Switchboard Upgrades in Kumeu, West Auckland
KR Electrical Services Ltd upgrades switchboards across Kumeu and West Auckland. If your home still has a ceramic fuse board or an old enclosure without RCD protection, it's a fire risk and most insurers won't cover it. Our EWRB team replaces old boards with modern, RCD-protected switchboards built to the current AS/NZS 3000 wiring standard. Work is completed in a single visit, usually half a day, and a Certificate of Compliance is issued on completion. We provide a fixed-price quote before any work starts, so there are no surprises on the invoice. We cover Kumeu, Huapai, Riverhead, Helensville, and all West Auckland suburbs.

Is a switchboard upgrade required for an EV charger?

- If your board is pre-2000 or has no RCDs, an upgrade is recommended before EV install
- We can quote both jobs together and complete in one visit
