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.
