Heat Pump Hot Water Rebate Australia 2026: Every State Compared

You can get $800–$1,200 off a heat pump hot water system through federal STCs alone. In Victoria, that combined saving climbs to $1,500–$2,200 or more. Here is every rebate available across Australia in 2026, how each one works, and how to stack them for the maximum discount.

Federal Rebate: STCs (Small-Scale Technology Certificates)

The federal Small-scale Technology Certificate scheme is the foundation of every heat pump rebate in Australia. It applies to all states and territories regardless of what state programs are available where you live.

How STCs work

STCs are certificates created by your CEC-accredited installer at the point of installation. Each certificate represents a megawatt-hour of clean energy your system will displace over its rated life. The installer assigns these certificates to a registered agent, who purchases them, and passes the value back to you as a reduction in your quoted price. You do not fill in forms, submit applications, or wait for a rebate payment — the discount appears directly in your installation quote.

What is the STC rebate worth?

For heat pump hot water systems, the STC rebate typically falls between $800 and $1,200 for most models in most Australian climate zones (Zone 3). The exact value depends on:

• Your postcode and climate zone — warmer zones (Zone 4, northern QLD) receive more STCs; cooler zones (Zone 2, southern VIC and TAS) receive fewer
• The current STC spot price (approximately $38 per certificate in early 2026)
• The rated output and capacity of the specific model installed

Eligibility requirements

• The model must appear on the Clean Energy Regulator’s approved product list
• Minimum capacity of 160 litres
• Minimum 4-star rating under the applicable scheme
• Installed by a licensed plumber — CEC accreditation is standard across the industry

Nationwide access

Every Australian household is eligible for STCs when installing a qualifying heat pump. This is the baseline rebate across all eight states and territories.

State-by-State Heat Pump Rebates

Victoria — VEU Program ($700–$1,000+)

Victoria operates the most active and valuable state-level heat pump rebate in Australia through the Victorian Energy Upgrades (VEU) program.

The VEU program provides rebates of $700 to $1,000 or more for eligible heat pump hot water upgrades that replace gas or electric storage systems. The rebate amount depends on the eligible upgrade activity listed in the VEU activity schedule, as well as the model installed. Because the program is administered through accredited VEU providers, you do not deal with the rebate directly — your installer handles all paperwork and applies the discount at the point of installation.

Key facts:

• Applies when replacing gas hot water or electric storage with a heat pump
• Delivered by accredited VEU providers — not all installers qualify, so confirm accreditation before booking
• No separate application by the homeowner
• Program is well-funded and actively processing claims as of March 2026
• Check the current VEU activity list before purchasing to confirm the specific upgrade activity and rebate amount

New South Wales — Energy Savings Scheme ($200–$600)

NSW households can access the Energy Savings Scheme (ESS), which provides energy saving certificates for eligible hot water upgrades. The value varies by activity and current certificate pricing but typically falls in the range of $200 to $600 for a heat pump hot water installation.

Like the Victorian VEU, the ESS is administered through accredited providers. Your installer will apply for certificates on your behalf and pass the value through as a discount. Not every NSW installer is ESS-accredited, so confirming this before requesting quotes is important.

Key facts:

• Value is lower than the Victorian VEU program but still meaningful when stacked with federal STCs
• Applied at installation by an ESS-accredited provider
• Stacks with federal STCs for a combined $1,000–$1,800 saving

Queensland — Federal STCs Only

Queensland does not currently operate a specific state-level heat pump hot water rebate program in 2026. Queensland residents access federal STCs ($800–$1,200) as their primary incentive. Some local councils and individual energy retailers have offered targeted programs in the past — check with your installer or local council before purchasing, as these programs can emerge and close without wide publicity.

South Australia — Home Energy Efficiency Scheme ($300–$600)

South Australia’s Home Energy Efficiency Scheme provides rebates for eligible hot water upgrades, typically in the range of $300 to $600 for heat pump installations. Rebates are applied through ESCOSA-approved providers — confirm your installer holds the relevant accreditation when requesting quotes.

