Red flags from contractors

⚠"We can start tomorrow, just sign here"
⚠"Don't worry about pre-approval, we'll figure it out"
⚠"Pre-approval is a formality"
⚠"We'll backdate the paperwork"
⚠"I have a friend at the program who will fix it"

Any of these signals are reasons to walk away. A reputable HRS-participating contractor will insist on pre-approval — it protects them too.

Common questions

What is heat pump rebate pre-approval?

Pre-approval is written confirmation from the Home Renovation Savings Program (HRS) that your planned heat pump installation qualifies for a rebate. You must receive this BEFORE installation begins. Your contractor submits the application; you receive a confirmation letter or email.

How long does pre-approval take?

Typically 5-15 business days from submission. Allow 3 weeks to be safe. Do not schedule installation until you have written pre-approval in hand. If your contractor pushes you to start sooner, that is a red flag.

What happens if I install before pre-approval?

Automatic rejection of the rebate application. There is no appeal process. Even if every other requirement is met perfectly, work started before pre-approval voids your rebate. This is the single most common rejection reason in Ontario.
