Quick Answer
The NSW Energy Savings Scheme (ESS) provides financial incentives to NSW households and businesses that upgrade to energy-efficient appliances, insulation, and heating/cooling systems. Eligible upgrades can generate Energy Saving Certificates (ESCs) worth $30–$600 or more per household, paid as upfront point-of-sale discounts. If you live outside NSW — Victoria has the Victorian Energy Upgrades (VEU) program with similar benefits.
What Is the NSW Energy Savings Scheme?
The NSW Energy Savings Scheme (ESS) is a state government initiative that creates a market for Energy Saving Certificates. When an accredited installer upgrades your home or business with energy-efficient products, they generate ESCs which are sold to electricity retailers. The benefit is passed back to you as a discount on the product or installation cost — often making efficient appliances significantly cheaper than standard models.
The scheme is administered by the NSW Department of Climate Change, Energy, the Environment and Water. It targets residential and commercial upgrades including lighting, heating/cooling, hot water systems, pool pumps, and insulation.
What Upgrades Are Eligible Under the ESS?
Home Appliances and Heating/Cooling
| Upgrade Type | Typical ESC Discount | Notes |
|---|---|---|
| Reverse-cycle air conditioner (split system) | $50–$300 off | Must meet minimum star rating; installed by accredited provider |
| Heat pump hot water system | $200–$600 off | One of the highest-value ESS upgrades; replaces electric storage |
| Pool pump (variable speed) | $100–$250 off | Variable-speed pumps use up to 80% less electricity than single-speed |
| LED lighting upgrade | $1–$5 per fitting | Common in commercial retrofits; residential value lower since most homes already have LEDs |
| Insulation (ceiling or wall) | $100–$400 | Depends on R-value and area; must meet minimum specifications |
Hot Water System Upgrades
Heat pump hot water systems are the most valuable ESS upgrade for most NSW households. They use ambient air rather than a direct heating element, cutting hot water energy use by up to 70% compared to a standard electric storage system. Under the ESS, eligible households can receive $200–$600 in ESC discounts applied directly off the installation price.
Solar hot water systems are also eligible, though the ESS typically generates fewer certificates for solar units than heat pumps in NSW due to the way savings are calculated.
How to Access ESS Discounts
Step 1: Find an Accredited Provider
Only accredited ESS providers can generate certificates on your behalf. Search the NSW ESS accredited provider register and confirm the company is listed before signing a contract. Not all energy retailers or installers are accredited — don’t assume.
Step 2: Get a Quote
Ask the provider to itemise the ESS discount separately from the base product and installation cost. This lets you compare quotes fairly. Some providers bundle the discount into a single “after incentive” price.
Step 3: Complete Installation
The accredited provider handles all paperwork — you don’t need to submit anything to the government. Installation must be completed by a licensed tradesperson (licensed electrician for electrical work, licensed plumber for hot water systems).
Step 4: Receive Your Discount
The discount is applied at the time of purchase or invoice — either as a reduced upfront price or a post-installation credit. Keep your paperwork: you’ll need it for warranty claims and any future resale disclosure.
How Does the VEU Program Compare? (For Victorian Homeowners)
If you are in Melbourne or regional Victoria, the equivalent program is the Victorian Energy Upgrades (VEU) program, formerly known as the Victorian Energy Efficiency Target (VEET). The VEU works similarly — accredited providers create Victorian Energy Efficiency Certificates (VEECs) and pass the discount to you at point of sale.
| Feature | NSW ESS | Victoria VEU |
|---|---|---|
| Certificate type | Energy Saving Certificate (ESC) | Victorian Energy Efficiency Certificate (VEEC) |
| Administering body | NSW DCCEEW | Essential Services Commission (ESC) |
| Heat pump hot water discount | $200–$600 | $300–$700 (varies by zone) |
| Split system AC discount | $50–$300 | $50–$250 |
| Insulation | Eligible | Eligible |
| How to access | Accredited provider; point-of-sale discount | Accredited provider; point-of-sale discount |
Top Tips and Gotchas
- Confirm accreditation first. Not every company advertising “ESS discounts” is actually accredited. Check the official register before signing anything.
- Get itemised quotes. Always ask for the base price and the ESC discount separately so you can compare across providers.
- Licensing matters. Even with ESS accreditation, all electrical and plumbing work must be done by a licensed tradesperson. Ask to see their licence number.
- Renters can benefit too. If your landlord replaces a hot water system or AC, the landlord can access the ESC discount — advocate for them to do so.
- Don’t double-dip. Some products are eligible for both ESS and federal government rebates (e.g. Small-scale Renewable Energy Scheme for solar). Your installer should maximise all available incentives.
- Victorian equivalent is VEU. Melbourne homeowners should check veu-registry.vic.gov.au for the VEU accredited provider register.
- Upgrade before rules change. ESS discount rates can change when the government reviews the scheme — upgrades that qualify now may attract different discounts in future years.
- Ask about bundled deals. Some accredited providers offer multiple upgrades in a single visit (e.g. hot water + insulation + lighting), increasing total certificate value and reducing call-out costs.

Frequently Asked Questions
Do I need to apply for the ESS discount myself?
No — the accredited provider handles all certificate creation. The discount is applied at point of sale or on your invoice. You just need to use an accredited company and ensure the product meets the scheme requirements.
Can I get the ESS discount on a second-hand appliance?
No. ESS discounts only apply to new, eligible equipment installed by an accredited provider. Refurbished or second-hand products do not qualify.
I’m in Melbourne — can I access the NSW Energy Savings Scheme?
No, the NSW ESS is only available to NSW addresses. Melbourne homeowners should access the equivalent Victorian Energy Upgrades (VEU) program through an accredited VEU provider. Visit the VEU Registry to find providers.
How much is the average ESS discount on a heat pump hot water system?
In NSW, the typical point-of-sale discount for replacing an electric storage hot water system with a heat pump is $200–$600, depending on the system capacity, the current ESC spot price, and which accredited provider you use. Victorian VEU discounts are often slightly higher, ranging from $300–$700.
Does the ESS cover rental properties?
Yes — landlords can access ESS discounts on upgrades to investment properties. The accredited provider generates the certificates based on the property address, regardless of whether the occupant is an owner or tenant.
Can the ESS discount be combined with federal government incentives?
In many cases, yes. For example, a solar water heater installation may attract both ESS certificates and Small-scale Technology Certificates (STCs) under the federal Small-scale Renewable Energy Scheme. A good accredited provider will maximise all available incentives for your specific upgrade.
