How much does a switchboard upgrade cost in Perth?
Quick answer
The cost of a switchboard upgrade depends on the existing board, circuit count, required RCD protection, wiring condition, access and whether new loads such as air conditioning or EV charging are being added. Send a clear switchboard photo and the outcome you need; we’ll confirm whether the next step is a written quote or an on-site assessment.
What affects the price
- Board size and circuit count: more circuits and higher amperage boards cost more to supply and fit.
- Condition of existing wiring: older ceramic-fuse boards sometimes reveal wiring that needs attention once the board is opened up.
- Added capacity: provisioning for a future EV charger or ducted air conditioning adds cost now but saves a second job later.
Getting a real number
Costs vary enough between properties that a written quote should follow an assessment of the existing board, required protection, access and the agreed scope rather than relying on a phone-only estimate.
