There are two ways to get Ontario’s insulation rebate. One skips the energy assessment (attic only, up to $1,250). The other requires one — and unlocks up to $7,700.
For a lot of Uxbridge homeowners, especially those with older or rural homes, the energy assessment feels like the catch: an extra step, an extra fee, an appointment before you can even start. So they default to the smaller attic-only rebate, or skip the whole thing.
That’s often the wrong call. For an older, leaky, expensive-to-heat Uxbridge home, the assessment isn’t just a hurdle to the bigger rebate — it’s a roadmap that tells you exactly what your house needs and in what order. Here’s what it actually is, and why it usually pays for itself. Verified as of July 2026.
What the energy assessment actually is
An energy assessment is a visit from a registered energy advisor — a certified professional who evaluates your whole home’s energy performance. It’s the same type of assessment behind the EnerGuide home rating system.
It’s not an inspection that can fail you or a sales visit. It’s a measurement and a plan.
What typically happens during it:
- The advisor walks the whole house — attic, walls, basement/crawlspace, windows, doors, heating system
- They often run a blower door test — a fan mounted in a doorway that depressurizes the house so they can measure exactly how leaky it is (this is where air leakage gets quantified)
- They assess your insulation levels throughout
- They enter everything into modelling software
What you get: a Renovation Upgrade Report — a document listing recommended upgrades, each with its energy impact, effectively a prioritized roadmap for making your specific house more efficient.
For an older Uxbridge home where you know something’s wrong but not exactly what, that report is genuinely valuable on its own — never mind the rebate it unlocks.
Why it’s worth the fee (especially for an older/rural home)
There’s a cost for the assessment — ask what it is when you book; it varies by service organisation. Here’s why it usually pays for itself:
1. It unlocks the bigger rebate. The bundled path (up to $7,700 on insulation) requires the before-and-after assessment. Skip it and you’re capped at the $1,250 attic-only rebate. For an older home that needs attic + walls + crawlspace + air sealing, the difference dwarfs the assessment fee.
2. It tells you what to actually do. Older and rural homes have many possible improvements. The report tells you which ones matter most for your house — so you spend on what pays back, not guesswork.
3. It quantifies the air leakage. The blower door test measures something you otherwise can’t see. For a leaky old Uxbridge home, that number is the difference between “add insulation and hope” and “seal the specific leaks that matter.” (This is where whole-home air sealing and AeroBarrier come in — the post-retrofit test verifies the improvement.)
4. It gives you a verified before-and-after. The follow-up assessment confirms what the work achieved — useful for the rebate, and genuinely satisfying to see the leakage number drop.
What the bundled path pays
Every rebate is 50% of what you spend on that measure, up to a cap. For an older Uxbridge home, the measures stack up:
| Improvement | Most you get | Common in older Uxbridge homes? |
|---|---|---|
| Attic | $1,500 | Almost always |
| Exterior walls (drill & fill) | $3,600 | Common — old homes often uninsulated walls |
| Crawlspace | $1,200 | Common under rural homes/additions |
| Basement walls | $1,500 | Common |
| Rim joist | $300 | Almost always |
| Air sealing | $250 | Always — and a big deal in leaky old homes |
| Windows & doors | $100 each opening | If replacing |
$7,700 is the combined cap for insulation. The exterior-wall measure (via drill and fill) is often the single biggest amount available for an older home with uninsulated walls.
And a key point for rural Uxbridge: you do NOT need natural gas to qualify. Homes heated by propane, oil, wood, or electricity that are connected to Ontario’s electricity grid meet the program’s heating requirement. A lot of rural homeowners wrongly assume no gas means no rebate — it doesn’t.
How the assessment fits the whole process
- Book the pre-retrofit assessment — before any work. (This is step one; you can’t start work first.) ⚠️ Starting work before the assessment disqualifies it. The most common mistake.
- Get your Renovation Upgrade Report — your roadmap and your list of claimable measures.
- Complete at least two recommended upgrades (100% coverage where required). ⚠️ Do only one and you get nothing.
- Book the follow-up assessment — same advisor, who re-tests and confirms.
- Rebates issued after the advisor submits.
The attic-only route (if that’s genuinely all you need)
If your home is newer and honestly just needs the attic topped up, the standalone route skips the assessment:
| Existing attic insulation | Most you get |
|---|---|
| R-12 or less | $1,250 |
| Over R-12 to R-25 | $1,000 |
| Over R-25 to R-35 | $800 |
Must reach R-50, whole attic. (This route runs through a closed approved-contractor list — verify independently, see below.)
But for most older Uxbridge homes, the attic is rarely the only thing worth doing — which is exactly why the assessment route usually wins.
Timing
Peak insulation demand runs October–February; energy advisors and contractors both book out. Rural properties can take longer to schedule. Book the assessment in the warm months and the whole sequence — assessment, work, follow-up — runs smoothly before winter. The program can also change or end at any time, so a completed rebate beats a planned one.

Frequently asked questions
What is the energy assessment, exactly? A visit from a registered energy advisor who evaluates your whole home (often with a blower door test), then gives you a report of recommended upgrades. It’s a measurement and a plan, not a pass/fail inspection.
How much does it cost? There’s a fee that varies by service organisation — ask when booking. For a home doing multiple upgrades, it’s usually small next to the extra rebate it unlocks.
Is it worth it for just an attic? If the attic is truly all you’re doing, the attic-only route skips the assessment and may be simpler. If your older home needs more (walls, crawlspace, air sealing), the assessment route pays more and gives you a roadmap.
Do I qualify if I’m on propane with no gas line? Yes — propane, oil, wood, and electric-heated homes on the electricity grid meet the heating requirement. No gas needed.
Can I start work before the assessment? No — that disqualifies it. The pre-retrofit assessment must come first.
Do I need the same advisor for both visits? Yes.
Who gets the rebate? The homeowner — by cheque for non-gas homes, or an Enbridge bill credit for gas customers.
