Choosing rebate-eligible windows and doors

January 29, 2020


Updated April 6, 2022

I bought a much unloved house in need of some TLC. My home inspector thought I was crazy. “You’re a brave lady,” he said. I wasn’t brave, I just wanted a house and this was the best I could afford. Luckily, I was pretty handy.

Going deep into home renos

At least the wiring was adequate, the roof was OK and the structure was sound, but the house required, what they call in the energy-efficiency industry, a “deep retrofit.” Because the furnace and leaky water heater were on their last legs, I had to upgrade those first. Then, little by little, I worked on the envelope of the house. This means the exterior walls and attic insulation, siding, windows and roof.

Think your windows are bad?

If there was an award for the worst windows, I’d have won. My little pre-war, unloved fixer had a motley mix of them from a variety of decades (none from this century). Whenever the dogs barked at the mailman, the thin single pane of my living room window would shimmy and shake. And at night? A light breeze would make the aluminum frame of my bedroom window rattle, jolting me and the pups from a deep sleep. And frankly, they were ugly. They made my house look like a dilapidated squatter house. Don’t believe me? Have a look.

Rebates help, but not the only reason to upgrade

All of FortisBC's rebates are designed to help you offset the extra cost between a standard item and an energy-efficient one. But let’s be honest. You want to upgrade your windows and/or doors for more reasons than energy efficiency. I mean, who shows off their new blown-in attic insulation to the neighbours? My new windows? Folks who knew what my house looked like before—the eyesore on the street with undesirable tenants—would walk by and ogle them enviously. New windows have the same effect on your neighbours as a kitchen renovation, without having to invite them into your home to see them.

But as well as adding an incredible aesthetic appeal to both the interior and exterior of my house, the comfort was amazing. Even though I hadn’t insulated yet, my home felt more solid and sound. The rattling was gone, the cold drafts stayed outside and my home was incredibly quiet. My neighbour’s grunge band and the all night trains rumbling in the distance were now just audible memories with my high-end double-pane windows.

Maximize your investment

Windows are a HUGE investment. Possibly even more than a kitchen or bathroom renovation, depending on the number and size of the windows you’re replacing. You’re going to spend a lot, and regardless of the energy efficiency of the window itself, you still have to pay for labour. So I recommend you buy the most efficient ones possible. The investment will pay off year-after-year. I mean can you argue with these?

Be clear on window (and door) rebates

Before you buy the first window you see, remember, not all windows and doors qualify for rebates. So how do you know which ones do? Well, FortisBC has some tips to help you know what you’re talking about when getting quotes from window companies.

Demystifying window and door terminology

Here’s an explanation of some of the technical terms to help ensure the products you buy are rebate-eligible.

U-Factor: also known as U-Value, U-Factor measures a window or door’s resistance to heat flow. The lower the number, the better its insulating properties. U-Factor can be expressed in metric or imperial units.

Metric vs. imperial: U-Factor requirements for rebates are listed in metric units (W/m2-K). To convert imperial U-Factors to metric U-Factors, multiply the number by 5.678.

Tier 1 and Tier 2: to help you choose the most efficient windows and doors, its broken down into tiers. Tier 1 windows have U-Factors between 1.40 and 1.23 (W/m2-K). Tier 2 windows/doors have the lowest U-Factor (1.22 W/m2-K or lower) and are the most efficient, so the rebate is higher. Please note: FortisBC doesn't offer rebates on Tier 1 doors. And if you live in the city of Vancouver, be aware that Tier 1 windows are not eligible for rebates, and Tier 2 doors and windows must have an invoice dated between October 1, 2021 and March 31, 2022 to be eligible for rebates.

Rebates are great. But what’s the catch?

People often ask me why FortisBC offers rebates to help customers use less energy. It’s all part of a bigger plan I tell them; one that will help our province move towards a lower carbon future. To support this, FortisBC created 30BY30, a target that aspires to reduce their customers greenhouse gas emissions by 30 per cent* by the year 2030.


You could be eligible for a combined rebate of up to $3,000 by installing a combination of Tier 1 and Tier 2 windows and Tier 2 doors. Additional requirements to be eligible for these rebates are listed here.

Now you’re ready to apply for your rebate

Once you’ve selected your rebate-eligible windows and/or doors and had them installed by a licensed contractor, it’s time to apply online for your rebate (you have up to six months from your invoice date to apply). As well as the detailed invoice from the window manufacturer/installer, you’ll also need to include a photo of at least one manufacturer’s label from a window and/or door. Here are some samples:
