How it works
What to have ready and what happens next

Have a recent utility bill ready before you start
The form takes a few minutes. You'll answer quick questions about your home type, ownership, and primary heating fuel, then identify your electric and gas providers — and you'll need your utility account number, which is on any recent bill.
- Home type: single-family, apartment, or condominium; and whether you own or rent
- Heating fuel: natural gas, fuel oil, propane, or electric
- Providers: Eversource or United Illuminating for electric; Eversource, CNG, or SCG for gas — plus your account number
We review your submission and contact you to schedule your visit
Eligibility confirmation comes first. Our team reviews your application and confirms whether your household qualifies for HES-IE — open to income-eligible Eversource and UI customers, and to households receiving SNAP, TANF, SSI, or WIC benefits.
- Once eligibility is confirmed, we reach out to schedule your in-home assessment
- The audit is a 2–4 hour visit that includes same-day weatherization improvements
- There is no cost to qualifying households
