What Affects the Cost of Electrical Fault Finding?

Several factors influence what you’ll pay for fault finding:

1. Type of Fault

Some faults are straightforward — a loose connection, a blown fuse, a faulty appliance. Others are more complex — intermittent faults that come and go, earth leakage issues, or problems hidden inside walls. The more complex the fault, the longer it takes to find and fix.

2. Location of the Fault

If the fault is easily accessible (like a power point or light switch), it’s quick to diagnose. If it’s hidden inside a wall, under the house, or in the roof cavity, it takes more time. Cost adds $100–$300 for hard-to-reach faults.

3. Age of Your Wiring

Older homes (pre-1990) often have degraded wiring, corroded connections, or outdated switchboards. These faults take longer to diagnose because there are more potential failure points. Cost adds $100–$200.

4. Number of Circuits Affected

If the fault affects one circuit, it’s usually quick to find. If it affects multiple circuits or the whole house, we need to check more components. Cost adds $50–$150 per additional circuit.

5. Testing Equipment Required

Some faults require specialised testing equipment like insulation resistance testers, earth loop impedance testers, or thermal imaging cameras. We include the cost of testing in our hourly rate, so there are no extra charges.

6. Repairs Required

Fault finding is one thing — fixing the fault is another. If we need to replace wiring, install new power points, or upgrade your switchboard, those costs are separate. We’ll give you a quote before doing any repairs.

Signs You Have an Electrical Fault

Most electrical faults don’t announce themselves with a bang. They creep in gradually — a breaker that trips a bit more often, a light that flickers when the wind blows, a power point that feels warm to the touch. Here are the warning signs that tell you something’s wrong:

Warning Signs Inside Your Home

• Circuit breakers tripping regularly — once in a while is normal. Every week? That’s a fault.
• Safety switches tripping — especially after rain or when specific appliances turn on
• Flickering or dimming lights — particularly when other appliances kick in (like the air conditioner)
• Burning smells — from power points, light switches, or the switchboard. Never ignore this.
• Buzzing or crackling sounds — from switches, power points, or the switchboard
• Warm or discoloured power points — brown marks around a power point mean arcing has been happening
• Power points that don’t work — especially in specific rooms or on one side of the house
• Light switches that feel hot — switches should never be warm to the touch

Warning Signs Outside Your Home

• Flickering outdoor lights — could be a weatherproof power point letting in moisture
• Power outages on one side of the house — could be a mains supply issue or a tripped main switch
• Unusually high electricity bills — a hidden fault (like earth leakage) can waste power without you noticing

If you’re seeing any of these signs, don’t wait. Small faults become big problems fast — and big problems cost more to fix. Call a licensed electrician straight away.

Real Examples: Electrical Fault Finding Jobs We’ve Done in the Redlands

Here are some real jobs we’ve completed across Brisbane and the Redlands, with actual costs:

Example 1: Circuit Breaker Tripping in Capalaba

The fault: Customer’s circuit breaker kept tripping every few hours. They’d reset it, and it would trip again.

What we found: A faulty dishwasher was causing earth leakage. The safety switch was doing its job — cutting power to prevent electric shock.

The fix: We told the customer to replace the dishwasher. We tested the circuit to confirm it was working correctly after the faulty appliance was removed.

The cost:

• Labour: 1 hour @ $150/hour = $150
• Total: $150 (plus the cost of a new dishwasher)

Example 2: Burning Smell from Switchboard in Cleveland

The fault: Customer smelled burning coming from their switchboard. They turned off the power and called us immediately.

What we found: A loose connection on one of the circuit breakers was causing arcing and overheating. The insulation around the wire was starting to melt.

The fix: We replaced the damaged circuit breaker and repaired the wiring. We also checked all other connections in the switchboard to make sure they were tight.

The cost:

• Labour: 2 hours @ $150/hour = $300
• New circuit breaker: $80
• Total: $380

Example 3: Intermittent Power Loss in Alexandra Hills

The fault: Customer’s power would go out randomly, then come back on. It was happening 2–3 times a week, usually in the evening.

What we found: A corroded connection in the meter box was causing intermittent power loss. The corrosion had built up over years, and the connection was finally failing.

The fix: We cleaned the corroded connection and tightened it. We also checked all other connections in the meter box to make sure they were secure.

The cost:

• Labour: 1.5 hours @ $150/hour = $225
• Total: $225

Example 4: Flickering Lights Throughout House in Thornlands

The fault: Customer’s lights were flickering throughout the house. It was getting worse over time.

What we found: A loose neutral connection in the switchboard was causing voltage fluctuations. This is a serious fault — it can damage appliances and cause fires.

The fix: We tightened the loose neutral connection and checked all other connections in the switchboard. We also tested the voltage at several power points to confirm it was stable.

The cost:

• Labour: 2 hours @ $150/hour = $300
• Total: $300

Example 5: Safety Switch Tripping in Victoria Point

The fault: Customer’s safety switch kept tripping, especially after rain. They’d reset it, and it would trip again a few hours later.

What we found: Water was getting into an outdoor power point, causing earth leakage. The safety switch was doing its job — cutting power to prevent electric shock.

The fix: We replaced the outdoor power point with a weatherproof IP-rated model and sealed the surrounding area to prevent water ingress. We also checked all other outdoor power points to make sure they were weatherproof.

The cost:

• Labour: 2 hours @ $150/hour = $300
• New weatherproof power point: $85
• Total: $385

How Long Does Electrical Fault Finding Take?

