When to Upgrade Your Switchboard: A Geelong Homeowner's Guide

Your switchboard is the heart of your home’s electrical system. It takes the supply from the street and splits it safely into the circuits that run your lights, power points, oven, hot water and air conditioning. In many Geelong homes — especially the post-war weatherboards around Belmont and the older brick veneers through Newtown and Highton — that switchboard is decades old and was never designed for the way we live today.

Here’s how to tell when it’s time for an upgrade, what’s involved, and what you can expect to pay.

Signs your switchboard needs upgrading

• Ceramic fuses with rewirable fuse wire. If you’re still twisting fuse wire when a “fuse blows”, your board predates modern safety standards.
• No safety switches (RCDs). Safety switches cut power in milliseconds when they detect a fault through a person. Boards without them leave you exposed.
• Frequent tripping or blown fuses. Often a sign your board is overloaded by modern appliances.
• A board that’s full. No spare ways means no room to add a circuit for an air conditioner, EV charger or renovation.
• Scorch marks, buzzing or a burning smell. Stop using affected circuits and call an electrician immediately.

Why it matters in Victoria

Since modern wiring rules came in, new and renovated homes must have safety switches on power and lighting circuits. Older Geelong homes were often wired before this, so an upgrade is the single most effective safety improvement most owners can make. It’s also frequently required before adding solar, a battery or an EV charger.

What a switchboard upgrade involves

A typical upgrade means replacing the old enclosure with a modern board, fitting a main switch, RCD safety switches and circuit breakers, re-terminating your circuits neatly, labelling everything clearly, and testing the lot. We then issue a Certificate of Electrical Safety.

What does it cost in Geelong?

As a guide, switchboard upgrades typically range from $800 to $2,500. The final figure depends on how many circuits you have, whether the existing wiring needs remedial work, and whether the board location or meter setup needs to change. We always quote upfront and fixed — no surprises.
