Switchboard upgrades Melbourne: what they cost and whether you need one
A switchboard upgrade replaces an old fuse box or main switchboard with a modern board of circuit breakers and safety switches (RCDs). With Helcro Electrical in Melbourne’s South East, a home switchboard upgrade is typically $1,250 to $2,500 including GST, with a small board at the low end.
Not every home needs one, and if yours doesn’t, we’ll tell you. We can often give an indicative price by phone, at no cost; your written quote follows a $50 site assessment.

What a switchboard upgrade costs, and what moves the price
Your written quote confirms the price. What moves it:
- The board: its size, its number of circuits, and how easy it is to reach. We use components from Hager, Schneider, Clipsal and Sprecher.
- Safety switches: a replaced board needs them on all final sub-circuits.
- What's behind an old board: an asbestos backing board, the earthing, or wiring faults that new safety switches bring to light.
If a wiring fault turns up, we tell you what it needs and agree the price before doing more.
The range is for upgrading the board. New consumer mains, meter box work or a three-phase supply go in your written quote. Any charges your distributor makes for its own work are separate.
We found no current Victorian Energy Upgrades or Solar Victoria rebate that pays for a home switchboard upgrade on its own.
Comparing quotes? Check that each says what's included, safety switches on every circuit, the independent inspection and certificate, what happens if asbestos or a wiring fault turns up, and the contractor's registration number. Energy Safe Victoria's public register lists contractors.
Do you need a switchboard upgrade? Required, advised or neither
- You own and live in it. We know of no Victorian rule that makes an owner-occupier replace a working old fuse box or add safety switches just because the home is old; the requirements apply when electrical work is done. Not required isn't the same as safe: Energy Safe Victoria lists "old switchboards, particularly those without a safety switch" among its warning signs, so if you have no safety switch we'd advise adding that protection. It also says to check the wiring in a house over 30 years old.
- An electrician finds it unsafe. An unsafe installation has to be made safe, and the Government's Power Up Your Home says a "non-compliant or potentially unsafe switchboard" found during electrification "will need to be upgraded by law".
- You rent it out. Separate rules apply (below).
- You're adding a circuit. The new circuit needs safety switch protection, and we know of no rule that adding one by itself forces work on your other circuits.
- One device has failed. Repairing one component, or swapping one circuit breaker, RCD or RCBO for an equivalent one in the same spot, needs no inspection, only a non-prescribed Certificate of Electrical Safety.
The $50 site assessment, then a written quote
For $50 including GST we check your board and anything you plan to add, tell you whether it needs replacing and, if it does, give you a written quote.
The inspector, the power and your Certificate of Electrical Safety
Replacing the main switchboard in a Victorian home is prescribed electrical work. It needs a prescribed Certificate of Electrical Safety and an inspection by an independent Licensed Electrical Inspector, and the power can't go back on until that inspection is done. Your contractor arranges the inspector; on our jobs, we do that for you.
You receive a Certificate of Electrical Safety. It records the work done; it isn't a whole-home safety check.
Is my switchboard safe? Signs it needs a look
Energy Safe Victoria's tell-tale signs that your wiring may be faulty are:
- old switchboards, particularly those without a safety switch
- old power switches or power points, particularly broken ones
- flickering lights
- sparks from switchboards, switches or power points
The CFA lists "tripping circuit breakers and blowing fuses" as signs of an overloaded circuit.
If you see sparks or smell burning, keep clear and call 1300 201 358 (Monday to Friday 8:00am to 6:00pm, Saturday 8:00am to 1:00pm); we will confirm availability directly. Outside those hours, call your distributor's faults line: United Energy 132 099, CitiPower 13 12 80. If there's smoke or fire, get out and call 000.
Buying a home built before the 1980s? Energy Safe Victoria says it is "imperative the wiring is checked" before you move in.
Asbestos. Some older switchboards and meter boards have an asbestos backing board, and most were installed before 1990. You can't confirm it by looking, only a NATA-accredited lab can, so don't drill, cut or sand an older board. If one needs to come out, the Victorian Asbestos Hub recommends a licensed removalist for any amount, and says friable (crumbly) asbestos requires a Class A licensed removalist.
Old fuse box or ceramic fuses: when to replace them
"Fuse box" is the everyday name for an older board with fuses instead of circuit breakers. Ceramic (rewireable) fuses are plug-in units with a length of fuse wire: when one blows, the wire has to be replaced, where a circuit breaker can be reset.
Have it checked when fuses keep blowing: the cause may be an appliance or the wiring, not the board. Replace it when it can't take a circuit you're adding, or when a rental needs it. A fuse box upgrade gets you circuit breakers and safety switches on every circuit. If a fuse has blown, read our ceramic fuse guide first.
