Rates based on $520,000 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.

Green savings example: On a $520,000 Tasmanian loan over 30 years, a 0.40% green discount - saving roughly $130/month, or around $47,000 over the life of the loan, on top of bill savings from running an efficient home.

Eligible Green Upgrades in Tasmania
Energy upgrades that qualify for green loan eligibility and maximise cold-climate savings.
Insulation & Glazing
Tasmania's cold climate makes insulation the highest-impact green upgrade. Heavy ceiling, wall, and underfloor insulation dramatically reduces heating costs. Double glazing is critical - many older Tasmanian homes have single-glazed windows that account for 40% of heat loss. The most cost-effective upgrade for Tasmanian homes.
- Full insulation (TAS)
- $3,000-$6,000
- Double glazing
- $8,000-$20,000
- Heating bill savings
- $800-$1,500/yr
Solar PV Panels
Hobart receives approximately 3.5 peak sun hours per day - lower than mainland capitals but still viable for solar. A 6.6kW system costs $4,500-$7,000 after STCs and generates 18-23kWh/day. Tasmania's long summer daylight hours compensate for lower winter output. Payback period: 4-6 years.
- 6.6kW system (TAS)
- $4,500-$7,000
- Annual savings
- $1,000-$1,600
- Payback
- 4-6 years
Battery Storage
Battery storage in Tasmania provides backup power during outages and stores solar energy for evening use. Particularly valuable in rural and remote areas of Tasmania. The federal battery rebate helps offset costs. Batteries qualify for green loan eligibility with most lenders.
- 10kWh battery (TAS)
- $8,000-$12,000
- Federal rebate
- Available
- Payback
- 7-10 years
Heat Pump Hot Water & Heating
Heat pump systems are critical in Tasmania's cold climate. Heat pump hot water uses 65% less energy than electric storage. Reverse-cycle heat pumps provide efficient heating, outperforming electric heaters 3:1 on energy efficiency. Federal STCs provide an upfront discount, and Tasmania's hydro electricity means heat pumps run on 100% renewable power.
- Heat pump HW (installed)
- $3,000-$5,000
- Annual savings
- $400-$800
- Federal STCs
- Available
EV Chargers
Level 2 home EV charger installation in Tasmania costs $1,500-$5,000. Tasmania's 100% hydro electricity makes EV charging truly zero-emission - a unique advantage over mainland states. Smart chargers paired with solar panels enable free daytime charging. Accepted by select lenders for green eligibility.
- Level 2 charger (TAS)
- $1,500-$5,000
- Annual fuel savings
- $1,000-$2,000
- Grid emissions
- Zero (hydro powered)
Draught Sealing & Airtightness
Draught sealing is one of the most cost-effective upgrades for older Tasmanian homes. Cold draughts around doors, windows, and floorboards can account for 15-25% of heat loss. Professional draught sealing costs relatively little and delivers immediate comfort and savings in Tasmania's cold winters.
- Professional sealing
- $500-$1,500
- Heating bill reduction
- 15-25%
- Payback
- Under 1 year
Tasmania Green Incentive Stacking
Combine green loan discounts with federal incentives and Tasmania's renewable hydro advantage.
Federal STCs (Solar Rebate)
Small-scale Technology Certificates provide an upfront discount on solar panel installations in Tasmania. The rebate reduces the cost of a 6.6kW system by $2,500-$3,500. While Tasmania has lower solar irradiance than mainland states, solar is still viable and generates solid returns. 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 offset the cost of home battery storage for Tasmanian households. Battery storage is particularly valuable in Tasmania for storing solar energy during short winter days and providing backup during power outages, which can occur in remote Tasmanian areas during severe weather.
| Type | Federal government rebate |
| Stacks with green loan | Yes |
| Backup power benefit | High (remote areas) |
| Qualifies for green loan | Yes (most lenders) |
Aurora Energy Saver Programs
Aurora Energy, Tasmania's government-owned electricity retailer, offers energy efficiency programs and payment assistance for Tasmanian households. These programs can complement green home loan savings by providing additional support for energy-efficient upgrades, particularly insulation and heating improvements for Tasmania's cold winters.
| Type | State energy retailer programs |
| Provider | Aurora Energy |
| Focus | Insulation & heating |
| Eligibility | TAS households |
Incentive Stacking Strategy for Tasmania
Hobart example: $650K home with a green home loan at 0.40% discount, insulation upgrades, 6.6kW solar with STCs, and federal battery rebate. Tasmania's 100% hydro grid means solar exports offset already-clean electricity, while insulation delivers the highest returns due to cold winters.
| Green rate saving (annual) | ~$2,080 |
| Heating savings (insulation) | $800-$1,500 |
| Solar bill savings (annual) | $1,000-$1,600 |
| Upfront federal STCs | $2,500-$3,500 |
Tasmanian stacking strategy: A green loan discount + Energy Saver Loan Scheme + federal STCs ($2,500-$3,500 off a 6.6kW system) + lower bills can deliver $8,000+ upfront. Tasmania's heating-heavy load means efficiency upgrades pay back faster than in warmer states.
NatHERS Requirements for Green Loans in Tasmania
All major green loan lenders require a minimum NatHERS rating of 7 stars. Tasmania adopted the NCC 2022 energy provisions in October 2023, meaning new homes built since then should meet this standard automatically. For older homes, insulation upgrades and solar panels are the most accessible pathways - particularly valuable given Tasmania's cold climate and high heating demands.
| 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 |

Building Green in Tasmania
Tasmania adopted the NCC 2022 energy efficiency provisions in October 2023, requiring all new residential builds to achieve a minimum 7-star NatHERS rating. New homes built in Tasmania since late 2023 automatically qualify for green home loan discounts. Tasmania's cold, wet climate demands a design approach focused on heavy insulation, airtightness, thermal mass, and maximising north-facing solar gain - heating energy is the dominant consideration in Tasmanian home design.
NCC 2022 in Tasmania
- 7-star minimum for new builds
- Whole-of-home energy budget
- Adopted October 2023
- Cold climate insulation emphasis
TAS NatHERS climate zones
- Hobart - cool temperate (zone 26)
- Launceston - cold climate
- West coast - cold and wet
- Highland areas - alpine/sub-alpine

- Heavy insulation (ceiling, walls, floor)
- North-facing windows for winter solar gain
- Airtight construction with controlled ventilation
- Thermal mass for heat retention overnight
