When Do You Need an Upgrade?
Your home likely needs a switchboard upgrade if it has ceramic fuse holders, no RCDs (safety switches), frequent fuse-blowing, or if you're adding an EV charger, solar system, heat pump, or induction cooktop. Older fuse boards simply don't have the capacity for modern high-draw appliances.
What's Included
A full upgrade includes: replace fuse board with modern circuit breaker panel, install RCDs on all circuits, label and test, issue Electrical Certificate of Compliance (eCoC). Must be done by a registered electrician.
