Weatherization Assistance Program (WAP): Insulation, Heating, and How to Apply

Published: September 5, 2026 | Last updated: September 5, 2026 | Last verified: September 5, 2026

Short answer: The U.S. Department of Energy's Weatherization Assistance Program (WAP) funds no-cost energy-efficiency and related safety work for eligible low-income households. You do not apply on Grants.gov. You apply through a state or local weatherization provider. Owners and renters may qualify; renters need landlord permission. GrantDept.com is not DOE.

Who may qualify

DOE's how-to-apply page (reviewed September 5, 2026) says households at or below 200% of poverty income guidelines, or that receive Supplemental Security Income, are considered eligible under DOE guidelines. Each state or territory may instead use HHS LIHEAP criteria of 60% of state median income. Do not use a blog's dollar table as your limit. Use your state agency's current chart. Priority often goes to elderly household members, people with disabilities, families with children, high energy users, or high energy-burden households.

What WAP may do in the home

A local crew typically starts with an energy audit. Work can include air sealing, insulation, and heating-system safety or efficiency measures the audit justifies. It is not a blank check for a new kitchen. Waitlists are common; some areas take months. WAP is not a same-week shutoff pledge. For bills this month, use LIHEAP. For rural structural repairs (roof, wells, hazards), see USDA Section 504. Hub: housing grants.

How to apply

Read DOE: How to Apply for Weatherization Assistance.
Use DOE's state map or list to find your state weatherization administrator, then the local provider (often a Community Action Agency).
Contact that provider. Many still use phone or in-person intake.
Bring proof of income (pay stubs, Social Security, or other documents they list), identity, a recent utility bill, and home type (house, mobile home, apartment).
If you rent, the provider works with you and the landlord on permission before work starts.

211 can name the local agency if the DOE map is confusing. State human-services hubs: find programs in your state.

Documents

Income for the household the agency counts
Proof of address and who lives in the unit
Recent energy bills
Ownership papers or a lease plus landlord contact for renters

Nobody legitimate charges a fee to "unlock DOE weatherization." Scam warnings. Same-week heat crisis: emergency grants and your utility.

Frequently asked questions

Is weatherization the same as LIHEAP?

No. LIHEAP is mainly help with energy bills and shutoff risk through a state or local office. WAP funds energy-efficiency and related safety work in the home, delivered by a local weatherization provider. Some households may use both. DOE notes states may use LIHEAP-related income rules for WAP.

Can renters apply for WAP?

Yes, both homeowners and renters may apply under DOE guidance. Renters need landlord permission before work begins. The local provider handles that step.

Does GrantDept.com schedule weatherization?

No. Contact your state weatherization administrator or local provider listed on energy.gov.
