What Home Renovation Savings pays for insulation in Niagara Falls
We re-read the program's pages and both eligibility documents on October 3, 2026. There are two ways in: an attic-only stream with no assessment, and the assessment stream, where insulation, windows, air sealing and a heat pump water heater are bundled.
Attic, no assessment
The attic stream pays half of the after-tax cost, up to $1,250 for an attic from R-12 or less to R-50, $1,000 from R-25 or less and $800 from R-35 or less. A participating insulation contractor must do the work.
Attic, with assessment
In the assessment stream an attic brought to at least R-50 pays $1,500, $1,200 or $900 by starting R-value, pro-rated by the share of the roof you insulate (minimum 50%).
Cathedral ceiling or flat roof
$750 in the attic stream and $780 in the assessment stream. Any combination of attic, cathedral and flat roof counts as one measure, capped at $1,500 in the assessment stream.
Exterior walls
$1,200 for R-7.5 to R-12 added, $2,100 for more than R-12 to R-20 and $3,600 for more than R-20. Minimum 20% of wall area, pro-rated.
Basement walls, slab and headers
Walls up to $1,500, a slab $500 and a header $300. Wall plus slab is capped at $2,000, and all three at $2,300.
Crawl space and exposed floors
Crawl space walls $600 or $1,200, ceiling $1,200, header $300, combined up to $2,700. An exposed floor over a garage earns $300 at R-20 or more.
Semis and row homes
Semi-detached and end-unit row homes get 75% of the walls and basement maximums. Middle-unit rows get 50%.
Audit rebate and cap
The assessment stream returns $600 for the audits and caps insulation rebates at $7,700, inside an overall $10,000 limit, or $5,000 for Enbridge gas homes.
Attic stream work must be finished by November 30, 2026 and entered in the system by December 31. In the assessment stream, the post-audit must be scheduled by November 30 and completed by December 31, 2026, or within 180 days of your first assessment.
A large eligible pool
The 2021 Census counts 13,845 owner-occupied detached houses built before 1981 in Niagara Falls. 66% live in detached houses and 70% own. 5.4% report needing major repairs. Only 4% live in tall apartments. For a city of this size, many homeowners can be considered.
NPEI and the rebate
Niagara Falls is served by Niagara Peninsula Energy (NPEI), not Alectra as some pages said. NPEI does not run the insulation rebates. Heating fuel sets the cap: $10,000 for electricity, oil, propane or wood and $5,000 for Enbridge gas.
Moderate winters, still worth it
The January average low is -6.1°C and the record low from 2015 to 2024 was -22.6°C. Insulation reduces heating and cooling loads in summer too. Ask the advisor to show expected savings by surface so you can order the work.
Second rounds
A household that finishes the assessment stream can apply again with new assessments, but there is no second $600 audit rebate, and the total across rounds is capped. Keep a record of what the first round paid.
How to claim in Niagara Falls
- Confirm the house is an eligible type and find the attic's R-value.
- Choose a stream: pre-register for the attic stream, or book a home energy assessment for the full bundle.
- Get quotes that state the R-value you start with, the R-value you reach and the share of each surface you will insulate.
- Do not start any work until the in-home visit or first assessment has happened.
- Keep invoices and your property tax bill for the paperwork, and finish before the November 30 and December 31, 2026 dates.
