"How much will it cost?" is the first question every homeowner asks, and it's also the hardest to answer with a single number — because switchboard upgrades range from a straightforward panel swap to a full three-phase conversion with consumer mains replacement.
What Drives the Price
The biggest cost factors are supply capacity (a straightforward like-for-like panel replacement is cheaper than a 63A to 200A upgrade), whether you're converting from single-phase to three-phase power, the condition and length of your existing consumer mains, and whether metering also needs replacing.
A modern switchboard also needs safety switches on every circuit and surge protection to meet current AS/NZS 3000 wiring rules — if your existing board predates these requirements, bringing it up to standard adds to the scope.
Why Fixed Quotes Beat Estimates
Because so much depends on what's behind the existing board — cable condition, access, whether the meter position needs to change — a proper quote requires a site inspection, not a phone estimate. We provide fixed, itemised quotes before any work begins, so there are no surprise costs once the job is underway.
Most switchboard upgrades are completed in a single day, including the outage window coordinated with your network operator, keeping labour costs predictable.
