Electrical fault finding

No power, a circuit that keeps tripping or a switch getting warm. We measure circuit by circuit until the cause is found and repair it in the same appointment.

Electrical fault finding: how we work

How we trace a fault

We switch off circuit by circuit and measure the insulation resistance, so we first pin down the circuit and then the appliance. That is systematic work; guessing costs you more time and money than measuring.

The common causes

A damp outdoor circuit after rain, a failing water heater or dishwasher, a cable chafed through behind a skirting board, or a light fitting that has taken in water. In older installations, perished wiring insulation is a familiar one.

Warm fittings are a signal

If a switch, plug or breaker gets warm, do not wait. It is usually a loose connection, and that produces heat locally. This is one of the few things we say to call about today rather than next week.

What you can do first

Switch off all the circuits, reset the residual current device, then switch the circuits back on one by one. If it trips on a particular circuit, you know where it sits. Call us with that information and we are finished sooner.

Send us your situation with a few photos and you will have a clear quote with a fixed price within 24 hours.

Frequently asked questions about electrical fault finding

Question not answered here? Call or message us and we will think it through with you, free of charge.

How soon can you come?

For a fault we try to come the same day in our core region. Beyond that we schedule as soon as we can. Calling is faster than emailing.

What does fault finding cost?

We charge a fixed fee for tracing the fault, so you know in advance where you stand. If materials are needed, you hear what they cost first.

Do you work outside office hours?

For emergencies, yes. We are available on working days from 08:30 to 17:00, and outside those hours for a genuine fault.

I have no power at all, what now?

First check whether the neighbours are also without power; then it is the grid operator. If only your home is affected, call us.
