Cheaper Home Batteries Program

What changes on 1 January 2027.

The federal discount is based on the battery’s installation date. Here is the short version.

6.8 to 5.7

The STC factor drops from 6.8 now to 5.7 from 1 January 2027. That is about a 16% lower factor, not a 16% rise in battery prices.

Jan and Jul

The factor steps down every six months, each January and July.

By size

The full factor applies up to 14kWh. From 14kWh to 28kWh it is 60% of the factor.

With solar

The battery must be installed with new or existing solar PV. Other eligibility requirements apply.

The rate that applies depends on your installation date and eligibility. Ask us about available installation dates. Full details on the official Cheaper Home Batteries page.
