Gas Comparison Western Australia
Gas comparison Western Australia starts with your ATCO network area, annual gas usage, regulated maximum price status and whether you use natural gas or LPG. Kleenheat is a major WA gas retailer, but compare gas plans Western Australia-wide because market contract discounts, conditions and fees can still change the bill.
Gas comparison Western Australia: how the market works
Regulated maximum prices
WA regulates maximum standard-form natural gas prices for small-use customers in listed distribution systems. Market contracts may be cheaper or structured differently.
Retail competition is narrower
Kleenheat, Alinta, AGL and Origin are prominent household gas names in WA. Competition exists, but it is narrower than electricity and varies by licence area.
Western Australian gas distribution networks
ATCO operates WA's largest reticulated gas network. If your property is outside a connected gas distribution system, LPG or electric appliances may be the practical comparison point.
ATCO Gas Australia
Perth metro, Mid West, South West, Geraldton, Kalgoorlie, Bunbury, Albany and connected towns
ATCO operates WA's largest reticulated gas network, with more than 14,500 km of pipeline serving over 800,000 homes and businesses.
Mid-West and South-West Gas Distribution Systems
Main regulated gas distribution systems
ERA-approved access arrangements and 2026 tariff variations apply to the Mid-West and South-West gas distribution systems.
Albany Gas Distribution System
Albany LPG reticulation
ATCO identifies Albany as an LPG gas distribution system. LPG arrangements can differ from standard natural gas plans.
Bottled LPG and off-network gas
Regional WA, farms, holiday homes and properties outside reticulated supply
Regulated maximum natural gas prices do not apply to reticulated LPG systems in Margaret River, Leinster and Esperance, or to bottled gas.
Current WA gas reference prices and regulated rates
WA is different from eastern states because some household gas prices are capped by regulated maximum tariffs. Compare those maximum prices with market contract discounts before switching.
| Benchmark | Current value | What it means |
|---|---|---|
| Regulated maximum gas price | Applies to standard form contracts in defined WA gas systems | WA regulates maximum natural gas prices for small-use customers consuming less than one terajoule per year in listed distribution systems. |
| Market contract comparison | Retailers may offer non-standard pricing | Retailers can offer market contracts below or structured differently from the regulated maximum price, so compare discounts, conditions and fees. |
| ATCO 2026 network tariffs | 2026 tariff schedule published | ATCO published 2026 reference tariffs for the Mid-West and South-West Gas Distribution Systems under its 2025-2029 access arrangement. |
| Natural gas and LPG coverage | Both matter in WA | Natural gas is common in the ATCO network area; LPG remains relevant for off-network properties and some reticulated systems. |
Western Australian gas rebates and concessions
Cheap gas Western Australia comparisons should not assume a gas rebate. WA has broader energy assistance, but the ERA consumer guide states there are no WA Government concessions specifically available through natural gas.
WA Government does not provide a natural gas concession rebate for reticulated natural gas customers
Energy Assistance Payment supports eligible household energy costs, including electricity and gas consumed in the home
Energy Concession Extension Scheme payment amounts from 1 July 2025 include $342.85 for the Energy Assistance Payment
Dependent Child Rebate and Air Conditioning Rebate may support broader household energy costs for eligible households
Life Support Equipment Electricity Subsidy and Thermoregulatory Dysfunction Energy Subsidy can apply where electricity use is medically required
Bottled LPG and non-standard gas arrangements should be checked directly with the supplier because state natural gas rebates do not apply
