What are the NB Power rebates for replacing windows and doors in New Brunswick?

NB Power's Total Home Energy Savings program offers rebates for window and door upgrades as part of a whole-home energy retrofit, but the program structure, eligibility requirements, and rebate amounts change periodically — always confirm current program details directly with NB Power at nbpower.com before planning your project budget around specific rebate amounts.

As of the 2025-2026 program year, NB Power's energy efficiency programs operate under a framework that typically requires windows and doors to meet specific Energy Star certification levels to qualify for rebates. The program is designed around the concept of a home energy assessment — a registered energy advisor assesses your home before and after the upgrades, and the rebate is calculated based on modelled energy savings rather than a flat per-window amount. This means homes with the oldest, leakiest windows tend to qualify for the largest rebates, since the improvement in modelled energy performance is greatest.

The practical process for accessing window rebates through NB Power typically works like this: you book a pre-retrofit home energy assessment with a registered energy advisor (NRCan certified), receive a report identifying upgrades and estimated savings, proceed with the qualifying window replacement using Energy Star certified products, have a post-retrofit assessment completed, and then submit the rebate application with invoices and both assessment reports. The energy advisor's fees themselves are often partially subsidized as part of the program. This multi-step process takes time — plan for 4-8 weeks from initial assessment to rebate receipt.

Beyond NB Power's programs, it's worth noting that the Canada Greener Homes Grant program, which offered federal rebates for window upgrades, has undergone significant changes at the federal level. The current federal program structure as of early 2026 should be confirmed at canada.ca/greener-homes before factoring it into your budget. Some NB homeowners have successfully layered provincial and federal incentives for a larger combined rebate.

What to watch for when pursuing rebates: the window brand and Energy Star certification level matter — not just any Energy Star window qualifies for maximum rebates, and the program specifies minimum performance criteria (U-factor, ER rating) that your window must meet. Keep all product specification sheets and invoices. Some contractors who frequently work with the rebate program can help guide you through the documentation requirements, but verify their familiarity is current, since program details change year to year.

One important note: never design your renovation budget assuming a specific rebate amount will be approved. Treat any rebate as a welcome bonus rather than a committed piece of your financing plan. If the rebate comes through, great — it offsets part of the cost. If the program requirements changed since you last checked, or your chosen windows don't meet the current specification threshold, you don't want to be caught short. Get the pre-assessment done early and confirm rebate eligibility in writing before signing a contract.

For the most current program details, call NB Power's energy efficiency line directly or visit nbpower.com and navigate to the energy savings section. A registered energy advisor in your area can also walk you through what's currently available and help you prioritize which upgrades give you the best combination of energy savings and rebate value.
