After a storm or flood, you should never turn your power back on until a licensed electrician has completed a full electrical safety check of your switchboard, wiring and appliances. Water and storm damage create hidden hazards, including short circuits, insulation breakdown and corrosion that can cause electric shock or fire, even after everything looks dry.
T42 Electrical helps Gold Coast homeowners and businesses with post-storm electrical safety checks, emergency call-outs and safe power reconnection every storm season. If severe weather has hit your property, here’s what you need to know.
Why Storms and Floods Create Hidden Electrical Hazards
Most people focus on visible damage after severe weather: broken fences, fallen branches, water through the ceiling. But some of the most dangerous problems are invisible. Water that reaches your switchboard, soaks into wall cavities or pools around powerpoints creates electrical hazards that persist long after the skies clear.
Floodwater isn’t clean, either. On the Gold Coast, stormwater runoff carries sediment, garden chemicals, sewage and salt. These contaminants accelerate corrosion on wiring, degrade cable insulation and leave conductive residue inside switchboards and outlets. Even brief contact with contaminated water can compromise your home’s electrical system for weeks or months after the event.
What Storm and Flood Damage Does to Your Electrics
Understanding the specific risks helps you make better decisions in the hours after a weather event. Here’s what actually happens inside your walls, switchboard and appliances when water gets in.
Switchboard Damage
Moisture bridges connections between live components, causing short circuits and tripping safety switches. Mud left behind by receding water stays conductive, so the hazard persists even after things look dry. A submerged switchboard typically needs components replaced, not just dried out.
Wiring Insulation Breakdown
Cables inside your walls rely on plastic insulation to contain current. Prolonged exposure to contaminated floodwater breaks that insulation down. The immediate risk is a short circuit or shock, while the longer-term risk is gradual corrosion that creates fire hazards weeks or months later.
Water in Outlets and Light Fittings
In a flood, water rises directly into outlets near the floor. During storms with roof damage, rain tracks down wall cavities and pools inside ceiling fixtures. Either scenario creates a live hazard that isn’t always visible. Homes in low-lying suburbs like Coomera, Pimpama and Southport are especially vulnerable.
Solar PV System Risks
Your solar panels generate electricity whenever the sun is out, regardless of whether your main power is off. After a storm, damaged panels, inverters or cabling create shock and fire risks on your roof. The Queensland Electrical Safety Office is clear on this: do not attempt to turn off or inspect a damaged solar system yourself. Have a licensed electrician recommission the system before any rooftop clean-up begins.
Immediate Steps After a Storm or Flood
When severe weather has passed, the first few decisions matter enormously. Work through these in order.
- Turn off the power at the switchboard, but only if it’s safe to reach. If you’d need to stand in water, or the board shows signs of water damage, scorching or arcing, don’t touch it. Call a licensed emergency electrician.
- Unplug all appliances and switch off powerpoints. Do this before the power comes back on. Wet appliances short-circuit the moment current flows through them, including hard-wired units like air conditioners and ovens.
- Stay well clear of fallen powerlines. In the November 2025 SEQ storms, more than 900 powerlines came down alongside 880,000 lightning strikes. Treat every fallen line as live, stay at least eight metres away, and call Triple Zero (000).
- Don’t use water-damaged equipment. Kettles, toasters, televisions, chargers. If it’s been wet, don’t plug it in. Contaminated floodwater leaves residue inside appliances that causes shock or fire even after drying.
- Document everything for insurance. Photograph affected areas before cleaning. This includes your switchboard, outlets, appliances and visible water marks on walls.
When You Need a Professional Electrical Safety Check
Not every storm requires a full inspection. A brief power outage during a thunderstorm is very different from floodwater entering your home. Here’s how to judge.
- Floodwater entered your property. Any water reaching your switchboard, outlets or wiring requires a full electrical safety check before reconnection. Energex may have disconnected your supply and left an Electricity Defect Report in your meter box. A licensed electrician must complete the check, fix defects and sign the report before power is restored.
- Your switchboard has been wet or damaged. Scorch marks, a burning smell, tripped breakers that won’t reset, or visible moisture around the board all need immediate professional attention.
- Lightning struck nearby. A close strike can damage wiring and surge through circuits. Properties along the Gold Coast hinterland from Mudgeeraba through to Springbrook sit in one of the most lightning-active corridors in South East Queensland.
- You notice warning signs. Flickering lights, buzzing from outlets, a burning smell, warm or discoloured wall plates, or safety switches tripping repeatedly all signal hidden damage.
- Your home is older than 20 years. Even without obvious damage, a post-storm check is wise for older properties across Carrara, Nerang and Ashmore. Original switchboards with ceramic fuses instead of modern RCDs are far less resilient to storm stress.
What Happens During a Post-Storm Electrical Safety Check
A proper inspection is thorough and methodical. It’s not a quick visual once-over.
Switchboard Assessment
Testing all circuit breakers, safety switches and RCDs for correct operation. Checking for moisture, corrosion, debris and signs of arcing. Verifying that protective devices trip at the correct thresholds.