Most fault finding jobs are completed in 1–3 hours:

• Simple faults (loose connection, blown fuse): 30–60 minutes
• Medium faults (circuit breaker tripping, power point not working): 1–2 hours
• Complex faults (intermittent, earth leakage): 2–4 hours

Important: Fault finding can take longer than expected if the fault is hard to locate. We’ll keep you updated throughout the job and let you know if it’s going to take longer than quoted.

What Happens During a Fault Finding Visit?

Not sure what to expect when you call us out? Here’s how a typical fault finding visit works from start to finish:

Step 1: Your Description

We start by asking you what’s happening — when did it start, how often does it happen, and what triggers it. The more detail you can give us, the faster we can narrow it down. “The breaker trips when the kettle turns on” is much more useful than “the power keeps going off.”

Step 2: Visual Inspection

We inspect your switchboard, power points, and light switches for obvious signs of damage — burn marks, loose connections, corrosion, or melted insulation. This takes 10–15 minutes and often reveals the problem straight away.

Step 3: Circuit Testing

We use specialised testing equipment to check each circuit: insulation resistance testers to find damaged wiring, earth loop impedance testers to check your earthing, and multimeters to verify voltages. This is where we find hidden faults — the ones you can’t see or smell.

Step 4: Fault Isolation

Once we’ve identified the faulty circuit, we isolate it and test individual components — power points, light switches, appliances — until we find the exact cause. For intermittent faults, this is the step that takes the longest.

Step 5: Repair and Testing

Once we’ve found the fault, we fix it — tighten the connection, replace the power point, repair the wiring, or whatever’s needed. Then we re-test the circuit to confirm it’s working correctly and safely.

Step 6: Compliance Certificate

After the repair, we issue a Queensland Electrical Safety Certificate. This is your proof that the work was done by a licensed electrician and meets Australian Standards. You should receive this within 30 days of the work being completed.

Can I Find and Fix Electrical Faults Myself?

No. Queensland law requires a licensed electrician for all electrical fault finding and repairs. DIY electrical work is illegal and can:

• Void your home insurance — if there’s a fire caused by unlicensed work, your insurer won’t pay out
• Be dangerous — you risk electric shock, fire, or death
• Fail inspection — if you sell your home, unlicensed work will be flagged in the building inspection
• Cost more to fix — we often get called out to fix DIY electrical work, and it costs more to undo and redo it properly

What you CAN do safely:

• Check if a circuit breaker has tripped and reset it (once)
• Check if a safety switch has tripped and reset it (once)
• Unplug faulty appliances (including ceiling fans if they’re causing issues — see our ceiling fan replacement cost guide)
• Turn off the power at the switchboard if you smell burning or see sparking

Anything else — call a licensed electrician. It’s not worth the risk.

When to Call an Electrician Immediately

Some electrical faults are emergencies. Call us immediately if you notice:

• Burning smell from power points or switchboard — could be a fire hazard
• Sparking from power points or switches — could be a loose connection or short circuit
• Hot power points or switches — could be an overloaded circuit or loose connection
• Buzzing or crackling sounds from switchboard — could be arcing or a failing circuit breaker
• Visible damage to wiring or power points — could be exposed live wires
• Water damage to electrical equipment — could cause electric shock

In an emergency: Turn off the power at the main switch and call us on 0419 014 146. We offer same-day emergency service across the Redlands.

How to Prevent Electrical Faults

Here’s how to reduce the risk of electrical faults in your home:

1. Don’t Overload Power Points

This is especially important if you’re charging an EV at home — check our EV charger installation cost guide for safe charging practices.

Don’t plug too many appliances into one power point or power board. Overloading can cause overheating and fires. Use power boards with built-in surge protection.

2. Check Appliances Regularly

Look for frayed cords, damaged plugs, or cracked casings. Replace damaged appliances immediately. Don’t try to repair them yourself — call a licensed electrician.

3. Test Safety Switches Every 3 Months

Press the test button on your safety switches every 3 months. If they don’t trip, call a licensed electrician to replace them. Safety switches can save your life — make sure they’re working. Learn more from Electrical Safety Queensland.

4. Get Your Switchboard Checked Every 10 Years

Have a licensed electrician inspect your switchboard every 10 years. If it needs upgrading, check our switchboard upgrade cost guide for pricing. They’ll check for loose connections, corrosion, and other issues that could cause faults.

5. Use Licensed Electricians for All Work

Always use a licensed electrician for electrical work. DIY electrical work is illegal and dangerous. A licensed electrician will do the job safely and provide a compliance certificate. Learn more about QLD electrical licensing requirements.

Fault Finding in Older Redlands Homes

If you live in an older home across the Redlands — a 1970s brick veneer in Cleveland, a 1980s fibro cottage in Wellington Point, or a pre-1990s home in Capalaba — your wiring is more likely to develop faults. Here’s why:

• Degraded insulation — wiring insulation from the 1970s and 80s becomes brittle over time, leading to short circuits and earth faults
• Corroded connections — Brisbane’s humidity accelerates corrosion in meter boxes and switchboards, especially in bayside suburbs like Manly and Wynnum
• Outdated switchboards — older fuse boxes and early circuit breaker panels weren’t designed for modern electrical loads (air conditioners, EV chargers, heat pumps)
• Missing safety switches — homes built before 1991 may not have safety switches on all circuits, meaning faults can go undetected
• Aluminium wiring — some 1970s homes have aluminium wiring, which is more prone to loose connections and overheating

If your home was built before 1990, we recommend a full electrical inspection every 5 years. It’s cheaper than dealing with a major fault — and it gives you peace of mind that your family is safe. Read our guide on switchboard upgrade costs if your panel is showing its age.
