How Washington's rebates are organized
Washington is a state of many utilities, and many of them are public. Seattle City Light and Tacoma Power are owned by their cities, and Clark Public Utilities is a public utility district. Puget Sound Energy and Avista are investor-owned. Each sets its own rebates, so the same heat pump can earn $300 in one city and $2,000 in another. The US Census Bureau's American Community Survey (2020 to 2024) shows that electricity is the leading main heating fuel in Seattle, Tacoma, Vancouver and Bellevue, and gas leads in Spokane.
- Puget Sound Energy: heat pump $1,500, water heater $1,000, insulation, windows and more. See Bellevue.
- Seattle City Light: heat pump discount of $300 to $600 and a water heater rebate of $750. See Seattle.
- Avista: insulation at $1.75 per square foot and up to $225 per window. See Spokane.
- Tacoma Power: up to $2,000 for a heat pump with zero percent loans. See Tacoma.
- Clark Public Utilities: $1,500 for a water heater and up to $1,250 for a heat pump. See Vancouver, Washington.
Statewide programs that apply no matter your utility
Four things sit above the utilities. The first is the state's Home Electrification and Appliance Rebates program, which works through local partners and is for households at or below 150 percent of area median income. The second is the federal-funded HOMES and HARP rebates, which the State Department of Commerce says have not launched. The third is the state sales tax exemption on solar equipment and installation, which runs through 2029. The fourth is the federal tax credits, which ended after 2025. Our Washington state programs guide explains all four. For categories where every city in the state follows the same rule, read our guides to solar, batteries, EV chargers and smart thermostats.
Rebate finder, by category
Heat pumps: Seattle, Spokane, Tacoma, Vancouver, Bellevue.
Heat pump water heaters: Seattle, Spokane, Tacoma, Vancouver, Bellevue.
Insulation: Spokane, Tacoma, Vancouver, Bellevue.
Windows and doors: Spokane, Tacoma, Vancouver.
Seattle City Light has no insulation or window rebate on the pages we read, so Seattle has no page for them. Puget Sound Energy does have window and insulation rebates, and the Bellevue hub lists them.
What we could not confirm
We could not confirm a per-household dollar amount for the state's home electrification rebates, because each local partner sets its own. We could not confirm the cut-offs between Puget Sound Energy's two window rebate levels, and its washer and dryer page shows two sets of amounts that do not match. We did not read the income limits for Avista's free weatherization program or Puget Sound Energy's income table. Each page on this site says what it could not read.
Renters and condo owners
Most utility rebates on this site are for single-family homes and are claimed by the person who pays for the equipment. In Seattle and Bellevue about half of households rent, so many readers need their landlord to agree. The state's home electrification program is open to renters at or below 150 percent of area median income through local partners. Tacoma Power's EV charging credits are open to renters too. For everything else, ask your landlord to read the city page for your utility, and ask the utility whether a rental home qualifies, since several pages we read do not say.
Quick Questions
Read the questions and answers
Is there a Washington statewide rebate for heat pumps?
Not one set amount. The state funds local partners that give rebates to households at or below 150 percent of area median income, and each utility has its own heat pump rebate.
Which Washington utility pays the most for a heat pump?
On our October 6, 2026 reading, Tacoma Power pays up to $2,000, Puget Sound Energy pays $1,500 to $4,000 depending on income and fuel, and Clark Public Utilities pays up to $1,250. Seattle City Light and Avista give contractor discounts of $300 to $600.
Is the federal tax credit still available?
No. The IRS says the residential clean energy credit does not apply to property placed in service after December 31, 2025, and the home improvement credit covers improvements through that date.
Is solar taxed in Washington?
Solar equipment and installation for systems up to 100 kilowatts are exempt from sales tax from July 1, 2019 through December 31, 2029.
How do I know which utility serves me?
Look at the top of your electric or gas bill. If you are unsure, call the city or county where you live.
