How much you get
Why this one needs an assessment
Windows and doors bundle into the assessment-required path alongside insulation, water heater, and air sealing. You need at least 2 of those upgrades — completing 3+ earns an extra $500 bonus.
Local programs in London
London Hydro and Enbridge Gas don't run a window-and-door-specific top-up on HRSP. If London's new Community Energy Retrofit loan program ends up including window and door replacement once its terms are finalized, that could stack with the HRSP amount above — the City hasn't published confirmed loan caps yet, so check the City of London climate action page → before counting on it.
How to claim it
- Book an initial home energy assessment with a registered energy advisor ($600, refunded later)
- Get your custom report
- Complete the window/door replacement plus at least one other qualifying upgrade
- Book a follow-up assessment
- Rebate arrives by mail within 60 days

Common questions
Are window and door rebates available in London?
Yes, through the same provincial Home Renovation Savings Program used across Ontario. London Hydro and Enbridge Gas customers follow the same $100-per-rough-opening structure, bundled with insulation or another qualifying upgrade — there's no separate London-only window rebate on top of it right now.
Do all new windows qualify for the rebate in London?
No. They need to meet ENERGY STAR's rating for your climate zone. A standard double-pane replacement usually won't qualify on its own, and London's assessor confirms the rating as part of the required energy assessment.
Your utility: London Hydro
London Hydro has stayed independently city-owned rather than joining one of the regional consolidations that reshaped utilities elsewhere in southwestern Ontario. The province-wide windows and doors rebate pays out the same regardless of who's on your electricity bill, but London Hydro is your point of contact if your installer needs a service upgrade signed off, and it's worth checking whether London Hydro runs any of its own conservation incentives that could stack with your renovation.
What London's winters mean for this upgrade's payback
London sits between Lake Huron and Lake Erie, close enough to both to catch lake-effect snow squalls that can drop several inches in a single afternoon even when the broader forecast looks mild — the 10-year average January daily low (2015-2024) is -7.5°C, with a coldest recorded day of -30.8°C. Southwestern Ontario's snowbelt reputation is real, and it's part of why window and door condition matters more here than the average January temperature alone would suggest.
