Frequently Asked Questions

What is electrical fault finding?
Electrical fault finding is the process of identifying and diagnosing issues within an electrical system. This involves testing circuits, inspecting wiring, and using specialised tools to locate faults such as short circuits, overloaded circuits, or damaged components. Once the fault is identified, your electrician will recommend the necessary repairs to restore safety and functionality.
Can electrical faults be dangerous?
Yes, electrical faults can be extremely dangerous. Faulty wiring, overloaded circuits, or damaged appliances can lead to electrical shocks, fires, or even fatal accidents. Common risks include exposed wires, flickering lights, burning smells, or tripping circuits. If you notice any of these signs, it’s crucial to contact a qualified electrician immediately to diagnose and resolve the issue safely.
How long does electrical fault finding take?
The time required for electrical fault finding depends on the complexity of the issue. Simple faults, such as a tripped circuit, can be identified and resolved within 30 minutes to an hour. More complex issues, such as hidden wiring faults or intermittent problems, may take several hours or require multiple visits. Your electrician will provide a clear diagnosis and timeline once the fault is located.
What are the signs of an electrical fault?
Common signs of an electrical fault include:
  • Flickering or dimming lights
  • Frequent tripping of circuit breakers
  • Burning smells or scorch marks near sockets or switches
  • Buzzing or crackling sounds from electrical outlets
  • Hot or discoloured sockets
  • Mild electric shocks when touching appliances
If you notice any of these signs, turn off the power at the consumer unit and contact a qualified electrician immediately.
Will the fault be repaired during the same visit?
Wherever possible, our electricians will repair the fault during the same visit, provided the necessary parts are available. If specialist components or further testing are required, we will temporarily secure the system and schedule a follow-up visit at your convenience. You’ll receive a detailed explanation of the work needed and a fixed-price quote before any additional repairs.
