5 Things Melbourne Electricians Wish Homeowners Knew Before Renovating
Renovating in Melbourne? Here are the 5 electrical mistakes EAY Electrical sees most often — and how to avoid an expensive rework once the walls are closed up.
Every renovation season, EAY Electrical gets the same call: a homeowner is mid-renovation, the walls are about to close up, and suddenly there's an electrical decision that should have been made weeks ago. Most of these moments are avoidable. Here are the five things we wish every Melbourne homeowner knew before the first wall comes down.
1. Check Switchboard Capacity Before You Plan New Circuits
A new kitchen island, a home theatre, ducted air conditioning — every new circuit draws on your switchboard's capacity. Many older Melbourne homes are running on switchboards that are already near capacity, or still using ceramic fuses with no safety switches at all. Get your switchboard assessed before you finalise renovation plans, not after the electrician arrives to find there's no room left.
2. Pre-Wire for an EV Charger and Battery Even If You Don't Need One Yet
If you're already opening up walls or a garage during a renovation, running conduit for a future EV charger or home battery costs a fraction of what it costs to retrofit later. We see homeowners regret this constantly — a beautifully finished garage that now needs to be reopened for a cable run that would have taken twenty minutes during the original build.
3. Safety Switches Are Not Optional
Under Victorian regulations, safety switches (RCDs) are required on relevant circuits in most renovation and new work. This isn't a nice-to-have that gets value-engineered out of a tight budget — it's a legal requirement and a genuine safety issue. If your quote doesn't include compliant safety switches, ask why.
4. Interconnected Smoke Alarms Are Required in Most Renovations
Victorian smoke alarm requirements have tightened, and most renovations trigger a requirement for interconnected, photoelectric alarms — meaning if one alarm goes off, they all do. This is frequently missed by homeowners managing their own trades, and it's a compliance issue that can hold up a final inspection.
5. Get Your Electrician In Before the Walls Close, Not After
The single most expensive electrical mistake in any renovation is deciding on power point placement, lighting layout, or additional circuits after the plasterboard is up. Reopening a finished wall to add a circuit costs many times more than planning it in during the rough-in stage. If there's any chance you'll want something electrical later — extra power points, pendant lighting, a future EV charger — plan for it now.

When should I involve an electrician in my renovation?
Ideally before final plans are locked in, and definitely before any walls are closed up. Electrical rough-in needs to happen before plastering.
Do I legally need safety switches during a renovation?
Yes, safety switches are required on relevant circuits under Victorian regulations for most renovation and new electrical work.
Is it worth pre-wiring for an EV charger if I don't own an EV yet?
Yes, if you're already opening walls or a garage. Running conduit during a renovation is far cheaper than retrofitting after the space is finished.
What smoke alarm rules apply to Melbourne renovations?
Most renovations trigger a requirement for interconnected, photoelectric smoke alarms, meaning all alarms in the home activate together.
