Diagnosing Electrical Faults

When something’s not working right, it’s not always obvious what’s causing the problem — that’s where fault diagnosis comes in. Whether it’s flickering lights, tripping breakers, or outlets that suddenly stop working, diagnosing faults is about finding the root cause quickly, safely, and with as little disruption as possible.

Why accurate fault diagnosis matters

Electrical faults can be frustrating — and sometimes dangerous. While some issues are simple (like a blown fuse), others can be symptoms of deeper problems like loose wiring, overloaded circuits, or deteriorated cable joins. Getting the diagnosis right is the first step to a safe and lasting fix.

A professional diagnosis means:

  • You avoid guesswork and unnecessary costs
  • The real issue is identified and resolved at its source
  • You reduce the risk of electrical fires or electric shocks
  • You get clarity on next steps — repair, replace, or leave it be

You prevent recurring problems from wasting time and money

When should you call in a fault diagnosis?

You should get a fault professionally diagnosed if:

  • Lights are flickering, buzzing, or dimming
  • Circuit breakers or RCDs are tripping frequently
  • Power points have stopped working or feel hot to touch
  • You’ve had a sudden loss of power in one area
  • You’ve already tried replacing bulbs or appliances with no result

If you’re unsure, it’s always safer to call — especially if you suspect DIY work or older wiring.

My approach

I start by listening — to you, and to the problem. Then I work methodically to trace the fault using the right tools and experience. I won’t just patch over the issue — I’ll find out what’s really going on and explain it to you. Whether it’s a simple fix or something more involved, you’ll get the full picture and the best solution.

What to expect

When diagnosing a fault, I may:

  • Test individual circuits and isolate affected areas
  • Inspect switchboards, RCDs, fuses, and wiring connections
  • Check for loose wires, damaged fittings, or moisture ingress
  • Use tools like circuit tracers, insulation testers, or thermal imaging (if required)
  • Recommend next steps — from simple repairs to full rewires, if necessary

In most cases, I can either fix the issue on the spot or provide a quote with options.

    Switchboard Upgrades

    When it comes to electrical safety and long-term peace of mind, your switchboard is one of the most important parts of your home. It’s the heart of your electrical system — and if it’s outdated, overloaded, or showing signs of wear, it might be time to consider an upgrade.

    Electrical Home Assessments

    When it comes to keeping your home safe and future-ready, an electrical home assessment is one of the most valuable things you can do. Whether you’re buying, renovating, or simply unsure about the state of your wiring, a professional inspection can give you clarity, peace of mind, and practical next steps — without the guesswork.

    LED Lighting Upgrades

    Lighting plays a big role in your home’s comfort, energy efficiency, and safety — and upgrading to LED is one of the simplest ways to improve all three. Whether you’re replacing old halogens, starting a renovation, or just want to lower your power bill, modern LED lighting offers long-term savings and a better lighting experience.

    SmartVent Installation

    Good ventilation is essential for a healthy, comfortable home — but it’s often one of the most overlooked parts of the house. Whether you’re dealing with condensation, mould, damp air, or stuffy rooms, the right ventilation system can make a big difference to your indoor air quality and overall wellbeing.

    Underground Cable & Mains Checks

    If your home has underground cabling or ageing mains lines, it’s worth checking they’re still safe, stable, and up to standard. Damaged or deteriorating underground cables can lead to power loss, safety issues, or expensive emergency callouts — and in many cases, you won’t know there’s a problem until something goes wrong.

    Power & Lighting Installations

    From extra power points to new light fittings, I handle the day-to-day electrical work that keeps your home running safely and smoothly. Whether you’re refreshing a room, upgrading fixtures, or just need a few changes to make your space more practical, I’m here to help with reliable, professional service.

    Earthing Checks

    A safe home starts with proper earthing — and yet, it’s one of the most overlooked parts of residential electrical safety. Good earthing protects you, your appliances, and your property by safely carrying fault current away when something goes wrong. If your earthing is damaged, missing, or outdated, you could be at serious risk without even knowing it.

    Safety Compliance Checks

    Electrical safety isn’t just about fixing what’s broken — it’s about making sure everything is up to standard, working as it should, and safe for everyday use. Whether you’re planning a renovation, selling your home, or just want peace of mind, a safety compliance check is a smart way to ensure your electrical system is reliable and legal.
