The federal Cheaper Home Batteries discount does drop on 1 January. This is education only, and it is a national program, not a WA rebate.
The numbers
The discount is based on certificates per kilowatt hour of usable battery capacity. The Clean Energy Regulator publishes these factors: [1]
- May to December 2026: 6.8 certificates per kWh
- 1 January to 30 June 2027: 5.7 per kWh
- 1 July to 31 December 2027: 5.2 per kWh
On a 13 kWh battery that is about 88 certificates now and about 74 from 1 January. At the Clean Energy Regulator clearing house price of $40 a certificate, excluding GST, [3] the difference is about $560 in certificate value. This is an illustration only. Actual prices and eligibility vary.
Two things to know
- The installation date decides which factor applies, not the date a contract is signed. [2]
- The discount does not end on 1 January. The published schedule steps down again from July 2027. [1]
When comparing quotes, ask for the real installation date and compare the price before and after the discount.
