Common Electrical Faults We Fix
No matter how small or large the issue might seem, we’re equipped to investigate and resolve all types of electrical faults. Our local electricians work quickly, efficiently, and always with safety in mind.
We regularly identify and fix the following:
- Tripping RCDs or MCBs
- Blown fuses
- Intermittent power loss
- Dead sockets or lighting circuits
- Damaged cables or loose connections
- Overloaded circuits
- Buzzing sounds from consumer units or sockets
- Burning smells or scorched fittings
- Flickering lights
- Partial or full power outages
Some issues, like a faulty appliance or a loose wire, are easy to spot and resolve. Others, like damaged underground cables or hidden faults in older wiring systems, require more in-depth investigation. Either way, we have the tools, experience, and knowledge to trace and fix the problem quickly.
How Our Power Fault Repairs Work
Our electrical diagnostics process is systematic and thorough. We use advanced test equipment and a methodical approach to ensure we don’t just treat the symptoms—we find the real cause of the fault.
Initial Assessment: We’ll ask about the fault, recent changes to your electrics, and when the problem occurs.
Visual Checks: We inspect the consumer unit, sockets, switches, and visible wiring.
Testing & Diagnostics: Using insulation resistance testers, loop testers and voltage testers, we perform live and dead tests to identify faults.
Trace & Locate: We follow the fault through the circuit to pinpoint its location.
Repair or Quotation: If the fault is minor, we’ll usually fix it immediately. For larger issues, we’ll provide a quote for remedial work.
Certification (if Required): We’ll provide full certification for faults linked to larger repairs or rewiring.


Act Fast! Faults Can Lead to Bigger Problems
Electrical faults should never be ignored. What starts as a flicker or an occasional trip can escalate into serious risks such as electric shock, fire, or system-wide failure. That’s why it’s essential to get faults checked and repaired by a qualified electrician as soon as possible.
We’re here to help. If you notice unusual behaviour from your electrical system—such as frequent tripping, hot sockets, or buzzing sounds—give us a call. We’ll inspect, test, and repair as needed so you can get back to normal life without worry.
What causes an RCD to trip repeatedly?
This could be a faulty appliance, a damaged cable, water ingress, or a wiring fault. We can test each circuit to locate the issue.
Can I fix an electrical issue myself?
We don’t recommend it. Even small faults can be dangerous. Always call a qualified electrician for diagnosis and repair.
Do you offer emergency electrical services?
Yes, we’re available 24/7 for urgent electrical services that affect safety or power supply.
How much does fault finding cost?
It depends on the time involved and the nature of the fault. We provide clear pricing before any work begins.
What if the fault is linked to an old consumer unit?
We’ll explain your options and may recommend a consumer unit upgrade for safety and compliance. All advice is tailored to your property.
