How much you get
Pairs naturally with other upgrades
London earned its nickname the Forest City for its tree canopy, and its housing stock ranges from Victorian-era homes near downtown and Old North to postwar suburbs further out, which means the condition of an existing tank varies as widely as the age of the house itself.
What's actually different about London
Western University's presence means a significant chunk of London's older core housing, especially near the university and downtown, is rental property, similar to the pattern you see in other Ontario university towns like Guelph and Kingston.
London's Climate Emergency Action Plan sets targets for cutting building-sector emissions and specifically names retrofitting the city's older housing stock as one of its harder but necessary goals.
Tankless and heat pump water heaters, compared
For London's older Old North and downtown-area homes, a tank is a common candidate for replacement well before the newer suburban stock further out needs one, which is where a tankless unit's 15-plus year lifespan and roughly 97 percent efficiency (versus about 67 percent for a standard tank) pays off fastest. A heat pump water heater is the other high-efficiency route, with a coefficient of performance around 2.5 to 3.5, and it's what the $500 provincial rebate specifically supports.
How to claim it
In London, it's worth telling your assessor whether you're in one of the older Old North or downtown-area homes, since those tend to have tanks further past end-of-life than newer suburban stock.
- Book an initial home energy assessment ($600, refunded later)

Common questions
What rebates cover water heaters in London?
Ontario's program rebates heat pump water heaters under the same Home Renovation Savings framework as heat pumps. Confirm the current amount with your installer, since these figures change more often than the headline heat pump numbers.
Do older Old North homes in London qualify the same as newer suburban ones?
Yes, eligibility doesn't change by neighbourhood or home age. What does change is how likely an older home's existing tank is to already be near or past end-of-life, which tends to be more common in London's older core.
Are tankless water heaters rebated in London?
Standard tankless (on-demand) gas water heaters generally aren't rebated. The $500 provincial program is built around heat pump water heaters specifically, though tankless is still worth considering for the efficiency and lifespan gains on its own.
Your utility: London Hydro
London Hydro bills electricity across the city and has remained an independent municipal utility rather than merging into a larger regional player. The $500 water heater rebate is a provincial program rather than a London Hydro incentive, but the utility is your contact for capacity questions and worth checking for its own conservation offers.
