The Western Australian Government regulates the maximum amount that retailers can charge for the supply of natural gas to businesses, government and non-residential customers who consume under one terajoule each year. These regulated charges are known as non-residential tariffs and include the daily supply charge and gas usage tariffs.
Non-residential tariffs apply to non-residential customers that are 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 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 price. The Government does not regulate these additional charges.
Choice of retailer
Show moreSmall use, non-residential 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.

Who do I contact if I have an issue with my gas supply?
Show moreYou should first reach out to your gas retailer if you have a problem or complaint.
If that hasn’t resolved the issue, the Energy and Water Ombudsman WA is an independent body that can help you resolve the issue with your retailer.
The Ombudsman can assist with issues such as:
- Billing or metering concerns;
- Customer service issues;
- Issues with getting a connection;
- Any damage to land or property by your retailer; and
- Lack of notification of price changes
If you feel your retailer is charging above the regulated tariff, contact the Energy and Water Ombudsman.
