A switchboard upgrade in Perth typically costs between $1,500 and $3,500, depending on the size of your home, how many circuits you have, and whether the old board has any surprises behind it. A straightforward swap of an old fuse board for a modern, RCD-protected switchboard usually lands in the $1,500–$2,200 range; bigger homes, extra circuits or asbestos backing push it higher.
What you’re actually paying for
A compliant switchboard upgrade isn’t just a new box on the wall. It includes:
- A modern enclosure with clearly labelled circuits
- Safety switches (RCDs) protecting your power and lighting circuits
- Circuit breakers correctly sized for your loads
- Surge protection (optional but worth it)
- Tidy, compliant wiring that meets the current AS/NZS 3000 Wiring Rules
- The WA electrical safety certificate paperwork (preliminary and completion notices) lodged where the job requires it
What pushes the price up
- Asbestos backing board: common in older Perth homes. Safe removal adds roughly $800–$2,000.
- More circuits: adding dedicated circuits for an oven, air-con, EV charger or extension.
- A meter or mains upgrade: if the job touches the meter or consumer mains it involves the network side, which we coordinate with the network distributor so you are not chasing a second trade.
When should you upgrade?
If your board still has ceramic fuses, no safety switches, scorch marks, or it trips whenever you run the kettle and the heater together, it’s time. Older boards lack RCD protection and struggle with modern loads, both a safety risk and a daily annoyance.
How we price it
We assess your board, talk through what you need, and give you a clear fixed price before any work begins, so the figure you agree to is the figure you pay. See our pricing guide for typical figures, or request a callback and we’ll talk through your job.
