NT & ACT Hot Water Rebates 2026: Heat Pump
ACT & Northern Territory Hot Water Rebates 2026
ACT households can access some of Australia's strongest targeted electrification support, while NT hot-water incentives are mainly federal STCs plus a local Alice Springs solar-hot-water subsidy.
The two territories have very different support structures. In the ACT, eligible concession homeowners may access a direct rebate for heat-pump or evacuated-tube solar hot water and other households can use the Sustainable Household Scheme. In the NT, there is no broad territory-wide hot-water cash rebate verified for 2026, but eligible heat pumps and solar water heaters can still receive federal STCs and Alice Springs has a local solar-hot-water subsidy.
What Could Apply to Me?
Use this as a preliminary pathway only. Final eligibility must be confirmed with the relevant scheme, approved supplier, installer or council before purchase or installation.
Installed Today does not guarantee government, council or certificate eligibility. ACT programs can require eligible homeowners, concession status, approved products and approved suppliers. Alice Springs conditions and funding can change. Federal STCs require an eligible registered system installed in the approved configuration.
ACT & NT Hot Water Rebates: The Quick Answer
Both territories can access federal Small-scale Technology Certificates for eligible heat-pump and solar hot-water systems. The ACT then adds substantial local support, while the Northern Territory currently relies mainly on STCs except for a local Alice Springs solar-hot-water subsidy.
Federal STCs Apply in Both the ACT and NT
Eligible air-source heat pumps and solar water heaters can create federal STCs when the exact model is listed on the Clean Energy Regulator register and the installation is completed in the approved configuration.
Heat Pump Hot Water
Eligible registered air-source heat pumps can create STCs. The exact certificate entitlement depends on the model, installation date and geographic zone.
Solar Hot Water
Eligible registered solar water-heater systems can also create STCs. The listed tank, collectors and system configuration must match the approved model.
Not a Fixed Cash Rebate
STCs are tradable certificates. They are often assigned to a registered agent in return for an upfront discount, so the dollar value can vary.
ACT Home Energy Support Program: Up to $2,500 for Hot Water
Eligible ACT homeowners with an approved concession card can receive 50% of the total supply-and-installation cost, up to $2,500, for approved energy-efficient upgrades including hot-water heat pumps and evacuated-tube solar hot-water systems.
Who Is It For?
The program is targeted to eligible ACT homeowners who hold an Australian Government Pensioner Concession Card, Department of Veterans' Affairs Gold Card or Australian Government Health Care Card, subject to current program rules.
How Much?
For the relevant energy-efficiency category, the rebate is 50% of eligible supply and installation costs up to $2,500. Separate rooftop-solar support can take total Home Energy Support rebates to as much as $5,000 for eligible participants.
Which Hot Water Systems?
The current hot-water pathway includes approved hot-water heat pumps and evacuated-tube solar hot-water systems. Standard resistance electric and conventional gas hot water are not the focus of this rebate.
ACT Sustainable Household Scheme: Finance Can Sit Beside the Rebate
The ACT also has a finance pathway for approved energy-efficient upgrades, including hot-water heat pumps and evacuated-tube solar hot water.
General Eligible Households
For new applicants approved from 1 July 2026, eligible households can borrow from $2,000 up to $20,000 at 3% interest, with no establishment or account-keeping fees and repayment terms up to 10 years.
Home Energy Support Participants
Eligible households approved for Home Energy Support may be able to combine their rebate with up to $10,000 in zero-interest Sustainable Household Scheme finance.
Approved Products & Suppliers
The scheme has eligibility, product and supplier requirements. Customers should confirm the approved pathway before ordering or beginning installation.
Northern Territory Hot Water Rebates in 2026
For most NT households, federal STCs remain the main broad hot-water incentive verified for 2026. A separate broad NT Government heat-pump or solar-hot-water purchase rebate was not identified in the current official programs reviewed for this page.
Heat Pump
Eligible registered heat pumps can receive federal STCs. There is no broad NT-wide heat-pump cash rebate verified for ordinary households at the time of this review.
Solar Hot Water
Eligible solar hot-water systems can receive federal STCs. Alice Springs residents may also have access to a separate local council subsidy.
Energy Concessions
NT electricity concessions and bill-relief programs may reduce household energy costs, but they should not be confused with a dedicated heat-pump or solar-hot-water purchase rebate.
Alice Springs Green Living Subsidy: Solar Hot Water Only
Alice Springs Town Council currently offers a local Green Living Subsidy for residential solar hot water. This is a council program, not an NT-wide rebate.
Subsidy Amount
The current offer is 50% of the purchase price up to $300 for an eligible residential solar hot-water system.
