Diamond Energy has incurred penalties totalling $46,950 following the issuance of three infringement notices by the Australian Competition and Consumer Commission (ACCC) in response to allegations company breached the Electricity Retail Code by failing to communicate mandatory pricing information to three customers.

The ACCC's investigation revealed that Diamond Energy had sent communications to 12,809 customers in June 2024 without including the required pricing information as stipulated by the Code. Additionally, the company admitted to not displaying the necessary pricing details on its website for 44 electricity plans from 1 January to 30 June 2024, and for another 44 plans between 1 July and 20 September 2024.

The Electricity Retail Code mandates that electricity retailers provide specific pricing information to residential and small business customers when advertising, publishing, or notifying about price changes. This Code is applicable to electricity retailers operating in New South Wales, South Australia, and South East Queensland.

Diamond Energy has acknowledged its contravention of the Code and has provided a court-enforceable undertaking to the ACCC. As part of this undertaking, the company has committed to implementing a compliance program to ensure adherence to the Code in the future.

ACCC Commissioner Anna Brakey said: "By not disclosing the required pricing information to its customers, Diamond Energy has impacted consumers’ ability to make an informed decision when comparing prices across electricity retailers.

"It is vital that electricity retailers provide consumers with accurate information so they can compare and access the most competitive prices in the market."

The ACCC has a history of enforcing compliance with the Electricity Retail Code. Since its introduction in 2019, several companies, including Locality Planning Energy, CovaU, ReAmped Energy, and Dodo Power & Gas, have received infringement notices for similar breaches. In a notable case, the Federal Court ordered Energy Australia to pay $14 million in penalties in September 2024 for misleading statements and failing to provide mandatory information under the Code.

The ACCC's Compliance and Enforcement Priorities for 2025-26 include a focus on addressing misleading pricing and claims in essential services, with particular attention on the energy and telecommunications sectors. "We will continue to monitor electricity providers to ensure they adequately disclose pricing information to consumers," said Brakey.
