Rewiring a home isn’t cheap. Whether it’s part of a renovation or your electrician flags outdated cabling, the first question is often: Will my insurance cover it? In most cases, no, but it depends on why the rewiring is needed.
Most home insurance policies in Australia cover damage caused by sudden electrical faults. But if your wiring is simply old, unsafe, or no longer up to code, it’s usually seen as your responsibility, not theirs.
This guide breaks down what’s covered, what isn’t, and how to handle the insurance side before you’re stuck paying for everything out of pocket.
What Most Home Insurance Policies Cover
Home insurance is designed to handle the unexpected fires, lightning strikes, and sudden power surges. If your wiring fails in a way that causes visible damage, like a burnt switchboard or scorched wall, your insurer will likely cover the aftermath. But coverage usually stops there.
Insurers don’t pay for the underlying wiring unless the policy specifically includes it. Most draw a hard line: if the damage wasn’t sudden, or if the system was already flagged as outdated, you’re on your own.
So even if an electrical fault starts the chain reaction, it doesn’t guarantee full coverage, especially when old wiring is involved.
When Rewiring Isn’t Covered And Why
Rewiring to replace old, unsafe, or non-compliant cabling is rarely covered under standard home insurance. That includes:
✔ Modernising old wiring
✔ Replacing systems that no longer meet code
✔ Upgrading during renovations
Insurers treat these as maintenance, not emergencies. If the system hadn’t failed yet, or if the issue was known but ignored, you’re expected to handle it without their help.
Even preventative upgrades that reduce long-term risk are outside the scope. Insurance reacts to damage. It doesn’t reward preparation.
The Exceptions: When Rewiring Might Qualify for Coverage
There are rare situations where rewiring can fall under insurance, but it hinges on the cause.
If faulty wiring causes a house fire or major electrical failure, your insurer might approve a claim that includes rewiring as part of the repair. That’s because the damage was sudden and unavoidable.
In other cases, coverage may apply if you’ve added an optional endorsement to your policy, something that explicitly includes electrical systems beyond standard terms. But unless that add-on is in place before the damage, it won’t help you after the fact.
No policy? No payout. No exceptions.
Electrical Standards and Insurance Requirements
Insurers look at more than just what’s broken; they look at how your home measures up to current safety standards. If your wiring doesn’t meet AS/NZS 3000 (the national benchmark), your coverage could be at risk.
Some providers will flat-out reject claims or refuse to renew policies until rewiring is complete. Others may demand an upgrade before offering a quote at all.
A failed electrical inspection doesn’t just mean your wiring’s outdated; it could mean your insurance is hanging by a thread. That’s why licensed compliance matters, even if nothing’s gone wrong yet.
Making an Insurance Claim for Electrical Damage
If your home suffers sudden electrical damage, start by contacting your insurer. Be clear about what happened, when it occurred, and whether emergency work was required.
You’ll need:
✔ A licensed electrician’s report
✔ Photos of the damage
✔ Invoices or receipts for any immediate repairs
The insurer may send an assessor to inspect the property, so having your paperwork ready can speed things up. Missing documents or vague explanations are the fastest way to stall a claim.
Make sure your electrician flags whether the issue was sudden or tied to pre-existing faults; that distinction matters.

Real Costs vs. Assumed Coverage: Know the Gap
Rewiring isn’t a small job. For a two-bedroom home in Sydney, costs usually start around $1,500. Larger properties, or those needing switchboard and socket upgrades, can push well past that.
Many homeowners assume insurance will cover those costs until they read the exclusions. The reality: if your wiring hasn’t already caused damage, your insurer expects you to pay for the upgrade yourself. And if your home fails an electrical inspection, it could impact your policy or stop renewal altogether.
Upfront rewiring costs may sting, but they’re easier to manage than a denied claim or post-incident fire repairs.
What You Should Do Now
Don’t wait for a claim rejection to find out your home’s not up to standard. Check your wiring. Read the fine print. And if you’re unsure what’s covered, ask the right questions before problems hit.
At Olympic Electrical, we help Sydney homeowners stay compliant, safe, and prepared with licensed inspections and insurance-ready documentation.

Frequently Asked Questions
How do I know if my home needs rewiring?
Signs include frequent tripping, discoloured outlets, buzzing sounds, or outdated fuse boxes. A licensed electrician can assess your wiring and confirm if it meets current safety standards.
Can I get insurance after rewiring my home?
Yes. Many insurers are more willing to offer or renew coverage once your home meets AS/NZS 3000 standards. Some may even lower your premium if the upgrade reduces risk.
What happens if I ignore old or unsafe wiring?
Apart from fire and electrocution risks, ignoring outdated wiring can void claims or block future policy renewals. Insurers often treat non-compliance as homeowner negligence.
