The Home Energy Efficiency Retrofits (HEER) method may be used to calculate energy savings from a range of household and small business energy efficiency upgrades. Eligible activities are listed in Schedules D and E of the ESS RuleIn this method, the term ‘energy’ may refer to electricity, gas or both.

A site assessment must be carried out at homes or small businesses wanting an upgrade.

Fact sheet requirements

A copy of the fact sheets below must also be given to the customer before they agree to an upgrade (i.e. before they sign the nomination form and the installation begins).

Implementation date

On or after 1 April 2024

All other HEER Activity Definitions

HEER Fact Sheet V2.0

You may need to provide 2 fact sheets if the upgrade involves a heat pump water heater and other activities.

We encourage you to start providing the HEER Heat Pump Water Heater Fact Sheet and HEER Fact Sheet V2.0 to customers before 1 April 2024 to help them make informed decisions.

It’s good practice to keep records as evidence of providing the fact sheet. Auditors will check the fact sheets have been provided during audit phone surveys.

  • Activity Definition E11 – Replace an Edison screw or bayonet lamp with an LED lamp for general lighting purposes
  • Activity Definition E13 – Replace T5 luminaire with a LED luminaire.

Further information on these requirements can be found on the Product acceptance page.

Water heater equipment requirements

Water heater equipment installed under the following activities of the HEER Method must be accepted by the Scheme Administrator as meeting the equipment requirements:

  • Activity Definition D17 - Replace an existing electric water heater with an air source heat pump water heater
  • Activity Definition D18 - Replace an existing electric water heater with a solar (electric boosted) water heater
  • Activity Definition D19 - Replace an existing gas water heater with an air source heat pump water heater
  • Activity Definition D20 - Replace an existing gas water heater with a solar (electric boosted) water heater

Where more than one water heater is being installed at a site, the evidence must clearly show the number of water heaters replaced, which must be equal to the number being installed (e.g. 2 gas water heaters being replaced by 2 heat pump hot water heaters).

Chimney damper equipment requirements

Chimney dampers used in Activity Definition E9 of the HEER method must be accepted by the Scheme Administrator as meeting the equipment requirements. See the Product acceptance page for more information.
