The Weatherization Assistance Program (WAP) provides basic insulation and weatherization measures for low-income households.

The Low Income Home Energy Assistance Program (better known as LIHEAP) is a critical heating and cooling program for low-income Tennessee families. Each year, thousands of families seek assistance from one of 19 nonprofit community or local government agencies that help the Department of Human Services administer these federal dollars. Tennessee households living at or below 200 percent of the federal poverty guidelines are eligible for LIHEAP assistance, as long as funding is available.

Eligibility for LIHEAP assistance is also determined on a priority point system to target households with members who are elderly, disabled and/or under the age of six. LIHEAP assistance does not go directly to the client or applicant; rather direct payments are made through the LIHEAP agency to the local utility company or energy supplier.
