What a insulation costs in Victoria
Price depends on which areas you insulate (attic, walls, basement) and how much air sealing is needed. Ask each company for a price per area and the R-value you end up with, so quotes are easy to compare.
That could cut your cost by up to $5,500 if you qualify. Most rebates have rules (income, your current heating, a registered contractor, approval before work starts).
Rebates: our verified program data, checked monthly. Always confirm the exact amount for your home.
Talk to a registered energy advisor first. Some rebates need an evaluation or heat load calculation before any work starts. See the top-rated registered energy advisors in Victoria. Read when to call an energy advisor.

Why insulation matters in Victoria
In Victoria, the average January low is 3°C, colder than 20% of the 123 cities we track. Winters here are mild, so comfort and summer heat matter as much as heating bills. Air sealing and attic insulation still help most, and they also keep upstairs rooms cooler in summer.
Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.

- Ask for the R-value before and after for each area, and the material and depth they will install.
- Ask whether your rebate needs an energy assessment before and after the work, and who books it.
