What a home energy audit costs in Ontario
Short version: expect $400–$700 for the initial EnerGuide assessment, $200–$400 for the follow-up — and a $600 rebate that covers most of it if you complete Ontario's Home Renovation Savings assessment path.
| Item | Typical price | Notes |
|---|---|---|
| Initial EnerGuide assessment | $400–$700 + HST | Blower door, measurements, rating, upgrade report |
| Follow-up assessment | $200–$400 + HST | Re-test after upgrades; unlocks HRSP rebates |
| Large home surcharge | $50–$150 | Common above ~2,500 sq ft |
| HRSP assessment rebate | −$600 | Paid after completing the assessment path (2+ upgrades) |
| Typical net cost | $0–$400 | When you follow through on the rebate path |
The honest context
NRCan's own guidance pegs a typical evaluation at $600–$1,000 all-in, and prices are almost never published — of the providers in our directory, only a couple post rates openly (for example, Windfall Ecology Centre at $500 + HST initial / $250 follow-up). That opacity is an industry habit, not a law of nature, and it's why we surface published prices first.
Two warnings worth their weight: first, the federal Greener Homes Grant and Loan are closed — any site or salesperson promising them is out of date, including on the cost of "free" evaluations those programs once subsidized. Second, a "free audit" from an insulation or HVAC company is a sales visit, not an EnerGuide assessment — it won't qualify you for the assessment-path rebates, and its recommendations tend to match what the company sells.
Whether the audit pays for itself depends on your home, which is exactly what it measures: audit-guided retrofits of older Ontario homes typically cut total energy use 15–35%. On a $3,000/year energy bill, that's $450–$1,050 a year — every year. Start with the planner to see your likely numbers before you book.
Common questions
How much is a home energy audit in Ontario in 2026?
Typical market pricing is $400–$700 for the initial EnerGuide assessment and $200–$400 for the follow-up visit; NRCan cites a $600–$1,000 typical combined range. Larger homes add $50–$150. The Home Renovation Savings Program rebates $600 after you complete the assessment path, bringing typical net cost to roughly $0–$400.
Why do so few providers publish prices?
Habit, mostly — the industry runs on phone quotes. NRCan itself tells homeowners to expect a wide range. We mark the providers who publish prices and feature them first; transparency is the sort we reward.
Is a "free energy audit" real?
In Ontario, a truly free EnerGuide assessment is rare — free walkthroughs are usually sales visits for insulation, windows, or HVAC. A real assessment includes a blower door test and produces an EnerGuide rating and report from an NRCan-registered advisor. If there is no blower door, it is not the audit the rebate programs require.
What does the price include?
The initial visit: 2–3 hours on site, blower door airtightness test, insulation measurements, window/door inventory, HVAC details, and afterwards your EnerGuide rating, label, and a renovation upgrade report. The follow-up visit re-tests after your upgrades and unlocks the rebates.
