This previous course covered some of the mandatory training outlined in the Victorian Essential Services Commission’s VEU scheme training requirements. It required VEU Retrofit Installers to complete the course in order to install low flow shower heads, weather sealing products and other products under the VEU scheme.
As at 01.01.2026 this is no longer a mandatory training requirement for VEU scheme Retrofit Installers.
