Frequently asked questions

How much does a switchboard upgrade cost in Hamilton? +
Most residential switchboard upgrades range from about $1,500 to $5,000 depending on the size of the board, RCD requirements and the condition of your wiring. We provide a fixed quote before any work begins.
Are old ceramic fuses still safe? +
Old ceramic and rewireable fuses offer no RCD protection and are no longer compliant for new work under AS/NZS 3000. We recommend upgrading — especially before adding EV or heat-pump loads.
Do I need an upgrade before an EV charger or heat pump? +
Often yes. These add significant load, and many older boards can't safely accommodate them. We'll check your board as part of the quote.
