As a rough guide, a domestic switchboard upgrade in Perth usually falls somewhere between $1,200 and $3,000, with most standard homes landing in the middle of that. The price depends on how many circuits are being carried across, the condition of the existing wiring, and whether the main switch and supply need attention.

The switchboard is the least interesting part of a house and quietly the most important. It is also the part that decides whether you can add an air conditioner, a charger or a second oven without something tripping every time you use it.
How do I know if mine needs upgrading?
There are a few reliable signs, and none of them require a technical background to spot.
- Ceramic fuses or fuse wire. If you have ever rewired a fuse by hand, your board predates modern protection by several decades.
- No safety switches, or only some. Plenty of homes have RCD protection on the power circuits but not the lighting, which is a common gap in older installations.
- No spare capacity. If the board is physically full, nothing new can be added without work.
- Repeated tripping. A breaker that keeps going off is telling you something, and resetting it is not an answer.
- Buying, selling or leasing. Property transactions are one of the most common triggers, because RCD and smoke alarm requirements get checked.
What does the work actually involve?
An upgrade replaces the old board with a modern enclosure, carries the existing circuits across onto individual breakers with RCD protection, labels everything properly, and leaves room for whatever gets added later. The power is off for part of the day, and you will be told in advance for roughly how long.
It is worth saying that a good switchboard upgrade is as much about the labelling and the spare capacity as the protection. A board nobody can read is a board that costs money every time an electrician has to work on it.
What changes the price?
- Circuit count. More circuits means more breakers, more terminations and more time.
- The state of the existing wiring. Old cabling that is brittle or undersized may need attention at the board end.
- Main switch and supply. Sometimes the incoming side needs work too, which is a different conversation and occasionally involves the network.
- Location and access. A board in a tight meter box takes longer than one on an open wall.
- Asbestos backing. Some older boards are mounted on material that needs careful handling, which affects both method and cost.
Do I have to do it right now?
Sometimes yes, often no. A board with no RCD protection at all is a genuine safety issue and worth dealing with promptly. A board that is simply old but sound may have years left in it. The useful thing is to get an honest assessment rather than a scare, and that is a reasonable thing to ask for when you book a quote.
Is it worth doing before other work?
Usually. If you are planning an EV charger, solar, air conditioning or a renovation, doing the board first means the rest of the work has somewhere to land. Doing it afterwards often means paying twice for the same access.
