What happens on the day
Fault diagnosis follows an orderly sequence of checks to find the problem safely and minimise disruption to your home or commercial premises.
- Gathering fault detailsWe begin by reviewing the symptoms, including when the problem started, which appliances were running, and which breakers have tripped. Knowing the pattern speeds up the physical testing process.
- Circuit isolation and instrument testingThe affected section is isolated safely. Using specialised test meters, we measure insulation resistance, earth continuity, and circuit loops to trace the fault directly to a specific cable, accessory, or component.
- Immediate correction or written quotationWhere the fault involves a damaged socket, switch, breaker, or accessible connection, repairs are carried out during the visit using carried stock. If more extensive work is required, a clear written price is given.

WhatsAppWhat should I do if a circuit breaker keeps tripping?
Unplug all appliances connected to that circuit and attempt to reset the breaker at the consumer unit. If it resets successfully, reconnect appliances one by one to see which one causes the trip. If the breaker trips immediately with nothing connected, leave it off and arrange for diagnostic testing.
Can most electrical faults be repaired on the same visit?
Routine issues such as failed circuit breakers, burnt socket outlets, damaged light switches, or loose junction connections can typically be fixed during the initial visit using standard components carried in stock. If extensive cable replacement or specialized parts are required, we secure the circuit and quote for the remaining work.
What causes a burning smell near sockets or switches?
A burning smell or discolouration indicates an electrical connection has become loose or overloaded, generating excessive heat that scorches the plastic and insulation. You should immediately turn off the relevant circuit at the consumer unit and keep it switched off until it has been inspected and tested.
Why does an RCD trip even when individual breakers are off?
An RCD detects current leaking to earth from either line or neutral conductors. Even when a single-pole circuit breaker is switched off, the neutral wire remains connected to the consumer unit neutral bar. A neutral-to-earth fault anywhere on the shared circuits can still cause the RCD to trip.
What happens if the fault is inside an appliance rather than the wiring?
Testing identifies whether the fault sits within the permanent building wiring or inside a plugged-in appliance. If an appliance is responsible, we will show you which item failed the test so you can have the appliance repaired or replaced without changing your fixed wiring.
