Efficiency Vermont is the nation's first energy efficiency utility, established in 2000. This guide covers every program available to Vermont homeowners in 2026 -- from free phone assessments and insulation rebates to heat pump incentives and income-eligible benefits.
Updated February 2026
Efficiency Vermont (EVT) is not a utility company. It is the nation's first energy efficiency utility, established in 2000 as an independent entity that helps Vermont homeowners and businesses reduce energy costs. Think of it as Vermont's version of Mass Save in Massachusetts or Energize CT in Connecticut -- but EVT was the original, and the model that other states followed.
EVT is administered by Vermont Energy Investment Corporation (VEIC), a mission-driven organization that manages the day-to-day operations including scheduling assessments, processing rebates, and coordinating with contractors. EVT operates under contract with the Vermont Public Utility Commission (PUC), which provides regulatory oversight and sets performance targets.
Unlike programs in most states that are run by utility companies themselves, EVT serves ALL Vermont electric customers regardless of utility. Whether you get your electricity from Green Mountain Power, Vermont Electric Cooperative, Burlington Electric Department, or any of Vermont's 17 municipal utilities, you are eligible for every EVT program.
Funding comes from an energy efficiency charge on all Vermont electric bills -- roughly ~$0.009/kWh. This means every Vermont electric customer is already paying into the program. If you pay a Vermont electric bill, you are eligible for EVT services.
Every program available to Vermont homeowners in 2026. Click any card for the full deep-dive guide with step-by-step instructions, eligibility details, and cost breakdowns.
Free phone assessment or $100 on-site comprehensive audit with blower door test, thermal imaging, and free installations worth $195-$500.
Attic, wall, basement, and air sealing. 75% off for all customers (up to $4,000). 100% off for income-eligible households.
Cold-climate air-source heat pump rebates. $800/unit standard or $3,000/unit income-eligible through EVT.
Heat pump water heaters use 60-70% less electricity. $300 standard or $600 premium (UEF 3.5+) rebate from EVT.
Enhanced benefits for qualifying low-income households. Free audit, free insulation, $3,000/unit heat pump rebates.
Total installed cost breakdown by system type after EVT rebates. Ductless, ducted, and ground-source pricing.
Every EVT program offers enhanced benefits for income-eligible households. Here is a side-by-side comparison of what each tier provides.
All VT electric customers regardless of income
At or below 80% AMI or enrolled in qualifying programs
Also eligible if enrolled in LIHEAP, 3SquaresVT (SNAP), Reach Up (TANF), SSI, Medicaid/Dr. Dynasaur, Section 8, or WAP.
Key distinction: EVT rebates are direct rebates funded by Vermont ratepayers, not federal tax credits. They are unaffected by the federal expiration and remain fully available in 2026. The energy audit, 75% insulation discount, heat pump rebates, and HPWH rebates all continue as normal.
Efficiency Vermont serves ALL electric customers regardless of utility. Here is how Vermont's utilities break down -- same EVT rebates apply to every one.
Largest VT utility — serves ~70% of VT electric customers across most of the state
Northeast Kingdom, Lamoille, and parts of Franklin and Grand Isle counties — serves ~15% of VT
City of Burlington only — serves ~8% of VT electric customers
Central VT — parts of Washington, Orange, Caledonia counties — serves ~4% of VT
Swanton, Lyndonville, Morrisville, Northfield, Stowe, Hardwick, Ludlow, Barton, Orleans, Jacksonville, Hyde Park, Johnson, and others. All served by Efficiency Vermont.
Button-Up Vermont is EVT's annual weatherization campaign, typically running October through December. It is not a separate program with different rebates -- it is a marketing and education initiative that drives awareness of existing EVT insulation and weatherization rebates during the critical pre-winter season.
Vermont is entirely IECC Climate Zone 6 -- among the coldest in New England. With roughly 7,700 heating degree days, insulation is more critical here than almost anywhere in the lower 48 states. Many pre-1970 farmhouses have little or no wall insulation.
Efficiency Vermont (EVT) is the nation's first energy efficiency utility, established in 2000. It is NOT a utility company -- it is an independent entity administered by the Vermont Energy Investment Corporation (VEIC) under contract with the Vermont Public Utility Commission (PUC). EVT serves ALL Vermont electric customers regardless of which utility provides their electricity (GMP, VEC, BED, or municipal). Funding comes from an energy efficiency charge on all VT electric bills, roughly $0.009 per kWh.
EVT offers two options: a FREE phone assessment (30-60 minutes) that reviews your energy bills and identifies quick improvements, and a comprehensive on-site audit ($100 copay, 4-6 hours) that includes blower door testing, thermal imaging, and free installations worth $195-$500 (LEDs, smart thermostat, showerheads, pipe insulation). Income-eligible households pay $0 for both. The on-site audit is required before receiving insulation rebates.
Standard customers receive 75% off insulation and air sealing, up to $4,000 per project. Income-eligible households (at or below 80% AMI) receive 100% off -- completely free insulation. An on-site energy audit is required first. The rebate is typically applied as an instant discount at installation, not as a reimbursement. Work must be done by an EVT participating contractor.
Standard EVT heat pump rebate is $800 per unit for qualifying cold-climate heat pumps. Income-eligible households receive $3,000 per unit -- nearly 4x the standard rebate. There is no federal 25C tax credit available in 2026 (it expired December 31, 2025), so the EVT rebate is your primary incentive.
No. The federal Section 25C energy efficiency tax credit (heat pumps, insulation) and Section 25D residential solar tax credit both expired December 31, 2025. They provide $0 in 2026. EVT rebates are direct rebates funded by Vermont ratepayers, not federal tax credits, so they are unaffected by the expiration and remain fully available in 2026.
You qualify if your household income is at or below 80% Area Median Income (AMI). For a household of four in Vermont, this is approximately $66,950 per year. You also qualify automatically if you are enrolled in LIHEAP, 3SquaresVT (SNAP), Reach Up (TANF), SSI, Medicaid/Dr. Dynasaur, Section 8, or the Weatherization Assistance Program. Call 888-921-5990 to check your eligibility.
No. Efficiency Vermont is an independent energy efficiency utility -- it is not a power company. Green Mountain Power (GMP) is an electric utility that generates and delivers electricity to about 70% of Vermont. EVT serves ALL Vermont electric customers including GMP, VEC, BED, and municipal utility customers. GMP has some additional programs (Tesla Powerwall leasing, eHeat rate), but EVT rebates apply regardless of your utility.
