In 2025, energy efficiency remains a top priority for New Zealand homeowners. With rising power bills and changing climate patterns, making homes warmer and more energy-efficient has become critical. That’s where the double glazing grant NZ eligibility scheme under the Energy Efficiency NZ Grant 2025 initiative comes in. This program offers funding to assist households in upgrading their windows with double-glazed units, reducing heat loss and enhancing indoor comfort.
If you’re looking to make your home more sustainable or upgrade old single-pane windows, this article covers everything you need to know—from who qualifies to how much funding is available and how to apply.
What Is the Double Glazing Grant?
The double glazing grant NZ eligibility initiative is part of the government’s broader Energy Efficiency NZ Grant 2025 plan. Administered by the Energy Efficiency and Conservation Authority (EECA), the grant helps New Zealanders reduce energy consumption and heating costs by subsidizing window insulation.
Eligible homeowners can receive up to 30% of installation costs covered, capped at a maximum of NZD $4,000 per household. The grant is available for both retrofit double glazing and new installations in principal residences.
This move is especially timely as winter utility bills surge across the country and older homes struggle to maintain efficient thermal performance.
