What happens on the day
A fault finding visit focuses on structured diagnostic testing to isolate the defect, make the installation safe and carry out on-the-spot repairs whenever possible.
- Initial symptoms and information checkWe begin by gathering details on which circuits trip, what appliances were running when the problem started, and which rooms have lost power. Checking consumer unit labelling and looking over the affected points helps narrow the starting point.
- Circuit isolation and instrument testingUsing calibrated test instruments, we isolate the problem circuit and perform insulation resistance, continuity and earth loop impedance tests. This reveals hidden damage inside walls, ceilings and under floors without unnecessary structural disruption.
- Component inspection and testingOnce the fault is pinpointed to a specific run of cable, socket, switch or junction point, we open the accessory to inspect the wiring terminations, check for loose conductors and inspect for overheating or moisture ingress.
- Immediate repair or detailed written quoteWhere the repair requires routine parts such as replacement switches, standard sockets or replacement circuit breakers, the work is carried out during the visit. If extensive rewiring or specialist materials are necessary, we leave the circuit safe and provide a clear written estimate for the remaining work.

What should I check before booking a fault finding visit?
If an RCD or circuit breaker trips, try unplugging all appliances on that circuit and resetting the switch at the consumer unit. If the breaker stays on, plug appliances back in one at a time to check if an appliance is causing the trip. If the breaker trips immediately with nothing plugged in, book a diagnostic visit.
Can most electrical faults be repaired on the same visit?
Yes. Most faults are traced and repaired during the diagnostic visit. We carry replacement sockets, switches, breakers and common circuit components. If the fault stems from extensive cable damage requiring plaster removal or specialist parts, we ensure the circuit is safely isolated and provide a quote for the full repair.
What does the fault finding price cover?
The diagnostic price covers the time and testing equipment needed to locate the source of the electrical failure across the consumer unit and circuit wiring. Minor repairs using carried standard parts are completed within the diagnostic visit, while any required secondary work is quoted separately.
Is a burning smell or warm socket faceplate dangerous?
Yes. A burning smell, buzzing sound or warm switch plate indicates loose terminations or overloaded cables generating excessive heat, which presents a fire risk. Turn off the affected circuit at the fuse board straight away and arrange an electrical inspection.
Why do my outside lights trip the electricity when it rains?
Outdoor lights and external power sockets are prone to weather degradation over time. Even small amounts of rainwater or condensation entering a fitting, junction box or conduit can cause current to leak to earth, immediately tripping the main RCD at your consumer unit.
