Is there a rebate for a home battery?

The short answer

Yes. The federal Cheaper Home Batteries Program discounts around 30% of the upfront cost of batteries from 5 kWh to 100 kWh, with the discount tapering above 14 kWh since 1 May 2026.

The Cheaper Home Batteries Program is a federal discount on small-scale battery systems, delivered the same way the solar discount is: through Small-scale Technology Certificates that the installer assigns, appearing as a reduction on your quoted price rather than a payment you claim.

It targets roughly a 30% discount on the upfront cost of eligible systems between 5 kWh and 100 kWh. In December 2025 the government expanded the program from an estimated $2.3 billion to an estimated $7.2 billion over four years.

How the tapering works

Two changes took effect on 1 May 2026. The discount calculation was adjusted to track falling battery costs, and the certificate factor now tapers with installed capacity rather than applying flat:

Installed capacityCertificate factor applied
0 kWh up to and including 14 kWh100%
Above 14 kWh up to and including 28 kWh60%
Above 28 kWh up to and including 50 kWh15%

The practical effect is that the support is concentrated on battery sizes typical of a household rather than on very large installations. The actual dollar value still depends on the market price of certificates at the time, so it is not a fixed figure.
