Licensed work

Check their licence

Solar and batteries have to be installed by an accredited installer and wired by a licensed electrician. The federal discounts only apply with accredited installers and products. Ask for their licence number, then look them up on Access Canberra's public register. It shows expired, suspended and cancelled licences, and any disciplinary action.
