Make your home more energy efficient

Make your home more energy efficient. Check your local provider’s programme, service area and current instructions.

Before you start

Choose your county on the map, then check the named provider and its city or ZIP service area. A county referral is a starting point; it does not establish eligibility at your address.
Bill assistance, crisis assistance and weatherization are different services. Some counties use separate providers for bills and home improvements.
Funding is limited. Meeting an income guideline or receiving help in a previous year does not guarantee a payment. Continue to contact your utility about payment arrangements and disconnection.
Check current application channels before visiting. Some providers accept only online or mailed applications; telephone hours, public visits and appointment times can differ.
