Connecticut runs its energy efficiency programs through Energize Connecticut — the statewide brand for the ratepayer-funded Conservation & Load Management plan that every electric and gas customer already pays into through a line item on the bill. That money comes back as rebates, no-cost assessments, and low-cost financing, delivered by the utilities: Eversource and United Illuminating on the electric side, and the gas companies for gas measures.
The catch is that “your utility” might not be Eversource or UI at all. Several Connecticut towns — Wallingford, Norwich, Groton, Jewett City, South Norwalk, and Bozrah — run their own municipal electric utilities with their own rebate menus, and they are not part of Energize CT. This page covers the active state, utility, and municipal programs for 2026, for both homeowners and commercial building operators, so you can see what actually applies at your address instead of guessing.

Residential Energy Rebates in Connecticut
For most Connecticut homeowners, the front door to everything else is Home Energy Solutions — an in-home assessment that installs basic weatherization on the spot and sets you up for the equipment rebates that follow. Income-eligible households get the same work at no cost through HES–Income Eligible. From there, the highest-value rebates are tied to heat pumps and insulation.
Energize CT Programs (Eversource & United Illuminating)
Home Energy Solutions (HES / HES-IE)
A technician visits your home, air-seals and installs basic weatherization during the visit, and documents where your energy is going. HES is the qualifying step for most insulation and heat-pump rebates. Income-eligible customers get a no-cost assessment and deeper measures through HES-IE. Start here before buying equipment — it changes what you qualify for.
Who qualifies: Eversource and United Illuminating electric or gas customers. HES-IE is income-based.
Heat Pump Incentives
Connecticut’s heat-pump rebates scale with how far you go. A standard air-source heat pump earns $250 per ton (up to $2,500), but a whole-home “Energy Optimization” installation that displaces your fossil system starts at $1,000 per ton and runs up to $10,000. Ground-source (geothermal) systems earn $1,500 per ton up to $15,000, and heat-pump water heaters get $900. The lesson: partial swaps get partial money — the program pays you to go all the way.
Weatherization & Envelope
Professionally installed insulation earns up to $2.00 per square foot, triple-pane windows $100 each, and heat- and energy-recovery ventilators up to $500. Smart thermostats get up to $85 instant. These are the unglamorous measures that make the heat pump you install afterward smaller and cheaper to run.
Financing
If upfront cost is the barrier, Connecticut has some of the cheapest efficiency money in the country: the CT Heating Loan at 0.99% up to $15,000, Smart-E Loans with no money down through the Connecticut Green Bank, and 0% micro-loans through the HES payment plan. Income-qualified households can access the below-market Energy Conservation Loan.
Solar: Renewable Energy Solutions
Connecticut replaced retail net metering with the Renewable Energy Solutions program, which compensates residential solar owners for the power their system produces plus the renewable energy certificates (RECs) it generates. Rates are set by the program rather than published on a single hub page — your installer models the specific buyback for your system.
Municipal Electric Utilities
If you’re served by a town electric department, Energize CT programs don’t apply — but your utility likely runs its own, and coverage is genuinely good:
Wallingford Electric, Norwich Public Utilities, Jewett City DPU
These municipals offer their own insulation, heating-and-cooling, heat-pump-water-heater, and EV-charger rebates — often on terms comparable to Eversource and UI (for example, up to $2.50 per square foot for attic insulation at Jewett City, and roughly $1,000 in services through Wallingford’s Home Energy Savings Program). Amounts and forms live on each utility’s site; the finder above routes you to the right one.
South Norwalk Electric & Water (SNEW)
SNEW runs a full residential menu — heat pumps ($2,500, or a qualifying heat-pump water heater), attic insulation (up to $2.50 per square foot), electric heating & cooling ($500–$3,000 per ton), EV chargers ($1,500 residential), and new-construction incentives that scale with scope.
State Tax Treatment for Solar & Geothermal
Two statewide provisions apply uniformly, regardless of income or tax situation: Connecticut grants a full sales-and-use tax exemption on qualifying solar and geothermal equipment, and a property-tax exemption (CGS §12-81(57)) so a qualifying renewable system doesn’t raise your assessed value. Both are set by statute — no application tied to your finances.
