The London Environmental Network is a local environmental charity working to increase residential sustainability within our community through our Greener Homes London & Home Energy Assessment programs.

EnerGuide Audits also known as home energy assessments are intended to help you understand how your home uses energy now, and identify retrofits to help improve energy efficiency. The evaluation is carried out by an energy advisor registered with Natural Resources Canada ("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. Home energy assessments model the energy & carbon use of your home, rather than the participants in it.

The London Environmental Network and our energy advisors are registered and certified with Natural Resources Canada. We can provide home energy assessments and assistance in navigating grant, loan and incentive programs.

Including the Home Efficiency Rebate+ ("HER+") program through NRCan and Enbridge, The CMHC & NRCan Interest-free loan up to $40,000 with a 10-year payback period, and the Clean Home Heating Initiative (open to the City of London residents only) and any additional incentives brought forward by the homeowner.

Pre and post-retrofit energy audits are required to qualify for up to $10,000 of reimbursement for eligible retrofits and renovations with an additional up to $600 coverage for audit costs reimbursed upon completion of the HER+ program. One qualifying recommended renovation or retrofit must be implemented to qualify for the audit reimbursement ($600).


Need a post-retrofit audit? We can help! Email [email protected] with your current status, service organization, and any financial incentive participation and we will advise the next steps. 

Please email [email protected] for further details if you wish to have your home energy assessment completed by the London Environmental Network, but are outside our current service area, or if you have any additional questions you wish to have answered prior to scheduling your pre- or post-retrofit assessment. 

EnerGuide audits are required to access the federal Greener Homes incentives, the CMHC no-interest loans for sustainable retrofits, and Enbridge Gas' Home Efficiency Rebate Plus. For Enbridge HER+ participants or the CMHC loan, the next step includes booking your pre-retrofit energy audit. For HER+ participation, please complete the eligibility quiz located on their website prior to booking your audit. One to two weeks prior to your scheduled audit, a member of our service team will set up a call with you to ensure you and your home are ready for a home energy assessment. Additionally, we will discuss any grant, loan, or incentive program interest to ensure eligibility & the processes of entering the program(s). 

Please note, that properties more than 39 km from London's City Centre Towers are subject to a $50 travel fee. Additionally, properties more than 71km from London's City Centre Towers are subject to a $75 travel fee. These fees go directly to your advisor to better support them for their time when travelling to rural areas. Please use a digital maps application to check the distance from your property to the City Centre Towers, and add the fee on check-out if it is applicable. Travel rates are based on the average distance between London City Centre Towers & your home address, rounded to the nearest whole kilometre. We currently do not offer assessments for properties located more than 100km from London City Centre Towers. 

Greener Homes London works to provide residents with the guidance, tools and resources to assist them with reducing their environmental impact at home. With a focus on highlighting the advantages of green modifications, and the benefits of retrofit projects including significantly reducing energy consumption, and often natural gas or propane consumption as well. This, in turn, lowers utility costs and provides a more comfortable home environment. We do our best to keep up to date on available rebates and incentive programs that provide financial assistance for implementing green modifications, our ultimate goal is to create more sustainable homes in London & beyond, and to assist the community in the transition to clean energy.
