Can you stack heat pump rebates? How to combine them

How stacking works: federal, provincial, utility, municipal

Each level of government, and many utilities, run their own programs, and most were designed knowing the others exist. Stacking means claiming more than one for the same project.

Loans are worth stacking for cash flow, but don’t add them to your “savings”: they are repaid. Our rebate finder keeps loans out of the stacked total for the same reason.

Common exclusions: same-measure rules and caps

Almost every “you can’t combine” rule falls into one of three types.

Same family, same equipment

• In Ontario, rebates from Enbridge, Save on Energy or the Ontario government can’t be stacked on the same heat pump, solar system or attic insulation.
• In B.C., the Home Renovation Rebate and the income-qualified Energy Savings Program can’t both be claimed for the same upgrade.
• In Nova Scotia, an upgrade rebated through the Home Energy Assessment program can’t also be covered by HomeWarming.

Caps on the combined total

• Ontario: heat pump and solar incentives from all sources can’t exceed 100% of the cost; attic insulation can’t exceed 50% of the after-tax cost.
• Nova Scotia: rebates can’t exceed 100% of costs.
• Newfoundland and Labrador’s income-tested TakeCharge program reduces its rebate if another program already covers part of the same project.

Bonus-on-bonus limits

• LogisVert’s rental-building heat pump bonus can’t be combined with its multiple-measures bonus.
• Ottawa’s $600 assessment loan reduction isn’t available if you also receive Home Renovation Savings’ $600 assessment rebate.

Two programs can both be open to you and still refuse to pay for the same heat pump.

Worked examples by province

These use the published rates in our database. They assume a household above any income threshold, an eligible model and a registered installer. The federal line is shown separately because that program isn’t open yet.

In B.C., an electrically heated home replacing baseboards with a whole-home heat pump can get up to $4,000 from the Home Renovation Rebate, and pays no PST on the equipment. BC Hydro’s fall bonus of up to $1,000 more applies only if the install is finished and paid between August 1 and October 31, 2026.

Order of operations: pre-approval, install, claim

Most lost rebates come from doing the right things in the wrong order. This sequence works for nearly every program:

1. Map your programs for your exact address, including city ones.
2. Get every pre-approval first. Nova Scotia’s Moderate Income Rebate needs written approval; B.C.’s Energy Savings Program issues a code valid for three months; Ottawa only counts costs after its Notice to Proceed; Ontario solar needs written pre-approval.
3. Book any required assessment before work starts. Assessment programs only pay for upgrades done after the first visit.
4. Pick a contractor registered with every program you’ll claim, and get the model numbers in writing.
5. Install, pay and document: invoices, proof of payment, nameplate photos, contractor forms.
6. Claim each program in its own window. LogisVert: 9 months. B.C. Home Renovation Rebate: six months from the invoice. Nova Scotia: final assessment within 12 months of the first.

Our finder applies these rules for you: pick your province and the upgrades you’re planning and it lists every program that applies, separates loans from rebates and shows an honest “up to” total.
