Cut your cooling costs by up to 40% and secure an upfront government discount on high-efficiency AC upgrades.
What is the NSW Energy Savings Scheme (ESS)?
The NSW Energy Savings Scheme (ESS) is the state’s primary financial pathway for homeowners and property managers to reduce power consumption. Under the Electricity Supply Act 1995, this program provides an upfront discount on energy-efficient air conditioning (AC) systems to help NSW reach its 70% emissions reduction target by 2035.
Why act now?
-
12-Year Rule: As of late 2025, the government increased the calculated efficiency life of AC units, leading to higher available discounts.
-
Net-Zero Alignment: The scheme is now extended to 2050, prioritising long-term sustainability.
The Cost of Inaction: Why Legacy AC Units are Financial Liabilities
Heating and cooling account for 40–50% of your total energy bill. If your unit was installed prior to 2010, you are likely facing:
-
40% Higher Running Costs: Older non-inverter systems run at full capacity constantly.
-
The R22 Crisis: Legacy units use R22 refrigerant, which is environmentally harmful and becoming cost-prohibitive to repair.
-
Modern Solution: Upgrading to an R32-based system offers superior heat transfer and a smaller environmental footprint.
How Much Can You Save?
The ESS discount isn't a rebate you wait for—it is applied directly to your installer's quote.
System Type | Avg Upfront Discount | Estimated Power Savings |
|---|---|---|
Full Ducted Unit Replacement | Max Certificate Value | Up to 40% lower running costs |
New Split System | Up to 20% of install cost | Up to 30% reduction |
Pro Tip: Look for the Zoned Energy Rating Label (ZERL). Higher star ratings generate more Energy Savings Certificates (ESCs), increasing your direct discount.
The Mandatory Rule: Use an ESS-Accredited Installer
You cannot access these discounts through standard retailers. To qualify, you must use an installer partnered with an Accredited Certificate Provider (ACP).
Your Installer Checklist:
-
Verify Accreditation: Ask for their ACP partner name.
-
GEMS Compliance: Ensure they only use products from the Greenhouse and Energy Minimum Standards registry.
-
Mandatory Decommissioning: Your old unit must be legally removed and recycled to comply with ESS rules.
