Your application paperwork

This is a free, federally funded program that lowers your energy bills by improving your home's energy efficiency. After you qualify, a local agency does a free home energy audit and installs measures like attic insulation, air sealing, and heating system repair at no cost to you. The Washington State Department of Commerce runs it through a network of local agencies, so you apply through the agency that serves your county.

Steps to apply

  1. Confirm you qualify: you live in the home and your household income is within the program limit (commonly at or below 200 percent of the federal poverty level; you are usually automatically eligible if you receive SSI, TANF, or energy assistance).
  2. Find the local weatherization or community action agency that serves your county using the local weatherization agency list on the Commerce website.
  3. Contact that agency and complete its intake application with your income, ownership, and household information.
  4. The agency schedules a free home energy audit to decide which measures your home needs.
  5. The approved energy efficiency measures are installed at no cost to you.
