How Durham Greener Homes works
OpenDurham Greener Homes is Durham Region's home retrofit hub. In May 2026 the Region launched a low-interest local improvement charge loan of up to $125,000 at 2%, repaid on the property tax bill over a fixed 15-year term. The loan stays with the property if you sell. At least 80% of the loan must go to energy-efficiency work such as insulation, windows and doors, air sealing, heat pumps, electric or heat pump water heaters, solar panels and batteries; up to 20% can go to other eligible items such as flood protection, electrical upgrades, EV chargers and EnerGuide evaluation costs. Properties in the City of Pickering are not eligible for the loan yet.
