Double glazed windows are very energy efficient, helping reduce heat loss or heat gain by almost 30 per cent in comparison to single glazed windows.

The Victorian Government is committed to helping households and businesses reduce their bills by offering financial incentives for glazing through the Victorian Energy Upgrades program.

All Victorian households that want to seal their household are eligible to participate. For more information about glazing, see Sustainability Victoria.

What discounts are available?

  • Replacing single glazed windows with double glazed windows
  • Installing a product to existing windows to improve thermal efficiency

How to get involved

To receive an incentive for installing glazing, you must use an accredited provider to complete the upgrade or facilitate it. Contact an accredited provider to find out more information on how to participate.

Please note, accredited providers can operate freely like any other business and therefore choose what upgrades they deliver. As a result, some accredited providers may not currently be undertaking this activity or may only be operating in certain locations. We recommend you contact the accredited providers listed to find out more. Some keep waiting lists for activities and may contact you if circumstances change.

The administrator of the program, the Essential Services Commission, has approved every registered product under the program to meet minimum efficiency, quality and safety benchmarks.
