Adding a garage, shed, or home extension is exciting—it means more space, more functionality, and sometimes, more comfort. But before you start imagining the finished space, there’s one critical thing you can’t ignore: safe and proper wiring. Let’s break down what you need to know.
Assessing Power Needs for Your New Space
Every add-on structure has its own electrical demands. A garage might need outlets for tools, charging ports for an EV, or bright overhead lighting. A shed could require minimal power for lighting and small equipment, while an extension might need wiring for appliances, heating, and entertainment systems. The key is to plan your electrical load early, so your wiring can safely handle everything without overloading the system.
Choosing the Right Wiring Method
Not all wiring is built or performs the same. For garages and sheds, wiring may run underground from your main switchboard. This usually involves conduit wiring to protect against moisture, rodents, and wear. In an extension that’s part of your home’s structure, wiring is typically run within the walls, similar to standard house wiring. The electrician chooses appropriate cables, insulation materials, and installation techniques to ensure maximum durability and safety.
Safety and Compliance First
Electricity is not something you figure out as you go. To keep things safe and pass inspections, your wiring needs to meet local electrical rules. This includes using the right circuit breakers, installing ground fault circuit interrupters (GFCIs) where required, and making sure all connections are properly earthed. Using a licensed electrician isn’t optional; it’s the safest and smartest choice you can make.
Lighting, Outlets, and Future-Proofing
Think beyond today. Even if you don’t plan to run heavy equipment or multiple devices now, leave room for future upgrades. Install enough outlets so you’re not relying on extension cords, which can be dangerous over time. For lighting, LED fixtures are a great choice for efficiency and longevity, especially in spaces like sheds and garages where lights may be on for long periods.
To Sum Up
At Rayzr Electrical and Data, we explain that good wiring isn’t just about turning on a light — it’s about creating a safe, reliable, and future-ready electrical system for any new space. Whether a homeowner is building a garage for a dream car, a shed for weekend projects, or an extension for extra living space, we emphasise that the right wiring makes all the difference. We remind clients to plan smart and wire safely so their add-on feels less like an afterthought and more like it has always been part of their home.
