Quick quiz: how windows and doors work
Ten questions on the technology. Tap an answer to see why.
Short answer: FortisBC pays $100 per window or door, up to $2,000. The new unit must have a U-factor of 1.22 or lower (metric), be certified, and be installed by a licensed contractor. Apply within six months of your invoice.
Kelowna is in the Okanagan, with hot summers and cold, grey inversion winters. Kelowna is FortisBC country for both electricity and gas. That means BC Hydro's rebates and Peak Saver do not apply here. FortisBC runs its own heat pump, insulation and window rebates instead.
The window and door rebate rules
- Amount: $100 for each window or door, up to $2,000 per home.
- Efficiency: U-factor of 1.22 W/m²·K or less. Your quote should list it.
- Certified by CSA, Intertek, Labtest, QAI or NFRC.
- Replacing existing windows or doors between heated and unheated space. Skylights don't count.
- Installed by a licensed contractor. Self-installs don't qualify.
- Apply within six months of the invoice.
Bonuses for doing more than one upgrade
FortisBC adds a $300 bonus when you do windows (worth at least $250 in rebates) plus another eligible upgrade, or a bonus of $750 to $2,000 based on how much your EnerGuide rating improves.
Is replacing windows worth it?
Honestly, windows are one of the most expensive upgrades for the energy they save. If your windows are in decent shape, insulation and air sealing usually save more per dollar. Replace windows when they're failing, fogged or drafty, and use the rebate to take the edge off.
The income-qualified CleanBC Energy Savings Program (July 2026 rules) does not include windows. ECAP may cover some draftproofing for income-qualified homes.
What's different in Kelowna
- FortisBC is the electric utility in Kelowna, so BC Hydro programs (including Peak Saver and BC Hydro's heat pump rebate) are not available. Use FortisBC's matching programs.
What to do next
- Check which utility heats your home.
- Get quotes that list the U-factor and certification of each unit.
- Ask about insulation at the same time to earn the bonus.
- Keep your invoice and photos of the labels, and apply within six months.