Fuse box, consumer mains or meter box: who does which job
"Upgrade" can mean a board swap, new consumer mains, meter box work or a bigger supply. Under the Victorian Service and Installation Rules (May 2026):
| Part | What it is | Whose it is, who works on it |
|---|---|---|
| Service line and service fuse | The line and fuse feeding your home | Your distributor's; an electrician may not upsize the fuse |
| Consumer mains and mains connection box | The cables from the point of supply to your main switchboard, and where an overhead line meets them | Yours; a licensed electrician |
| Meter | Measures your electricity | Your metering provider's, normally your distributor |
| Meter box or panel | Holds the meter | Yours, though an old timber panel may be the distributor's; a licensed electrician |
| Main switchboard | Main switch, circuit breakers, safety switches | Yours; a licensed electrician |
For your parts, you must engage a registered electrical contractor, whose licensed electrician does the work and issues a Certificate of Electrical Safety. Doing it yourself, Energy Safe Victoria says, "it's illegal and it can also be deadly".
Your distributor. Across nearly all our area that's United Energy; part of Caulfield North is on CitiPower, and your bill names your distributor.
Three-phase power. Moving from single-phase to three-phase is a change to your connection: your contractor applies to your distributor, which assesses the request and does its part. The Victorian Government's Power Up Your Home says "Homes don't need a 3-phase connection to switch to all-electric appliances", and a larger single-phase connection "is often substantially cheaper".
Switchboard upgrades for an EV charger, solar, battery, hot water or cooktop
Planning one of these, or going all-electric, is a reason to check the board, not proof you need a new one.
- EV charger. Power Up Your Home says "For most electric vehicle (EV) charging needs, single-phase power is sufficient", and a 7.2kW charger "can still operate on a 63-amp single-phase connection". United Energy says "A typical 22kW fast charger requires three phase power". To see if your switchboard is ready, your electrician checks its space and protection for the new circuit, works out the new maximum demand and checks your connection can carry it. Our EV charger page has the brands we install.
- Solar. Before solar is added to an existing switchboard, the board must be assessed, because it may need altering or upgrading.
- Battery. A battery doesn't automatically mean a new switchboard, but your electrician must assess the board first.
- Hot water or split system. A heat pump hot water system or split system may need its own circuit, per the manufacturer's instructions. If it adds load, your electrician must work out the new maximum demand and check the board's capacity and spare slots.
- Induction cooktop. The Government's buyers guide says one may need a new dedicated circuit, "or even a switchboard upgrade if no new circuits can be added". See our cooktop guide.
Rental properties: the rule since 29 March 2023
From 29 March 2023, every power outlet and lighting circuit in a Victorian rental must connect to a switchboard-type circuit breaker (AS/NZS 3000) and a switchboard-type safety switch (RCD). Consumer Affairs Victoria says the standards don't apply if a rental agreement became periodic (month to month) before 29 March 2021. Any new agreement has to meet them.
Consumer Affairs Victoria says a board with circuit breakers can meet the standard if the electrician adds circuit breaker components to the power outlet and lighting circuits, "without the need to add to or modify the circuit protection to other circuits". Older properties with "a panel and fuse board or a federal fuse board" may have to replace the entire switchboard, with circuit breaker components on all circuits.
Our rental safety checks section has the dates. The energy standards starting 1 March 2027 are separate.
Safety switches: what they do and how to spot one
Fuses and circuit breakers protect against short circuits and overloads; a safety switch is the device designed to protect people from electric shock, and an RCBO combines both in one unit. Energy Safe Victoria says a safety switch "always has a test button and '30ma' printed on them".
They've been required on new domestic wiring since the early 1990s (power points) and from 2001 (lighting too), so an older home may have none unless it has been upgraded (the dates in full).

Switchboard upgrade questions
What is a switchboard?
The panel where your home’s power splits into circuits, each protected by a fuse or circuit breaker.
Can you upgrade a switchboard without rewiring the house?
An upgrade replaces the board, not the wiring in your walls. A new board may bring existing faults to light; any rewiring that follows is quoted in writing.
What is the new standard for switchboards in Australia?
Part 1 of the AS/NZS 61439 series, which covers how switchboards are built, was updated in 2026 (AS/NZS 61439.1:2026). In Victoria, switchboard work must meet the Wiring Rules (AS/NZS 3000:2018, with Amendments 1, 2 and 3).
How long does a switchboard upgrade take?
It depends on the board and what needs replacing. After a main switchboard replacement the power stays off until the inspection is done, so we arrange for the inspector to attend at an agreed time before the power goes back on. We go through the timing when we quote.