Local Purchase Rule
From 1 September 2026, the solar-hot-water subsidy applies to systems purchased from or sourced through a local Alice Springs plumber or business.
Not for Heat Pumps
The Green Living Subsidy specifically lists residential solar hot-water systems. Heat-pump hot water should rely on the federal STC pathway unless another eligible program applies.
ACT vs NT Hot Water Incentives - 2026

Supply Only vs Supplied & Installed
The product can be eligible while the final claim still fails if the installer, supplier, approval sequence or installation does not satisfy the relevant program.
Supply Only / Own Installer
Confirm the exact model, installer licensing, STC agent and any ACT or Alice Springs program requirements before purchase. A supply-only order does not automatically complete any rebate, loan or certificate claim.
- Check the model's current STC registration.
- Confirm any approved-supplier requirement.
- Check whether approval must occur before installation.
- For Alice Springs, confirm the local-purchase rule before ordering.
Supplied & Installed Where Available
Review the installed package carefully and confirm which incentives are included. ACT government programs generally require their own approved supplier and participant pathway, while federal STCs still depend on the registered product and completed installation.
- Do not assume a rebate is included unless shown.
- Site and electrical work can affect final cost.
- Government programs can have separate application steps.
- Keep all installation and eligibility documentation.
How to Check Your ACT or NT Hot Water Incentive Before Buying
Confirm Location
ACT, Alice Springs and the rest of the NT currently have materially different support pathways.
Choose Technology
Most available hot-water incentives focus on eligible heat pumps or solar hot water rather than standard electric or gas.
Check Product & Provider
Confirm the exact registered model and any approved supplier, local business or concession requirement.
Confirm Before Work Starts
Do not assume a rebate can be fixed after installation if pre-approval or a specific provider pathway was required.
ACT & Northern Territory Hot Water Rebate FAQs
What hot water rebate is available in the ACT in 2026?
Eligible ACT concession homeowners can receive 50% of eligible supply and installation costs up to $2,500 for approved upgrades including hot-water heat pumps and evacuated-tube solar hot water. Eligible systems may also receive federal STCs.
Who can get the ACT Home Energy Support hot-water rebate?
The program is targeted to eligible ACT homeowners who hold an approved concession card, including eligible Pensioner Concession Card, Department of Veterans' Affairs Gold Card and Health Care Card holders, subject to current program criteria.
Can ACT households finance a heat-pump hot-water system?
Eligible new applicants under the Sustainable Household Scheme can access loans from $2,000 to $20,000 at 3% interest for approved energy-efficient upgrades including hot-water heat pumps and evacuated-tube solar hot water. Eligible Home Energy Support participants can access a separate zero-interest pathway up to $10,000.
Does the Northern Territory have a heat-pump rebate in 2026?
No broad NT-wide heat-pump cash rebate for ordinary households was verified for this page. Eligible registered heat pumps can still receive federal STCs.
Does Alice Springs have a solar-hot-water rebate?
Yes. Alice Springs Town Council currently lists a Green Living Subsidy of 50% of the purchase price up to $300 for eligible residential solar hot-water systems, subject to current local eligibility and purchase rules.
Can I buy a solar hot-water system online and still claim the Alice Springs subsidy?
Do not assume so. From 1 September 2026, the council's current rules state that the solar-hot-water system must be purchased from or sourced through a local Alice Springs plumber or business.
Are heat pumps and solar hot water eligible for federal STCs in both territories?
Yes, if the exact model is listed on the Clean Energy Regulator register and the completed installation meets the scheme requirements. The certificate entitlement depends on the model, date and geographic location.
Can standard electric or gas hot water receive STCs?
No. Conventional resistance-electric storage and standard gas hot-water systems do not create hot-water STCs. The federal pathway applies to eligible renewable hot-water technologies such as registered air-source heat pumps and solar water heaters.
Is supply-only enough to claim the ACT rebate?
No. ACT rebate and finance programs have their own participant, supplier, product and installation requirements. Confirm the approved pathway before placing a supply-only order.
Which technology should I compare first?
Where the site suits, heat pump should usually be one of the first options compared because it can qualify for federal STCs in both territories and may access substantial additional ACT support. In Alice Springs, solar hot water deserves a stronger comparison because of excellent solar conditions and the current local solar-hot-water subsidy.
Compare the Hot Water System First, Then Confirm the Incentive
ACT and NT support can materially change the upfront cost of an eligible heat-pump or solar-hot-water upgrade, but the system still needs to suit the household, climate, site and installer pathway. Start with the right technology, then confirm the exact rebate, finance or STC process before work begins.
