    Retailers

    Electricity consumers in Western Australia fall into two general categories, contestable and non-contestable customers. Contestable customers have a choice of electricity retailer, while non-contestable customers do not.

    Find out about which electricity retailers you can use in the Economic Regulation Authority’s guide:

    Non-contestable customers

    Non-contestable customers are customers within the South West Interconnected System consuming less than or equal to 50 megawatt hours of electricity a year (an average of 137 units per day).

    These customers are supplied by Synergy and pay electricity prices regulated by the Western Australian Government as determined under electricity by-laws.

    Residential households and small businesses usually fall within this category.

    Contestable customers

    Contestable customers are customers within the South West Interconnected System consuming more than 50 megawatt hours of electricity a year (an average of 137 units per day). These include

    • small to medium sized businesses
    • large businesses.

    All customers outside of the South West Interconnected System are contestable and can choose their retailer. Customers should be aware that, at present, Horizon Power is the only retailer in many regional areas.

    These customers can negotiate the rates they pay with their chosen retailer.

    Customers consuming between 50 and 160 megawatt hours per year can choose to either pay the relevant capped rates offered by Synergy or be supplied by Synergy or another retailer at negotiated tariff rates.

    On sellers

    Make a complaint

    The Public Utilities Office does not resolve customer service or billing complaints.

    If you have a complaint about your electricity supply, the first step is to contact your retailer. Residential and small business customers (annual consumption less than 160 megawatt hours), that are still unable to resolve the issue, can contact the Energy Ombudsman. For more information, refer to the Economic Regulation Authority’s advice.

    Safety advice and electrical equipment

    For advice on using electricity safely, licensing of tradesmen, and safety of electrical installations and equipment, contact EnergySafety at the Department of Commerce.
