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?
For the Canada Greener Homes Grant side of the HER+ Program:
- The home is a low-rise residential dwelling such as; a detached home, semi-detached, row house, or mobile home on a permanent foundation (can be on leased land)
- You are the residential property owner (proof of ownership by property tax bill, deed to the home, or land lease transfer papers must be provided)

- 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
- 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?
- The Canada Greener Homes Loan program sets a tentative one-year work period to complete your home retrofits and have a post-retrofit assessment
- The one-year time limit is based on the date of loan acceptance
- To discuss this one-year time limit, or to inquire about work period extensions, contact the Canada Greener Homes Loan Program representatives by phone at 1-866-292-9517 or by email at [email protected]

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
