Gas Cooktop Installation Costs

We inspect the job and confirm the price before work begins. If you are in the St George or Sutherland Shire area and replacing an existing gas stove, the job is quick for a licensed gasfitter. Installing a brand-new gas point in a kitchen that has never had gas is a bigger task, and the price reflects it.

How much does gas cooktop installation cost in Sydney in 2026?

The table below gives realistic cost ranges for the most common scenarios. These are labour-only estimates and assume the cooktop itself is already purchased. Material costs (pipe fittings, flexible hose, isolation valve) are extra and vary by situation.

Prices above are indicative for southern Sydney in 2026 and move with labour rates and pipe run length. A straightforward swap on an existing gas point sits at the cheaper end. We inspect the job and confirm the price before work begins. Always get a written quote that includes the Certificate of Compliance before work begins.

Can a plumber install a gas cooktop, or do you need a gasfitter?

In NSW, any work on a gas installation must be carried out by a licensed gasfitter. Some plumbers hold a gasfitting licence as well, which means one tradesperson can handle both jobs. But the gasfitting licence category is not automatically included in a standard plumbing licence. Check that the person you book holds a current NSW Fair Trading gasfitting licence before any work starts.

You can verify a licence on the NSW Fair Trading licence check page. Requirements can vary by property and authority. We will help you confirm what applies before work begins. There is no grey area here.

EKORP Plumbing holds the necessary gasfitting qualifications to carry out this work legally across the Bayside, St George, and Sutherland Shire areas. Our residential gas plumbing services cover cooktop connections, new gas points, pressure testing, and compliance certification.

What is a Certificate of Compliance for gas work?

After any gas installation or alteration, the licensed gasfitter must issue a Certificate of Compliance (gas). Requirements can vary by property and authority. We will help you confirm what applies before work begins. Without it, you have no record that the installation is safe and code-compliant.

Why does the certificate matter beyond the paperwork? If you sell your home, your conveyancer or the buyer’s inspector may ask for it. If a gas-related incident occurs and no certificate was issued, your insurer may decline the claim. Keep the certificate with your home records.

Ask your gasfitter before they start: “Will you issue a Certificate of Compliance?” A straightforward yes is the right answer. If they hesitate or say it is not needed, walk away.

What affects the cost of installing a gas cooktop?

Six things tend to move the price:

• Existing gas point or new run. Connecting to an existing, correctly sized bayonet or flexible hose point is fast. Running new pipe from the meter or existing line adds time and materials.
• Natural gas or LPG. LPG appliances use different injectors and regulators. Converting between fuels requires additional parts and a pressure check.
• Access and wall construction. Brick veneer kitchens with concealed pipes under the bench are manageable. Older homes with solid brick walls, or kitchens on upper floors, take longer.
• Burner count and output. High-output wok burners may need a larger pipe diameter or a dedicated flexible connection rated for the flow rate. Check the cooktop spec sheet before booking.
• Kitchen renovation context. If the cooktop is going in as part of a broader kitchen renovation, booking the gasfitter alongside other trades often reduces the overall call-out cost.
• After-hours bookings. Standard business hours are cheapest. Weekend and late-evening slots carry a surcharge.

Natural gas vs LPG: which costs more to run?

If your home already has natural gas connected to the street, it is almost always cheaper to run than bottled LPG. Natural gas is priced per megajoule on a continuous supply contract. LPG is bought in cylinders and the per-MJ cost is generally higher, particularly for households that cook frequently.

If your street has no natural gas main, LPG is the practical alternative. The installation cost is similar once you account for the regulator and injectors. The ongoing cylinder swap is an added step but manageable for most households.

For homes weighing up gas versus electric, our post on gas water heater vs electric running costs has a useful breakdown of gas versus electric energy pricing that applies broadly to cooking appliances too.

Is it worth converting an electric cooktop to gas?

Converting from electric to gas cooking is a popular choice in Sydney kitchens where natural gas is already connected for hot water or heating. Gas responds instantly to temperature changes in a way induction cannot quite replicate for certain cooking styles.

The cost depends largely on whether gas is already near the kitchen. If the hot water service is on the same wall or close by, a licensed gasfitter can often extend the pipe run for a few hundred dollars in labour and fittings. If the kitchen is on the opposite side of the house from the gas meter, the run is longer and the cost climbs accordingly.

The right time to make this switch is during a kitchen renovation, when walls are open and runs can be laid without damaging finished surfaces. Waiting until the kitchen is done risks tile and cabinet damage to route the pipe through.

If you are also considering updating your hot water at the same time, our gas fitting regulations guide for the Georges River area covers what work triggers a compliance inspection and what does not.

