The Home Energy Fund, explained
The Home Energy Fund would let homeowners borrow for solar, batteries, insulation and heat pumps at a low interest rate, with the loan secured against the property and repaid through council rates over roughly ten years. National would also remove the council consent requirement for installing solar.
It is a financing mechanism, not a subsidy. There is no cash grant. You still pay the full cost of the system, just spread over a long term at a low rate and attached to the property rather than to you personally.
The mechanics
Secured against your property
The loan attaches to the house rather than to you as an individual. That is what allows the long term and the low rate, and it is the same model Local Government New Zealand has advocated through its Ratepayer Assistance Scheme.
Repaid through your rates
Repayments are collected with your council rates over about ten years, rather than as a separate loan repayment to a bank.
Covers more than solar
Rooftop solar, home batteries, insulation and heat pumps would all be eligible, so it functions as a general home energy upgrade fund rather than a solar-specific scheme.
No council consent for solar
National would remove the council consent requirement for solar installations, cutting time and cost out of the process. Most residential installs already do not require building consent, so the practical effect varies by council.
Who would run it, and who pays
The fund would be jointly owned by central and local government. The Crown would put in a $7 million equity investment for a 20 percent shareholding in a new entity, with participating councils funding the balance.
National has described its policy as a narrower version of the Ratepayer Assistance Scheme long proposed by Local Government New Zealand. That narrower scope is the main structural difference from Labour's competing package, which uses the same underlying model at a larger scale.
The conditions worth knowing
- Roughly 20% home equity is required. This is the condition most likely to exclude people. Recent buyers and those with high loan-to-value ratios may not qualify.
- Councils opt in voluntarily. If your council chooses not to participate, the scheme is not available to you regardless of your equity position. Coverage could end up patchy across the country.
- It is a loan, not a grant. You repay the full cost. The benefit is the rate and the term, not free money.
- Renters are not covered. The policy is aimed at property owners.

How it compares to what you can get today
