Electrical Issues to Fix When Renovating an Older Home

February 14, 2025

Renovating an older home in Melbourne can be an exciting yet challenging process. While you may be eager to update the aesthetics, it is crucial to prioritise electrical safety and compliance. Many older homes were built before modern electrical standards were in place, meaning they often contain outdated wiring, faulty switchboards, and potential fire hazards.

At Legacy Trade Services, your trusted electrical and air conditioning partner in Melbourne, we understand the complexities of older home renovations. In this guide, we will explore the key electrical issues you must address before starting your renovation project.

1. Outdated Wiring: A Major Safety Hazard

Older homes often have wiring that does not meet current Australian standards. Some of the most common outdated wiring systems include:

VIR (Vulcanised Indian Rubber) wiring: This type of wiring was used in homes built before the 1960s and deteriorates over time, increasing the risk of electrical faults and fires.
Cotton-insulated wiring: Common in homes built before the 1950s, this wiring lacks proper insulation, making it a serious fire hazard.
Aluminium wiring: Found in some mid-century homes, aluminium wiring is prone to overheating and corrosion, which can cause electrical failures.

What to Do:

Before proceeding with your renovation, have a licenced electrician inspect the wiring. If your home has any of these outdated wiring systems, a full or partial rewiring may be necessary.

2. Overloaded and Outdated Switchboards

Older switchboards were not designed to handle the electrical demands of modern households. If your home still has an outdated switchboard, you may experience:

Frequent tripping of circuit breakers
Blown fuses
Flickering lights
Overheating switchboard components

What to Do:

A switchboard upgrade is essential to accommodate modern appliances and improve electrical safety. A modern switchboard with safety switches can protect your home from electrical faults and reduce the risk of electrical fires.

3. Lack of Safety Switches

Many older Melbourne homes were built before safety switches became mandatory. Safety switches are designed to detect electrical faults and shut off power to prevent electrocution and fire. Without them, your home is at a higher risk of electrical accidents.

What to Do:

Ensure your switchboard includes RCD (Residual Current Device) safety switches on all circuits. If your home lacks these devices, an electrician should install them as part of your renovation.

4. Insufficient Power Points and Overloaded Circuits

Older homes often have limited power points, leading to excessive reliance on power boards and extension cords. This can result in:

Overloaded circuits
Increased fire risk
Tripping of circuit breakers

What to Do:

As part of your renovation, consider adding more power points in key areas such as the kitchen, living room, and bedrooms. USB power points can also be a great modern addition.

5. Inefficient or Non-Compliant Lighting

Older homes may have inefficient lighting fixtures that do not meet current energy efficiency standards. Halogen or incandescent bulbs consume more power and produce excessive heat, contributing to higher energy bills and safety risks.

What to Do:

Upgrade to LED lighting, which is more energy-efficient, long-lasting, and safer. An electrician can help you install new light fittings that enhance both safety and aesthetics.

6. Old or Faulty Electrical Panels and Fuses

If your home still has an old fuse box instead of a modern circuit breaker panel, it is time for an upgrade. Fuse boxes can be dangerous because:

They require manual replacement of fuses.
They do not provide adequate protection against power surges.
They may not comply with current electrical standards.

What to Do:

A licenced electrician should replace your old fuse box with a modern circuit breaker panel. This will improve electrical reliability and reduce fire risks.

7. Poor Earthing and Bonding

Proper earthing is essential for electrical safety, preventing electric shocks and reducing the risk of power surges. Many older homes have inadequate or deteriorated earthing systems, putting occupants at risk.

What to Do:

During your renovation, have an electrician check and upgrade your home's earthing and bonding system to meet current safety standards.

8. Electrical Compliance and Permits

When renovating an older home in Melbourne, all electrical work must comply with Australian Standards (AS/NZS 3000). Any modifications or upgrades require proper permits and certifications.

What to Do:

Always engage a licenced electrician like Legacy Trade Services to ensure your renovation meets all legal and safety requirements. A compliance certificate should be issued upon completion of electrical work.

Renovating an older home presents a unique set of challenges, particularly when it comes to electrical systems. Addressing outdated wiring, upgrading the switchboard, installing safety switches, and ensuring proper earthing are all crucial steps to modernise your home safely.

10 Electrical Safety Tips At Home

By Brandon Caspersz • September 11, 2025

Electricity powers every part of the home, from lights to portable heaters and everything in between. Behind the walls, switches, power points, wires, and the switchboard are doing their job. While it's easy to enjoy the comfort and convenience this brings, have you thought about the hidden dangers it might pose? The safety of your home and your family's health depend on understanding how to handle electricity. You want to protect what you love and ensure the space is as secure as possible. Here are the top 10 electrical safety tips at home to help prevent fires, shocks, and other hazards. 1. Make Sure There Is Space For Air To Circulate Around Appliances. Electrical appliances heat up when in use, so many are designed with vents to help them cool down. Place these devices in areas with sufficient space for air circulation to prevent overheating. The right power installation may not be enough. Consider using electrical safety equipment such as surge protectors or thermal cut-offs for added protection against potential risks. Never put items on top of appliances like microwaves or operate them inside enclosed cupboards. Some kitchens have built-in appliances, but this is only safe if installed by professionals using devices designed for such placement. These appliances feature venting systems that enable air to circulate effectively, reducing the risk of overheating and electrical accidents. 2. Take Out The Plugs Of All Appliances When Not In Use. Here's one of the most basic electrical safety tips at home that's also easy to forget: when you're not using an appliance, unplug it. This not only saves power by reducing standby drain but also keeps them safe from overheating or power surges . People often forget to unplug appliances they're not using, but the latest smart plugs offer a solution. These plugs allow you to create power schedules for each power point. 3. Childproof All The Power Points. Take extra care with power points, even if kids aren't supposed to be in that specific area. Cover points to prevent shocks to support electrical safety for kids. Kids might try to poke their fingers or other things into power points, so it's key to keep them covered when not in use. Also, teach kids the safe use of electricity and make it clear why they should never put leads or electrical items in their mouths. 4. Don't Overuse Extension Cords
