Electrical fault finding

Common reasons why your wiring has been damaged

Unfortunately, lightning storms are not your electrical installation’s only enemy. In fact, many British households are more likely to malfunction due to worn or torn cables, corrosion, overloading circuits, accidental damage (putting nails through wiring), or by environmental hazards, such as burst pipes. The qualified electrical professionals at Plumbery will help you deal with various electrical faults then & there. Here’s what makes us a good pick:

Getting to the actual cause of a fault

Tripping breakers, flickering lights, or sockets that stop working are symptoms of an underlying fault, not the fault itself. Our electricians use proper test equipment to trace the problem back to its source, whether that’s a damaged cable, a failed connection, overloading, or a fault in an appliance, rather than simply resetting the circuit and hoping it holds.

Every fault-finding visit includes earth and bonding checks where relevant, a clear explanation of what was found, and a fixed-time quote for the repair. Qualified, insured electricians are available across London within the M25.

How can you tell if you need a pro?

Symptoms usually include flickering lights, the burning smell of overheating cables or melting switches, and power outages. You should also keep an eye out for old-fashioned power sockets and switches, hear a crackling noise when you press switches, or if a fuse spontaneously blows out.

Electrical safety checks done the proper way

Fixing errors in high voltage systems requires rigorous preparations. We always make sure to do the following:

  • We analyse the issue that our client has reported and determine why it popped up.
  • We get down to the root of the trouble – bad wiring, a melted switch – we will troubleshoot the whole circuit.
  • We diligently document every possible power or other sources that have caused the issue.
  • We perform various tests and repairs to confirm that our suspicions are true.

Put an end to random short circuits today

For your peace of mind, each professional that knocks on your door is also covered by an insurance plan of up to 5 million GBP. Whatever the task at hand, they will work hard to make your home safer than ever before.
