What to confirm before scheduling insulation work
What insulation rebates are available in Utah?
Utah homeowners can access insulation rebates through Rocky Mountain Power Wattsmart (Rocky Mountain Power (Wattsmart), Enbridge Gas Utah (ThermWise)). Insulation rebates are available — check current program. 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 Utah rebate?
Most Utah insulation rebate programs through Rocky Mountain Power Wattsmart 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 Rocky Mountain Power Wattsmart will confirm exactly what improvements qualify in your home.
Does Utah require insulation before a heat pump rebate?
Many Utah heat pump rebate programs through Rocky Mountain Power Wattsmart 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 Rocky Mountain Power (Wattsmart), Enbridge Gas Utah (ThermWise) for current requirements specific to your upgrade path.
Can I combine the Utah 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 Rocky Mountain Power Wattsmart utility rebates. Stack both: apply for the Rocky Mountain Power Wattsmart 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).
