Switchboard upgrades are one of the most common electrical jobs in Perth homes, particularly in properties built before the 1990s. If you have been quoted for one and want to understand what you are actually paying for, or you suspect your switchboard may need replacing but are not sure, this guide covers what you need to know.
Why switchboards need upgrading
Older switchboards were built for a fraction of the electrical load that modern homes run. Air conditioning, electric vehicle chargers, induction cooktops, solar inverters, and multiple high draw appliances running at once put real pressure on ageing switchboards that were never designed for it. The other issue is safety. Older ceramic fuse boards do not have the safety switches required under current Australian standards, which means they offer no protection against electrocution from a faulty appliance or wiring fault.
If your home still has a ceramic fuse board with individual fuse wires rather than circuit breakers and safety switches, upgrading is not optional from a safety standpoint. It is overdue.
What does a switchboard upgrade cost in Perth?
Most residential switchboard upgrades in Perth start from $1,760 inc GST for a single phase board and from $2,090 inc GST for three phase. The main factors that push the price above the starting figure are:
- The number of circuits in your home and whether new circuits need to be added
- Whether the existing metering and main switch need to be relocated or replaced
- The condition of the existing cabling and whether any remedial work is needed
- Whether solar, battery storage, or an EV charger is being integrated at the same tim
What is included in a switchboard upgrade?
A full switchboard upgrade from a licensed electrician includes removal of the old board, supply and installation of a new consumer mains panel with current circuit breakers and safety switches, correct labelling of all circuits, and a compliance test to confirm the installation meets the Australian Standard AS/NZS 3000.
The work requires a Certificate of Compliance from the licensed electrician on completion, which you should keep with your property records. This is a legal requirement in Western Australia, not optional.
When should you get a quote?
