Hydro One Whole Home Rebates — Ontario 2026

Hydro One's Whole Home program lets Ontario residential customers claim rebates on multiple energy-efficiency upgrades in a single application. Heat pumps, insulation, smart thermostats, and other improvements are eligible. Here is what you need to know to apply.

Frequently Asked Questions

Who qualifies for the Hydro One Whole Home program?

Ontario homeowners who are Hydro One electricity customers and own their primary residence are eligible. Rental properties and landlords may have different requirements — check the Hydro One program page for details.

What upgrades are eligible for Whole Home rebates?

Eligible measures include air-source heat pumps, heat pump water heaters, smart thermostats, attic and wall insulation, air sealing, and window and door replacements. Each measure has its own rebate amount, and combining multiple upgrades in one application maximizes your total rebate.

Do I need a home energy assessment to apply?

An EnerGuide home energy assessment is recommended and may be required for certain upgrades. The assessment helps identify the most impactful improvements and supports your rebate application documentation.

Can Hydro One rebates be combined with other programs?

Yes. Hydro One rebates can often be stacked with the Canada Greener Homes Loan and Enbridge HER+ (for customers who also have Enbridge Gas). Confirm stacking eligibility on the Hydro One website before you apply.
