The Australian Government’s Cheaper Home Batteries Program may reduce the upfront cost of an eligible home battery in 2026 through Small-scale Technology Certificates (STCs). The value is not a fixed rebate: it can vary with the battery system, installation details, location, certificate settings and market conditions, and eligibility is determined under the program rules. State or territory incentives may also be available, but they have separate requirements and funding limits. Check the Clean Energy Regulator and energy.gov.au, then ask an accredited battery installer for an itemised quote and confirmation of eligibility.
