Two measures is the number that changes which programme you are in.
The attic on its own goes through the fast stream: no energy assessment, up to $1,250, capped at half the invoice. The moment you do a second measure you can instead go through the assessment pathway, where the attic alone pays up to $1,500, exterior walls pay up to $3,600, and a third measure adds a $500 bonus.
The trade is time and paperwork: an energy advisor has to assess the house before the work and again afterwards. For an attic-only job that is not worth it. For an attic plus walls it usually is, by a wide margin.
| Scenario | Pathway | Rebate |
|---|---|---|
| Attic only | Attic stream, no assessment | up to $1,250 |
| Attic + walls | Assessment stream | up to $5,100 |
| Attic + walls + air sealing | Assessment stream, third-measure bonus | up to $5,850 |
Amounts are set by Enbridge Gas and Save on Energy and are quoted from the programme pages — attic stream, assessment stream — checked September 2026.
If your walls are already insulated, or the house is post-2000, the second measure is not there and the fast stream is the better route. We check the walls before recommending the slower pathway, because sending you down it for nothing costs you weeks.
You can, or we can point you at one. The advisor must be independent of the installer, which is exactly as it should be.
Typically a few weeks end to end, because of the two assessment appointments either side of the work.
