Switchboard upgrades are one of the most-quoted jobs we do across Melbourne's eastern suburbs. The price band above reflects what to expect for a typical residential or small-commercial board replacement — the spread is wide because the underlying work scales with home size, age, and electrical complexity.
Reading the numbers
The median is more useful than an average for this kind of work — one or two outlier large jobs can pull averages up significantly. The p25–p75 range (the middle 50%) is the most reliable predictor: if your home is similar to what we typically work in (3–4 bedrooms, single-phase, no major mains issues), expect a quote in that band.
When to budget at the upper end
Three-phase + mains replacement + 15+ circuits is the combination that consistently pushes a quote above $3,000. If two or more of those apply, plan accordingly. We can usually phase the work — replace the board now, sort the mains in a follow-up appointment — if cash flow matters.
What's not in the price
This guide is for the upgrade itself. It doesn't cover new circuits added later (e.g. for an EV charger), cosmetic re-routing of cables, or any rectification of pre-existing wiring faults found during the upgrade. We flag those during the quote and price them separately so there are no surprises.
