We work with local councils to hand-hold households, strata-committees and small businesses through the end-to-end process of electrification and reducing energy costs. Our program uses behavioural science and human centered design to make the process as easy as possible. We do not charge installers any commission or lead fees, and all advice provided to residents remains fully independent.