Federal and other tax incentives may apply depending on your situation; those change frequently and depend on your circumstances, so we don’t estimate them here. Consult a qualified tax professional and see our Federal Incentives page.
Commercial Energy Rebates in Connecticut
Connecticut’s commercial side is deep, and — like the residential side — most of it runs through Energize CT and is delivered by Eversource and United Illuminating. The programs range from no-cost small-business direct-install work to custom incentives worth up to 40% of installed cost on large retrofits, plus a mature C-PACE financing market through the Connecticut Green Bank.
Energize CT Commercial Programs
Small Business Energy Advantage (SBEA)
The best-known entry point for smaller facilities: a no-cost, no-obligation assessment followed by direct-install measures and incentives, with on-bill financing available so the upgrade pays for itself out of the savings. If you run a small commercial building and have never touched an efficiency program, this is where to start.
Energy Opportunities for Existing Buildings
For larger or more complex projects, the Energy Opportunities track offers custom and prescriptive incentives — up to 40% of installed costs — for lighting, HVAC, controls, and process improvements, with the largest projects custom-negotiated against verified savings.
Prescriptive Equipment & Retro-Commissioning
Energize CT publishes a long prescriptive menu: rooftop and heat-pump HVAC, commercial heat-pump water heaters (up to $1,400), controls and thermostats, refrigeration, and a deep bench of commercial-kitchen rebates (fryers, ovens, ice machines, dishwashers). Its Retro-Commissioning program tunes the systems you already own — usually the highest-ROI work available, since it finds savings with no capital replacement — and Express and Instant lighting rebates handle the quick lighting wins.
Financing: C-PACE & C&LM Loans
The Connecticut Green Bank’s C-PACE lets commercial owners finance efficiency and renewable projects through a benefit assessment on the property-tax bill, repaid over the life of the equipment and transferable when the building sells. Energize CT also offers low-interest C&LM loans for small-business and municipal projects.
Federal Tax Provisions
Federal energy tax credits changed sharply in 2025 — most residential credits ended after December 31, 2025, while some commercial incentives run into 2026. We keep the current details on our Federal Incentives page; confirm your situation with a qualified tax professional.
Commercial Projects: Work With an Energy Professional
Most commercial Energize CT applications require pre-approval before work begins, an assessment to document baseline conditions, and post-installation verification. Running that process while managing a capital project is a real time commitment for an internal facilities team — and starting work before approval can forfeit the incentive entirely.
GetEnergyRebates.com connects Connecticut commercial building owners and facility managers with regional energy professionals — energy auditors, LED and HVAC installers, and efficiency consultants with direct experience processing Eversource and United Illuminating incentive applications.

Frequently Asked Questions
Are Energize CT and my utility’s rebates the same thing?
Yes. Energize CT is the statewide brand for Connecticut’s ratepayer-funded Conservation & Load Management programs, delivered by the utilities — Eversource and United Illuminating on the electric side, and the gas utilities for gas measures. Applying through your utility’s program is applying through Energize CT; you don’t stack the two against each other. Where a separate incentive exists (for example a manufacturer rebate or CT Green Bank financing), verify the terms with each administrator before applying.
Do Connecticut commercial rebates require pre-approval before starting work?
Most large commercial incentives do. Energize CT’s custom and larger prescriptive tracks generally require you to submit an application and receive an incentive commitment before you begin the project. Starting work before that approval typically disqualifies it — one of the most common and costly mistakes on commercial rebate applications. Confirm the pre-approval requirement with Eversource or United Illuminating before you order equipment.
What’s the best starting point for a commercial efficiency project in Connecticut?
Start with an energy assessment. For most facilities the right first step is a scoping audit that identifies the highest-value measures, creates the documentation base for Energize CT incentive applications, and gives you an independent analysis to take to your CFO. Smaller businesses may qualify for Energize CT’s Small Business Energy Advantage track, which offers a streamlined, direct-install path. Sizing the work to an assessment first almost always beats leading with a single equipment swap.
What about federal tax credits?
Federal and other tax incentives may apply depending on your situation; those change frequently and depend on your circumstances, so we don’t estimate them here. Consult a qualified tax professional and see our Federal Incentives page.
