Fast and reliable electrical fault diagnosis – fixed safely by qualified professionals

Electrical Fault Finding

When an electrical fault occurs, it’s not just inconvenient, it can be dangerous. Whether you’re a homeowner, landlord, or business owner, you need a qualified electrician who can quickly identify and resolve the issue safely.

At NPM Electrical, we provide expert electrical fault finding and diagnostics for both domestic and commercial properties across Sussex, Surrey and Kent. From tripping switches and flickering lights to faulty sockets or unexplained power loss, our NICEIC-approved electricians will pinpoint the problem and fix it efficiently.

With years of experience and the latest testing equipment, we can trace faults, repair issues, and restore your system to full working order, often on the same visit.

Common Electrical Faults

Electrical faults can develop gradually or appear suddenly, but ignoring them can lead to serious problems. Electrical fires, shocks, or damage to appliances for example. If you notice unusual electrical behaviour, it’s always best to have it checked by a professional.

Some of the most common electrical issues we encounter include:

Tripping switches, RCDs or blown fuses
Overloaded circuits causing repeated power loss
Damaged sockets and light switches
Faulty wiring or poor connections
Short circuits and power surges
Grounding or earthing issues
Buzzing, humming, or burning smells from outlets
Lighting faults such as flickering or dead circuits
Degraded insulation or corroded connections
Poorly installed or old electrical systems

Whatever the cause, NPM Electrical can diagnose it quickly. In most cases, we can carry out the necessary repairs immediately, restoring safety and functionality on the same day.
