Can I stack federal and provincial insulation rebates in NB? | Insulation IQ?

Yes -- and doing so is not just allowed, it is actively encouraged. The federal and provincial programs in New Brunswick are designed to work in tandem, and stacking them on the same insulation project is one of the smartest financial decisions you can make when upgrading your home's thermal envelope. Understanding the mechanics of how these programs interact will help you capture every dollar available.

The two main programs are the Canada Greener Homes Grant (federal) and NB Power's Home Energy Efficiency Program (provincial). Both target the same types of upgrades -- attic insulation, wall insulation, basement and crawl space insulation, and related air sealing work -- and both can apply to the same project, on the same home, in the same year. The key rule is that you cannot claim the same dollar of project cost against both programs simultaneously. Each program covers its portion of eligible expenses independently, so you are not double-dipping on the same receipts; you are simply accessing two separate funding sources for a single improvement project.

The Canada Greener Homes Grant provides up to $5,000 in rebates across a combination of eligible retrofit measures, plus up to $600 toward EnerGuide assessment costs (pre- and post-retrofit audits conducted by a registered energy advisor). The EnerGuide assessment is mandatory for the federal grant and it quantifies your home's energy performance before and after the work, which is the basis for calculating your rebate. In Climate Zone 6 -- which covers all of New Brunswick including Fredericton, Moncton, Saint John, Miramichi, and Bathurst -- the baseline R-values expected to qualify for maximum rebates are typically R-50 or better in the attic, R-20 or better in the basement, and appropriate improvements for walls and crawl spaces.

NB Power's Home Energy Efficiency Program operates separately and calculates rebates based on the R-value improvement achieved, the square footage of the area insulated, and the specific measure type. Common rebate amounts run approximately $0.10 to $0.15 per square foot for attic insulation upgrades and up to $500 or more per measure for basement, crawl space, or wall insulation depending on the improvement achieved. NB Power's program does not require a separate audit if you already have an EnerGuide assessment on file, which means the energy assessment you pay for (and partially recover) through the federal grant also unlocks access to the NB Power rebates.

On a typical New Brunswick insulation project -- say, upgrading an attic from R-20 to R-60 and insulating the basement rim joist and walls -- a homeowner might realistically receive $1,500 to $3,500 from NB Power and $2,000 to $5,000 from the Canada Greener Homes Grant, depending on square footage and the scope of work. Combined, this can offset a very meaningful portion of total project costs, which often range from $5,000 to $15,000 for a comprehensive attic-plus-basement retrofit in an average New Brunswick home.

There are a few important timing and procedural points. For the federal grant, you must register your project before beginning the work, and the pre-retrofit EnerGuide assessment must be completed first. The post-retrofit assessment is then done after the insulation is installed to document the improvement. For NB Power, the process is similar -- register, complete the work, submit receipts and documentation. Because both programs have funding cycles and can close when annual allocations are exhausted, it is worth starting the registration process as early as possible.

Some homeowners in New Brunswick are also eligible for Emergency Home Repair or municipal-level programs that may layer on top of the federal and provincial rebates, particularly for lower-income households or seniors. WorkSafeNB and NB Housing have historically offered supplementary programs worth investigating depending on your household income and property situation.
