The Box Hill picture
The electrical work we do in Box Hill is shaped by what the suburb is built from. Box Hill is a genuinely mixed suburb — postwar and interwar houses, extensive medium and high-density redevelopment around the station, and a large commercial centre, and an installation put in for that housing is rarely what the same house is asked to carry now.
The dominant driver of this work in Box Hill is commercial fitout and tenancy change more than anything else, alongside renovation of the remaining postwar housing.
What turns up in Box Hill
Across Box Hill the pattern is consistent: postwar house boards with asbestos panels, and commercial tenancy boards that have been reconfigured repeatedly as the centre has redeveloped.
None of that is unusual, and none of it is a reason for alarm on its own. It does mean an assessment is worth more than a phone estimate, because what matters is the combination of what is there and what you are about to ask of it.
What the work involves
Going from single-phase to three-phase is not a switchboard job with a bigger board on the end of it. The distributor has to provide the additional phases at the point of attachment, the consumer mains have to be replaced with cable rated for the new supply, the main earth and the earthing system have to be brought up to current requirements, and the switchboard has to be rebuilt around a three-phase main switch with the existing circuits balanced sensibly across the phases. Where the meter box also has to move — because the existing position will not take a larger enclosure, or the run is too long — that becomes part of the same job rather than a separate one.
What usually brings it forward
In Box Hill the common triggers are:
- a ducted air conditioning system the existing supply cannot carry
- an EV charger — or a second one — on a house already close to its limit
- an induction cooktop replacing gas, often alongside a full kitchen renovation
- a workshop, pool, lift or pottery kiln with a genuine three-phase load
- a second storey or large extension that roughly doubles the connected load
Any one of them on its own is enough. More often it is two or three arriving together, which is why the job is usually bigger than the thing that prompted the call.
The part specific to Box Hill
The commercial centre means a lot of the work here runs to lease dates and handover programmes rather than to a homeowner's timeline.
What to expect on the day
Expect the supply to be off for a substantial part of the day, and expect the distributor to be involved — the additional phases are their work, not ours, and their attendance has to be booked rather than assumed. We tell you honestly which parts of the timeline we control and which we do not. Where the existing board can be re-used as a sub-board it will be, and where it cannot we say so before the job rather than after it.
Why it is worth doing properly
The reason to do it properly is that a supply upgrade done halfway just relocates the bottleneck. Putting a larger board on undersized mains, or adding phases without rebalancing the circuits, produces an installation that looks upgraded and behaves exactly as it did before. We assess the whole path from the point of attachment in.
Nearby
We cover the east generally, and the same work in the suburbs either side of Box Hill: Balwyn, Doncaster, Glen Waverley. If your property is close to a boundary it makes no difference to us — it is the same van and the same day rate.
What it costs
Three-phase work is priced per project after a site inspection, because the cost is driven by the run length from the point of attachment, whether the distributor has to attend, and what the existing switchboard can be re-used for.
Quotes are free, fixed-price and given after a site inspection. What is quoted is what is paid, and a Certificate of Electrical Safety is issued on completion.
Whether three-phase is actually the right answer is worth establishing before anything is quoted — sometimes a single-phase supply upgrade and a rebuilt board does the same job for considerably less.

How do I know if I actually need three-phase in Box Hill?
You need it when the connected load genuinely exceeds what a single-phase supply can carry, or when a specific appliance requires it. Plenty of properties that ask for three-phase are better served by a single-phase supply upgrade and a rebuilt board, which costs considerably less. We tell you which applies before quoting.
Does the electricity distributor have to be involved?
Yes. The additional phases are provided by the distributor at the point of attachment, and their attendance has to be booked. That part of the timeline is outside our control and we are upfront about it.
How long is the power off for a Box Hill three-phase upgrade?
Expect a substantial part of a day. The exact outage depends on whether the mains and meter box are being replaced at the same time, which on most older properties they are.
