Is there a federal rebate for insulation in 2026?

Yes, two federal rebate programs cover insulation in 2026. The HEAR program provides up to $1,600 (low income) for standalone insulation, air sealing, and ventilation work with no energy modeling required. The HOMES program provides up to $8,000 for insulation as part of a whole-home retrofit that achieves at least 15% whole-home energy savings. Both require household income below 150% of Area Median Income.

Did the 25C tax credit for insulation expire?

Yes. The Section 25C energy efficiency tax credit, which covered insulation at 30% up to $1,200 per year, was terminated by the One Big Beautiful Bill effective December 31, 2025. Insulation installed in 2026 is not eligible for the 25C credit. The HOMES and HEAR direct rebate programs remain available as the primary federal incentives.

Which is better for insulation — HOMES or HEAR?

HOMES is typically better if you are planning a comprehensive retrofit (insulation + air sealing + heat pump, for example) because the maximum rebate is $4,000-$8,000 versus HEAR's $800-$1,600 for insulation. HEAR is better if you only want to add insulation without committing to a whole-home project, or if your state's HOMES program is not yet active. You can use HEAR for insulation now and HOMES for other improvements later.

What types of insulation qualify for federal rebates?

HOMES and HEAR rebates are performance-based — they care about the energy savings achieved, not the specific insulation material. Qualifying insulation types include blown-in fiberglass, blown-in cellulose, spray foam (open and closed cell), rigid foam board, fiberglass batts, mineral wool batts, and dense-pack cellulose for wall cavities. The insulation must be installed by a licensed contractor and meet applicable building codes.

How much can I save on energy bills with attic insulation?

Upgrading attic insulation from R-11 to R-49 in a 1,500 square foot attic typically saves $300-$700 per year on heating and cooling costs, depending on your climate, current HVAC system, and local energy prices. In colder climates like the Northeast and Midwest, savings are on the higher end. The savings are ongoing for the 30-50 year life of the insulation.

Can I combine insulation rebates with utility rebates?

Yes. Federal HOMES and HEAR rebates stack directly with utility company insulation rebates and state-funded programs. In Massachusetts, for example, a low-income household could receive $8,000 from HOMES plus $2,000-$4,000 from Mass Save on the same insulation and air sealing project. Utility rebates are processed separately and typically paid 4-8 weeks after installation.

Do I need an energy audit to get an insulation rebate?

For HOMES, yes — a BPI-certified energy audit is required to model the energy savings and establish your baseline for the rebate. For HEAR insulation rebates, an energy audit may not be required depending on your state, though a site assessment is typically done. Utility rebates vary — some require a pre-inspection, others accept contractor invoices and photos. An audit is always a worthwhile investment regardless of rebate requirements, as it identifies the highest-value improvements for your specific home.

Insulation Rebates 2026: Federal & Utility Programs for Homeowners

Last updated: February 20, 2026

Insulation sits at a peculiar position in the energy rebate world: it is the improvement most likely to qualify for the HOMES program, yet it does not stand alone as a HEAR-eligible item the way a heat pump or water heater does. Understanding the distinction is what separates homeowners who successfully claim rebates from those who apply for the wrong program and get rejected.

The short version: if you are only adding insulation and air sealing, HEAR can cover up to $1,600. If you are doing insulation as part of a broader whole-home retrofit that cuts your energy use by 15%+, HOMES is far more valuable — up to $8,000. Most homeowners doing serious insulation work should be thinking HOMES, not HEAR. Use our rebate calculator to see which program fits your planned project.

Federal Insulation Rebates in 2026

The 25C tax credit that previously covered insulation (30% credit, up to $1,200 per year) was terminated by the One Big Beautiful Bill effective December 31, 2025. For insulation installed in 2026 or later, there is no federal tax credit. The available federal rebate programs are:

Program	Insulation Coverage	Max Rebate	Requirement
HOMES	Part of whole-home retrofit	$4,000–$8,000	15%+ whole-home energy savings, income-based
HEAR	Insulation + air sealing standalone	$800–$1,600	Income below 150% AMI

Both programs survived the OBBB changes. Both are direct rebates — money off your project cost, not a tax credit claimed a year later. The critical difference is the scope of work required to access each program.

HOMES Program: Whole-Home Insulation Approach

The HOMES program was specifically designed around whole-home performance, and insulation is typically the centerpiece of any HOMES-funded retrofit. This is because insulation — combined with air sealing — is the single most reliable way to cut a home’s heating and cooling energy use by the 15% minimum that HOMES requires.

