Are you eligible to claim the Government’s STCs when you buy a new hot water system?
The Australian Federal Government encourages households to switch to more energy-efficient hot water systems, including eligible solar hot water systems and heat pump water heaters, through the Small-scale Renewable Energy Scheme (SRES).
Under this scheme, eligible systems may qualify for Small-scale Technology Certificates (STCs), which can help reduce the upfront purchase and installation cost of your new hot water system.
By upgrading to an eligible solar hot water or heat pump system, you may receive a financial benefit through STCs, potentially saving hundreds or even thousands of dollars, depending on the system installed and your location.
The number of STCs your system may be eligible for depends on several factors, including:
- The type and size of the system
- The model installed
- The installation location and climate zone
- The system’s expected energy efficiency and renewable energy contribution
- The remaining deeming period under the scheme
STCs have a market value and can typically be assigned to your installer in exchange for an upfront discount on the purchase price of your new system.
STC rebates reduce each year
The Small-scale Renewable Energy Scheme is gradually reducing each year and is currently scheduled to end in 2030. As the scheme phases down, the number of STCs available for eligible systems decreases annually, meaning rebate values become smaller over time.
If you are considering upgrading to an energy-efficient solar hot water or heat pump system, acting sooner may help maximise the rebate available under the current scheme.
