How much does a switchboard upgrade cost in Mildura?

What's included

• Removal of the old board
• New enclosure properly labelled
• Mains-rated main switch
• RCBO per circuit (combined RCD + circuit breaker)
• Certificate of Electrical Safety
• Compliance to AS/NZS 3000

What pushes the price above $1,900

• Meter box relocation if Powercor requires it — clearance rules sometimes force a move. Powercor flags it during the application stage and we add it into the quote up front, no surprise on the invoice.
• Mains tails or service pit work — older mains cabling may need replacing back to the pit, or the pit itself needs reworking to take new tails. Sighted on the site visit and quoted accordingly.
• Extra circuits added at the same time — sub-mains for a shed, granny flat, EV pre-wire, workshop. Each is quoted as a separate line item so you see exactly what it costs.

What it usually lands at

Most domestic ceramic swaps in Mildura land between $1,900 and $2,800 +GST. Anything quoted significantly outside that range deserves a question.

What's included

• Network application with Powercor or Essential Energy
• New three-phase enclosure
• Three-phase main switch and main MCBs
• Rebalancing of existing circuits across the three phases
• Compliance, labelling and Certificate of Electrical Safety

What pushes the price above $4,000

• Network application outcome — sometimes the supply pole or transformer feeding your street needs an upgrade. Powercor's decision, not ours.
• Distance from supply pole and underground vs overhead — long runs, especially underground, need trenching, conduit and pit work.
• Mains size and main switch upgrade — going to three-phase often pulls a 100A or larger main switch with it.
• Switchboard relocation — many older homes have the board in an awkward spot. Moving it during the upgrade costs less than doing it later.
• Asbestos backing board — some older boards are mounted on asbestos sheet. Specialist removal and dump fees apply when present.
• Sub-circuits added — EV charger circuit, shed feed, workshop, second air-con — quoted as separate line items.

What it usually lands at

A typical three-phase upgrade for a Mildura home with an EV charger added on the same job runs $5,500–$8,000 +GST all-in.

What's included

• Removal of the existing board
• New compliant enclosure (often larger than the original to handle modern load)
• Updated main switch, MCBs and RCBOs
• Relabelling and circuit identification
• Compliance to AS/NZS 3000
• Certificate of Electrical Safety

What pushes the price above $2,500

• Out-of-hours / trading-hour work — most cafes and shops can't shut for a day. We work overnight or on slow days. After-hours rates apply.
• Existing wiring condition — often the board upgrade surfaces old wiring that needs attention to stay compliant. We flag it and quote any rewire as a clean variation.
• Compliance items found on inspection — no RCDs across all circuits, exposed conductors, dodgy add-ons from a previous sparky. Listed with costs.
• Switchboard relocation — sometimes the existing board is in a customer-facing location that needs to move during a fitout refresh.
• Sub-circuit additions for kitchen, refrigeration, comms — quoted separately.
• Larger main switch or mains upgrade — modern commercial load (induction, refrigeration, big air-con) often needs more headroom than the old board can give.

What it usually lands at

A typical Mildura cafe board swap with an out-of-hours window and a couple of refrigeration upgrades runs $3,500–$5,500 +GST.

What's included

• Custom or off-the-shelf industrial enclosure
• Three-phase main switch, MCBs and motor protection devices
• Motor circuit isolation
• RCD compliance across applicable circuits
• Switchboard schedules and as-builts
• Certificate of Electrical Safety

What pushes the price above $8,000

• Number of motor circuits and protection required — each motor needs its own protection (DOL starter, soft-start or VSD). Motor count drives parts cost fast.
• Custom enclosure — food-grade, dust-rated, weatherproof IP-rated stainless or coated enclosures cost three to five times what a domestic enclosure costs.
• Shutdown window constraints — off-season scoping with after-hours mobilisation costs more than business-hours work.
• Network application size — larger boards often need a bigger supply, which means a Powercor or Essential Energy application with its own timeline and cost.
• Motor protection coordination — a selectivity study (making sure the right device trips first when a fault occurs) is required for compliant industrial design.
• Audit-ready documentation depth — switchboard reports, thermographic scans, as-builts, single-line diagrams. The documentation expected by insurers and auditors is well above residential.

What it usually lands at

Most Sunraysia industrial switchboard upgrades land between $10,000 and $18,000 +GST when documentation and shutdown scheduling are factored in.

• Certificate of Electrical Safety — included as standard. If a sparky doesn't issue one, you don't have a compliant board.
• Powercor or Essential Energy application costs — sometimes a separate fee, sometimes inside the quote. We tell you which.
• Defect rectification found on inspection — quoted as line items so you decide what to fix now versus later.
• Disposal of the old board — included.
• Out-of-hours rates — disclosed up front when needed.

• "Fixed price, no inspection needed" — risky on switchboard work; the actual scope only surfaces when the old board is opened up.
• No mention of certificate or compliance — a switchboard upgrade without a Certificate of Electrical Safety isn't a switchboard upgrade.
• A price that sounds too good — likely missing RCDs, missing labelling, or being installed by someone who isn't licensed to do the work.
• Verbal quote only — if it's not in writing, you have nothing to hold them to.
