Australian homeowners in New South Wales and Victoria have an unprecedented opportunity in 2026 to significantly reduce the upfront cost of major energy-efficient home upgrades. By strategically combining federal and state government incentives, you could save up to $15,000 or more through a mix of direct rebates, upfront discounts, and zero-interest loans on installations like heat pump hot water systems, EV chargers, solar panels, and home batteries.
This guide cuts through the complexity, providing clear, actionable steps and current 2026 figures to help you maximise your savings. The optimal time to electrify is now, as many incentives are designed to phase out as adoption increases.
Understanding Federal & State Rebates
Most energy-efficient home upgrades in Australia benefit from a combination of federal and state-specific programs. The cornerstone of federal support is the Small-scale Renewable Energy Scheme (SRES), which awards Small-scale Technology Certificates (STCs) for eligible installations like solar PV, solar hot water, and heat pump systems.
In 2026, STCs typically trade between $37 and $40 each, offering an upfront discount on your system. However, the number of STCs a system earns reduces annually as the scheme winds down towards its 2030 end date.
For home batteries, the federal Cheaper Home Batteries Program provides an upfront discount of approximately $252 per kWh for systems up to 14kWh, reducing for larger systems. This rebate is not means-tested and can be stacked with state incentives.
State governments in NSW and Victoria offer their own powerful incentives, which can be combined with federal STCs and battery rebates to deliver substantial savings.
“Australian homeowners can access $3,000-$15,000+ in government rebates for energy upgrades in 2026. Key programs include: Solar Victoria (up to $1,400 + $8,800 interest-free loan), Victorian Energy Upgrades for heat pumps and insulation, federal STCs for solar and hot water, and the federal Household Energy Upgrades Fund.”
New South Wales: Stacking Savings
NSW homeowners have access to a robust suite of incentives designed to accelerate the transition to an all-electric home.
Heat Pump Hot Water Systems
NSW offers a combination of federal STCs and the state’s Energy Savings Scheme (ESS) for heat pump hot water upgrades. The ESS provides an upfront discount:
- Up to $640 when replacing an electric water heater with a heat pump.
- Up to $330 when replacing a gas water heater with a heat pump.
Combined with federal STCs, which can be worth approximately $490 to $680 depending on the system and climate zone, the total upfront discount can range from $900 to $1,350.
For instance, a premium Reclaim Energy CO2 315L heat pump might cost $6,600 - $8,000 installed before rebates. After federal STCs and the ESS discount, the out-of-pocket expense could be reduced to approximately $4,320 - $6,620.
EV Charger Installation
While there is no standalone direct rebate for residential EV charger installations in NSW as of 2026, the NSW Home Energy Saver program provides a significant pathway to affordability. This program offers zero-interest loans of up to $15,000 repayable over 10 years, which can be used for eligible energy-saving upgrades, including Level 2 EV chargers.
Additionally, targeted discounts of up to $4,000 will be available later in 2026 for lower-income households (combined income under $80,000) or those with an eligible concession card. This means the cost of an EV charger, typically $1,500 - $3,000 installed for models like the Zappi or Wallbox Pulsar Plus, can be covered by the loan or reduced further by the discount for eligible households.
Solar & Batteries
NSW residents can combine federal STCs for solar with the federal Cheaper Home Batteries Program and the NSW Home Energy Saver loan:
- Federal Solar STCs: Approximately $1,800 for a typical 6.6kW system.
- Federal Battery Rebate: Around $252 per kWh, potentially $3,367 for a 13.5kWh battery.
- NSW Home Energy Saver Loan: Up to $15,000 zero-interest loan to cover the remaining costs after federal rebates.
This means a household installing a 6.6kW solar system and a 13.5kWh battery, with an estimated gross cost of $14,000 - $18,000, could see thousands off the upfront price from federal incentives, with the remainder covered by a zero-interest loan.
Victoria: Maximising Your Upgrades
Victoria continues to be one of Australia’s most supported states for home energy upgrades, offering a range of stackable incentives.
Heat Pump Hot Water Systems
Victorian households can stack federal STCs, the Victorian Energy Upgrades (VEU) program, and the Solar Homes Program hot water rebate.
- Federal STCs: Approximately $490 to $680, reducing the upfront cost.
- VEU Discount: Between $560 and $910 (or more for specific replacements), provided as an upfront discount by accredited installers.
- Solar Homes Hot Water Rebate: Up to $1,000 for eligible heat pump systems, or up to $1,400 for eligible Australian-made systems (e.g., Reclaim Energy models). This is a 50% rebate on the purchase price, capped at these amounts, and is applied after other discounts.
To qualify for the Solar Homes hot water rebate, the combined household taxable income must be under $150,000 per year from 1 July 2026 (previously $210,000), and the property value must be under $3 million. The system must replace an existing hot water system that is at least three years old.
By stacking these, total upfront savings can reach up to $2,030 for standard systems or up to $2,700 for Australian-made systems. For example, a Reclaim Energy Eco (R290) heat pump, starting around $4,900 installed before rebates, could see significant reductions.
EV Charger Installation
As of 2026, there is no direct state-level residential EV charger rebate specifically for Victorian homeowners. While federal programs like DRIVEN target businesses, individual households generally bear the full cost of home charger installation, which typically ranges from $800 to $3,000.
However, pairing an EV charger with a solar system allows for cheaper charging through self-consumption of solar energy. For strategies on optimising your home energy setup, consider exploring guides like Best Home Energy Management Systems in Australia 2026: Slash Bills by $1,000+ Annually.
Solar & Batteries
Victoria’s Solar Homes Program is a key incentive for solar PV and hot water, though the separate battery loan program has closed.
- Solar Homes PV Rebate: Up to $1,400 off the cost of installing a solar panel system, with an optional interest-free loan of up to $1,400.
- Federal Battery Rebate: Eligible systems receive approximately $252 per kWh upfront discount.
Remember the income eligibility change for the Solar Homes Program: from 1 July 2026, the combined household income cap is $150,000.

Practical Steps to Claim Your Rebates
- Check Eligibility: Each program has specific criteria (income, property type, existing system age). Visit official state government websites (e.g., energy.nsw.gov.au, solar.vic.gov.au) to confirm your eligibility.
- Find Accredited Providers: Most rebates and discounts are applied directly by accredited installers at the point of sale. Ensure your chosen installer is approved under the relevant schemes (e.g., Clean Energy Council for STCs, Solar Victoria for Solar Homes).
- Get Multiple Quotes: Compare quotes from several accredited providers. Ensure the quotes itemise the rebates and discounts clearly.
- Apply for Loans First (NSW): For the NSW Home Energy Saver loan, apply through approved finance providers like Brighte or Plenti before finalising your installer and products.
- Understand Stacking Order: Federal STCs and VEU/ESS discounts are typically applied first, reducing the upfront cost, before any state rebates (like Solar Homes hot water rebate) or loans cover the remaining balance.

Bottom Line
In 2026, homeowners in NSW and Victoria can achieve substantial savings on major energy upgrades by diligently stacking available federal and state government incentives. You could realistically reduce the net cost of a new heat pump hot water system to under $2,000 in NSW (with the Home Energy Saver loan/discount) or around $2,700-$4,500 in Victoria. For EV chargers, the NSW Home Energy Saver zero-interest loan offers a clear path to affordability, covering the full installation cost for many. While Victoria lacks a direct residential EV charger rebate, integrating charging with existing or new solar can still lead to significant running cost savings. The key is to act promptly, as rebate values and eligibility criteria are subject to change and often diminish over time. Engage with accredited installers to ensure all applicable incentives are factored into your upfront cost.
