NSW is no stranger to wild weather. From thunderstorms and high winds to heavy rain and hail, storms can wreak havoc on your home’s electrical systems. Knowing how to prepare for a storm, spot signs of damage, and respond safely can protect your property and keep your family safe.

In this guide, we explain the most common types of storm-related electrical damage and what you should do before and after a major weather event.

How Storms Affect Electrical Systems

Storms can disrupt or damage your electrical setup in several ways. Fallen power lines, for example, may be caused by trees or debris knocking down overhead cables. Flooding or roof leaks can allow water to seep into switchboards or meter boxes, increasing the risk of short circuits. Power surges from lightning or unstable grid conditions can overload circuits and destroy appliances. Strong winds and vibration may loosen cables attached to private poles or service lines. Some older electrical systems are especially vulnerable if they use outdated components or lack modern weatherproofing, which heightens the chance of long-term safety issues or failures.

Signs of Storm-Related Electrical Damage

After a storm, be alert to flickering lights, burn marks near outlets, sagging or exposed cables, water around your meter box, or safety switches that trip and won’t reset. You might also hear strange buzzing or notice appliances behaving erratically. These signs suggest your system could be compromised. Always stay clear of affected areas and contact a professional — attempting to troubleshoot electrical faults yourself is extremely risky.

How to Prepare Your Home Before a Storm

Effective preparation reduces risk and potential costs. Before storm season begins, inspect your property and address any known electrical vulnerabilities. Secure outdoor furniture and garden equipment so they don’t collide with overhead cables. Trim trees near power lines to minimise the chance of damage from falling branches. Make sure your switchboard is housed in a waterproof enclosure, and test your safety switches to confirm they respond appropriately. If severe weather is forecast, unplug valuable electronics to prevent surge damage and ensure you and your family know how to shut off the power supply in case of emergency.

Having a licensed Level 2 electrician conduct a pre-storm inspection is a proactive way to spot and fix any weaknesses in your electrical system.

What to Do After a Storm

When it’s safe, assess your home from a distance. If your power is out, resist the temptation to reset breakers or touch your meter box — especially if it’s wet. If you see visible damage or notice unusual smells, noises, or performance issues, call a Level 2 ASP immediately. If you plan to lodge an insurance claim, take photos and record the date and time of any storm-related electrical events. Professional repair documentation can help speed up the claims process and reduce disputes with insurers.

Remember, even if your system appears to be working, internal components may have been damaged. A professional inspection is the best way to ensure your home remains safe.

Who to Call for Storm Electrical Damage

Only a Level 2 Accredited Service Provider can legally restore damaged connections between your property and the power network. This includes private power poles, aerial cables, service lines, and metering infrastructure. General electricians are not authorised for this type of high-voltage work.

At Selectrical, we provide 24/7 emergency response across Sydney and surrounding areas. Our team can quickly assess, repair, and certify your setup to meet all NSW safety and compliance requirements. We also liaise with your electricity provider where necessary to streamline the reconnection process.

Why Timely Repairs Matter

Storm damage doesn’t just pose immediate safety risks — it can cause ongoing issues like tripping circuits, electrical fires, or full outages. If damage isn’t repaired promptly, your network provider may issue a defect notice or disconnect supply entirely. Timely intervention:

• Restores power quickly and safely
• Prevents more costly follow-up damage
• Protects your compliance with NSW safety rules
• Preserves the value and insurability of your home

Don’t wait for problems to escalate. Early action saves time, money, and stress.