Gas leak safety: what to check after installation

Once the cooktop is connected and the Certificate of Compliance issued, the gasfitter will pressure test the line and check every joint with a leak detector. That said, it pays to know the warning signs in the first few weeks after a new connection.

A rotten egg or sulphur odour, dead vegetation around external pipe runs, or a hissing sound near the appliance are all reasons to act immediately. Our post on when a gas smell is a real emergency explains exactly when to evacuate and when the smell is just a pilot light issue. EKORP Plumbing also offers gas leak detection across southern Sydney using electronic sniffers and pressure testing.

How do I find a licensed gasfitter in southern Sydney?

The most reliable method is to search the NSW Fair Trading licence search and confirm the tradesperson’s gasfitting licence is current before booking. Ask for the licence number and check it yourself. A reputable gasfitter will have no problem with this.

Word of mouth from neighbours works well in areas like Rockdale, Kogarah, Hurstville, Miranda, and Cronulla, where local trades tend to run on repeat referrals. Online reviews that mention compliance certificates and pressure testing are a reasonable indicator of quality.

Does gas cooktop installation require council approval in NSW?

In most cases, no. Connecting a cooktop to an existing gas supply, or extending an existing domestic gas line within the same property, does not require a Development Application in NSW. The Certificate of Compliance issued by the licensed gasfitter is the relevant compliance document. The exception is if you are changing the gas meter size or altering the service connection at the street. In that case, the network distributor (Jemena for most of Sydney) must be notified. Your gasfitter will advise if this applies to your situation.

For more on what gas work in the area triggers formal inspections, see our gas fitting compliance guide for the Georges River area, which covers the rules that apply across Bayside and surrounding councils.

Can I install a gas cooktop myself in NSW?

No. Under NSW law, carrying out gas installation work without a current gasfitting licence is an offence. This applies to homeowners as well as unlicensed tradespeople. The prohibition covers connecting the appliance, replacing the flexible hose, and adjusting the regulator. The one thing a homeowner can legally do is light the appliance after a licensed gasfitter has connected it and issued the compliance certificate.

The safety risk is real, not theoretical. A poorly connected flexible hose or an unchecked regulator can produce a gas leak that goes undetected until it reaches ignition concentration. Insurance claims related to unlicensed gas work are routinely declined. We inspect the job and confirm the price before work begins.

What should I ask for when getting quotes?

Before accepting any price, ask each gasfitter these five questions:

1. Are you licensed for gasfitting in NSW? (Ask for the licence number.)
2. Does the quote include a Certificate of Compliance?
3. Does the price include the flexible hose and isolation valve if they need replacing?
4. What is the charge if the pipe run is longer than expected?
5. Is there a call-out fee on top of the labour rate?

A gasfitter who answers all five clearly, in writing, is worth booking. If the Certificate of Compliance is listed as an optional extra or described as “not usually needed”, choose someone else.

Our guide to what plumbing jobs cost in Sydney covers call-out fees, hourly rates, and when to expect materials charged on top of the quoted price.

Is gas cooktop installation covered under home insurance?

Standard home and contents insurance in Australia does not cover the cost of routine installation or appliance connection. Damage caused by a faulty gas installation (fire, explosion, property damage) is typically covered, provided the original work was carried out by a licensed gasfitter and a Certificate of Compliance was issued. If unlicensed work is found to be the cause, most policies will decline the claim. Keep your compliance certificate with your insurance documents.

How long does gas cooktop installation take?

A straight swap at an existing gas point takes one to one and a half hours. That covers disconnecting the old appliance, connecting the new one, performing a pressure and leak test, and issuing the compliance certificate. A job requiring a new pipe run will take two to four hours depending on the run length and access. Concealed pipework in a finished kitchen takes longer than surface-mounted runs in a laundry or outdoor area.

What is the difference between a gas bayonet fitting and a hard-piped connection?

A gas bayonet is a push-and-twist quick-release fitting, usually installed at wall or bench height, that lets a flexible appliance hose be connected and disconnected without tools. Hard-piped connections use fixed copper or steel pipe run directly to the appliance location, typically with a flexible hose as the final link. Cooktops in Australian kitchens are almost always connected via a flexible hose to either a bayonet or a fixed outlet. The type already in your kitchen will shape the connection method your gasfitter uses. Our post on gas fitting compliance in the Georges River area explains the standards that apply to both.

How much does it cost to add a gas point to a kitchen that has never had gas?

We inspect the job and confirm the price before work begins. If the house is already on the natural gas network and the meter is reasonably close to the kitchen, the lower end is more likely. Homes on LPG will also need a regulator and cylinder installation if one is not already in place. Get two or three quotes and confirm each one includes the compliance certificate.
