Do I have to use a contractor?
Yes. All work must be done by an approved BPI-certified participating contractor; work you pay subcontractors for directly doesn't qualify.
Do I need approval before I buy?
Yes. Apply before you buy or install anything; purchases made first don’t qualify. Rebates only cover work done after the home energy audit. Schedule the Home Performance assessment before starting any work.
Is it still available?
Yes. It was open when we last checked, on October 25, 2026.
Do windows or doors qualify for Home Performance rebates?

Can I get a rebate for work I already had done?
No. Rebates apply only to work completed after the home energy audit.
Can I get a second rebate later?
Yes, if the new project covers areas not upgraded before at the same property.
