Home Energy Assessment Ontario: Cost, Process, and 2026 Rebates

Do you need an assessment for your upgrade?

Start with the measure, not with an audit booking. The current Home Renovation Savings program has two different routes.[1]

Assessment stream: complete two or more upgrades

This route begins with a home energy assessment and can include insulation, windows and doors, a heat pump water heater, and air sealing. The initial assessment must happen before work starts. You then complete at least two qualifying upgrades and return to the same registered energy advisor for the follow-up assessment.[2]

No-assessment paths: complete one or more eligible upgrades

The current no-assessment routes include heat pumps, solar panels with battery storage, standalone attic insulation, smart thermostats, and appliances. This corrects a common source of confusion: a heat pump or solar project does not enter the HRS assessment stream simply because it is a large project.[1]

Program terms still control eligibility, product requirements, and timing. Use our Home Renovation Savings program guide for the current upgrade amounts and application routes.

What happens during an EnerGuide evaluation?

The registered energy advisor assesses the home from basement to attic. Natural Resources Canada says the data collection includes:[3]

• airtightness measured with a blower door test;
• insulation levels in walls, ceilings, and the basement;
• the number, type, and location of windows and exterior doors;
• the size and efficiency ratings of space-heating, cooling, and water-heating equipment; and
• information about ventilation equipment.

This is an energy-performance evaluation, not a substitute for a pre-purchase home inspection, a combustion-safety service call, or a contractor's equipment-sizing calculation. For a closer look at the airtightness test itself, see our Ontario blower door test guide.

Cost and the $600 HRS assessment rebate

NRCan says the combined cost of a pre-retrofit and post-retrofit evaluation may average $600 to $1,000 across Canada. The actual cost varies with the provider and province or territory. Ask the registered service organization what each visit costs and what is included before you book.[5]

Under the HRS assessment stream, the program provides a $600 rebate to offset the initial and follow-up assessments after successful completion. It is one program rebate toward the two visits, not $600 for each visit and not an automatic payment for an assessment-only booking.[2]

After the follow-up assessment and the advisor's document submission, the program says the rebate cheque should arrive by mail within 60 days.[2]

What you receive after the evaluation

NRCan says the homeowner receives an EnerGuide rating and label, a Homeowner Information Sheet, and a Renovation Upgrade Report.[4]

The current EnerGuide rating estimates the home's annual net energy use in gigajoules. Lower is better. The model uses standard operating conditions so homes can be compared, but it should not be expected to match your utility bills. Occupant behaviour, weather, and energy loads such as a pool or hot tub can change actual use.[4]

How to book the right advisor

1. Confirm that your planned measures belong in the HRS assessment stream before booking.
2. Use NRCan's directory of registered service organizations for existing homes.[5]
3. Ask the organization for a written price for the initial and follow-up visits and confirm it delivers the HRS assessment stream in your area.
4. Complete the initial assessment before beginning any assessment-stream work.
5. Keep the reports, invoices, and program documents, then book the follow-up with the same registered energy advisor after at least two qualifying upgrades are complete.

Registered service organizations and energy advisors are independent businesses, not NRCan agents, partners, or employees. NRCan also warns that it and its EnerGuide and ENERGY STAR brands do not solicit homeowners by telephone, email, or door-to-door for inspections or sales.[5]

Prepare safely for the blower door test

Follow the preparation instructions from the service organization. NRCan says not to use fuel-fired space heating or water heating, wood-fired appliances, or other solid-fuel appliances during the evaluation because the blower door test could affect safe operation. The advisor returns the equipment to normal settings after the test.[3]
