Washington Rebate Calculator 2026: What Your Utility Pays
Pick your utility and what heats your home, and see which Washington utility rebates fit, with a source for every number.
Short answer: Washington has no single statewide rebate, so the money depends on your utility. Heat pump water heaters pay $500 to $1,500, heat pumps pay up to $2,000, and several utilities pay for insulation, windows and thermostats. The federal credits ended after 2025 and the federal-funded state rebates have not launched.

Common questions
Why do I choose a utility?
Washington has no statewide home rebate for most upgrades. Each utility sets its own amounts, so your utility decides what you can claim.
Why are some amounts shown but not counted?
Per-window and per-square-foot rebates depend on your real measurements, so we show the rate but do not add a guess to the total.
Is there a federal tax credit?
No. The IRS says the residential clean energy credit does not apply after December 31, 2025, and the home improvement credit covers improvements through that date.
What about the state's income-based rebates?
The state's home electrification rebates run through local partners for households at or below 150 percent of area median income. No statewide dollar amount is published, so the calculator does not count them.
