Gas Cooktop Installation Cost in Melbourne (2026 Guide)

Australian licensed plumber working on gas cooktop installation cost in melbourne (2026 guide) at a Melbourne home — Prime Plumbing & Gasfitting

Gas Cooktop Installation Cost in Melbourne (2026 Guide) — a Prime Plumbing & Gasfitting plain-English guide to gas cooktop installation cost melbourne for Melbourne homeowners. Below we cover what works, what doesn't, and when to call a licensed plumber.

Quick answer: A straight-swap gas cooktop installation in Melbourne typically runs $280–$450 if your existing supply line, isolation valve, and benchtop cut-out are all compatible. If new gas pipework is needed (running a fresh supply line from the meter or extending an existing line), expect $650–$1,400 depending on distance and complexity. Adding a new gas point during a kitchen renovation often lands in the $1,200–$2,800 range when combined with cabinetry coordination and an Energy Safe Victoria Compliance Certificate. Every gas cooktop install in Victoria legally requires a licensed Type A gasfitter — DIY is illegal under the Gas Safety Act 1997. The compliance certificate cost (around $90) is included in our quotes.

What you actually pay for

A gas cooktop installation isn't just bolting an appliance to a benchtop — it's gas-carrying pipework, an electrical connection (most cooktops need 240V for ignition and safety features), a benchtop cut-out matched to manufacturer tolerances, and a Compliance Certificate lodged with Energy Safe Victoria. Skipping any of these is illegal, and skipping the compliance certificate alone can void your home insurance if a fire or gas event ever occurs.

The big cost variables, ranked roughly by impact:

  1. Whether you need new gas supply pipework, or just a swap — biggest single variable
  2. Whether the existing benchtop cut-out matches the new appliance — varies hugely between brands and sizes
  3. Whether the meter has spare capacity for the new appliance load
  4. Distance from gas meter to the cooktop — affects pipe sizing under AS/NZS 5601
  5. Single-skin vs double-skin or stone benchtop — cut-out cost differs
  6. Brand and complexity of the cooktop itself (the appliance you buy is separate from install)

When a simple swap turns into a full re-pipe

You buy a 90cm 6-burner replacement for an old 60cm 4-burner. The new appliance peak demand is double, your existing gas line is sized for the old load, and the meter is at capacity. What looked like a $400 install becomes: new 1/2" gas line from the meter, possible meter upgrade with your gas distributor, benchtop cut-out adjustment, plus the install. Total 4-8 hours of work and $1,200-$2,500 depending on access. We do the gas load calculation up front so the quote reflects reality not optimism. See our gas fitting page.

Typical Melbourne pricing scenarios

Honest ranges based on what we actually quote for. These don't include the appliance itself — that's whatever you've bought from Harvey Norman, Bing Lee, Appliances Online, or your kitchen designer.

Scenario 1 — straight swap, same size, existing gas point

You're replacing a gas cooktop with another gas cooktop of the same physical size. The gas isolation valve under the benchtop is in good condition. The benchtop cut-out matches.

  • Disconnect old appliance, recover for disposal: included
  • Reconnect new appliance with appropriate appliance hose
  • Pressure test, leak test, flame quality check
  • Compliance Certificate to ESV
  • Total: $280–$450

This is the cheapest scenario and represents maybe 30% of our jobs. Time on site is usually 60–90 minutes.

Scenario 2 — straight swap, different size, new cut-out needed

Same as above but the new cooktop is a different size or shape. The benchtop cut-out has to be enlarged or a benchtop infill panel may be needed.

  • Stoneworking subcontractor (if stone) or bench saw work (if laminate): typically $200–$600
  • Plumbing/gas portion: $280–$450 as above
  • Total: $480–$1,050

Stone benchtops cost more because cutting requires a stoneworking specialist with diamond tooling and water containment. Don't try this with an angle grinder — it shatters.

Scenario 3 — new gas point, no existing supply

The kitchen has electric cooking now, you're switching to gas. We need to run new pipework from the gas meter to the cooktop location.

  • Gas pipework run (typically 6–15 metres copper or PEX-AL-PEX): $400–$900 depending on routing complexity (under-floor access, ceiling space, behind cabinetry)
  • Isolation valve, regulator if needed: $80–$150
  • Cut-out and install: as Scenario 1 or 2
  • Meter capacity check, possible upsize coordination with gas network operator: variable
  • Total: $650–$1,400

If your gas meter is at maximum capacity (common in older homes with limited supply) and the network operator needs to upgrade the meter or the lateral connection from the street, that's a separate cost we coordinate but don't control — usually $300–$800.

Scenario 4 — full kitchen renovation context

You're doing a kitchen renovation and the gas cooktop is one element of a bigger job. Cabinetry is being replaced, benchtops are new, and we're working alongside a builder/designer/electrician.

  • Pre-render gas point rough-in: $400–$700
  • Final connection after benchtop install: $250–$400
  • Benchtop cut-out: handled by stonemason or cabinetmaker
  • Compliance Certificate: included
  • Total: $1,200–$2,800 (gas portion only — full kitchen reno is much higher overall)

The premium reflects more site visits (rough-in, then final), coordination with other trades, and often more complex pipework if appliances are being relocated.

