Fault finding & repairs
Find the cause before replacing the wrong thing.
Structured electrical diagnosis for tripping circuits, failed sockets, lighting faults and unexplained problems.
Common symptoms
A breaker or protective device repeatedly switches off.
A socket, light or group of accessories no longer works.
The issue comes and goes or appears under certain conditions.
An accessory shows heat, discolouration, cracking or a burning smell.
External lighting or power has failed or trips in wet conditions.
Something is wrong, but the affected circuit is not obvious.
Diagnostic process
A logical route from symptom to cause.
Fault finding is investigation. The time required depends on whether the problem is present, how the installation is arranged and what previous work has been carried out.
- 01
Gather information
What happened, when it started and what changes or equipment were involved?
- 02
Inspect and isolate
Check visible condition and narrow the issue to an affected item, circuit or section.
- 03
Test methodically
Use appropriate electrical tests to confirm or eliminate possible causes.
- 04
Explain and repair
Discuss the findings, repair options and any further work required.
Stop using anything that is hot, smoking, sparking or visibly damaged.
Do not repeatedly reset a circuit when there is an obvious danger. Isolate the affected item or circuit only if it is safe to do so. For fire or immediate danger, contact the emergency services.
Before the visit
Useful details can shorten the investigation.
Note when the problem occurs and whether it follows rain, appliance use or switching.
List the rooms, sockets, lights or equipment that are affected.
Mention recent building work, new appliances or previous electrical alterations.
Common questions
Fault finding FAQs.
What information should I provide about an electrical fault?
Explain what happened, which circuit or item is affected, whether anything trips, and when the issue started. Photos of the consumer unit can also help.
Should I keep resetting a tripping circuit?
Repeatedly resetting a circuit without understanding the cause is not recommended. Leave the affected circuit off and arrange an assessment, particularly if there is heat, damage or a burning smell.
Can intermittent faults be diagnosed?
Many intermittent faults can be traced through structured inspection and testing, although faults that are not present during a visit can require further monitoring or investigation.
Do you repair sockets and lighting faults?
Yes. Fault finding can cover sockets, switches, lighting circuits, outdoor supplies, tripping circuits and other fixed electrical installation issues.