The HOMES rebate structure:

Income Tier	AMI Threshold	Max Rebate	Cost Coverage
Low income	≤80% AMI	$8,000	Up to 80% of project cost
Moderate income	80–150% AMI	$4,000	Up to 50% of project cost
Market rate	>150% AMI	Limited/state-dependent	Typically requires 35%+ savings

What “whole-home” means in practice: a BPI-certified contractor runs an energy audit that models your home’s current energy use. They identify the largest efficiency gaps — typically air leakage, inadequate attic insulation, and sometimes wall insulation — and design a package of improvements to hit the 15% savings threshold. Insulation is almost always the anchor improvement because it delivers the largest energy reduction per dollar spent.

A typical HOMES-qualifying project for a 1970s home might include: blown-in attic insulation (R-38 to R-60), air sealing throughout the house (especially attic penetrations, rim joists, and basement ceiling), and sometimes a heat pump replacement — all together achieving 25–35% energy reduction.

The HOMES rebate applies to the entire project cost, not just the insulation portion. This is why a $12,000 project with $6,000 in insulation and $6,000 in air sealing and HVAC work gets the full HOMES rebate up to $8,000 for low-income households — the rebate is based on the whole project’s qualifying cost and energy savings.

Read the full details in our HOMES program guide, including step-by-step application instructions.

HEAR: Insulation and Air Sealing Rebate

The HEAR program includes insulation and air sealing as a rebate category, but with a cap much lower than HOMES — and without the whole-home performance requirement. This makes HEAR useful for households who want to add insulation independently, without committing to a full retrofit.

HEAR insulation/air sealing/ventilation rebate:

≤80% AMI: Up to $1,600, covering up to 100% of project cost
80–150% AMI: Up to $800, covering up to 50% of project cost
>150% AMI: Not eligible

The $1,600 cap is fairly modest — a whole-house air sealing and attic insulation project typically runs $2,500–$8,000 depending on home size and existing insulation level. For low-income households, $1,600 covers a standalone attic insulation job on a small to medium home. For larger homes or more comprehensive insulation work, HOMES is the better program.

One situation where HEAR insulation is the right choice: you are a HEAR-eligible household in a state where HOMES is not yet launched. You can get immediate HEAR rebates for insulation now, and come back for a HOMES rebate later when the program launches in your state — as long as HOMES covers different project components.

Also worth noting: HEAR covers insulation alongside other HEAR-eligible appliances in the same project. If you are replacing a heat pump, water heater, and adding attic insulation all at once, HEAR can rebate all three items up to the per-household maximum ($14,000 for low-income, $7,000 for moderate-income). See the HEAR program guide for per-household caps and stacking rules.

Types of Insulation That Qualify

For HOMES and HEAR rebates, the program cares about the energy performance outcome, not the specific insulation product. That said, here is how common insulation types compare and where they are typically used:

Blown-In Fiberglass or Cellulose (Attic)

The most cost-effective insulation upgrade for most homes. Blown-in material fills in gaps and settles into existing insulation, reaching R-38 to R-60 target levels. Cost: $1,500–$4,000 for a typical attic. This is the most common component in HOMES projects because it delivers the highest energy savings per dollar. Both fiberglass and cellulose qualify for rebates; cellulose (made from recycled paper) has a higher R-value per inch.

Spray Foam (Air Sealing + Insulation)

Two-component spray polyurethane foam (closed-cell or open-cell) provides both insulation and an air barrier. Especially effective at rim joists (the perimeter of the foundation), attic penetrations, and irregularly shaped cavities. Closed-cell spray foam has R-value around 6–7 per inch; open-cell around R-3.5–4. More expensive than blown-in but provides better air sealing.

Rigid Foam Board (Basement and Exterior Walls)

Polyisocyanurate, XPS, or EPS boards installed on basement walls, exterior wall sheathing, or under roofing. R-values range from R-4 (EPS) to R-8 (polyiso) per inch. Used in wall retrofits and for creating a continuous thermal barrier. Higher installation complexity and cost than blown-in attic insulation.

Batt Insulation (Wall Cavities)

Fiberglass or mineral wool batts installed in open wall cavities during renovation. R-13 to R-21 per 3.5-inch stud bay. Common in gut renovations where walls are already open. Less common in standalone insulation projects because accessing wall cavities without opening walls requires specialized dense-pack techniques.

Dense-Pack Wall Insulation

Cellulose blown into closed wall cavities through small holes drilled from inside or outside. Effective for existing walls without opening them up. Cost: $1,200–$4,000 per floor of exterior walls. Less common than attic insulation but very high value for homes with uninsulated 2x4 exterior walls (typical of pre-1970 construction).

