• Renovation is the best time for rewiring and upgrades
• RCDs and smoke alarms are essential for compliance
• Energy efficiency can be improved during upgrades
• Qualified electricians are critical for safety and compliance

Understanding the Risks in Older Melbourne Homes

Melbourne is home to many timber and post-war houses. While these properties have stood the test of time, many contain original wiring and outdated systems. Common risks include:

• Old wiring insulation has deteriorated, posing fire hazards.
• Ceramic fuses that are no longer compliant with modern safety standards.
• Insufficient power capacity for today’s appliances and air-conditioning.
• Unprotected circuits that lack residual current devices (RCDs).

Electrical faults are among the leading causes of residential fires. Renovations are the perfect time to identify and fix these issues.

Key Electrical Safety Considerations During Renovation

Renovating an older home can be incredibly rewarding, the charm, the timber floors, the classic VJ walls. But while you’re busy planning paint colours and new kitchens, there’s one area you can’t afford to overlook: electrical safety.

Many homes across Melbourne, particularly those built before the 1980s, contain outdated or unsafe electrical systems that weren’t designed for today’s appliances, devices, and power usage. Whether you’re giving your home a light refresh or a full-blown makeover, here’s what you need to know to keep your reno safe, compliant, and risk-free.

1. Know What You’re Working With

Before picking up a sledgehammer, it’s crucial to understand the state of your home’s existing electrical setup.

Older Melbourne homes may have:

• Bakelite switches and fuses instead of modern safety switches and circuit breakers.
• Cloth-insulated wiring which becomes brittle and dangerous over time.
• Single circuits running too many power points or light fittings.
• No residual current devices (RCDs) or safety switches installed at all.

These systems may still function, but that doesn’t mean they’re safe, or legal under current Melbourne electrical standards.

2. Get a Pre-Reno Electrical Inspection

One of the first steps in any renovation should be to bring in a qualified electrician to do a full inspection of the property’s wiring and switchboard.

They’ll:

• Identify safety risks like old wiring or overloaded circuits.
• Check earthing systems (essential for safety in storms or faults).
• Ensure your switchboard meets current Melbourne regulations.
• Advise on upgrades that may be required if you’re adding new circuits, lights, or power points.

Tip: Don’t rely on DIY guesswork or what the previous owner told you. You’d be surprised how often “she’ll be right” turns into “house fire risk.”

3. Upgrade That Old Switchboard

Many older Melbourne homes still run off ancient fuse boxes that aren’t equipped to handle modern loads, think air-cons, dishwashers, dryers, and smart home systems.

A modern switchboard with:

• Circuit breakers
• Safety switches (RCDs)
• Surge protection

It is not only safer, but also often required by law if you’re renovating or making changes to the electrical system.

Bonus: Insurance companies may even reject claims if fire or damage was caused by faulty or outdated wiring. Upgrading protects your home and your wallet.

4. Never DIY Electrical Work

Melbourne law is crystal clear: only qualified electricians can carry out electrical work, even simple things like replacing power points, light switches, or installing ceiling fans.

DIY electrical work can result in:

• Fines of up to $40,000 for individuals.
• Dangerous faults leading to fires or electrocution.
• Non-compliance with building codes, delaying approvals or resale.

Stick to your strengths, leave the electrical work to the sparkies.

5. Plan Power Points and Lighting Properly

Older homes often have too few power points, forcing residents to rely on power boards and double adapters, a major cause of overloading and fire risk.

As part of your reno:

• Add more double or quad power points where needed.
• Install USB power points for device charging.
• Consider dedicated circuits for high-load appliances like ovens, air-cons, or pool pumps.
• Upgrade lighting to LED, they’re energy-efficient and reduce heat load in ceilings.

Tip: Plan, it’s cheaper and easier to add wiring while walls are open, rather than down the track.

6. Consider Smart Home Upgrades

While you’re updating the electrical system, it’s a great time to think about future-proofing. A lot of homeowners in Melbourne are now opting to integrate smart home tech, including:

• Smart lighting systems.
• Wi-Fi-enabled ceiling fans.
• Automated security cameras and intercoms.
• Energy monitoring tools.

These systems need proper cabling and safe installation, so mention them to your electrician early in the reno planning phase.

7. Watch for Asbestos and Old Insulation

Many older homes in Melbourne contain asbestos in walls, ceilings, and switchboards. Electricians know what to look for and will take precautions, but it’s another reason to never poke around in walls yourself, especially near electrical wiring.

Also, older homes may have insulation that’s not up to modern standards, or worse, insulation that touches wiring and causes a fire hazard. Get a licensed tradie to assess the condition before installing downlights or ceiling fans.

8. Install Smoke Alarms to Code

Melbourne has some of the strictest smoke alarm laws in the country. If you’re renovating or selling, you’ll need:

• Photoelectric smoke alarms
• Hardwired to mains power
• Interconnected, so when one goes off, they all do
• Installed in every bedroom, hallway, and level of the house

This isn’t just a box-ticking exercise, it’s a lifesaver. And a qualified electrician must do the installation.

9. Surge Protection Is a Smart Move

Melbourne gets its fair share of storms, and lightning strikes or power surges can fry your appliances in seconds.

Installing surge protection at the switchboard helps safeguard everything from your fridge to your laptop and solar inverter.

Energy Efficiency While Renovating

Electrical safety doesn’t just prevent hazards; it also enhances efficiency. By upgrading during renovations, you can:

• Install LED lighting for lower running costs.
• Add energy-efficient appliances.
• Explore solar and battery options to future-proof your property.

The Clean Energy Council advises that energy-smart renovations not only improve safety but also reduce long-term bills.

Working with Qualified Electricians

DIY electrical work is illegal in Melbourne and poses extreme safety risks. Only qualified electricians can perform wiring, switchboard upgrades, or safety checks. At Electrica Co., our Residential Electrical Services ensure renovations meet compliance and safety standards.

Professional electricians can:

• Conduct pre-renovation safety audits.
• Upgrade infrastructure to support modern appliances.
• Certify that work complies with Melbourne legislation.

Planning for the Future

When renovating, think beyond today’s needs. Modern households require circuits for:

• Electric vehicle charging stations.
• Smart home systems.
• Energy-efficient heating and cooling.

Incorporating these during renovations saves future expense and disruption. At Electrica Co., our electrical safety testing and inspection service provide insights into how to prepare your home for future needs.
