Quick answer
Ontario homeowners can get up to $1,250 back for upgrading attic insulation through the Home Renovation Savings Program, a provincial energy-efficiency program in Ontario. The rebate is 50% of your after-tax cost, up to a maximum that depends on how much insulation you have today. Your whole attic must reach at least R-50, and the work must be finished by November 30, 2026.
How much can you get?
The rebate depends on one thing: how much insulation is in your attic right now. The less you have, the more you can get back. Your contractor measures this during an in-home visit before any work starts.
| Your attic today | You must upgrade to | Maximum rebate |
|---|---|---|
| R-12 or less (about 3–4 inches) | R-50 or more | $1,250 |
| More than R-12, up to R-25 | R-50 or more | $1,000 |
| More than R-25, up to R-35 | R-50 or more | $800 |
| Cathedral ceiling / flat roof, R-12 or less | R-20 or more | $650 |
| Cathedral ceiling / flat roof, R-25 or less | R-28 or more | $750 |
The 50% rule, in plain numbers
You get back half of what you paid after tax, but never more than your maximum. Two examples:
- Your attic has R-10 today. The job costs $2,825 after tax. Half is $1,412, which is more than the $1,250 maximum, so you get $1,250.
- Your attic has R-20 today. The job costs $1,400 after tax. Half is $700, which is under the $1,000 maximum, so you get $700.

Who qualifies
You are likely eligible if all of these are true:
- You own the home (landlords can apply for rentals).
- It is a detached or semi-detached house, row house, non-stacked townhouse, or a mobile home on a permanent foundation.
- It is heated mainly by a natural gas furnace or boiler, or by electricity, oil, propane or wood with power from an Ontario utility.
- Your attic has R-35 or less today.
- Nobody has received an attic insulation rebate for this address before (for example through the older Home Efficiency Rebate or HER+ programs).
Not eligible
Brand-new homes (less than 6 months lived in), apartment buildings, duplexes and triplexes, and stacked townhomes. Homes built as single-family houses that later added a basement suite can still qualify.
How to claim it, step by step
- Pre-register on the official site, homerenovationsavings.ca.
- Book an in-home visit with an insulation contractor on the program’s participating contractor list. They measure your current insulation. This sets your rebate tier.
- Sign the program terms and schedule the work.
- Insulate 100% of the attic to at least R-50 (new insulation goes where the old insulation is, usually the attic floor).
- Send your documents: the invoice and a copy of your property tax bill. Keep copies of everything.
- Your contractor enters the job in the program system. Then your rebate is paid.
Mistakes that cost people their rebate
- Starting work before the in-home visit. Anything installed before the contractor’s visit does not qualify.
- Using a contractor who is not on the participating list. Ask for proof before you sign.
- Only doing part of the attic. The whole attic area must be upgraded.
- Stopping short of R-50. If the final level is under R-50, there is no rebate.
- Leaving it too late. Installation must be done by November 30, 2026, and funding can end earlier.
Good to know
The rebate pays for insulation only. Work like removing contaminated insulation, sanitizing after wildlife, or fixing ventilation is not covered, so ask for a quote that shows each item separately.
Frequently asked questions
Do I need an energy audit first?
Not for this attic-only rebate. There is a separate path in the same program that starts with a home energy assessment and covers more upgrades, such as windows, walls and heat pumps.
Can I do it myself and still get the rebate?
No. The work must be done by a participating insulation contractor.
What if I already got an energy rebate before?
If that rebate was for attic insulation at the same address, you cannot get a second one. A rebate for something else, like a furnace, does not block you.
Is the rebate available in 2027?
The current terms end November 30, 2026, and no extension has been announced. Check homerenovationsavings.ca for updates.
