In this article, we’ll explore why wiring upgrades are essential for older homes, the risks of leaving old systems untouched, and how a modern electrical system can improve safety, efficiency, and convenience.
Understanding the Wiring in Older Homes
Many homes built before the 1980s still use wiring systems that were common at the time—like knob-and-tube or aluminium wiring. While these methods were state-of-the-art in their day, they were never designed to handle the electrical demands of modern households with air conditioning, high-speed internet, home entertainment systems, and multiple kitchen appliances.
Older systems may also lack grounding or safety switches (RCDs), putting occupants at greater risk of electric shocks and fire.
Top Signs Your Home May Need a Wiring Upgrade
Here are some warning signs that your home’s wiring may be outdated:
- Frequent blown fuses or tripped circuit breakers
- Flickering or dimming lights
- Buzzing or sizzling sounds from power outlets
- Discoloured or warm wall outlets
- Unexplained burning smells
- Two-prong (ungrounded) power outlets
- Lack of safety switches or circuit breakers
If you’re noticing any of these symptoms, it’s time to consult a licensed electrician.
Why Wiring Upgrades Are Critical for Safety
1. Fire Risk from Faulty Wiring
Aged or damaged wiring is one of the leading causes of residential fires in Australia. In fact, the Queensland Fire and Emergency Services consistently reports that electrical faults are a major contributor to house fires. Old insulation can become brittle, exposing live wires that arc and ignite.
Modern wiring systems, when properly installed by certified electricians like the team at J&B Electricals, significantly reduce this risk through grounded connections and safety devices such as RCDs and circuit breakers.
2. Increased Electrical Load
Today’s families use more electricity than ever before. From laptops and smart TVs to microwaves and EV chargers, the power demand has grown exponentially.
Older systems were often built to handle just 30 to 60 amps, whereas modern households typically require 100 amps or more. Without an upgrade, your system could be constantly overloaded, leading to overheating or circuit failures.
The Benefits of Modern Electrical Systems
1. Improved Safety
Upgrading your wiring means better protection against electrical faults, shocks, and fires. Modern systems include:
- Residual Current Devices (RCDs) that cut power in milliseconds during a fault
- Circuit breakers to prevent overloads
- Proper grounding to reduce shock risk
2. Enhanced Energy Efficiency
Modern wiring, when paired with energy-efficient appliances and LED lighting, helps reduce your energy consumption. It also minimises phantom loads—power drawn by devices in standby mode—by ensuring circuits operate at optimal capacity.
3. Greater Convenience and Functionality
Upgraded systems can include:
- More power points in convenient locations
- USB outlets for modern devices
- Better support for home automation systems
- Separate circuits for heavy-duty appliances
This leads to a more comfortable and functional living space without needing power boards or extension cords cluttering every room.
4. Boosted Property Value
Whether you’re planning to sell soon or not, an electrical upgrade adds significant resale value to your home. Buyers are more confident in homes with modern electrical systems and up-to-date safety features.
5. Compliance with Modern Standards
Queensland’s electrical regulations have evolved to require more robust systems that prioritize safety. A modern upgrade ensures your home meets current AS/NZS 3000 standards and avoids issues with insurance or council approvals during renovations.

Common Questions We Get About Wiring Upgrades
Do I have to rewire my entire home?
Not always. In some cases, only certain circuits need upgrading—especially if your switchboard is modern. Our electricians will recommend what’s necessary and what can be left alone.
How long does a full rewire take?
For an average 3-bedroom home, a full rewire can take 5 to 10 days, depending on accessibility and the condition of the existing system.
Is it messy or disruptive?
We take care to minimise disruption, using careful wall access techniques and cleaning up each day. For major jobs, we’ll discuss staging the work so you’re not without power for extended periods.
