Rates based on $600,000 owner-occupier P&I loan, 80% LVR. NatHERS 7+ star eligibility. Rates are indicative and subject to change. "Lowest" = the lowest rate on our live CDR feed at the time of viewing, across the lenders we display, excluding products with restricted eligibility (e.g. defence service). "Curated" = a rate we maintain manually from the lender's published pricing (used where the lender does not publish it via CDR) and verify against the lender's website. Rates update daily and not all lenders are included, so other products may be lower. Source: Consumer Data Right (CDR), lender websites, CEFC. Last updated: 5 September 2026. Warning: This comparison rate is true only for the examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate.

NSW Green Incentive Stacking
Combine green loan discounts with NSW and federal incentives for maximum savings.
Energy Savings Scheme (ESS)
The NSW ESS creates financial incentives for energy-efficient upgrades. Accredited providers issue Energy Savings Certificates (ESCs) for qualifying installations including insulation, efficient lighting, heat pumps, and building shell improvements.
| Type | State government scheme |
| Benefit | ESC certificates for upgrades |
| Eligible upgrades | Insulation, heat pumps, lighting |
| Typical value | $500-$2,000 |
PDRS & Virtual Power Plants
The Peak Demand Reduction Scheme (PDRS) rewards battery owners who participate in Virtual Power Plant programs. By allowing your battery to export stored solar energy during peak demand, you can earn payments of up to $1,500 per year.
| Type | State demand reduction scheme |
| VPP payments | Up to $1,500/year |
| Requirement | Battery + VPP enrolment |
| Programs | Tesla, AGL, Origin, Amber |
Federal STCs (Solar Rebate)
Small-scale Technology Certificates provide an upfront discount on solar panel installations across Australia, including NSW. The rebate reduces the cost of a 6.6kW system by $2,500-$3,500. STCs are available until 2030 but decrease each year.
| Type | Federal government rebate |
| Value (6.6kW) | $2,500-$3,500 |
| Available until | 2030 (reducing) |
| Applied | Upfront at purchase |
Incentive Stacking Strategy for NSW
Sydney example: $1.15M home with a green home loan at 0.40% discount, 6.6kW solar with STCs, battery with PDRS/VPP, and ESS certificates for insulation. Total combined annual benefit significantly exceeds a standard loan.
| Green rate saving (annual) | ~$4,600 |
| Solar bill savings (annual) | $1,200-$2,000 |
| VPP/PDRS payments (annual) | Up to $1,500 |
| Upfront STCs + ESS | $3,000-$5,500 |
NSW stacking strategy: Combining the green loan rate discount with NSW battery rebates, federal STCs ($2,500-$3,500 off a 6.6kW system), and lower energy bills can deliver $8,000+ upfront and $3,000-$5,000 in annual savings - higher in metro Sydney where energy prices are above the national average.
