Take our quick 30-second assessment to see exactly what rebates your Cambridge home qualifies for.
Start your assessment →In 2026, a Cambridge 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 assessment-required insulation/windows tier.
Cambridge runs on GrandBridge Energy electricity and Enbridge Gas. The province's Home Renovation Savings Program (HRSP) is identical here to the rest of Ontario — the same categories and tiers as Toronto and Ottawa.
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 GrandBridge Energy — 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. Eligible brands: 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.
A typical household stacking a heat pump with solar or battery nets $4,000–$17,000 in direct rebates — identical to Toronto and Ottawa, since this is a provincial program.
We could not confirm a hard expiry date for these programs on the official site as of this writing — check homerenovationsavings.ca directly before relying on any deadline you see elsewhere (several third-party HVAC sites repeat a Nov 30, 2026 date that we could not verify on the official program page).
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 and $780 for cathedral ceiling/flat roof.
A partnership between the Region of Waterloo, GrandBridge Energy, and Reep Green Solutions: low-interest loans up to $40,000 at a 2.5% fixed rate over 10 or 15 years, repaid through your GrandBridge Energy electricity bill. Covers heat pumps, insulation, air sealing, windows and doors, water heaters, smart thermostats, and rooftop solar. Includes a free, independent Energy Coach.
GrandBridge Energy (electricity) + Enbridge Gas (natural gas)
Mostly natural gas
Most Cambridge homes heat with gas furnaces, putting a heat pump switch in the lower HRSP tier.
6–10 weeks quote to installation for solar, faster for a heat pump swap. City building permit + ESA electrical inspection where required.
Most of the rebate figures above assume you own a detached or freehold home and control the whole building. That's not every Cambridge household. Here's what changes if you rent or live in a condo.
The structural HRSP rebates — heat pump, insulation, windows & doors, air sealing — are paid through a contractor application tied to the home and its owner, so those go to your landlord, not you. The smaller purchase-based items on this page, like the $125 smart thermostat rebate and the $25–$200 appliance rebates, are tied to buying the product itself — check the official homerenovationsavings.ca terms to confirm whether you personally qualify to claim one as a tenant. If you want the bigger upgrades, the ask has to go to your landlord — point them to this page.
In-unit upgrades you control yourself — a heat pump water heater, an in-suite heat pump, in-suite windows — may qualify for the rebates above, but anything touching shared systems or the building's exterior typically needs your condo corporation's written approval first, since HRSP applications require proof the work was authorized.
Cambridge's RetrofitWR loan (up to $40,000 at 2.5% fixed, repaid through your GrandBridge Energy bill) is described for individual GrandBridge Energy customers rather than as a multi-unit condo program, so confirm directly with the Region of Waterloo whether a condo corporation can apply on behalf of a whole building. Otherwise, a whole-building retrofit goes through the standard provincial HRSP process, and your condo board or property manager would need to apply, not individual owners.
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 Cambridge 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.
The province's Home Renovation Savings Program doesn't include a cash rebate for home EV charger installs in Cambridge. Check with your electric utility for a separate off-peak charging incentive.
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.
Yes — RetrofitWR offers Cambridge homeowners (as GrandBridge Energy customers) up to $40,000 at a 2.5% fixed rate over 10 or 15 years, repaid via your electricity bill, plus a free Energy Coach. It launched in spring 2026 for GrandBridge customers in Cambridge and North Dumfries.
Most Cambridge homes are on GrandBridge Energy for electricity and Enbridge Gas for natural gas.
