We service Perth CBD, Joondalup, Rockingham, Fremantle, Midland, and surrounding Perth metro suburbs, plus industrial precincts across the wider WA region.
Are you licensed and insured?
Yes. Diamper is a licensed WA electrical contractor (EC012908), a CEC Accredited Solar Installer, and a NECA member.
Do you handle both electrical and solar/aircon work, or do I need separate contractors?
One team handles all of it. The same licensed electricians deliver wiring, solar integration and aircon circuits, so you're not coordinating between separate contractors for connected work.
