Mains & Switchboard Wiring
The heart of a safe, reliable home electrical system
Your switchboard is the control centre of your home’s power. It protects your family, your appliances, and your property by managing circuits safely and responding correctly when faults occur. If the board is outdated, overloaded, or poorly organised, it can lead to nuisance tripping, limited capacity for modern appliances, and increased safety risk.
Our Mains & Switchboard Wiring service covers new installations, upgrades, rewiring, and improvements to protection and capacity — delivered with clean workmanship, compliant testing, and a long-term, future-ready mindset.
What we do
We provide residential mains and switchboard services for new builds, renovations, and existing homes, including:
Switchboard upgrades and replacements
Replacement of older boards with modern switchboards
Improved circuit organisation and clear labelling
Installation of modern protection devices (RCDs/RCBOs as required)
Capacity planning for modern loads and future upgrades
Mains supply wiring and distribution
Main supply wiring upgrades where required
Correct sizing and protection to match the home’s demand
Safe connections and compliant termination practices
Improvements to reliability and stability across circuits
Circuit protection and safety
RCD protection upgrades to improve safety
Fault finding for nuisance tripping and unstable circuits
Repairs and remediation for aged or unsafe wiring
Testing and verification to the required standards
Future-ready planning
If you’re planning upgrades, we can provision the switchboard and circuits for:
EV charging
Heat pumps and high-load appliances
Home office and dedicated equipment circuits
Outdoor power and lighting expansions
Smart home and technology additions (where relevant)
When to consider a switchboard or mains upgrade
You may benefit from an upgrade if:
Your switchboard is older and lacks modern safety protection
You experience frequent tripping or circuits that “max out”
You’re renovating, adding appliances, or increasing demand
You’re adding an EV charger, heat pump, or significant technology loads
The board is untidy, poorly labelled, or difficult to service
You want better safety for your household
Why this work matters
Improved electrical safety
Modern protection devices respond faster and reduce risk in fault conditions.
Better reliability
A well-planned board reduces nuisance tripping and improves day-to-day performance.
Capacity for modern living
Today’s homes draw far more power than older boards were designed for.
Cleaner, more serviceable system
Clear labelling and tidy circuit layout make future servicing faster and safer.

FAQ
How do I know if my switchboard needs upgrading?
Common signs include an older board with limited protection, frequent tripping, renovations or appliance upgrades planned, or a board that’s crowded, poorly labelled, or difficult to service. We can inspect and advise.
What are RCDs and why are they important?
RCDs (residual current devices) provide additional protection by detecting electrical leakage and disconnecting power quickly. They are a key safety feature in modern residential electrical systems.
Can you upgrade the board without rewiring the entire house?
Often, yes. Many homes can have a switchboard upgraded and circuits improved without a full rewire, depending on the condition of existing wiring. We’ll assess and recommend the safest path.
Will a switchboard upgrade help with nuisance tripping?
In many cases, yes. Tripping can be caused by overloaded circuits, aging protection devices, or wiring faults. A modern board and correct circuit planning can improve reliability.
Can you prepare the switchboard for future upgrades like EV charging?
Yes. We can plan capacity and circuit layout so future additions are simpler and more cost-effective.
How long does a switchboard upgrade take?
It varies by home and complexity, but we’ll provide a clear plan including any required shutdown windows before starting.
Do you provide compliance testing and documentation?
Yes. All work is completed to the required standards with appropriate testing and documentation.
