Key Takeaways
Simple gas appliance connections usually cost less than new gas line runs, leak repairs, or complex LPG and natural gas conversions.
Pipe length, wall or floor access, ventilation, appliance type, and compliance testing can materially affect the final price.
Gas work should be completed by an appropriately licensed gas fitter and supported by the required compliance documentation.
A clear quote should separate call-out fees, labour, pipework, fittings, appliance connection, testing, certification, and exclusions.
Overview
Gas fitting costs depend on the type of appliance or repair, gas line location, pipework length, LPG or natural gas supply, access, ventilation, compliance requirements, testing, certification, and whether existing gas infrastructure needs upgrading or rectification.
1. Typical Gas Fitting Costs
Gas fitting costs vary according to the appliance type, gas supply, pipework length, access, materials, testing, certification, and whether the job involves repair, installation, conversion, or a new gas outlet.
Minor Gas Fitting Work
$180 – $600
Basic inspection, gas leak diagnosis, minor fitting replacement, appliance disconnection, or simple gas safety check.
Gas Appliance Installation
$350 – $1,500
Connection of a gas cooktop, oven, heater, barbecue point, or other appliance where existing gas supply is suitable.
New Gas Point or Bayonet
$800 – $2,500
New gas outlet, bayonet point, pipe extension, wall or floor access, pressure testing, and compliance certification.
Major Gas Line or LPG Work
$2,500 – $4,500+
Long pipe runs, LPG bottle station setup, regulator work, appliance conversion, difficult access, or rectification of non-compliant gas work.
2. What Affects the Cost?
The main cost differences usually come from appliance requirements, pipe routing, wall or floor access, LPG or natural gas setup, leak diagnosis, ventilation, and compliance work.
Appliance Type
Cooktops, heaters, ovens, hot water units, fireplaces, and outdoor appliances each have different connection and compliance requirements.
Pipework Length & Route
Longer gas line runs, wall penetrations, roof or subfloor access, and concealed pipework increase labour and materials.
Gas Supply Type
Natural gas, LPG bottles, regulators, appliance conversion kits, and meter or bottle-station locations can change the scope.
Testing & Compliance
Pressure testing, leak checks, ventilation requirements, flue checks, and compliance certificates are important parts of safe gas work.
3. Cost Breakdown
A gas fitting quote commonly combines licensed labour, pipework, fittings, appliance connection, testing, compliance certification, travel, access work, and cleanup.

4. Gas Appliance Connections, LPG and Compliance
Gas fitting quotes should clearly explain the appliance connection method, gas supply assumptions, and compliance requirements.
For appliance installation, confirm whether the quote includes disconnection of the old appliance, new isolation valves, flexible hose, regulator checks, ventilation assessment, flue checks if required, pressure testing, commissioning, and instructions for safe operation.
LPG and natural gas systems may require different regulators, jets, conversion kits, pipe sizing, bottle placement, meter clearances, and compliance checks. The quote should state whether the appliance is suitable for the available gas type and whether any conversion parts are included.
5. Gas Fitting Quote Checks
Before accepting a gas fitting quote, confirm the exact appliance, gas supply, pipework, testing, certification, and exclusions.
Confirm whether the call-out fee, labour, pipework, fittings, appliance connection, testing, and cleanup are included.
Ask for the gas line route, pipe material, valve locations, regulator requirements, and appliance connection method.
Check whether leak repairs, wall access, floor access, ventilation upgrades, LPG conversion, and old appliance removal are included or excluded.
Confirm that pressure testing, commissioning, compliance documentation, product warranties, and workmanship warranties are itemised.
7. Questions to Ask Before Hiring a Gas Fitter
Use these questions to compare gas fitting quotes and reduce the risk of unsafe work or unexpected variations.
Does the price include the call-out fee, labour, materials, appliance connection, testing, certification, and cleanup?
What pipework, valves, regulators, hoses, fittings, appliance parts, and warranties are included?
Could hidden leaks, undersized pipework, access issues, ventilation problems, or non-compliant work trigger variations?
Is the appliance suitable for natural gas or LPG, and are any required conversion parts included?
Are wall access, floor access, old appliance removal, disposal, travel, and final cleanup included?
What conditions would trigger a revised quote, and how will additional gas work be approved and priced?
