All that wood smoke and dust in your home might make you think about a clean‑burning gas setup. You’re ready for a new gas installation, but the real question hits: what’s the cost to convert a fireplace to gas?
You’ve come to the right place. We’ll break down the real costs and options that fit your budget, so you can make a switch with confidence. Read on!
The cost to convert a fireplace to gas in Melbourne ranges from $1,500 to $10,000. Most homeowners pay $4,000–$7,000 for a standard project involving a vented gas insert, minor flue work, and a short gas line run.
Here’s how the cost to convert a fireplace to gas realistically breaks down:
| Tier | What’s Involved | Cost |
|---|---|---|
| Low | Gas log set, existing line nearby, serviceable flue | $1,500–$3,000 |
| Mid | Gas insert, minor flue work, short gas line run | $4,000–$7,000 |
| High | Direct-vent system, new gas line, flue or structural repairs | $7,000–$10,000+ |
And that cost really depends on how much work the gas fitter has to do:
Remember, if your home has no gas line near the fireplace, that alone adds $1,200–$5,000 before any fireplace work. But, these are all estimates. A licensed gasfitter’s inspection is needed for an accurate quote.
What about the $300 or $500 you see online? Well, they’re almost never for a full fireplace conversion. They usually leave out the unit, the gas line extension, the labour, and compliance.

Knowing the cost tiers is the start. Understanding what drives the price up or down helps you plan better:
The conversion type is usually the single biggest variable in your quote.
A gas log set is the simplest option. A burner and decorative logs go inside your existing open firebox and connect to your gas supply. It’s mostly about look and ambience, not heating efficiency.
It suits homeowners who want a fire’s look without ash and a woodpile. The installation takes 2–4 hours and it costs around $1,500–$3,500 installed.
A gas insert is a sealed metal box that fits into your current fireplace and has a lining up the chimney. It’s more efficient because the closed chamber sends heat into the room instead of losing it up the chimney.
This option needs small changes to the flue system, and that’s what makes the installation take 4–8 hours with a cost of about $4,000–$7,500 installed.
A direct-vent system is the most complex. It takes air for burning from outside and sends exhaust out through its own pipe.
This option is good for older homes with blocked or damaged flues. Installing it means cutting through an external brick or weatherboard wall. It can take 6–10 hours and the estimated cost is $6,000–$10,000 to install.
This is the biggest hidden cost. If your fireplace is in the lounge and your gas meter is 15 metres away at the front of the house, you’re paying for pipe, fittings, labour, and wall access.
Running a new pipe from your gas meter to the fireplace is skilled work that takes time. Gas line installation costs in Melbourne:
Without an existing gas connection near the fireplace, expect to add $1,500–$3,000 to your quote. This is why it’s critical to mention gas line access when you call for a site inspection.
Your chimney may look fine on the outside, but inside it could be cracked, blocked, or covered with years of creosote. These problems cause the most unexpected costs when converting a fireplace to gas.
Fixing the flue pipe costs $800–$3,500 depending on how bad it is. A new stainless steel liner costs $2,500–$5,000, while chimney cleaning and inspection costs $200–$400.
It’s far better to know the scope before you commit than to find structural issues midway through the job.
Licensed gas fitters typically charge $120-$180 per hour. Standard fireplace conversions usually take 4-8 hours. Complex jobs like adding new gas piping and wiring an ignition system can take longer.
If your job needs electrical work, like for a fan or ignition system, or changes to the structure, like extending the hearth, expect separate trade costs. Electricians charge $100–$150/hour. Bricklayers charge $65–$95/hour.
You need a Certificate of Compliance (CoC) from a licensed gas fitter for every gas conversion in Victoria. This isn’t optional. CoC costs are around $50–$150, including the mandatory $40.80 VBA fee.
The CoC proves that the installation follows AS/NZS 5601.1 and Victoria’s gas safety rules. You might also need building permits for any changes to the building’s structure. These permits cost between $850-$1,300.
The fireplace unit itself is a major cost driver. Gas log sets start at $800 for basic models. Premium inserts with remote controls and realistic ceramic logs cost $3,000–$6,000. High-end direct-vent units with glass fronts and Wi-Fi connectivity can exceed $8,000.
You’re not just buying a heater; you’re buying the focal point of your living room. Choose based on heat output, aesthetics, and long-term running costs.

Not every fireplace can be converted to gas. It depends on the firebox, the flue, the building, and current Victorian energy regulations.
The answer is yes, if your home already has a gas line, the chimney can be lined or relined, and the setup can vent the appliance safely.
A brick or stone masonry fireplace with a working chimney is the easiest to convert.
Conversion isn’t possible without extra work if the flue is cracked, collapsed, or too narrow for the required liner. In that case, you’ll need repairs or a full relining before a gas appliance can be installed.
In some cases, conversion is not feasible without significant structural work, especially if the fireplace is purely decorative. This is common in older Melbourne homes.
Many Victorian-era terraces have fireboxes plastered over and chimneys blocked off. Reopening them changes the scope, budget, and timeline of the project.
The only sure way to know your category is a site visit by a licensed gas fitter. You can also ask them if you want to remove a gas fireplace later.
Yes, a gas fireplace conversion makes financial and practical sense for most Melbourne homeowners. Here’s why:
But you need to think twice if your home lacks gas or needs major digging, because costs can exceed $10,000. Or if you plan to sell within two years, you likely won’t recover the conversion costs.

Yes. Under the Gas Safety Act 1997, a licensed gas fitter must undertake all gas work. This includes installing a gas fireplace insert, connecting a gas log set, extending a natural gas line, and starting up the appliance.
Remember, unlicensed gas work risks fines and voiding your home insurance for damage. And without a Certificate of Compliance, selling your property becomes a complicated matter.
You just need to book licensed gas fitting services and get the job done properly.
Choose a gas log fire insert or burner kit for your wood fireplace. Plumbing and installation start at $750. If your firebox is compliant, expect $1,500–$2,500. And remember, skip premium features like remote controls to stay in the low-cost tier.
It depends on the complexity. Converting a fireplace to gas takes 1–2 days for simple retrofits. A basic gas log set takes 2–4 hours. A mid‑range insert with some flue work takes 4–8 hours. But, for chimney repairs, long gas lines, or major structural changes, plan 2–3 days.
No, a gas fireplace shouldn’t smell like gas when it’s on. If you catch a faint smell during the first few uses, that’s normal. That’s dust burning off new parts. But a steady gas smell means there might be a leak or incomplete combustion. Find out why a gas fireplace smells like gas and what to do.
The cost to convert a fireplace to gas in Melbourne ranges from $1,500 for a simple log set to over $10,000 for a full direct-vent system with structural work. You can choose the best fit for your home’s layout and budget.
