"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.

Green savings example: On a $600,000 QLD loan over 30 years, a 0.40% green discount - saving roughly $150/month, or around $54,000 over the life of the loan, on top of bill savings from running an efficient home.

Eligible Green Upgrades in Queensland
Energy upgrades that qualify for green loan eligibility and federal incentives.
Solar PV Panels
Queensland has the highest solar irradiance of any Australian capital. Brisbane averages 5.2 peak sun hours per day. A 6.6kW system costs $4,500-$7,000 after STCs and generates 28-33kWh/day. Payback period in Queensland: 2.5-4 years - the fastest in Australia.
- 6.6kW system (QLD)
- $4,500-$7,000
- Annual savings
- $1,500-$2,500
- Payback
- 2.5-4 years
Battery Storage
The federal battery rebate helps reduce costs for Queensland households. The QLD Battery Booster has ended, but high solar generation makes batteries particularly effective in Queensland for self-consumption and VPP income. Qualifies for green loan eligibility.
- 10kWh battery (QLD)
- $10,000-$14,000
- VPP earnings/year
- $300-$1,000
- Payback
- 7-10 years
EV Chargers
Level 2 home EV charger installation in Queensland costs $1,500-$5,000. The QLD EV subsidy ended in September 2024. Smart chargers integrate with solar for free daytime charging - particularly effective in Queensland's high-solar climate. Accepted by select lenders for green eligibility.
- Level 2 charger (QLD)
- $1,500-$5,000
- Annual fuel savings
- $1,000-$2,000
- QLD EV subsidy
- Ended Sept 2024
Insulation & Glazing
In Queensland's hot climate, ceiling insulation is critical for reducing cooling costs. Reflective roof insulation and double glazing can reduce heat transfer by 30-50%. Particularly impactful for west-facing windows in Brisbane's subtropical climate.
- Ceiling insulation
- $1,500-$3,500
- Double glazing
- $8,000-$20,000
- Payback (insulation)
- 2-4 years
Heat Pump Hot Water
Heat pump hot water systems use 65% less energy than electric storage. Queensland's warm ambient temperatures make heat pumps exceptionally efficient year-round. Federal STCs provide an upfront discount. Ideal replacement for older electric or gas storage systems.
- Heat pump (installed)
- $3,000-$5,000
- Annual savings
- $400-$700
- Federal STCs
- Available
Water Efficiency
Rainwater tanks and water-efficient fixtures are particularly valuable in Queensland's variable rainfall climate. SEQ water restrictions have historically driven rainwater tank adoption. While not directly green loan eligible, they complement NatHERS improvements.
- Rainwater tank (5,000L)
- $2,000-$4,000
- Water bill savings
- $200-$500/yr
Queensland Green Incentive Stacking
Combine green loan discounts with federal incentives for maximum savings in the Sunshine State.
Federal STCs (Solar Rebate)
Small-scale Technology Certificates provide an upfront discount on solar panel installations across Australia, including Queensland. The rebate reduces the cost of a 6.6kW system by $2,500-$3,500. Queensland's high irradiance means more STCs are generated per kW, maximising the rebate value. 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 |
Federal Battery Rebate
The federal battery rebate helps Queensland households reduce the cost of home battery storage. The QLD Battery Booster program has ended, but the federal incentive remains. Combined with Queensland's high solar generation, batteries enable significant self-consumption and potential VPP income.
| Type | Federal government rebate |
| Battery rebate | Available to QLD households |
| VPP income potential | $300-$1,000/year |
| QLD Battery Booster | Ended |
Queensland Solar Advantage
Queensland has the highest solar irradiance of any Australian state capital. Brisbane averages 5.2 peak sun hours per day - 37% more than Melbourne. This means solar panels in Queensland generate significantly more electricity, delivering faster payback periods and higher annual savings.
| Brisbane peak sun hours | 5.2 hours/day |
| Solar bill savings (annual) | $1,500-$2,500 |
| Payback period | 2.5-4 years |
| Household solar uptake | 40%+ (highest in AU) |
Incentive Stacking Strategy for Queensland
Brisbane example: $825K home with a green home loan at 0.40% discount, 6.6kW solar with STCs, battery with federal rebate and VPP income. Queensland's exceptional solar generation maximises the energy savings component of total benefits.
| Green rate saving (annual) | ~$2,640 |
| Solar bill savings (annual) | $1,500-$2,500 |
| VPP income (annual) | $300-$1,000 |
| Upfront STCs + battery rebate | $2,500-$5,000 |
Queensland stacking strategy: QLD's high solar yields mean a green loan discount + Battery Booster rebate + federal STCs ($2,500-$3,500 off a 6.6kW system) + bill savings can deliver $10,000+ upfront and $3,500-$5,500 in annual savings.
NatHERS Requirements for Green Loans in Queensland
All major green loan lenders require a minimum NatHERS rating of 7 stars. Queensland adopted the NCC 2022 energy provisions in October 2023, meaning new homes built since then should meet this standard automatically. For older homes, solar panels are the most common eligibility pathway - over 40% of Queensland households already have solar installed.
| Lender | Minimum NatHERS Rating | Alternative Eligibility | Verification Method |
|---|---|---|---|
| CBA | 7 stars | Solar panels (min 3kW) | NatHERS certificate or solar proof |
| Bank Australia | 7 stars | Solar + battery, EPC rating | NatHERS certificate or assessor report |
| Bendigo Bank | 7 stars | Solar panels installed | NatHERS certificate |
| Westpac | 7 stars | Solar, battery, EV charger | NatHERS certificate or installer receipt |