Wiring Integrity Testing
Using insulation resistance testing equipment to check whether cables remain safe. This detects damage hidden inside walls and ceiling spaces, which is critical in homes where floodwater has soaked wall cavities.
Outlet and Fitting Inspection
Testing every power outlet and light fitting in affected areas for earth faults, moisture and correct polarity. Replacing any components showing water damage or corrosion.
Appliance Safety Checks
Hard-wired appliances like air conditioners, ovens and hot water systems are tested for insulation resistance and earth continuity. Portable items that were submerged are generally condemned, as contaminated water causes internal damage that makes them unreliable.
Reconnection Certification
Once testing is complete and defects repaired, the electrician issues a Certificate of Testing and Compliance under the Electrical Safety Regulation 2013. This confirms your property is safe and allows Energex to reconnect your supply.
Why the Gold Coast Faces Higher Storm and Flood Risk
Living on the Gold Coast means severe weather is part of the deal. Understanding the scale helps explain why electrical safety checks after storms aren’t something to skip.
Queensland’s storm season runs November through March, and the Gold Coast sits squarely in the path. The November 2025 supercell storms produced 58,000 lightning strikes over the Gold Coast, Scenic Rim and Logan corridor alone. More than 162,000 Energex customers lost power and 900-plus powerlines came down.
Ex-Tropical Cyclone Alfred in March 2025 hit even harder. The Gold Coast received 400 to 600mm of rainfall over several days, with wind gusts above 100km/h bringing down trees and powerlines across Mudgeeraba, Labrador and the wider region. At peak, 450,000 homes and businesses lost power. Fallen trees at Mudgeeraba sparked an electrical fire, and the Molendinar substation experienced faults during the event.
Flooding compounds the problem. The Nerang River catchment covers 400 square kilometres, with major flood events recorded in 1974, 2013, 2017 and 2022. Mudgeeraba Creek is specifically prone to flash flooding. Northern suburbs including Coomera, Pimpama and Ormeau sit within the Coomera River flood zone and experienced significant inundation during the 2022 La Nina event.
Salt air corrosion adds another layer for coastal properties. Homes in Palm Beach, Burleigh Heads, Currumbin and Mermaid Waters face accelerated deterioration of electrical connections and external wiring. After a storm, existing corrosion combines with moisture to create serious fault conditions.
How to Protect Your Electrical System Before the Next Storm
Prevention won’t stop a cyclone, but it significantly reduces the damage.
- Install whole-home surge protection. A surge protector at the switchboard shields your system from lightning-induced voltage spikes. It’s one of the best investments for Gold Coast properties, especially along the hinterland from Pacific Pines to Springbrook where lightning activity is heaviest.
- Upgrade your switchboard. If your home still has ceramic fuses or a board without RCDs, a switchboard upgrade brings protection up to current Australian Standards. Modern circuit breakers and safety switches respond faster to faults and handle storm stress far better.
- Test your safety switches quarterly. The Queensland Electrical Safety Office recommends pressing the test button on your RCDs every three months. If a safety switch doesn’t trip when tested, get it replaced immediately.
- Schedule an annual electrical safety inspection. A routine check picks up degraded connections, corroded terminals and worn insulation before a storm turns them into emergencies. Especially valuable for properties over 25 years old in Nerang, Carrara, Ashmore and Upper Coomera.
- Raise electrical equipment in flood-prone areas. If your property sits within a flood overlay zone, consider relocating outlets, the switchboard and hard-wired appliances above expected flood levels. A worthwhile investment for homes in low-lying parts of Southport, Coomera and along the Nerang River corridor.

Frequently Asked Questions
Do I need an electrician after every storm?
Not necessarily. A brief power outage with no water entry and no warning signs usually doesn’t require an inspection. But if floodwater reached any part of your electrical system, lightning struck nearby, or you notice flickering lights or tripping safety switches, a professional electrical safety check is essential.
Can I turn the power back on myself after a flood?
No. In Queensland, Energex may have disconnected your supply and left an Electricity Defect Report in your meter box. A licensed electrician must inspect your switchboard, wiring and appliances, fix any defects, and sign that report before reconnection can proceed.
How long does a post-storm electrical safety check take?
A straightforward inspection typically takes one to two hours. Properties with significant flooding may need half a day or more, especially if the switchboard, wall wiring and multiple appliances all require testing.
Will my insurance cover the electrical safety check?
Most home insurance policies cover storm and flood damage, including electrical inspections needed for reconnection. Document all damage with photos before any clean-up begins. Your electrician’s Certificate of Testing and Compliance serves as supporting documentation for your claim.
Is it safe to use appliances that got wet but still work?
No. Contaminated floodwater leaves conductive residue on internal components that can cause shock or fire over time, even if the appliance seems fine. Have a licensed electrician test any water-affected appliance, and replace items that were fully submerged.
What should I do about my solar panels after a storm?
Don’t touch, inspect or try to isolate your solar PV system yourself. Panels generate electricity whenever sunlight hits them, regardless of whether your main power is on. Stay clear of all panels, inverters and wiring, and have a licensed electrician inspect and recommission the system before any rooftop work begins.
