How much does the Efficiency Boost (income-qualified multiplier) pay in 2026?

Raises other PSE rebates. Heat pump $1,500 → $2,400 · heat pump water heater $1,000 → $1,100 · smart thermostat $75 → $175. Administered by Puget Sound Energy, verified 2026-09-04 against the program's own published terms.

When does the Efficiency Boost (income-qualified multiplier) expire?

Ongoing. Amounts and deadlines on utility and manufacturer programs change without notice, so we re-check the specific program before a project is committed.

Can the Efficiency Boost (income-qualified multiplier) be combined with other rebates?

Yes — it stacks with Electric Resistance to Air-Source Heat Pump Conversion, Heat Pump Water Heater Rebate, Heat Pump to Heat Pump Upgrade. Stacking is only as good as the program terms in force on your install date, so treat a combined figure as a plan until each program confirms it.

Who files it, and how the money reaches you

Your installing contractor files it. You never see a cheque. The rebate is filed against your project and shows up as a credit on the job, which is why the contractor has to be inside the program network before the work starts.

For heat pumps the installer collects an income attestation on site. For water heaters and thermostats you complete the Efficiency Boost section of the rebate form. There is no separate application and no credit check.

PSE requires a contractor inside its network

PSE pays this class of rebate only when the work is done by a Trade Ally or Recommended Energy Professional — DIY and out-of-network installations are excluded, however good the workmanship. Ask us to confirm network status for your specific project before you count on the money, and get the answer before you sign anything.

What it stacks with

Programs that can sit on top of this one, each with its own conditions.

Stacking is a claim about program terms, not arithmetic. We build totals from the programs that have confirmed they combine, and quote anything unconfirmed as a separate line so you are never counting on a number twice.
