A state premier and treasurer are turning up the heat on energy retailers, threatening to “name and shame” companies that fail to pass on electricity savings.

The comments come in the run-up to Queensland’s state budget, to be handed down by Treasurer David Janetzki on Tuesday.

Premier David Crisafulli warned energy retailers would be given “a very small window” to pass on savings to consumers.

“Watch out, because you’re going to be named and shamed, and we’ve many levers at our disposal,” he told reporters in Brisbane on Sunday.

“Watch this space on Tuesday if it doesn’t start happening.”
