What is electrical fault finding?
Electrical fault finding is the process of systematically diagnosing an electrical installation to locate the source of a problem. Unlike a straightforward repair - where the fault is already visible or obvious - fault finding is required when the cause of an issue isn't immediately apparent.
Intermittent faults, unexplained power loss, circuits that trip without obvious reason, and appliances that stop working despite appearing undamaged all typically require a methodical diagnostic approach to resolve properly. Our electricians use professional testing equipment - including insulation resistance testers, loop impedance testers, and RCD testers - to trace faults quickly and accurately, even in complex or older installations.
Common Fault Finding Issues
Tripped Circuits
One of the most common fault finding callouts we receive. If your RCD or breaker keeps tripping - particularly when no specific appliance seems to be causing it - there's an underlying fault on the circuit that needs locating. We test circuit by circuit to isolate the problem and carry out the repair.
Faulty Wiring
Damaged, incorrectly installed, or deteriorating wiring can cause a wide range of symptoms, from flickering lights and partial power loss to burning smells and tripping breakers. Locating a wiring fault within a wall or under a floor requires specialist equipment and experience - exactly what our team brings to every job.
Intermittent Power Loss
Lights or sockets that work sometimes but not others, appliances that cut out unexpectedly, or circuits that fail under load are all signs of an intermittent fault. These can be caused by loose connections, deteriorating cable insulation, or a failing component — and they tend to worsen over time if not addressed.
Burning Smells or Warm Sockets
A burning smell from a socket, switch, or consumer unit, or outlets that feel warm to the touch, indicate a potentially dangerous fault that needs urgent investigation. Our electricians carry out a thorough diagnostic to locate and resolve the source before it becomes a serious risk.