When stacked with federal STCs, SA buyers can access a combined $1,100–$1,800 in rebates on a typical installation.

---

Australian Capital Territory — Interest-Free Loans

The ACT’s Next Gen Energy Storage program includes hot water upgrades as an eligible measure. Rather than a direct rebate, the program provides interest-free loans for eligible electrification upgrades including heat pump hot water systems. This allows ACT residents to cover the cost of installation with zero interest, repaid through their electricity account over time.

When combined with federal STCs (which reduce the upfront cost before the loan is applied), ACT residents can access a heat pump with minimal or no out-of-pocket expenditure at the time of installation.

Western Australia — Federal STCs Only (in Most Cases)

Western Australia does not currently operate a state-level heat pump hot water rebate program applicable to most residential customers. Synergy and Horizon Power customers should check directly with their retailer for any current targeted programs, as retailer-specific incentives can exist outside of formal state government schemes. Federal STCs are the main incentive available to WA households.

Tasmania — Federal STCs Only

Tasmania has no active state-level heat pump rebate program. Federal STCs apply as they do nationally.

Stacking Rebates: Maximum Savings by State

The federal STC rebate and state-level rebates are entirely separate incentives. Where both exist, they can be applied to the same installation — effectively stacking the discounts.

State	Federal STCs	State Rebate	Total Saving
VIC	~$1,000	~$1,000 (VEU)	~$2,000+
NSW	~$1,000	~$400 (ESS)	~$1,400
SA	~$1,000	~$450	~$1,450
QLD	~$1,000	None	~$1,000
ACT	~$1,000	0% loan	$1,000 + financing
WA	~$1,000	None	~$1,000
TAS	~$1,000	None	~$1,000
NT	~$1,000	None	~$1,000

STC values are estimates for Zone 3. Actual amounts depend on climate zone, model, and current STC spot price.

Worked example — Victoria

A Solahart Atmos Eco 280L has a supply price of approximately $3,500. In Victoria:

• Federal STCs: approximately $1,000 discount
• VEU rebate: approximately $1,000 discount
• Effective supply cost after rebates: approximately $1,500
• Installation (labour, plumbing connections, removal of old unit): $600–$900 depending on site complexity
• All-in cost: approximately $2,100–$2,400

Without rebates, the same installation would cost $4,100–$4,400. The combined rebates reduce the total cost by roughly 45–50%.

How to Claim Your Heat Pump Rebate

The process is straightforward because most of the work is handled by your installer. The key is choosing the right installer and confirming the right details before signing a quote.

Step 1: Get two or three quotes from CEC-accredited installers

CEC accreditation ensures the installer is eligible to create STCs on your behalf. Most reputable heat pump installers hold this accreditation — confirm it when contacting them.

Step 2: Confirm the model is on the CEC approved product list

Not all heat pumps qualify for STCs. Before committing to a specific model, check that it appears on the Clean Energy Regulator’s approved product list. Your installer should be able to confirm this, but it is worth verifying independently.

Step 3: Ask each installer to confirm STCs and any state rebates are included in the quote

A compliant quote should clearly show the rebate being applied as a line-item discount. If an installer presents a price without mentioning STCs, ask specifically. Some installers pocket the STC value rather than passing it on — this is a red flag.

Step 4: For Victoria — confirm VEU accreditation

Not every Victorian installer is accredited under the VEU program. Ask specifically: “Are you a VEU-accredited provider?” before booking. If they are not, you will miss the $700–$1,000+ state rebate.

Step 5: For NSW — confirm ESS accreditation

Similarly, confirm that your NSW installer holds ESS accreditation to ensure the state rebate is applied to your quote.

Step 6: Pay the discounted price at installation

Once installed, no further action is required. The rebates have been applied, the installer claims the certificates, and you have received the benefit through the reduced price you paid.