What's legally included in every gas cooktop install

These aren't optional — they're required under AS/NZS 5601 and Victorian gas safety law. Any quote that omits them isn't a real gas install:

  • Pressure test of the gas line at appliance pressure (1.13 kPa for natural gas) and at higher test pressure
  • Leak test at every joint with leak-detection solution
  • Flame quality check at every burner — flame should be predominantly blue with sharp inner cone, no yellow tipping or lifting
  • Compliance Certificate lodged with Energy Safe Victoria within 5 days
  • Customer copy of the Compliance Certificate kept on file (you'll want this if you ever sell the property)

If a quote is significantly cheaper than the ranges above, ask the gasfitter to confirm in writing that all five items are included. If they hedge, walk away — you're being offered an illegal install.

Why some quotes vary by hundreds of dollars

Same job, three different gasfitters, three wildly different prices. The honest reasons:

  • Different appliance hoses: a long flexible appliance hose with quick-release coupling vs. a short hard-pipe connection are different parts at different prices
  • Pipework material: copper vs. PEX-AL-PEX vs. galvanized — copper is most common, PEX is faster on long runs, galv is older-school but slower to install
  • Whether they're including the compliance certificate in the quote, or separately invoicing it
  • Scheduling: same-day priority callouts cost more than booked-ahead jobs
  • Disposal of the old appliance — some quotes include, some don't

When comparing quotes, ask each gasfitter to itemise materials, labour, compliance certificate, and disposal. Apples-to-apples comparisons are much cleaner once you do that.

When you should also budget for related work

Often a "simple cooktop swap" reveals other issues:

  • Old isolation valve: if it's stiff, leaking, or pre-mid-century brass, replace it ($80–$150 part + labour)
  • Aged appliance hose: hoses have a 10-year service life; if the existing one is older we'll recommend replacement ($60–$120)
  • Inadequate range hood: not strictly required but stronger ventilation is recommended for higher-output gas burners
  • Carbon monoxide alarm: if you have a flueless gas heater elsewhere in the home, AS 4625 recommends a CO alarm ($45–$120)

We'll flag these on-site and you can decide whether to bundle them in or schedule separately.

What you can do yourself (DIY-safe scope)

Before the gasfitter arrives, you can legally and safely:

  • Buy the cooktop (and read the installation manual — manufacturer cut-out dimensions matter)
  • Clear the cabinetry below so the gasfitter can access the connection point
  • Confirm the electrical situation — most modern gas cooktops need a 240V supply nearby. If the existing electric cooktop's circuit is being decommissioned, you may need an electrician to re-purpose or relocate the outlet
  • Decide on the appliance hose location — usually behind the cabinetry on the rear wall, but consult the gasfitter
  • Disconnect the old gas appliance yourself
  • Run any new gas pipework
  • Cut into existing gas lines
  • Connect the new appliance to the gas supply

What you cannot do under Victorian law: These are gasfitter-only tasks and doing them without a Type A gasfitter licence is illegal — and your home insurance will not cover any incident on DIY gas work.

Frequently asked questions

No. Even a like-for-like swap where you're using the same gas point requires a licensed Type A gasfitter under Victorian law. The penalty for unlicensed gas work is up to $40,300 for an individual, plus your home insurance becomes void. There are no exceptions for "simple" swaps.

A straight swap is usually 60–90 minutes including testing. A new gas point install runs 3–5 hours. A kitchen renovation rough-in plus final fit is typically two visits, totalling 5–8 hours.

Yes — at least someone over 18 needs to be home so we can access the property, demonstrate operation of the new appliance after install, and have you sign the Compliance Certificate paperwork.

Type A covers domestic and most commercial appliances under 500 MJ/h — which includes all residential cooktops, ovens, hot water units, and heaters. Type B covers larger industrial appliances. For your home, Type A is what you need. Always ask to see the gasfitter's licence card.

We will if you ask in advance — there's usually no extra charge for this. Some councils accept gas appliances at hard rubbish collection. Don't put it out for the regular bin.

Could be. Weak flames after a recent install usually mean either insufficient gas pressure (pipework too small, regulator issue) or partial blockage in the burner orifices. Both are warranty issues — call the installer back. After several years of use, weak flames are usually burner orifice debris and can be cleaned during a service.

In Victoria, switching from electric to gas usually costs $1,000+ more than a like-for-like gas swap because of the new pipework. Running cost depends on your usage, but gas is generally cheaper per cooking session than electric resistance, comparable to induction. The Victorian government is encouraging electrification (heat pumps, induction) for environmental reasons — worth weighing if you're in a long-term decision.

Yes — workmanship warranty covers the gasfitter's connections and pipework for 12 months minimum (longer at our discretion for new installs). The appliance itself is covered by the manufacturer's warranty (usually 1–5 years depending on brand).

Before You Book

A quick checklist to share with your plumber when you book:

  • When did the issue start?
  • Is it isolated to one fixture or multiple areas?
  • Are there any visible leaks, smells or unusual sounds?
  • Have you turned off the relevant isolation valve?
