Insulation Rebates: Where to Find Them and How to Qualify
Rebates can cut the cost of attic insulation and air sealing. Most come from your utility, and the rules matter.
Where insulation rebates come from
- Your electric or gas utility: the most common source. Many offer rebates for attic insulation and air sealing, sometimes requiring a home energy audit or a participating contractor.
- State energy programs, including federally funded home energy rebate programs that states run on their own schedules. Availability and income rules vary by state.
- Local and weatherization programs for income-qualified households.
The DSIRE database lists incentives by state, and your utility's website lists its current rebates. Several of our city cost guides cover local utility rebates.
Federal tax credit
The federal Energy Efficient Home Improvement Credit (Section 25C) covered insulation and air sealing, but 2025 federal legislation ended it for improvements placed in service after December 31, 2025. Check IRS.gov for the current rules before counting on it.
How to get the rebate
- Check the program rules before work starts. Many require pre-approval or a participating contractor.
- Ask whether an energy audit or before/after inspection is required.
- Keep the invoice showing the R-value or depth installed and the area covered.
- Submit on time. Many rebates have deadlines after installation.
