Weather sealing & insulation

Did you know that many Victorian homes are poorly insulated and have high air-leakage rates, causing hot or cool air to escape unnecessarily?

These draughts make the temperature of your home more difficult to regulate, promote an unhealthy living environment, and require extra energy use for heating or cooling.

The Victorian Government is committed to helping households and businesses reduce their bills by offering financial incentives for weather sealing and insulation upgrades. By participating, you can save money on the initial upgrade costs, reduce your energy bill and help the environment.

Am I eligible to participate?

Double-glazing windows

All Victorian households and businesses are eligible to participate.This may be for installing new windows or adding panes to your existing windows.

Weather sealing

All Victorian households are eligible to participate. This could include:

  • weather sealing for doors or windows
  • sealing wall vents
  • installing a wall exhaust fan, or modifying an existing wall exhaust fan, that can be closed when not in use
  • sealing chimneys to shut out draughts when you're not using the fireplace.


Incentives are not currently available for ceiling and under-floor insulation. The Department of Environment, Land, Water and Planning is assessing options with a view to re-introducing incentives in the future. For more information, please contact
