Water heating can account for 16% of your energy bill. It's possible to reduce these costs by upgrading to a more efficient hot water system.


To be eligible to upgrade your hot water system and get a discount/rebate, you must:

  • be a Victorian household
  • have an inefficient electric or gas hot water system.

Your participation is voluntary.

New upgrades to be introduced

The VEU program regularly reviews the range of energy efficiency upgrades available to receive incentives to make sure they continue to reduce emissions and save consumers money. As part of these reviews, DEECA recently consulted on changes to the VEU program’s space heating and cooling and water heating activities.

Following this consultation, DEECA has announced the introduction of incentives to replace gas appliances with efficient electric alternatives. New incentives to upgrade from gas to electric appliances will be introduced later in the year, so we recommend regularly visiting the VEU industry latest news page for updates on these new products/activities.

How to organise your hot water system upgrade

You must engage an accredited provider to get a discount or rebate on a hot water system upgrade.

Accredited providers can:

  • use their tradesperson (if they have any available) to install the hot water system
  • work with a tradesperson of your choice to install the hot water system.

Note: the accredited provider is responsible for helping you obtain a discount or rebate for the upgrade.

They will be able to explain:

  • the steps to participate
  • what sort of products can you install to get a discount/rebate
  • the necessary qualifications of the tradesperson who installs the hot water system.

To check if a person or business is an accredited provider, go to the Essential Services Commission's VEU Registry of Accredited Persons and:

  • select the 'Business name' drop-down menu
  • scroll until you see the accredited provider you are searching for.

Tips when organising a hot water system upgrade

  1. Shop around. As with any market, it's worth shopping around and finding the right fit for your needs. Further information about choosing the right hot water system is available from Sustainability Victoria.
  2. Ensure the product's suitability. To get a rebate, you must install an approved product. Search the Essential Services Commission register of products for approved products.
  3. Accredited providers operate freely like any other businesses and can choose what upgrades they deliver, with some keeping waiting lists for activities and may contact you if circumstances change.

Remember to do your research on products. Not all products are of the same quality or suitability for all working environments.

*Discount/rebate will vary – these figures are based on a certificate price of $60 and the average efficiency of products improved under the program.

The final price will depend on several factors, including:

  • installation costs
