What is the Cheaper Home Batteries Program?
The federal Cheaper Home Batteries program is a $7.2 billion initiative providing approximately $252 per kWh (~30% off) on the first 14 kWh of an eligible battery system. It is available to all Australian homeowners with solar when using a SAA-accredited installer.
Since 1 May 2026, tiered rates apply: the first 14 kWh receives 100% of the STC factor, 14 to 28 kWh receives 60%, and 28 to 50 kWh receives 15%. The STC factor steps down again on 1 January 2027 and every six months until the program closes in 2030, so installing sooner secures a larger discount.

Sustainable Household Scheme Battery Component
The ACT Sustainable Household Scheme provides interest-free loans of up to $15,000 for battery storage systems. While not a direct rebate, the zero-interest financing significantly reduces the effective cost of battery ownership. This can be combined with the federal rebate.
