What Cambridge homeowners can claim — no assessment needed

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, $100 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.

🔥 Heat Pump

$2,000–$12,000

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).

☀️ Solar Panels

up to $5,000

$1,000/kW, capped at 50% of total cost. Choose this rebate or net metering with GrandBridge Energy — not both.

🔋 Battery Storage

up to $5,000

$300/kWh, capped at 50% of cost. Stacks with the solar rebate for up to $10,000 combined.

🌡️ Attic Insulation

up to $1,250

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.

🌡️ Smart Thermostat

$100

Instant rebate before you buy, or mail-in after. Eligible brands: ecobee, Google Nest, Honeywell Home, Copeland Sensi, Mysa, and Sinopé.

📦 Appliances

$25–$200

Heat pump dryer $200, induction cooktop/range $150, washer $75, fridge $50, freezer $50, dishwasher $25.

Honest math for Cambridge

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).

Bigger renovation, bigger rebates

Assessment-required rebates — the deep-retrofit tier

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.

🌡️ Exterior Wall

up to $3,600

To at least R-20 across 100% of exterior wall area.

🌡️ Foundation / Basement Wall

up to $1,500

Plus Basement Slab (up to $500) and Foundation Header (up to $300) as separate, smaller sub-categories.

🌡️ Crawlspace

up to $2,400

Crawlspace wall up to $1,200, plus crawlspace ceiling up to $1,200 — two separate measures.

🌡️ Exposed Floor

$300

🟫 Windows & Doors

$100/opening

Per rough opening replaced with an eligible ENERGY STAR window or door.

💧 Heat Pump Water Heater

$500

Replaces a gas, electric, or oil tank.

🌬️ Air Sealing

$200–$250

Draftproofing your home's envelope, verified by the before/after assessment.

Attic insulation pays more if you bundle it here

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.

FAQ for Cambridge residents
