Check your battery quote

The Cheaper Home Batteries Program pays small-scale technology certificates (STCs). A battery gets 6.8 certificates per kWh of usable capacity for the first 14 kWh, 60% of that from 14 to 28 kWh, and 15% from 28 to 50 kWh. The factor drops to 5.7 on 1 January 2027, so the same battery gets less after that date. The date on the battery's electrical safety certificate decides which factor applies, not the date you sign a contract. Your installer claims the certificates and takes their value off the price. The government clearing house pays $40 per certificate before GST, which is why each figure says "up to": certificates also trade on a market, usually for less. Rules checked 28 September 2026.

The Clean Energy Regulator's small-scale installation postcode data, which counts every battery that has claimed small-scale technology certificates since July 2025. August 2026 is provisional: installers have up to twelve months to claim, so the latest month always rises later.
