What is Home Energy Retrofit Rebate Calculator
Estimate Home Energy Retrofit Rebate in Seconds
Upgrading your home with energy-efficient changes can lower utility bills, improve indoor comfort, and reduce your environmental impact. Many federal, provincial, and territorial programs are active across Canada. They offer rebates and grants to help homeowners offset the cost of eligible energy retrofits. Our Home Energy Retrofit Grants Calculator helps you determine the financial rebate to offset upgrade costs you may receive. It calculates the grant amount based on your planned improvement work and property details.
Whether you're adding insulation, replacing windows, installing a heat pump, improving air sealing, or investing in solar panels, this home energy retrofit calculator provides a quick estimate of your potential rebate for costs due to improvements. Instead of searching through multiple rebate programs and grants, you can enter a few details and receive an instant estimate of the available financial support. It is a free online tool that estimates the rebate or grant you may qualify for when completing eligible home energy improvements.

Why We Created This Home Retrofit Support Calculator
Many homeowners know they can receive rebates for energy-efficient upgrades or improvements, but calculating how much rebate they can get can be confusing. There are numerous rebate programs offered by federal, provincial, municipal, and utility providers, each with different eligibility requirements and incentive amounts. We created this calculator to simplify the process. This calculator helps homeowners:
- Estimate eligible retrofit rebates before beginning upgrade work.
- Compare different home upgrade/improvement projects.
- Understand which upgrades may give rebates.
- Plan renovation budgets more effectively.
- Maximize available government and utility rebates.
- Make informed decisions about energy-efficient home improvements.
Rather than reviewing multiple rebate guides, you can receive an estimate in just a few clicks.

Step 2: Choose Your Location
Indicate whether your home is located in a northern or off-grid community by selecting Yes or No.
Step 3: Select Planned Upgrades
Check the energy-saving upgrades you want to make, such as insulation, air sealing, windows and doors, a smart thermostat, a heat pump, renewable energy systems, or home resiliency improvements. You can select more than one upgrade.
Step 4: Calculate Your Rebate
Click the Calculate Rebate button to see an estimate of the rebate you may qualify for based on your property details and the retrofit projects you selected.
Eligible Home Energy Retrofit Categories
The calculator supports many of the most common energy efficiency improvements.
Home Insulation
Adding insulation helps reduce heat loss during winter and keeps your home cooler during summer. Eligible insulation projects may include:
- Attic insulation
- Roof insulation
- Exterior wall insulation
- Basement insulation
- Crawlspace insulation
- Floor insulation
Improved insulation can significantly reduce heating and cooling costs while increasing indoor comfort.
Air Sealing
Air leaks around windows, doors, attics, and foundations allow heated or cooled air to escape. Air sealing improvements may include:
- Caulking
- Weatherstripping
- Sealing attic penetrations
- Improving building envelope performance
Reducing air leakage improves energy efficiency and helps maintain consistent indoor temperatures.
Windows and Doors
Replacing older windows and exterior doors with energy-efficient models can improve insulation and reduce heating and cooling costs. Many rebate programs encourage the installation of high-performance windows and certified exterior doors.
Smart Thermostat
Installing a smart thermostat allows homeowners to better control heating and cooling schedules. Smart Thermostat retrofit renate benefits include:
- Lower energy consumption
- Improved comfort
- Automated temperature adjustments
- Remote control through mobile apps
Space and Water Heating (Heat Pumps)
A heat pump is the most popular energy-efficient home heating system. Eligible systems may include air-source, cold-climate, and ground-source heat pumps. Replacing older heating equipment with efficient heat pumps can significantly reduce household energy use.
Renewable Energy (Solar PV)
Installing rooftop solar panels helps homeowners generate renewable electricity and reduce long-term utility costs. Some rebate and grant programs provide financial assistance for eligible solar photovoltaic systems.
Resiliency Measures
Certain programs also support improvements that increase a home's resilience to climate-related risks. Examples may include:
- Flood protection improvements
- Fire resilience upgrades
- Weather-resistant building improvements
These projects help protect homes while improving long-term sustainability.
