Natural gas prices for certain small use customers (those who consume less than one terajoule per year) are regulated. This applies to small use customers serviced by gas distribution systems in the:
Mid West/South West;
Kalgoorlie-Boulder;
Albany;
Geraldton and surrounding areas;
Carnamah; and
Perth metropolitan area extending north to Gingin and south to Busselton supply areas.
The Energy Coordination (Gas Tariffs) Regulations 2000 explain the regulated maximum price retailers can charge small use customers in these areas. The maximum price applies for supply under a standard form contract and retailers may offer other pricing arrangements under market (or non-standard) contracts.
Regulated maximum prices do not apply to the reticulated LPG systems in Margaret River, Leinster and Esperance, or to bottled gas.
Gas retailers that supply large users are not bound by the regulated maximum prices for supply to those customers.
Gas retailers may charge fees additional to the regulated maximum prices. The government does not regulate these additional charges.
Choice of Retailer
Show moreSmall use customers can choose to buy natural gas from any licensed gas retailer. These retailers cannot charge above the regulated price cap when offering to supply small-use customers under a standard form contract, but can offer lower prices through non-standard form contracts.
