The Weatherization Assistance Program (WAP) is a federal program run by the U.S. Department of Energy that pays for home energy efficiency improvements at no cost to eligible households. If your income falls at or below 200% of the federal poverty level, you may qualify for free insulation, window sealing, heating system repairs, and other upgrades that can reduce your utility bills by an average of $372 or more per year. Renters and homeowners both qualify. This guide walks through exactly how to apply, what documents you need, and what income limits apply in 2025.
What Is the Weatherization Assistance Program?
WAP has been running since 1976 and has helped more than 7.2 million low-income families make their homes more energy efficient. The program is federally funded through DOE but administered at the state and local level through a network of nonprofit agencies, community action programs, and local governments.
The work is done by trained contractors and costs you nothing if you qualify. A typical weatherization visit starts with a home energy audit. The auditor identifies where your home is losing energy and prioritizes the most cost-effective improvements. Common upgrades include:
- Attic and wall insulation
- Air sealing and weather-stripping
- Caulking around doors and windows
- Heating and cooling system tune-ups or repairs
- Hot water heater insulation
- LED lighting upgrades
- Low-flow fixtures
- Air duct sealing
The program does not cover cosmetic repairs or upgrades unrelated to energy efficiency. Everything is focused on reducing your energy costs and improving the safety of your home.
Who Is Eligible?
To qualify for WAP, your household income must be at or below 200% of the federal poverty guidelines, or a member of your household must receive Supplemental Security Income (SSI). Some states use the LIHEAP eligibility standard of 60% of state median income (SMI) instead, which may be higher than 200% FPL in certain states.
Households that already receive one of these benefits are typically automatically eligible:
- Supplemental Security Income (SSI)
- Temporary Assistance for Needy Families (TANF)
- LIHEAP (Low Income Home Energy Assistance Program)
- Certain HUD or USDA means-tested programs
The program gives priority to households with:
- Adults age 60 or older
- Members with disabilities
- Children under 18
- High energy usage relative to income
- High energy burden (energy costs that take up a large share of household income)
Both homeowners and renters can apply. If you rent, your landlord must give permission before work begins. Your local agency will typically reach out to your landlord on your behalf as part of the process.

Your state may use higher limits if it has elected to use the 60% SMI standard. Contact your local weatherization agency to confirm the exact limits in your area.
How to Apply for the Weatherization Assistance Program
The application process runs through local agencies, not a federal website. Here are the steps:
Step 1: Find Your Local Weatherization Agency
WAP is delivered through a network of roughly 900 local agencies across the country. These are typically community action agencies or nonprofit organizations. To find yours:
- Go to the DOE's state program map and click your state
- Call your state energy office directly
- Contact your local community action agency
- Call 211, the social services helpline, and ask about weatherization programs
Once you find your local agency, contact them to ask whether they are currently accepting applications. Many agencies maintain waiting lists, so apply as early as possible.
Step 2: Gather Your Documents
Every agency has slightly different requirements, but you will almost always need:
- Proof of income for all household members (recent pay stubs, Social Security award letters, benefit statements, or tax returns)
- Proof of identity (government-issued ID)
- Proof of address (utility bill, lease agreement, or mortgage statement)
- Proof of home ownership or rental agreement
- If a household member receives SSI, SNAP, TANF, or LIHEAP, bring documentation of that benefit
If your household income comes from multiple sources, you may need to document each one separately.
Step 3: Submit Your Application
Take your documents to the local agency or ask if you can submit them by mail or online. The agency will review your income and determine whether you are eligible. If you qualify, your name goes on a waitlist.
Wait times vary significantly by location. Some agencies can schedule services within a few weeks; others have waiting lists that stretch several months. Ask about the typical wait time when you apply.
Step 4: Schedule the Energy Audit
When it is your turn, the agency will contact you to schedule a home energy audit. An energy auditor will visit your home and assess where energy is being lost. They will develop a work plan based on the most cost-effective improvements for your specific home.
You do not pay for the audit or the work.
