Updated 10 October 2026: re-checked against ACT Climate Choices. An earlier version said the $15,000 cap and product coverage were unchanged. Both have changed: the maximum is now $20,000, and rooftop solar on its own is no longer on the eligible list.
The ACT Sustainable Household Scheme is a low-interest loan, not a rebate. It charges 3% interest, with no upfront costs or fees, repaid over up to 10 years.
What it covers now
- Loans of $2,000 to $20,000. Households that were in the scheme, or applied or were approved, before 1 July 2026 stay capped at $15,000 over the life of the scheme.
- Eligible products include household battery storage, heat pump and evacuated tube hot water, electric heating and cooling, electric stove tops, EVs and chargers, ceiling insulation and electric cargo bikes.
- Rooftop solar on its own is no longer eligible. Loans for solar are now only available to eligible concession card holders, through the Home Energy Support Program.
What 3% costs
On the maximum $20,000 over 10 years at 3%, the repayment is about $193 a month and the total interest about $3,175, or about $26 a month more than an interest-free loan of the same size. This is general information, not financial advice; we don't arrange or recommend credit.
Other ACT support
- Home Energy Support Program, for concession card holders: up to $5,000 in rebates, covering up to half the cost of upgrades including rooftop solar, plus a zero-interest loan of up to $10,000.
- Federal STCs and the Cheaper Home Batteries discount stack on top: about $1,784 on a 6.6 kW system in Canberra and about $3,608 off a 13.5 kWh battery, at the 15 October 2026 price of $39.65 per STC.
