What to confirm before scheduling insulation work
What insulation rebates are available in Vermont?
Vermont homeowners can access insulation rebates through Efficiency Vermont (Green Mountain Power (GMP), Vermont Electric Cooperative (VEC), Vermont Gas Systems (VGS)). Insulation rebates are up to $9,500. Air sealing rebates are available — check current program. Rebates typically cover attic insulation to R-49 or higher, basement wall insulation, and sometimes floor/crawlspace insulation. A home energy assessment is usually required first. Exact amounts depend on your utility and current program rules.
How much insulation do I need to qualify for the Vermont rebate?
Most Vermont insulation rebate programs through Efficiency Vermont require adding insulation to bring your home up to current code standards (typically R-38 to R-60 in the attic depending on climate zone). If your existing insulation is already at R-38 or higher, you may not qualify for the attic insulation rebate. A home energy assessment through Efficiency Vermont will confirm exactly what improvements qualify in your home.
Does Vermont require insulation before a heat pump rebate?
Many Vermont heat pump rebate programs through Efficiency Vermont recommend or require weatherization (including insulation and air sealing) before approving a whole-home heat pump rebate. This is not a penalty — a well-insulated home needs a smaller heat pump system, has lower operating costs, and qualifies for the full rebate tier. Check with Green Mountain Power (GMP), Vermont Electric Cooperative (VEC), Vermont Gas Systems (VGS) for current requirements specific to your upgrade path.
Can I combine the Vermont insulation rebate with the federal tax credit?
Yes. The federal 25C Energy Efficient Home Improvement Credit covers 30% of insulation and air sealing costs up to $1,200 per year — completely separate from Efficiency Vermont utility rebates. Stack both: apply for the Efficiency Vermont rebate after installation, and claim the 25C credit on your tax return for the same year. Note: the 25C credit for insulation requires the insulation to primarily reduce heat loss/gain (decorative materials don't qualify).
