Overview of the Sustainable Household Scheme in the ACT

The Sustainable Household Scheme is an initiative delivered by the ACT Government to assist Canberra homeowners and community organisations with sustainable home energy solutions. Finance for the program is administered through the designated loan provider, Brighte Capital Pty Ltd.

Under scheme guidelines, eligible Scheme participants can access low-interest loans from $2,000 to $20,000 across approved sustainability categories. A maximum loan limit of $20,000 will apply to all products for new applicants. Standard scheme financing carries a low interest rate of 3% applies to all loans, structured with zero establishment fees and no account keeping fees. The loan repayment term can be up to ten years.

For earlier participants, previous scheme participants and households that have submitted an application or have received approval for a loan prior to 1 July 2026, can access a maximum of $15,000 over the life of the scheme.

Property Eligibility and Unimproved Value (UV) Limits

To qualify for battery storage or energy efficiency upgrades under Categories A, B, and D, properties must be located in the Australian Capital Territory and satisfy defined rates evaluation metrics.

The Unimproved Value criteria mandate that the UV of the property must be at or below $750,000 in any year from 2022 for freestanding residences and non-unit titled dual occupancies. For residents living in multi-storey unit titled developments, multi-storey apartments the UV of the property must be at or below $300,000 in any year from 2022.

Vehicle acquisitions under Category C are exempt from property value caps. However, specific vehicle purchase price ceilings apply:

• The total cost of the electric car must be less than $60,000.
• The total cost of the electric motorbike must be under the $40,000 threshold.

Concession Card Support and Zero-Interest Financing

While the general scheme offers low-interest financing at 3%, low-income households and concession holders have access to targeted zero-interest funding paths.

Zero-interest loans and loans for solar are available to eligible concession card holders under the Home Energy Support Program. Participating households can receive up to $10,000 in a zero-interest loan. Furthermore, eligible concession card holders may be eligible for $10,000 in zero-interest loans and $5,000 in rebates to offset upfront upgrade expenses.

Installer and Retailer Certification Standards

Quality assurance rules protect homeowners investing in battery and energy storage systems. All installations must follow strict industry accreditation standards:

• For household battery storage, installers must be a Solar Accreditation Australia (SAA) accredited installer.
• Retailers selling and managing the contract must ensure retailers must be a New Energy Tech Consumer Code (NETCC) approved solar retailer.

Consumers enter into supply and installation contracts directly with accredited suppliers. Repayments commence only after the system is installed and operational.

What You Can Check Yourself, and What You Cannot

Before applying, property owners can check their Unimproved Value on recent ACT rates notices or through the ACT Revenue Office portal. Homeowners can also attend the free mandatory Climate Choices workshop online or in person to verify eligibility.

However, participants cannot self-certify battery installations or bypass accredited provider inspections. Physical electrical connections and compliance documentation must be handled exclusively by licensed electricians holding SAA certification and submitted through Access Canberra inspection pathways.

What the Published Sources Do Not Tell You

The official scheme guidelines do not publish individual supplier pricing matrices or guarantee specific annual electricity bill savings, as local financial returns depend heavily on individual household load profiles and retailer feed-in tariffs. In addition, commercial solar systems for private businesses are excluded from the residential guidelines and require separate business energy advisory channels.
