ACCC issues 250 carbon tax substantiation notices in a week

GAS and electricity retailers and producers are on notice to ensure they pass on the carbon tax repeal savings to consumers.

The Australian Competition and Consumer Commission this week issued more than 250 "substantiation notices" to gas and power suppliers and importers.

Part of the Abbott government's policy to ensure any possible savings from the repeal are passed on, the notices are the latest step in passing on the savings.

Customers, both homes and businesses, will receive a notice from their gas and power suppliers by mid-September, showing how much they can expect to save.

Those statements will include an average annual percentage or dollar savings attributed to the repeal, to help people understand how and if it has actually saved them money.
