Planning a heat pump installation in Ottawa, or just trying to make your home more energy efficient? This page covers every energy rebate in Ottawa in one place.
Take our quick 30-second assessment to see exactly what rebates your Ottawa home qualifies for.
Start your assessment →In 2026, an Ottawa homeowner can claim up to $12,000 for a heat pump, $10,000 for solar + battery combined, up to $1,250 for attic insulation, $125 for a smart thermostat, and up to $200 per appliance — on top of a separate $7,700 assessment-required insulation/windows tier and the City's Better Homes Ottawa loan.
Ottawa runs on Hydro Ottawa electricity and Enbridge Gas. The provincial Home Renovation Savings Program (HRSP) is identical here to the rest of Ontario — the same rebate categories and tiers as Toronto — with Ottawa's own financing program layered on top instead of a cash top-up.
Enbridge Gas customers switching from gas: up to $2,000 (air-source) or $3,000 (ground-source). Switching from electric, oil, propane, or wood: up to $7,500 (air-source) or up to $12,000 (ground-source).
$1,000/kW, capped at 50% of total cost. Choose this rebate or net metering with Hydro Ottawa — not both.
$300/kWh, capped at 50% of cost. Stacks with the solar rebate for up to $10,000 combined.
Amount scales with your starting R-value: up to $1,250 from ≤R-12, $1,000 from R-12–25, $800 from R-25–35.
Instant rebate before you buy, or mail-in after. Same eligible brands as the rest of Ontario: ecobee, Google Nest, Honeywell Home, Copeland Sensi, Mysa, and Sinopé.
Heat pump dryer $200, induction cooktop/range $150, washer $75, fridge $50, freezer $50, dishwasher $25.
City-run financing at 4.33% fixed over 20 years, repaid via your property tax bill. Natural gas-powered upgrades are excluded.
A typical household stacking a heat pump with solar or battery nets $4,000–$17,000 in direct rebates — identical to Toronto, since this is a provincial program. The Better Homes Ottawa loan is where Ottawa differs most from Toronto: a single 20-year/4.33% rate instead of multiple term options, a 4% admin fee, and gas upgrades explicitly excluded from what it will finance.
We could not confirm a hard expiry date for the HRSP rebates on the official site as of this writing — check homerenovationsavings.ca directly before relying on any deadline you see elsewhere.
Same structure as the rest of Ontario: a home energy assessment (about $600, refunded as a rebate), at least two qualifying upgrades, and an extra $500 bonus for completing three or more.
To at least R-20 across 100% of exterior wall area.
Plus Basement Slab (up to $500) and Foundation Header (up to $300) as separate, smaller sub-categories.
Crawlspace wall up to $1,200, plus crawlspace ceiling up to $1,200 — two separate measures.
Per rough opening replaced with an eligible ENERGY STAR window or door.
Replaces a gas, electric, or oil tank.
Draftproofing your home's envelope, verified by the before/after assessment.
Attic and cathedral-ceiling insulation are available on the no-assessment path above (up to $1,250 / $750), but the same work pays more if bundled into this assessment-required tier instead: up to $1,500 for attic (from a starting point of R-12 or less) and $780 for cathedral ceiling/flat roof. If you're already doing an assessment for other upgrades, do attic insulation here rather than through the standalone no-assessment path.
The Better Homes Ottawa Loan Program is financing, not a rebate — low-interest money tied to your property, repaid through your property tax bill. It's delivered by EnviroCentre, an Ottawa-based non-profit, on behalf of the City.
Covers thermal envelope upgrades (insulation, air sealing, windows, doors, green roofs), heat pumps (air-source and ground-source), thermostats, ventilation, water heating (including solar and heat recovery), solar panels, Level 2 EV chargers, battery storage, water efficiency measures, and some health/safety and climate-adaptation work.
Hydro Ottawa (electricity) + Enbridge Gas (natural gas, ~3 in 4 homes)
Mostly natural gas
Similar to Toronto — most Ottawa homes heat with gas, putting a heat pump switch in the lower HRSP tier, with the Better Homes Ottawa loan available for the rest (except the gas system itself).
Reliable, with real winter storm risk
Ottawa sees more severe winter ice storms than Toronto, making battery backup a more practical resilience play here.