Utility Insulation Rebates by State

Beyond federal programs, many utilities offer insulation rebates as part of their energy efficiency portfolios. These are fully stackable with HOMES and HEAR:

Utility / State	Program	Insulation Rebate
Mass Save (MA)	No-Interest HEAT Loan + Rebates	$2,000–$4,000 for qualified air sealing + insulation
National Grid (NY)	Home Performance with ENERGY STAR	$500–$3,000 depending on scope
Efficiency Maine (ME)	Home Energy Savings Program	$1,500–$3,000
Eversource (MA/CT/NH)	Home Energy Solutions	$500–$2,000
Xcel Energy (CO/MN)	Home Energy Improvement Program	$200–$800
Pacific Gas & Electric (CA)	Energy Upgrade California	Varies; project-based
Focus on Energy (WI)	Home Performance	$200–$600

The strongest programs — Massachusetts, Maine, Vermont, and New York — often pair rebates with 0% financing options that make the upfront cost nearly irrelevant. A $6,000 insulation project financed at 0% over 7 years with $2,000 in immediate rebates costs $57/month while saving $100–$200/month in energy.

ROI Analysis: Insulation Cost vs. Energy Savings

Insulation consistently delivers among the highest ROI of any home improvement — energy or otherwise. Here is a realistic breakdown for the most common scenarios:

Attic Air Sealing + Blown-In Insulation (1,500 sq ft attic, from R-11 to R-49)

Installed cost: $3,500–$5,500
Annual energy savings: $400–$800 (depending on climate and current HVAC)
HEAR rebate (low-income, standalone): −$1,600
Utility rebate (Massachusetts example): −$2,000
Net cost after rebates: $0–$1,900
Simple payback (with rebates): 0–5 years
Lifetime savings (20 years): $8,000–$16,000

Whole-Home Retrofit (Attic + Wall + Air Sealing + Heat Pump)

Installed cost: $15,000–$25,000
Annual energy savings: $1,200–$2,400
HOMES rebate (low-income, 25% savings): −$8,000
HEAR heat pump rebate: −$8,000
Utility rebates (various): −$1,000–$3,000
Net cost after rebates: $0–$6,000
Simple payback: 0–5 years

These numbers explain why the HOMES program specifically targets whole-home projects: the combination of insulation, air sealing, and HVAC work creates synergistic savings that exceed any individual measure. For more on combining improvements, see our guide to stacking energy rebates.

Finding a Qualified Insulation Contractor

For HOMES projects, you need a BPI-certified contractor. For HEAR insulation, most state programs also require licensed contractors, though the certification requirement may be less stringent than for HOMES.

Where to Find Qualified Contractors

BPI Contractor Finder: bpi.org/find-a-contractor — search by zip code for BPI Building Analyst certified contractors
ENERGY STAR Home Performance: energystar.gov/campaign/improvements/findcontractor
State HOMES program websites: Most states with active programs maintain approved contractor lists
Your utility’s contractor network: Many utilities maintain pre-vetted lists for rebate program participants

What a Good Contractor Does

A quality insulation contractor for rebate projects will: conduct a blower door test to measure current air leakage, perform a visual inspection of existing insulation levels and HVAC systems, run energy modeling software to predict the savings from proposed improvements, and handle rebate paperwork on your behalf. Do not hire any contractor who skips the energy audit and jumps straight to selling insulation products.

Getting Multiple Quotes

Get at least three quotes for any project over $3,000. Prices for attic insulation vary significantly even among BPI-certified contractors. The quote should itemize: energy audit cost (often reimbursable), materials (R-value, type, square footage), labor, and an explicit statement of expected energy savings percentage (required for HOMES applications).

Be wary of contractors who “guarantee” a specific rebate amount before completing the audit. Rebates are determined by actual energy modeling results — no contractor can commit to a specific dollar amount before the audit is done.

How to Apply for Insulation Rebates

The path depends on whether you are pursuing HOMES, HEAR, or a utility rebate (or all three):

HOMES Application Path

Verify your state’s HOMES program is accepting applications (see state rebates — currently 23 states open)
Hire a BPI-certified contractor through your state’s approved list
Complete energy audit and review proposed scope of work
Contractor submits application with energy model showing 15%+ savings
Wait for pre-approval (2–6 weeks)
Complete work, pass inspection
Receive rebate (point-of-sale or reimbursement depending on state)

HEAR Insulation Application Path

Confirm your income tier (see income eligibility guide)
Find a HEAR-enrolled contractor in your state
Bring income documentation to appointment
Contractor applies rebate at point of sale

Utility Rebate Application Path

Check your utility’s rebate program requirements before starting work
Use a utility-approved contractor if required
Submit rebate application with contractor invoice and proof of installation
Receive rebate check by mail or direct deposit (typically 4–8 weeks)

The key is doing all three applications in parallel. Some homeowners chase rebates sequentially and miss deadlines. A good contractor handles all three applications simultaneously — ask about this explicitly when getting quotes.
