Keeping your home electrically safe and future-ready is more than just a nice-to-have. Rewiring can be critical for your home. Over time wiring can degrade, your modern electrical load can increase, and standards can change. In this guide we’ll explore when rewiring may be needed, what signs to watch for, what factors affect timing, the benefits of acting, and how OnePoint can help with home rewiring and connected services.
In this guide, we’ll cover how often rewiring is needed, what to look out for, and why calling a licensed electrician from OnePoint is the best move for your home.

How Often Should a Home Be Rewired?
There’s no one-size-fits-all answer, but here’s a practical way to think about it:
- Homes under 20 years old: Usually fine with routine safety checks and switchboard updates.
- Homes 30-50 years old: May need rewiring if the wiring hasn’t been upgraded since construction.
- Homes 50+ years old: Often have outdated materials like cloth or rubber insulation that can become brittle, cracked, or dangerous.
- Homes 40-60 years+ old: The wiring may be original, insulation may be degrading, or homes have been heavily modified are prime candidates for rewiring.
Many electricians suggest checking wiring every 10–15 years, or sooner if you’re planning renovations or notice electrical issues. On renovation forums, homeowners often mention rewiring during a remodel to avoid opening up walls again later.
Major reno or load-increase scenarios (for example adding EV charger, upgrading switchboard, converting living space) are ideal times to consider rewiring. Since you’re already opening walls, the risk and cost of disruption are lower.
Signs Your Home Might Need Rewiring
Here are the most common warning signs that it’s time to call an expert for home rewiring:
- Flickering or dimming lights, particularly when other heavy appliances start up.
- Frequent tripping of circuit breakers or blown fuses even without obvious cause.
- Discoloured outlets or light switches, or a burning smell near socket points.
- Outlets that are hot to touch or show melt marks.
- Old wiring types, e.g., cloth-insulated, aluminium wiring, no earth/ground wire.
- A fuse board or switchboard that lacks modern safety features (RCDs, AFCI, etc).
- Major renovations underway like new rooms, new load, electric vehicle charger, etc.
Placement of a professional condition report can help determine whether a full home rewire is needed or a targeted update will suffice.
Why Rewiring Matters
Rewiring isn’t just about avoiding faults, it’s more about peace of mind and preparing your home for the future. Benefits include:
- Improved safety: Reduces risk of fires, shocks, or electrical failure.
- Better efficiency: Modern wiring handles today’s electrical load safely.
- Compliance: Keeps your home up to current Australian electrical standards.

What Happens if You Ignore Rewiring?
Neglecting outdated or damaged wiring isn’t just an inconvenience but most often a safety concern. A serious safety hazard that can put your family and home at risk. Electrical systems wear out over time, especially in older properties that were never designed to handle the amount of power today’s appliances use.
Here’s what can happen if rewiring is delayed too long:
- Electrical fires or shocks: Worn insulation and frayed wiring can spark without warning, creating fire hazards inside your walls. Faulty wiring also increases the risk of electric shock when using outlets or appliances.
- Damage to connected appliances: Unstable power flow can cause voltage spikes that fry electronics and kitchen appliances. Deteriorating wiring can quickly lead to expensive replacements for damaged devices.
- Frequent power outages or fuse trips: Outdated systems struggle to distribute power evenly, causing constant circuit breaker trips and interruptions. These warning signs indicate your electrical system is overloaded and potentially dangerous.
- Higher electricity bills: Damaged or inefficient wiring forces your system to work harder, wasting power and costing you more each month.
Insurance complications: Many home insurance policies won’t cover fire or property damage caused by proven electrical neglect. If the cause of a fire is traced back to faulty wiring, your claim could be denied.
If you ever notice burning smells, flickering lights, sparking outlets, or sudden power loss, don’t wait! Turn off power at the main switch if it’s safe and call our emergency electrician
right away. OnePoint’s licensed team can inspect your system, make temporary repairs if needed, and plan a safe and permanent fix before serious damage occurs.

Frequently Asked Questions (FAQs)
How often should I rewire my home?
Most experts recommend checking wiring every 10–15 years. Full rewiring is typically needed every 30–50 years depending on materials and maintenance.
Do I need to rewire my entire home?
Not always. OnePoint can assess whether a partial rewire, full rewire, or fault finding repair will be enough.
Will rewiring affect my switchboard?
Often yes. Older boards may not support new wiring safely. Our switchboard upgrades ensure your system runs efficiently.
Is rewiring messy or disruptive?
Our team plans carefully to minimise disruption. We work in stages, clean up daily, and keep you informed throughout the project.
Can I stay in my home during a rewire?
In most cases yes, but for larger projects we might schedule a few short power outages for safety testing.
What if I see sparks or smell burning?
Switch off power at the mains if safe to do so, and call our emergency electrician right away.
