A BPI-certified auditor inspects your home and identifies all available Energize CT rebates. Most Connecticut families qualify for thousands in incentives.
Your home loses energy in ways you cannot see. This audit finds them.
Free for qualifying families. HES-IE is a program for households with a combined gross annual income at or below 60% of the state median. The standard $40 HES copay is waived, and approved insulation projects can qualify for up to 100% coverage of the total cost.
Same thorough audit, deeper incentives. Like the standard HES program, HES-IE provides a comprehensive energy assessment with immediate weatherization that identifies where energy is wasted and recommends upgrades. The difference: income-eligible households receive the most advantageous incentives available.
Who qualifies
Household income at or below 60% of state median
Or meeting your utility's hardship criteria
Owners and renters (landlord approval needed for modifications)
Eversource or UI customers in Connecticut
How HES-IE works
A no-cost path from "do I qualify" to a weatherized home
A Community Outreach Representative guides you through qualification
You do not navigate this alone. HES-IE is for income-eligible Connecticut households, and our Community Outreach Representatives — many of them past customers who accessed these same Energize Connecticut benefits — help you check eligibility, prepare the application, and schedule your appointment so you move directly into the program.
- Representatives are the bridge from finding assistance to booking the audit
- Many reps are past customers with first-hand program experience
- Eligibility check, application prep, and scheduling handled together
The audit is a working appointment — improvements happen the same day
Not a report. A repair visit. BPI-certified technicians arrive with advanced diagnostic tools, measure where your home loses energy, run health and safety checks, then seal leaks and add weatherization on the spot — included at no cost to income-eligible households — so you are not left with a punch list to arrange later.
- BPI-certified technicians with advanced diagnostic tools
- Health and safety checks included in every visit
- Improvements that can be made that day are made that day — at no cost
