How much you get
No flat per-window rebate exists on its own in Halifax. Efficiency Nova Scotia doesn't run a standalone windows-and-doors program — instead, ENERGY STAR certified window and door replacements are funded as part of the whole-home Home Energy Assessment (HEA) pathway, up to $5,000 for the standard rebate or up to $15,000 for qualifying moderate-income households under the Moderate Income Rebate. Windows and doors are typically paid out per "rough opening" — if a large bay window fits into one structural opening, it counts as one eligible unit for the rebate, not one per pane.

What you'll actually save each month
Old, drafty windows and doors are a common source of heat loss in Halifax's older housing stock, but the honest math is that windows alone rarely have as fast a payback as insulation or a heat pump — the upfront cost per window is high relative to the heat loss any single window causes. They matter most as part of a whole-home plan.
- Nova Scotia Power electricity (2026): the current residential Energy Rate is 19.128¢/kWh (effective May 1, 2026), plus a $20.08/month base charge. (Check current Nova Scotia Power rates →)
If your home's heat loss is mostly coming from air leaks around old window and door frames rather than the glass itself, air sealing may deliver a faster payback than full window replacement — your Home Energy Assessment will tell you which upgrades your specific home needs most, ranked by cost-effectiveness.

Common questions
Is there a standalone windows and doors rebate in Halifax?
No flat per-window rebate exists on its own. Efficiency Nova Scotia funds ENERGY STAR certified window and door replacements as part of its whole-home Home Energy Assessment (HEA) pathway, up to $5,000 standard or up to $15,000 for qualifying moderate-income households. A large window that fits into one structural opening (a "rough opening") typically counts as one eligible unit.
Do window and door replacements need a home energy assessment first in Halifax?
Yes. Efficiency Nova Scotia requires a Home Energy Assessment before work begins, and the home must generally be at least six months old with no renovations already underway. Work started before the assessment does not qualify for a rebate.
