Energize Connecticut is the state’s energy efficiency program, funded through your utility bill. For insulation, it pays a rebate for every square foot that meets the program’s R-value targets, based on the area our crew measures and installs.
| 2026 program | What you get |
|---|---|
| Rebate rate | Up to $2.00 per sq ft |
| Most per home | $10,000 |
| Rebate limit | Up to 75% of the installed cost |
| Income limit | None |
| Home Energy Solutions visit | $40 |
Rates and limits are set by Energize CT and can change each program year; see the official Energize CT insulation rebate page.
The rebate is paid for every square foot of insulation we install in an under-insulated part of your home, in any Connecticut town. It is capped at 75% of the installed cost and at $10,000 per home.
Example: raising 1,000 square feet of attic floor from about R11 to R49 earns up to $2,000, provided that is no more than 75% of the invoice. Add the walls, rim joists or a basement ceiling and each area adds to the total.
Attics, exterior walls, basement and garage ceilings and rim joists all qualify when they fall below the program’s insulation levels. Each area is measured and paid separately, so insulating the whole house can earn far more than the attic alone.
Not sure where your home stands? We check every area during the free inspection and show you the expected rebate for each one before you spend anything.
Any under-insulated surface between your heated or cooled rooms and unconditioned space can qualify, in any Connecticut town. What counts is how much insulation is there now and the R-value it reaches, not the type of material.
Each area has two tests. The insulation already there must be at or below a set level, and the finished insulation must reach a minimum R-value.
| Area | Existing insulation | Finished R-value |
|---|---|---|
| Attic floor | R19 or less | R49 (R38 where R49 won’t fit) |
| Floored-over attic | R4 or less | R19 |
| Walls, above or below grade | R4 or less | R13 |
| Basement & garage ceilings | R6 or less | R19 |
| Rim joists | R6 or less | R13 |
An attic that already has more than R19 won’t qualify for more attic insulation, but its walls, rim joists or basement ceiling still might. We check every area during your inspection.
Most Connecticut homes qualify.
Homes with Eversource or United Illuminating electric service, or Connecticut Natural Gas or Southern Connecticut Gas heat.
Single-family homes, two-families and small buildings with up to four units.
Homeowners qualify, and renters can too with written approval from the landlord.
The rebate isn’t based on household income, so every qualifying home can get up to $2.00 per square foot.
Cloud9 is an approved Energize CT insulation contractor and a member of the Connecticut Insulation Installers Network, so our installations qualify for the program.
We measure each area, prepare the itemized invoice the program requires and submit the final paperwork after installation. In some cases, the rebate can come off your invoice up front.
Your proposal shows the price and the expected rebate for each area, so you know your cost before any work begins.
Yes. The Home Energy Solutions visit comes first, and the insulation has to be recommended during that visit. We can explain how to schedule it.
Yes, under the same rules as every other material. Closed-cell foam, open-cell foam, blown-in fiberglass or cellulose, batts and rigid board all qualify when they meet the R-value target in an area next to heated or cooled space.
The program multiplies the square feet of qualifying insulation by the rebate rate, up to $2.00 per square foot. The total can’t exceed 75% of the installed cost or $10,000 per home.
No. The rebate isn’t based on income, so homeowners and renters at every income level can use it, as long as the home is under-insulated.
No. As an approved contractor, we prepare and submit the rebate paperwork on your behalf. You only sign where the program requires the homeowner’s signature.
In some cases, yes. We take the rebate off your invoice up front and you sign the rebate over to Cloud9, so you don’t have to wait for the program to pay you. We’ll tell you during the estimate whether your project can be handled this way.
No. Energize CT is a Connecticut program for Connecticut utility customers.
