Electrical Fault Finding
& Repairs

First, unplug all appliances on the affected circuit and try resetting the RCD. If it holds, plug appliances back in one at a time to identify the faulty one. If the RCD trips with nothing plugged in, or trips again quickly after being reset, there’s a wiring fault that needs proper diagnosis. Call us — do not keep resetting it and ignoring the problem, as the RCD is protecting you.

An RCD trips when it detects a current imbalance — usually caused by a faulty appliance, deteriorating cable insulation, a wiring fault, or moisture getting into a circuit or fitting. Identifying the exact cause requires testing with specialist equipment. We carry out insulation resistance testing and earth fault loop impedance testing to find the source properly.

Fault finding starts from £100 call-out. The total cost depends on how long it takes to locate and repair the fault. We’ll give you a clear indication of likely cost before we start, and provide a written quote for any repair work before proceeding.

It depends on the fault. A burning smell, scorching, sparking or complete loss of power are signs you should treat seriously. If in any doubt, switch off at the consumer unit and call us immediately. For minor faults like a single dead socket, it’s generally safe to wait for a proper repair — but don’t use the affected socket or circuit.

A burning smell from a socket, switch or the consumer unit is a potential fire risk. Stop using that socket or switch immediately. If the smell is strong or you see scorching or discolouration, switch off the relevant circuit at the consumer unit. Call us as a matter of urgency — this is not something to leave.

Flickering lights are most commonly caused by a loose connection — in the light fitting, switch, junction box or wiring. Occasionally it can indicate a more significant wiring issue. If flickering is accompanied by a burning smell or buzzing sound, treat it as urgent. Isolated flickering from one fitting is usually a straightforward repair.

Check your consumer unit first — a tripped circuit breaker or RCD is the most common cause. If everything looks normal at the board, the fault may be a break in the circuit wiring, a failed connection, or a supply issue. If your neighbours are also affected, contact your electricity supplier. If it’s just your property, call us.

Intermittent faults are diagnosed using specialist test equipment — insulation resistance testing, loop impedance testing and thermal imaging where appropriate. We inspect wiring, connections, fittings and the consumer unit systematically to find the cause. Intermittent faults take longer, but we find the root cause rather than guessing.
