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 If your earthing is damaged, missing, or outdated, you could be at serious risk without even knowing it.

Why check your earthing?

Over time, earth connections can corrode, break, or loosen. In older homes especially, earthing systems might not meet modern standards — or may have never been installed properly in the first place. Without a solid earth connection, safety switches (RCDs) may not trip fast enough during a fault, increasing the risk of electric shock or fire.

Getting your earthing checked means:

  • Your home is safer for you and your family
  • RCDs and circuit breakers function as they should
  • Fault currents are carried away from metal surfaces
  • Your appliances are better protected from surges
  • You comply with current NZ electrical safety regulations

When should you have your earthing checked?

You should definitely consider an earthing check if:

  • Your home is more than 20 years old and hasn’t been inspected
  • You’re planning to install a new switchboard or RCDs
  • You’ve experienced shocks from taps or appliances
  • You’re noticing flickering lights or tripping breakers
  • You’ve recently had major plumbing or electrical work done

Even if everything appears to be working fine, a compromised earth might not show itself until there’s a serious fault.

My approach

I carry out a full inspection of your home’s earthing system — from the earth stake to the main switchboard and water pipe bonding. I’ll check for proper connections, measure earth resistance, and make sure your system is compliant, safe, and ready to handle fault conditions. If there’s an issue, I’ll explain clearly what’s wrong and what’s needed to put it right.

What to expect

An earthing check usually includes:

Inspecting the main earth connection and conductor

  • Testing the earth stake (if present) for resistance and continuity
  • Verifying bonding to metal pipework and other services
  • Checking all terminations at the switchboard
  • Replacing or upgrading earth stakes or conductors if needed

If your earthing system isn’t up to standard, I’ll provide a clear plan to bring it up to scratch — with no unnecessary extras.

    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.

    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.

    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.
