Rebates
Cities, regions and utilities across Waterloo Region, Guelph, Wellington, Oxford, Halton and Brant pay part of the cost of some plumbing and water work. Here is what is available, who qualifies, and the rules, with a link to each official program page.
New Dundee, Wilmot Township, Kitchener, Waterloo, Cambridge, Guelph, Milton, Halton Hills, Acton, Rockwood and Georgetown
Water heaters and heating
Two programs cover water heaters right now. Most standard tank replacements do not qualify for a rebate.
City of Kitchener homes with a Kitchener Utilities gas account
$500 on-bill credit
Replaces a gas water heater rated under 0.86 UEF with an ENERGY STAR condensing gas model rated 0.86 UEF or higher. Not for new homes or electric-to-gas switches. Send the paid installer invoice and the efficiency rating.
Ontario
$500
ENERGY STAR heat pump water heater. Only as part of a bundle: a home energy assessment plus two or more upgrades.
Ontario
Up to $7,500 (cold-climate air source) or up to $12,000 (ground source)
No assessment needed. The unit must be on Natural Resources Canada’s qualified list. Amount depends on size.
There is no boiler rebate in these programs right now. Checked October 31, 2026 on each program’s official page.
Water softeners
Both of these reward a more efficient softener. They do not pay toward a softener in a house that has never had one.
Region of Waterloo homes on municipal water
$50, one time
Re-plumb your softener so it softens hot water only. Apply on the Region’s rebate form.
Fergus, Elora and Centre Wellington homes on municipal water and sewer
$250 (time-based to demand-based NSF/ANSI 44 softener) or $500 (salt-free NAC/TAC unit)
Apply first: the Township confirms you qualify before you replace anything. Keep the old unit until any inspection is done. One per address, 75 rebates in total, first come, first served. Effective July 27, 2026.

Questions we get asked
In Kitchener, yes: Kitchener Utilities gives a $500 on-bill credit for replacing a gas water heater with an ENERGY STAR condensing model (0.86 UEF or higher). Across Ontario, Home Renovation Savings gives $500 for a heat pump water heater as part of a bundle with an energy assessment. A standard tank-for-tank swap does not qualify for either.
In Waterloo Region, $50 to re-plumb your softener to soften hot water only. In Centre Wellington, $250 or $500 when you replace an older softener with a more efficient one, and you must apply first.
In Halton Region, yes: up to $1,600 for a backwater valve and up to $6,500 for weeping tile disconnection with a sump pump. The County of Brant also has a program. We did not find one for Kitchener, Waterloo or Cambridge.
For some programs, yes: Centre Wellington softeners, Guelph lead pipes and well decommissioning, and Brantford sewer laterals all need approval first. Halton’s flood programs are claimed after the work, within one year, with a permit and final inspection.
We give you an itemized, paid invoice with the model and efficiency details, and we pull the permit when the work needs one. You submit the claim to the program.
No. Programs can change, run out of funding or close. Check the official page linked above before you buy, or ask us and we will check with you.
