Read this first. We cannot tell you that you will receive this money, and we do not treat it as a discount you can subtract from a quote. Focus on Energy states that receipt of an application does not guarantee payment [W2]. Rebates run while funds last [W2]. Confirm current terms with Focus on Energy directly, on 800.762.7077, before you purchase anything.

The amounts

Three income tiers, based on area median income (AMI) [W2]:

Household incomePer windowCap per home
Standard income, above 150% AMI$200$3,000
Moderate income, 80% to 150% AMI$400$5,000
Low income, below 80% AMI$600Up to total material cost

The rebate covers materials only, not labour, and cannot exceed the purchase price of the windows [W2].

The rule that catches people out

The rebate reservation must be approved before you purchase and before installation, and it is the Trade Ally contractor who submits it [W2]. This is not a rebate you apply for afterwards with a receipt. If you buy windows first, the reservation route is closed.

The dates

  • Purchase and installation must happen between June 1, 2026 and December 15, 2026, while funds last [W2].
  • Applications must be postmarked by December 15, 2026, and within 60 days of installation [W2].
  • Processing takes about 8 to 10 weeks [W2].

If you are starting now. This page is dated November 13, 2026. That leaves roughly a month inside the current window, and the sequence required is: find a participating Trade Ally, have them submit a reservation, wait for it to be approved, then purchase, then install, all by December 15, 2026. Ask any contractor you speak to, plainly and early, whether that is still achievable on their schedule. Many will say it is not, and that is useful to know before you plan a budget around it.

2027 terms. As of November 13, 2026, Focus on Energy had not published terms for 2027. We do not know whether the programme will continue, at what amounts, or with what dates. Do not assume a 2027 rebate exists.

Who is eligible

From the programme terms [W2]:

  • An existing single-family home, or a dwelling of three or fewer units. Conditioned space only.
  • At least 51% of the home's heating must come from a participating electric or natural gas utility. Homes heated with wood, oil or LP are not eligible.
  • You must use a participating Trade Ally contractor.

What the windows have to be

You must be replacing existing single-pane or clear double-pane windows, meaning double-pane with no low-E coating, and the new units must be ENERGY STAR Version 7 Northern Climate Certified models [W2].

We do not publish the U-factor and SHGC thresholds behind that certification, because we have not verified them against the EPA specification at source. Ask your contractor for the NFRC label figures on the exact unit and check them against energystar.gov yourself. We explain what the two figures mean on our energy-efficient windows page.

The paperwork

  • An itemized invoice carrying the CPD number [W2].
  • Photos of at least 5% of the windows showing the NFRC sticker [W2]. The stickers come off during installation, so photograph them before they do, or make sure the crew does.
  • Application postmarked by December 15, 2026 and within 60 days of installation [W2].
  • Expect about 8 to 10 weeks of processing [W2].

Questions to put to a contractor

  1. Are you a participating Focus on Energy Trade Ally?
  2. Will you submit the rebate reservation, and when?
  3. Given today's date, can a reservation be approved and the installation completed by December 15, 2026?
  4. What happens to my price if the reservation is not approved, or funds run out?
  5. Are the exact units you are quoting ENERGY STAR Version 7 Northern Climate Certified, and can I see the NFRC label?
  6. Will your invoice be itemized and carry the CPD number?
  7. Who photographs the NFRC stickers?

How to confirm

Go to the source. Focus on Energy's windows page is at focusonenergy.com/windows and the programme phone number is 800.762.7077 [W2]. We re-check that page before launch and again in January, but a page can change the day after we read it. If what you are told differs from this page, Focus on Energy is right and we are out of date.
