Eligible hot-water upgrades
Federal STCs
NSW Energy Savings Scheme (ESS)
Discounts depend on the existing system, product, installation and participating provider. Eligibility must be checked before work starts.
South Australia
Federal STCs and eligible REPS provider offers may be available. Amounts and availability depend on the provider and installation.
QLD / WA / TAS / NT / ACT
Federal STCs are available nationally for eligible systems. Check local programs and their separate conditions.
Before you buy: Buying equipment alone does not guarantee a rebate. Eligibility depends on your location, exact model, system configuration, installation date, installer or retailer accreditation and scheme rules. Required approvals and nomination forms must be completed before installation, except where an official emergency process applies. Your quote should identify each incentive and any remaining installation costs.
These hot-water incentives relate to eligible domestic hot-water systems, not pool-heating products.
Rebate Programs Explained
Eligible heat pump hot-water installations can earn Small-scale Technology Certificates (STCs) under the federal Small-scale Renewable Energy Scheme. You may assign the right to create STCs to a registered agent in exchange for a discount, or retain that right and arrange their creation and sale yourself. Certificate quantity and the dollar discount are different: the discount depends on the agreed certificate price and any fees.
| Estimated number of STCs — 2026 installations | ||||||
|---|---|---|---|---|---|---|
| Model | Zone1 | Zone2 | Zone3 | Zone4 | Zone5 | |
| PBG2-200RE-HYBRID | 13 | 13 | 16 | 17 | 17 | |
| PBG2-300RE-HYBRID | 13 | 13 | 16 | 17 | 16 | |
Estimated STC quantities for installations in 2026. The table uses the CER register values for the exact listed models, multiplied by the 2026 factor of 0.5 and rounded down. Quantities depend on the installation postcode zone and installation year; they are not dollar amounts or confirmation of an approved claim.
Both models are currently listed under Power Bay in the CER register. Check current listing dates and installation requirements before proceeding.
The Victorian Energy Upgrades (VEU) program can reduce the cost of replacing an eligible inefficient hot-water system. Accredited providers create Victorian Energy Efficiency Certificates (VEECs) for eligible upgrades and use their value to offer discounts. VEECs are tradable certificates, not a fixed cash rebate paid directly by the government to each household.
Certificate quantities depend on the approved product, installation postcode and replacement activity. Ask your accredited provider for a current calculation and written quote; a metro or regional label alone is not enough to determine an entitlement.
For current eligibility and participating providers, see Victorian Energy Upgrades hot-water discounts. Discounts vary with the installation and provider offer. Model-specific VEEC quantities must be verified before a quote is finalised.
Eligible owner-occupiers may receive a Solar Victoria hot-water rebate. It covers 50% of the eligible product price after other discounts, including STCs and VEECs, capped at $1,000 for eligible products or $1,400 for products specifically listed under the locally made incentive. The higher amount does not apply to every brand or model.
Use an authorised hot-water retailer and a product on Solar Victoria’s current eligible list. Obtain approval and your QR code before installation, except when the official emergency-installation process applies. The rebate is paid to the retailer and deducted from your invoice.
For applications from 1 July 2026, the general eligibility conditions include:
- You are the owner-occupier of an existing property where the system is to be installed.
- The household taxable income of all owners combined is less than $150,000 per year.
- The value of the property is under $3 million.
- the property address has not already received a hot water or a solar battery rebate under the Solar Homes Program.
- The hot water system to be replaced is at least 3 years old from the date of purchase.
- You received a Solar Homes rebate and/or loan but have moved house. You can apply for another incentive at your new address as an owner-occupier if the property has not received these rebates before.

Eligible NSW households and small businesses may receive an upfront discount through the Energy Savings Scheme (ESS). The installer must work with an Accredited Certificate Provider (ACP). The offer depends on the existing water heater, approved replacement product and installation circumstances; it is not a fixed statewide cash rebate.
Complete the nomination form before installation. A customer payment is required, and the written quote should show the discount and total installation cost. Eligible heat-pump products must meet the scheme’s warranty and equipment requirements, including a minimum five-year defects warranty covering the unit, tank and supplied components.
See the NSW hot-water upgrade incentive. A separate enhanced discount in selected postcodes is available until June 2027 or funding exhaustion, subject to its own conditions.
South Australia’s Retailer Energy Productivity Scheme (REPS) supports eligible energy-saving upgrades through participating retailers and activity providers. Hot-water offers depend on provider availability, the existing system and the proposed upgrade. Discounts are assessed by participating providers rather than a fixed statewide amount.
Ask the provider to confirm eligibility, available discounts and any costs before work begins. Federal STCs may also be available when the installation meets their separate requirements. See REPS water-heating activities and providers.
Rebate Programs Explained
Last reviewed: 12 September 2026. The Cheaper Home Batteries Program provides a certificate-based discount for eligible battery installations. For systems certified for electrical compliance from 1 May to 31 December 2026, the STC factor is 6.8: 100% applies to the first 14 kWh of usable capacity, 60% to the portion above 14 up to 28 kWh, and 15% above 28 up to 50 kWh. Add the tier amounts, then round down.
The next scheduled factor change is 1 January 2027. The compliance date, not the purchase or deposit date, determines the applicable rate. See CER calculation guidance.
| Battery | Estimated STCs — 1 May–31 December 2026 |
|---|---|
| ASW5120-LB-G3 5.12KWH | 34 |
| ASW5120-LB-G3 10.24KWH | 69 |
| ASW5120-LB-G3 20.48KWH | 121 |
| Ai-HB 100A | 62 |
| Ai-HB 200A | 113 |
Calculation assumptions: The three ASW5120-LB-G3 rows represent one, two and four modules using 5.12 kWh usable capacity per module. Ai-HB 100A uses 9.21 kWh and Ai-HB 200A uses 18.43 kWh. These are the values in the CER-hosted CEC register dated 2 September 2026. Counts are estimates for an eligible installation, not dollar discounts or approved claims. See the official battery register.
Listing dates: That register lists Ai-HB 100A and 200A as expiring on 9 October 2026. Eligibility for later installations must be checked against an updated listing; renewal is not guaranteed.
Federal eligibility includes a new listed battery of 5–100 kWh nominal capacity, installed with eligible new or existing solar PV by an appropriately SAA-accredited installer. STCs cover up to the first 50 kWh usable capacity. Only one battery STC claim is available per premises; later additions cannot receive another claim. Grid-connected systems must be VPP-capable, but the federal program does not require joining a VPP. Check the full CER eligibility conditions.
The agreed net STC price and fees determine the discount. Your quote must show the incentive and remaining costs separately. Buying a battery alone does not guarantee eligibility.
The WA Residential Battery Scheme may provide up to $1,300 for eligible Synergy customers or $3,800 for eligible Horizon Power customers, calculated on usable capacity up to 10 kWh. It may combine with federal battery support when both schemes’ conditions are met.
Use an approved scheme vendor and equipment on the relevant Synergy or Horizon Power supported-solutions list as well as the CEC list. VPP participation is required. No-interest loans have separate eligibility, income and lending conditions. PowerBay product eligibility must be checked for the exact battery/inverter combination before purchase.
See WA scheme eligibility and current requirements.
3. NSW virtual power plant incentive
Eligible NSW households may receive an incentive for connecting a battery to a participating VPP. From 1 July 2026, batteries up to 50 kWh may qualify; the incentive calculation is capped at 28 kWh of eligible capacity. Actual amounts vary by provider and contract. Check model compatibility, retailer requirements and the one-claim-per-NMI rule before committing.
This can combine with federal battery support when both schemes’ conditions are satisfied. See the current NSW VPP incentive.
Rebate Programs Explained
Last reviewed: 12 September 2026. Eligible solar PV installations can earn federal STCs. The number depends on the installed panel capacity, postcode rating and installation year. For 2026 installations, the maximum deeming period is five years. A dollar discount is calculated from the eligible certificate count and the agreed net price per STC, including any administration fees; there is no fixed national $1,600 rebate.
For example, a 6.60 kW system in Sydney postcode 2000 installed in 2026 produces an estimated 45 STCs. The discount depends on the STC price in your quote. The table below deliberately uses 6.66 kW, 10.12 kW and 13.20 kW examples; use your actual installed capacity when calculating your own entitlement.
| Estimated number of STCs — 2026 installations | |||
|---|---|---|---|
| 6.66KW | 10.12KW | 13.20KW | |
| Sydney 2000 | 46 | 69 | 91 |
| Melbourne 3000 | 39 | 59 | 78 |
| Brisbane 4000 | 46 | 69 | 91 |
| Perth 6000 | 46 | 69 | 91 |
| Adelaide 5000 | 46 | 69 | 91 |
| Canberra 2600 / 2601 | 46 | 69 | 91 |
| Hobart 7000 | 39 | 59 | 78 |
| Darwin 0800 | 51 | 77 | 101 |
Estimated STC quantities for 2026 installations. These examples use the stated panel capacities, postcode ratings and five-year deeming period, rounded down. They are certificate counts, not dollar rebates or approval of an individual claim.
Eligibility requires the exact approved panels and inverter configuration, compliant installation and an appropriately SAA-accredited installer. Your quote should show the system price, any STC assignment, net certificate discount and remaining costs. Buying panels alone does not guarantee an incentive. Check CER calculation guidance and the current product listings before proceeding.
Eligible Victorian households may receive a solar PV rebate of up to $1,400 and an optional interest-free loan matching the rebate amount. Eligible federal STC discounts may also apply. The loan is repayable and is not an additional rebate.
General owner-occupier conditions include combined taxable income of all owners below $150,000 per year, property value under $3 million, no previous Solar Homes solar PV or battery rebate at the address, and no solar PV system installed there in the last ten years. Separate pathways apply to eligible rental properties and homes under construction.
Use an authorised Solar Victoria retailer, panels and inverters on its eligible lists, and appropriately accredited installers. Obtain Solar Victoria eligibility approval and your QR code before installation; installing first makes the installation ineligible for this rebate. Grid-connection approval may also be needed.
See Solar Victoria’s full PV rebate conditions and eligible products. Your retailer must confirm eligibility and the final discount for your circumstances.
