How to finance your upgrade
From consultation to completion, here is how Connecticut families finance energy upgrades at 0% interest through Energize CT.
Step 1

Your HCP advisor reviews your project scope and matches you with the right financing program. Three options are available: the 0% HES Payment Plan, the 0% Energy Conservation Loan, and the Smart-E Bundle at 4.99%.

- Program comparisonYour advisor explains each financing option — interest rate, term, loan amount, and payment method.
Step 2
Eligibility and qualification
We determine eligibility on-site based on credit, income, and utility account status. Many families qualify for 0% interest with no credit check required on the HES Payment Plan.

Once approved, your loan is locked in and your project is scheduled. Payments do not begin until the work is complete, so there is no cost while you wait.

- Payment planningFor HES Plan and some Smart-E loans, payments are added to your monthly electric bill — no separate bill.
Step 4
