Enbridge Gas incentives for commercial buildings: what pays, and how to get it
Enbridge pays toward the audit, the equipment and the savings. Most of it needs approval before you buy, which is where most owners lose the money.
THE SHORT ANSWER
- The audit: up to 50% of an energy assessment, to $6,000, $10,000 or $20,000
- The equipment: fixed rebates per unit, such as up to $18,000 for a hybrid rooftop unit
- The savings: up to $0.40 per cubic metre of gas saved, to $100,000 per project
- The catch: most of it needs Enbridge's approval before you buy
The four Enbridge programs for buildings
| Program | What it pays | Best for |
|---|---|---|
| Energy Assessments and Meters | Up to 50% of an audit, air balancing, benchmarking, thermal survey or steam trap audit; max $6,000 / $10,000 / $20,000 by annual gas use | Finding the savings, and the gas-saving numbers the other programs ask for |
| Prescriptive Incentive Program | Set amounts per unit: hybrid rooftop units up to $18,000, condensing make-up air up to $14,000, energy recovery ventilators up to $8,000, heat recovery ventilators up to $5,000, air curtains up to $6,000 | Replacing standard equipment with efficient models |
| Commercial Custom Retrofit | Up to $0.40 per m³ of gas saved, up to 75% of the extra cost, to $100,000 per project ($500,000 institutional) | Boilers, controls, heat recovery and envelope projects |
| Affordable Housing Multi-Residential | Enhanced custom incentives (up to $2.50 per m³, to $200,000 per project under 2026 terms), prescriptive rebates and free heat reflector panels | Non-profit, co-op and private affordable housing |

The order that keeps the money
- Benchmark first. See whether the building's gas use is high for its type. Free, two minutes.
- Pre-approve the assessment so Enbridge pays its share of the audit.
- Get the audit: a measure-by-measure list of gas savings, costs and paybacks.
- Pre-approve each measure under Prescriptive or Custom Retrofit before any purchase order.
- Install, then submit invoices and proof of installation; Enbridge pays after approval.
- Stack the rest: Save on Energy for electricity measures and, in Toronto, City Energy Retrofit Loans for the remaining cost.
Where owners lose the incentive
Buying first
The equipment is ordered before approval, so the incentive is gone. This is the most common and most expensive mistake.
Emergency replacement
A boiler fails in January and gets replaced like-for-like the same week. No time for approval, and no upgrade.
No savings estimate
Custom Retrofit pays on gas saved. Without an engineering estimate or audit, the application stalls.
Missed deadlines
Each program has yearly cut-offs. The 2026 prescriptive window closes December 31, 2026.
How we help
We benchmark the building, run the assessment Enbridge co-funds, estimate the gas savings, and prepare every pre-approval before you commit to anything. Then we stack Enbridge with Save on Energy and city financing so the incentives cover as much of the cost as the rules allow. See all incentives or start with the free benchmark.

Quick answers
Does Enbridge pay for energy audits of commercial buildings?
Yes. Under 2026 terms, Enbridge Gas pays up to 50% of eligible assessment costs, to $6,000, $10,000 or $20,000 depending on the building's annual gas use. The assessment must be pre-approved.
What is the Enbridge Custom Retrofit incentive?
Up to $0.40 per cubic metre of natural gas saved, up to 75% of the extra cost of the efficient option, to $100,000 per project ($500,000 for institutional customers). Projects must be pre-approved.
What equipment gets a fixed rebate?
The Prescriptive Incentive Program pays set amounts per unit, for example up to $18,000 for a hybrid rooftop unit, $14,000 for a condensing make-up air unit and $8,000 for an energy recovery ventilator. 2026 applications close December 31, 2026.
Can I apply after the equipment is installed?
Usually not. Most Enbridge commercial incentives require approval before the equipment is purchased. Talk to us before you sign a quote.
