At a Glance
Natural gas availability varies across Perth: established suburbs are generally connected, while some newer estates were built all-electric. Gas fitting work costs $200–$3,800 per job, with WA trade rates tending to run 10–15% above eastern states.
What's Included in the Price
A standard gas fitting quote covers labour, pipe and fittings, flexible connectors, pressure testing to AS/NZS 5601 Gas Installations requirements, and a compliance certificate (gas notice). Appliance connections include hookup, leak testing at all joints, and gas pressure verification. New line installations include pipe routing from the meter, wall penetrations, fixings, and full system pressure testing before sign-off. Where plumbing connections are involved, work must also comply with AS/NZS 3500 Plumbing and Drainage.
What Affects the Cost
- Gas availability: Not all Perth suburbs have natural gas. Homes without it need LPG setups or a gas main extension from the distributor (ATCO Gas), which is a separate cost.
- Pipe run distance: Perth's larger block sizes can mean longer distances from the gas meter to the appliance location. Runs of 15 to 20 metres are not uncommon in outer suburbs.
- WA trade rates: Gas fitting rates in Perth are typically higher than eastern states, reflecting WA's labour market.
- Access and routing: Sandy soil makes trenching easy, but limestone foundations in coastal suburbs can complicate pipe fixings and penetrations.
- Flexible connectors: Must be replaced at 5-year intervals. Include this in the scope of any gas work.
A straightforward appliance connection to an existing gas bayonet point in a suburban Canning Vale home sits toward $200. Running a new gas line from the meter to an outdoor alfresco area 18 metres away on a large Mundijong block, with trenching, wall penetrations, and multiple fittings, pushes toward $3,800. Most Perth jobs land around $750 for a short new pipe run or connection with connector replacement.
Gas leaks require immediate attention. If you smell gas, call ATCO Gas emergency line (13 13 52) to isolate the supply before calling a gas fitter. After-hours, weekend, and emergency gas work carries premium rates. Winter demand from April to June creates peak booking periods for gas heater connections and servicing. For non-urgent work, scheduling during business hours and outside the winter peak saves money.
Perth-Specific Considerations
Perth's natural gas network, supplied by ATCO Gas, covers most established suburbs from Joondalup to Rockingham. Several newer developments, particularly in the northern corridor (Alkimos, Yanchep) and south-east (Byford), have been built without gas reticulation. If you are in one of these areas, adding gas means paying for a main extension from ATCO plus the internal gas fitting work.
Perth winters are mild compared to Melbourne, but cold enough (5 to 10 degrees C overnight from June to August) that gas heaters remain popular. This creates seasonal demand. Booking a gas fitter for heater installation or connection in autumn is advisable before winter peak hits.
Perth's larger suburban blocks mean gas pipe runs from the meter to the house can be significant. This increases both materials and labour. On the positive side, Perth's sandy soils make trenching for buried gas lines relatively straightforward compared to rocky or clay soils elsewhere.
Coastal suburbs from Cottesloe to Scarborough can present corrosion concerns for exposed metallic gas fittings. Your gas fitter should use appropriate materials and coatings for marine-adjacent installations.
Hiring a Licensed Gas Fitter in WA
Gas work in Western Australia must be carried out by a gas fitter holding a gasfitting permit through Building and Energy (DMIRS). This is a separate permit from standard plumbing. Verify through the DMIRS online register. A compliance certificate (gas notice) must be lodged for every gas fitting job. Ask for confirmation that this has been submitted. Red flags: no DMIRS permit number, not lodging a gas notice, or quoting without inspecting the existing gas setup.
How We Calculate
Estimates are based on current trade rates for licensed gas fitters in WA, adjusted for Perth labour costs and typical material prices. All figures include GST. Ranges cover simple appliance connections through to new gas line installations.
