Energy Savings and Weatherization Reauthorization Act of 2025

This bill continues the federal Weatherization Assistance Program, which helps low‑income families lower energy bills by making homes more energy‑efficient. It updates program rules, including how a “fully weatherized” home is defined, and replaces older wording about “partially weatherized” units. It also raises certain cost limits so more work can be done per home and lets the Department of Energy increase per‑home limits when prices rise, so projects don’t stall due to market costs .

Key changes include increasing an extra cost allowance from $3,000 to $6,000 for certain measures, updating the cap on average cost per home, and making technical fixes so the law’s cross‑references line up correctly. These changes aim to help more households get effective upgrades like insulation, air sealing, and other energy‑saving improvements .

• Who is affected: Low‑income households seeking home energy upgrades; state and local weatherization agencies that run the program .
• What changes: Program is reauthorized; definition of “fully weatherized” is added; average per‑home cost rules are updated; an extra allowance rises from $3,000 to $6,000; and the Department can raise limits if market conditions require it .
• When: Upon enactment; the bill reauthorizes the program and updates these rules in law text .
