There are a number of government incentives still available. Often these incentives can be different depending on your geographical location (including state) and may only apply to certain household statuses (ie. Owner, Landlord, Renter etc).

Some of the current rebates are listed below.  For all of the current national rebates, check out the Government’s Energy Savings site for the most up to date information.

Hot Water Systems – All States

Households across Australia that install a small scale renewable energy system or eligible hot water system may be able to receive a benefit under the Small-scale Renewable Energy Scheme (SRES) to help with the purchase cost.

Installing an eligible system allows the creation of Small-scale Technology Certificates (STCs), an electronic form of currency with a value that can be redeemed by selling or assigning them.


The Energex Hot Water Rewards scheme provides a rebate of up to $200 to eligible South East Queensland households that connect an electric hot water system to an off-peak electricity tariff.

Households benefit by accessing the savings of a cheaper electricity rate as well as helping to reduce peak electricity demand


The Energy Saver Incentive helps Victorian households and businesses save energy and money with a range of discounts and special offers on selected energy-saving products and services.

All sorts of organisations can participate in the initiative, including energy retailers and local appliance stores, as well as plumbers, builders and other tradespeople.

Discounts and special offers are only available from participating businesses. Make sure you ask your retailer or tradesperson if they’re registered as a participating business under the Energy Saver Incentive program or view the register of participating businesses online.

Solar Hot Water Rebates

When installing a solar hot water system, you’re eligible for two types of rebates.

1) STC’s (Small-scale Technology Certificates)

Your new solar water heater or heat pump is eligible for this type of rebate if it is listed in the Register of Solar Water Heaters. You may claim a set number of STC‘s (Small-scale Technology Certificates).

This number is based on the amount of electricity in megawatt hours (MWh) displaced by your solar water heater or heat pump over the course of its lifetime, up to ten years. (where one MWh equals one STC).

The amount of cash that you receive, will depend on a number of varying factors. These include:

  • Where you live in Australia.
  • The efficiency of your Solar Hot Water System.
  • What kind of system is being installed.
  • The current price of STC‘s on the market.

You can expect to receive approximately $300 – $1000 for your STC‘s, taking into account the factors above.

2) State Rebate
