Worked example: one Vermont home

Take 1,000 square feet of attic insulation across 2 large zones, on a project that costs $5,000, in a home heated with oil. These are example inputs, not typical prices. Each program's own rule gives the amounts below; where one program has several tiers only the largest one counts, separate programs add up, and a percentage offer with no cost entered is shown at its ceiling.

UtilityNot income-qualifiedModerate incomeLow income
Green Mountain Power$5,000 max$5,000 max$5,000 max

For a household that is not income-qualified, the example comes to $5,000 at most, made of $5,000 from Efficiency Vermont weatherization. None of the open offers has a separate income-qualified amount, so every household gets the same figure.

Who can use these Vermont offers

Every household in Vermont covered by Efficiency Vermont can apply; the offers are not limited to one utility's territory. None of these program pages lists an end date, and each can change or stop while funds last.

Federal credit and state IRA rebates

The Energy Efficient Home Improvement Credit (IRC §25C) paid 30% of insulation and air-sealing materials, within the $1,200 annual limit (labor not included). The IRS page says: “can claim the credit for improvements made through December 31, 2025.” Not allowed for property placed in service after December 31, 2025.
