Welcome to the frequently asked question page for home energy assessments with the London Environmental Network. From what is included in a home energy assessment, to what financial incentives are associated, this web page has tons of information to help. This is a dynamic web page, so feel free to search (command/ control + F) if you are looking for any specific questions.
What is a home energy assessment?
- Also known as an EnerGuide Audit, a home energy assessment is intended to help you understand how your home uses energy now, and identify retrofits to best improve its energy efficiency
- The evaluation is carried out by an energy advisor registered with Natural Resources Canada (NRCan), through a service organization registered with NRCan
- The energy advisor will assess your entire home from the basement to the attic
- Using professional analysis equipment, the advisor will recommend the best approaches to improve the overall efficiency of your home
- After the evaluation is completed, the advisor will give you an EnerGuide rating for your home and a personalized energy efficiency report, known as a renovation upgrade report, to help you make decisions about possible upgrades
- Rather than occupant(s) behaviour, the evaluation considers the performance of the home itself
Is my home eligible for a home energy assessment?

- Below-grade renovations are usually accepted
- Occasionally, cosmetic renovations are accepted
- Review the Home Energy Assessment eligibility page for more information or contact our office team at [email protected] or by phone at 226-700-6945
Is my home addition eligible for rebates under the HER+ program?
- New additions are not currently eligible for rebates under the HER+ program
- If you are installing an addition after the post-retrofit assessment, talk to a member of our office in regards to the potential impacts to your rebates this may have (pro-rated adjustments based on changes to the existing building footprint)
How do I know my retrofits are eligible for rebates?
- There are no applications for the HER+ program
-
The main piece to be aware of is your rebate maximum (eg. up to $10,00 or up to $5,000), and to ensure you are following installation requirements
- Complete the 'Get Started' quiz for confirmation on your rebate maximums
- General installation requirements can be found on the HER+ terms and conditions page, or the NRCan eligible retrofit and grant amounts list
-
For any physical product, with a make and model- it should be verified by the homeowner ahead of purchase by using the NRCan searchable product list
- This includes windows, doors, air source heat pumps, ground source heat pumps, cold climate heat pumps, and heat pump water heaters
- If the homeowner is using a contractor, group, certified buyer or similar entity, it is strongly recommended to still verify retrofit model eligibility ahead of purchase
How does the $600 assessment grant work?
- Under the HER+ Program, participants can receive up to $600 in grants for the cost of the home energy assessment, separate from their total grant availability (Eg. $10,000 in grants + $600 assessment reimbursement)
- To receive this credit, homeowners must go through the HER+ program successfully
- This means, the homeowner has a pre-retrofit assessment, installs a minimum of one accepted retrofit under the program, and has a post-retrofit assessment
-
The $600 assessment credit is the maximum available
- Homeowners should expect to pay upfront for assessments with the $600 rebate arriving at the same time as their retrofit rebates, upon completion of the program
-
The $600 assessment rebate does not entirely cover the cost of a pre-retrofit and post-retrofit assessment, homeowners should expect to cover the remainder
- NRCan and Enbridge will not pay out more than what was paid for home energy assessments
- The rebate would be pro-rated if homeowners paid less than $600 for a pre-retrofit and post-retrofit assessment
What is reviewed during a home energy assessment?
- The advisor will examine the interior and exterior of the home looking at the overall condition and quality, while looking for any issues or problems to note for improvement
- They will review the condition, effectiveness, and make/model of existing windows, doors, insulation, and mechanical systems (air conditioning, water heater, furnace)
- They will complete a blower door test to evaluate overall air leakage from the home
- The advisor will then model your home in software to evaluate the home as a system
-
The advisor will then summarize these opportunities in a home energy assessment report, known as a renovation upgrade report
- A list of home improvements (retrofits) will be added, where homeowners can have the largest impact on reducing heat loss and carbon usage while improving the energy efficiency of the home
- At the post-retrofit assessment, the advisor will also review the installed retrofits and documentation affiliated with the retrofits
How many upgrades do I have to install?
-
Under the HER+ program, one preliminary qualifying measure is required to complete the program successfully
- This includes window and door upgrades, insulation upgrades, heat pumps, and heat pump water heaters, solar photovoltaic system installation, or solar photovoltaic battery backups
-
The following installations do not qualify if installed without an additional qualifying retrofit
- smart or programmable thermostats, basement and attic waterproofing
-
Basement and attic waterproofing, solar photovoltaic installations, or solar photovoltaic battery backup rebates are available for owner-owned and occupied homes
- Enbridge-only qualifying homes are not eligible for these measures
How can I apply for the HER+ Program or the Canada Greener Homes Grant?
