Gas fitting cost Melbourne — what to expect in 2026

Gas fitting in Victoria must be carried out by a licensed gasfitter — it's a legal requirement and a safety imperative. Here's a full breakdown of what gas fitting work typically costs in Melbourne in 2026, and what you need to know before getting work done.

Gas fitting costs at a glance

Job type	Typical cost range
Gas appliance connection (cooktop, oven)	$150–$350
Gas bayonet fitting installation	$200–$400
New gas line installation (short run)	$400–$900
New gas line installation (long run or complex)	$900–$3,000+
Gas leak detection and repair	$200–$600

Compliance certificate (Cert of Compliance)	Included in most jobs
Gas safety check / inspection	$150–$300

What affects the cost of gas fitting work?

• Length and complexity of the gas line — a short connection to an existing bayonet costs much less than running new gas pipe through walls or under floors

• Accessibility — gas lines in difficult locations (under concrete, through multiple walls, in roof spaces) cost more to install

• Existing infrastructure — if your home already has a gas connection and adequate pressure, appliance connections are straightforward. Connecting to gas for the first time involves coordinating with your gas distributor (AusNet or Multinet in Melbourne) which adds time and cost

• Type of appliance — a gas cooktop connection is simpler than a gas outdoor kitchen or commercial-style range requiring larger pipe sizing

  
  

Certificates of compliance — what are they?

In Victoria, all licensed gas work must be certified with a Certificate of Compliance issued by the gasfitter who performed the work. This certificate is registered with Energy Safe Victoria and proves the work was carried out correctly and to the applicable standards. Always ask for your certificate — it's important for insurance purposes and for any future sale of the property.

Reputable gasfitters include the certificate as part of the job. If a tradesperson refuses to provide a certificate or charges extra for it on work they've completed, treat this as a significant warning sign.

Getting a new gas connection in Melbourne

If your home doesn't have a gas connection and you want to add one, the process involves: engaging a licensed gasfitter to install the internal pipework and appliances, contacting your gas distributor (AusNet Services for most of Melbourne) to connect the supply, and paying a new connection fee to the distributor (typically $300–$800). The full process from application to active connection usually takes 2–6 weeks.

Gas leaks — what to do

If you can smell gas: Do not use any electrical switches, naked flames, or appliances. Open windows and doors, leave the property, and call 1800 GAS GAS (1800 427 427) — the 24-hour gas emergency line — and then call a licensed gasfitter. Do not re-enter the property until it has been declared safe.

For suspected minor gas leaks (intermittent smell, appliance not lighting reliably), call a licensed gasfitter for a pressure test and inspection. Gas leak detection and repair typically costs $200–$600 depending on what's found.
