How the Cheaper Home Batteries Program (CHBP) Works in Queensland

The Cheaper Home Batteries Program (CHBP) is a federal incentive that brings down the upfront cost of an eligible home battery. It uses the same Small-scale Technology Certificate (STC) machinery that already discounts solar panels — applied to batteries instead. If you’re adding a battery to a new or existing solar system in Queensland, the CHBP almost certainly applies.

This post covers what the CHBP is, how the rebate is calculated, the 1 May 2026 step-down, the schedule of further step-downs through 2030, and how we apply the rebate inside a Prestige Power & Energy quote.

What the CHBP actually is

The CHBP isn’t a cash-back scheme. It’s an STC scheme — your battery generates a number of certificates at installation time, and we (the installer) take assignment of those certificates and apply their market value as a discount on your quote. You don’t claim the rebate yourself, and you don’t receive a separate payment. The discount comes off the price of the system at the point of sale.

The amount depends on three things:

• Battery capacity (kWh) — bigger battery, more STCs.
• The CHBP factor for the current period — set by the federal Clean Energy Regulator. This is the part that steps down on a fixed schedule.
• The current STC spot price — what STCs are trading for on the open market. This fluctuates weekly.

The tiered capacity structure

The CHBP factor isn’t flat — it tiers by battery capacity. The three tiers are:

• 0 – 14 kWh — the standard residential range. Most single-home installs fall here.
• 14 – 28 kWh — larger residential, often paired with EV charging or pool loads.
• 28 – 50 kWh — light-commercial or premium residential. Rare in single-home installs.

Each tier earns STCs at a different rate per kWh. The 0–14 tier is the most generous on a per-kWh basis; the higher tiers earn less per incremental kWh, which is intentional — the scheme is designed to reward whole-home electrification at typical residential sizing, not to subsidise outsized commercial systems.

What changed on 1 May 2026

The CHBP factor stepped down on 1 May 2026 — the first scheduled reduction since the program launched. The next step-down is locked in for 1 November 2026, with further step-downs scheduled every six months through 2030.

What this means practically:

• A battery installed in April 2026 earned more STCs than the same battery installed in May 2026. The hardware didn’t change; the factor did.
• The CHBP rebate is locked in at install completion, not at contract date. This is critical: if your contract is signed in late October but install slips to November, you fall into the next step-down period. The ACCC has flagged the contract-vs-completion confusion as a misleading-conduct vector under Australian Consumer Law § 18 — any installer quoting an April rebate for a May install is misrepresenting the scheme.
• The schedule is public and fixed. We confirm the install-completion date in your quote and use the factor that applies on that date, not the contract date.

Eligibility requirements

To qualify for the CHBP rebate, the install needs to meet all of these:

• SAA-accredited installer. All Prestige Power & Energy installs are signed off by Carlos Flynn (SAA-accredited Design & Install classes GCPV, GCBS, SPS) and our crew is NETCC-approved.
• Approved Product List (APL) battery. The battery model has to be on the Clean Energy Regulator’s APL. We only quote APL-listed units; the major brands we install — Goodwe, Sungrow, Sigenergy — are all approved.
• Connected to a solar PV system. The CHBP isn’t a stand-alone battery rebate. The battery has to be paired with a solar system (either new or existing). If you have existing solar, we confirm the system is compatible during the design phase.
• Australian residential property. Investment properties generally qualify if the meter is residential. We check this at quote time.

How we apply the rebate in your quote

At Prestige, the CHBP rebate is itemised line-by-line in your quote — not buried in a single “after rebate” figure. You see the gross system cost, the STC component for solar (if applicable), the CHBP component for the battery, and the final price. This isn’t us being unusually transparent; the ACCC ratification on Australian consumer law says lumped “save $X” displays are misleading conduct. Every rebate has to be substantiated per customer, on the actual quote PDF, with the factor and install date that apply to you.

When you accept the quote, we take assignment of the STCs at install completion and the discount flows through to your invoice automatically.