Step 5: Weatherization Work Is Completed
A contractor approved by your local agency will complete the weatherization work. This may take one visit or several, depending on what improvements are needed. After the work is done, a quality inspector typically reviews the completed work to make sure everything was done correctly.
What Happens After You Apply
After you submit your application, the local agency will confirm eligibility and place you on a list. Here is what to expect:
- You may be contacted for additional documents if anything is missing
- You will receive notice of your eligibility determination
- Once your home is scheduled, you will be given instructions to prepare (such as securing pets or clearing access to the attic and basement)
- The weatherization work itself is typically completed within one visit for smaller jobs, or multiple visits for larger projects
If you are denied, ask the agency about the reason and whether you can appeal or reapply if your situation changes.
WAP vs. LIHEAP: What Is the Difference?
WAP and LIHEAP are separate programs that are often confused because they both help low-income households with energy costs. Here is how they compare:
| Feature | WAP | LIHEAP |
|---|
| What it covers | Physical home improvements | Utility bill payments |
| Who administers it | DOE through state/local agencies | HHS through state agencies |
| Benefit type | Services (not cash) | Direct payment to utility |
| Income limit | 200% FPL or 60% SMI | 150% FPL or 60% SMI (varies) |
| One-time or ongoing | One-time weatherization | Seasonal assistance |
| Requires landlord OK | Yes (for renters) | No |
Many households qualify for both. Getting LIHEAP can also make you automatically eligible for WAP in some states. If you need help with an immediate utility bill while waiting for weatherization services, apply for LIHEAP at the same time.
Other Programs That May Help
If you do not qualify for WAP, or if you are waiting for services, there are other programs worth checking:
- LIHEAP covers heating and cooling bills for low-income households
- HUD HOME program funds home repair grants and loans in some areas
- USDA Section 504 Home Repair helps rural homeowners with home repairs, including energy efficiency improvements
- State-level programs many states have their own weatherization or energy efficiency rebate programs beyond the federal WAP

Frequently Asked Questions
How long does the weatherization process take?
The timeline varies by location and program capacity. After applying, you may wait anywhere from a few weeks to several months before services begin, depending on the local agency's waitlist. The actual weatherization work typically takes one to two days but can be longer for larger homes.
Can renters apply for weatherization assistance?
Yes. Renters can apply, but the program requires written permission from the landlord before any work is done. Your local agency will usually help obtain that permission. Landlords cannot be required to participate, so if your landlord refuses, you may not be able to receive services at your current address.
Does the income limit include all household members?
Yes. The income limit is based on the total gross income of all people living in the household, regardless of whether they are related. This includes wages, Social Security, disability payments, rental income, and other sources.
What if I already receive LIHEAP or SNAP?
Receiving LIHEAP makes you automatically eligible for WAP in many states. SNAP participation does not automatically qualify you, but it is strong evidence of low income. Check with your local agency to confirm.
Is there a cost for weatherization services?
No. All services provided through WAP are free to eligible households. You will not be asked to pay for the energy audit, the labor, or the materials.
What if I live in a mobile home?
Mobile homes are eligible for weatherization services. Eligibility requirements are the same, though the specific improvements may differ based on the construction type of the home.
How do I know if my home was already weatherized?
You can ask your local agency to check program records. In some cases, if a home has already been weatherized through the federal program, it may not be eligible for a second round of services unless significant time has passed or conditions have substantially changed.
Can I apply if I am currently behind on my utility bills?
Yes. Being behind on utility bills does not disqualify you from WAP. In fact, it may help demonstrate a high energy burden, which can increase your priority on the waitlist.
What income counts toward the limit?
Generally, the following are counted: wages and salaries, self-employment income, Social Security benefits, SSI, pension and retirement income, unemployment compensation, and rental income. Some states may count additional sources. Your local agency will tell you exactly what to include.
How do I find my state's weatherization program?
The DOE maintains a directory of state weatherization programs. You can also call 211 or search for your local community action agency. The Benefits USA screener can also point you toward energy assistance programs available in your area.
