What Home Renovation Savings pays for insulation in Kitchener
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.
Housing and eligibility
The 2021 Census counts 21,465 owner-occupied detached houses built before 1981 in Kitchener. 47% of households live in detached houses, 66% in an eligible house type and 60% own. 4.7% report needing major repairs. 15% live in tall apartment buildings and 15% in smaller ones, which the program excludes.
Coaching for everyone, a loan for some
Retrofit Waterloo Region offers a free Energy Coach to homeowners anywhere in the Region. Its loan, up to $40,000 at 2.5% over 10 or 15 years, is repaid on the GrandBridge Energy bill and is for customers in Cambridge and North Dumfries. Kitchener and Waterloo are served by Enova Power, so the loan does not reach them. The coach can still help you decide between the attic stream and the full assessment.
The two-measure minimum for walls and basements
Insulation measures in the assessment stream count toward the two-measure minimum. A basement wall plus a slab counts as two. A wall plus a header counts as one. An attic is one measure, and attic, cathedral and flat roof together are one. Ask the advisor how each of your planned jobs counts before you book the work.
Semis and rows
Kitchener has 5,530 semi-detached and 12,855 row households. Semis and end rows get 75% of the wall and basement maximums, and middle rows 50%. The attic is not reduced.
How to claim in Kitchener
- Book the free Energy Coach to review the plan before you pay for an assessment.
- 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.
