If your home is near a gas main, you only need a distributor connection and a gas fitter. However, mains gas is not available for new buildings with permits filed after January 2024.
Gas line installation costs in Melbourne range from $160 for simple connections to over $6,000 for full mains setups. The final price depends on the job, how much piping you need, and your distributor’s requirements.
