When might you need electrical fault finding?
Fault finding is the work of locating why a circuit trips, a socket is dead or lights flicker. The cause may be an appliance, moisture, a loose connection or damaged cable. Replacing parts before the cause is known often leaves the fault in place.
Common reasons to request this service
- An RCD or circuit that keeps tripping One reset is reasonable. If it trips again immediately, leave it off and describe what was in use at the time.
- Intermittent faults Flickering, buzzing or a fault that appears only when something is plugged in still needs a proper test, not repeated resets.
What the electrician usually checks
The electrician tests the circuit and the connected equipment, and separates an appliance fault from a fault in the fixed installation. Further investigation is agreed if the first tests do not identify the cause.
What affects the cost
- How long the testing takes
- Whether access to floors, lofts or walls is needed
- Replacement parts
- Any remedial work found during the test
Safety
Call 999 if there is fire, smoke or someone has received a shock and needs urgent help. Do not open a consumer unit or keep resetting a device that trips at once.
Questions
Can I find the faulty appliance myself?
You can unplug appliances and try one reset. If the device trips with everything unplugged, or trips again immediately, stop and ask an electrician.