Quote to installation: 6–10 weeks for solar, faster for a straight heat pump swap
Permits: City building permit + ESA electrical inspection where required
Better Homes Ottawa loan approval: Apply before hiring a contractor — funding must be approved first, and delivery partner EnviroCentre handles the application
Rebate payout: Typically 30–60 days after your contractor or the assessment advisor submits documentation
Most of the rebate figures on this page assume you own the home outright and control the whole building. That's not everyone in Ottawa. Here's what changes if you rent or live in a condo:
The HRSP rebates above go to whoever pays for and owns the upgrade — typically your landlord, not you. If you want a heat pump, insulation, or solar added to the property, the ask has to go to your landlord; point them to this page and the official homerenovationsavings.ca program page so they can apply directly.
In-unit upgrades you control yourself — a heat pump water heater, a smart thermostat, in-suite windows — may still qualify for the HRSP rebates above, but anything touching shared systems or the building's exterior typically needs your condo board's written approval first. Get that approval before applying, since the rebate paperwork can ask for proof the work was authorized.
Heat pumps, insulation, or solar for an entire building are a group decision that goes through the condo board rather than an individual owner. The Better Homes Ottawa loan described above is aimed at single-family homeowners; this page doesn't establish a separate multi-unit or condo-board application path for it, so a condo board should confirm directly with the program before assuming it applies. The safest first step for a board is the official HRSP program finder above, or contacting the program directly to ask what a multi-unit building qualifies for before assuming the single-family numbers on this page apply.
These are the real, published rebate amounts from this page, organized by category so you can jump straight to what you're planning. Filter below.
Depends what fuel you're switching from: gas customers get up to $2,000 (air-source) or $3,000 (ground-source); switching from electric, oil, propane, or wood gets up to $7,500 (air-source) or $12,000 (ground-source). Province-wide, same in every Ontario city.
$1,000/kW, capped at 50% of cost. Combined with battery, a typical Ottawa household can net up to $10,000 for solar + battery together. You choose this or net metering, not both.
$300/kWh, capped at 50% of cost. Stacks with the solar rebate above.
Scales with starting R-value: up to $1,250 from ≤R-12, $1,000 from R-12–25, $800 from R-25–35. Cathedral ceiling/flat roof up to $750.
Exterior wall to at least R-20, up to $3,600. Plus foundation/basement wall up to $1,500, crawlspace up to $2,400, and exposed floor $300 as separate measures — needs a before/after energy assessment ($600, refunded as a rebate) plus 2+ qualifying upgrades.
Replaces a gas, electric, or oil tank. Part of the assessment-required tier.
Per rough opening replaced with an eligible ENERGY STAR window or door. Part of the assessment-required tier.
There's no HRSP cash rebate for a home EV charger. In Ottawa, an EV charger install is an eligible expense under the City's Better Homes Ottawa loan ($10,000–$125,000, fixed 4.33%, repaid through your property tax bill).
Instant or mail-in. Eligible brands include ecobee, Nest, Honeywell, Mysa, and Sinopé.
It depends on the heat pump type and your current fuel. Enbridge Gas customers switching from gas get up to $2,000 for an air-source unit or $3,000 for ground-source. Households switching from electricity, oil, propane, or wood get up to $7,500 for air-source or up to $12,000 for ground-source. This is the same provincial HRSP structure as the rest of Ontario.
A City of Ottawa loan of $10,000 to $125,000 (or 10% of your property's assessed value, whichever is lower), at a fixed 4.33% rate over a 20-year term, repaid through your property tax bill. A 4% administrative fee applies. It covers heat pumps, insulation, windows, solar, battery storage, and EV chargers — but natural gas-powered upgrades are explicitly excluded.
Most Ottawa homes are on Hydro Ottawa for electricity and Enbridge Gas for natural gas, which serves roughly 3 in 4 Ottawa homes.
No. The program explicitly excludes natural gas-powered upgrades — it's meant to finance the switch away from gas, not a like-for-like gas replacement. A gas furnace upgrade would need to rely on Enbridge Gas's own rebate programs instead.
Only if your household qualifies for the income-based Energy Affordability Program, which can install a smart thermostat for free. Everyone else can get $125 back from Home Renovation Savings, plus $75 (then $20 a year) from Save on Energy's Peak Perks if the thermostat controls central air or a heat pump.
Yes. The City sets aside 0% loans for households at or below its income limits. Others pay the standard fixed rate over 20 years.