- There are no applications or portals for the HER+ program or the Canada Greener Homes Grant Portal
- The required components for participation are submitted through your advisor and service organization, directly to NRCan and Enbridge
-
Note** The Canada Greener Homes Loan program is a separate program from the Canada Greener Homes Grant program
- The Canada Greener Homes Loan program does require an application from the homeowner, submitted after the pre-retrofit assessment
Can I complete the retrofit work myself?
-
Yes, any non-mechanical retrofits can be completed by the homeowner if desired
- Some examples include insulation upgrades, or window and door replacements
-
Rather than using an invoice, the advisor will document your material costs for the work completed
- You must keep all receipts, and material costs associated with the work for evaluation at the post-retrofit assessment
- Any mechanical retrofits cannot be completed by the homeowner and require a certified contractor/ specialist to complete the work
Are there time limits on the HER+ program?
- The HER+ program is confirmed to run until 2027
- Homeowners should plan to have their post-retrofit assessments in mid-to-late 2026 to ensure the advisor has time to submit them through the program ahead of the 2027 deadline
- There are no time limits for the HER+ program, or on the work period of home energy assessments
What rebates will I get for my retrofits in the HER+ program?
- Rebates are calculated differently based on the type of retrofit you are installing
- To check available rebate maximums review the NRCan eligible retrofit and grant amount list, visit the HER+ program page, or view the LEN HER+ rebate summary sheet
-
For windows and doors; there is a 'more' and 'most' energy-efficient model that can be installed for rebates
- For the 'more' efficient model- rebates are $175 per rough opening ($125 for non-owner-owned/ occupied participants) or $325 for the 'most' efficient model installed per rough opening ($250 for non-owner-owned/ occupied participants)
- Please note, under the HER+ program, rough opening is defined as the framed area around the window
-
For insulation upgrades, it is tiered based on the level (R-value) of insulation existing at the pre-retrofit assessment, to the level of insulation installed pro-rated (multiplied) by the area of the home done
- Please review the LEN rebate summary sheet for details on the rebate amount for insulation
- The less insulation existing at the pre-retrofit assessment = higher rebates
-
For the multiplier, it is based on the area they define (eg. walls, basement, attic) x amount done (eg. 50%)
- If the full area is retrofitted to the required R-value, rebates will not be pro-rated or adjusted
-
For any heat pumps; ground source heat pump, cold climate heat pump, or geothermal systems- there are set rebate amounts based on the make and model installed
- Review the LEN rebate summary sheet, or the NRCan eligible retrofit and rebate amount list for more information on these rebates
- Rebates for home heating and cooling range from $2,500- $6,500 for an installation of an eligible system
- For a heat pump water heater (domestic hot water heat pump), rebates of $ 1,000- $1,3000 are available for the installation of an eligible system
-
For a smart or programmable thermostat installation, $50 - $70 in rebates is available for the installation of an eligible system
- The Enbridge instant smart thermostat rebate (added before purchase) can be combined with the HER+ smart thermostat rebate
-
For air sealing measures, rebates are based on the level or percentage of improvement between the blower door test results at your pre-retrofit versus your post-retrofit assessment
- Rebates are tiered at achieving the base target, achieving 10% above the base target, and achieving 20% above the base target
- Achieving the base target earns a rebate of $725 ($550 for non-owner-owned/ occupied participants)
- Achieving 10% above the base target earns a rebate of $1,050 ($810 for non-owner-owned/ occupied participants)
- Achieving 20% above the base target earns a rebate of $1,300 ($1,000 for non-owner-owned/ occupied participants)
- For solar photovoltaic systems, rebates of $1000 are available per kilowatt (kW DC) installed, up to a $ 5,000 maximum
- For solar photovoltaic battery backups, a maximum of $1000 is available in rebates for the installation of an eligible system
- For roof waterproofing, a rebate of $150 is available for the installation of a self-adhering roofing underlayment applied to the entire roof
-
For basement waterproofing;
- A rebate of $875 is available for foundation water-proofing (a minimum of 80% of below-grade wall area is required)
- A rebate of $600 is available for moisture-proofing of 100% of the crawlspace floor, walls, and headers
Are there time limits on the Canada Greener Homes Loan Program?

What other financial incentive programs can I take part in?
- Please review the Greener Homes London Financial Incentive List for up-to-date information on available rebates, loan programs, grants, or low-income programs currently available
Can I go through the HER+ program more than one time?
- Homeowners can participate in the HER+ program at the same address a maximum of two times, but it is always recommended to maximize your retrofits during the first participation when possible
-
The second time a homeowner goes through the HER+ program the $600 assessment rebate is not available
- This means the homeowner will have to pay for the pre-retrofit and post-retrofit assessment completely out of pocket the second time through
- The energy assessment are still a requirement for the HER+ Program with a second participation
-
Homeowners also only have the remainder of unused rebates available the second time through
- For example, if the homeowner has up to $10,000 available and used $7000 in rebates their first time through the HER+ program, the second time they will have a maximum of $3000 in rebates available
