Planning a Renovation in Perth? Do Not Overlook the Electrical Work

When you plan a renovation, it is easy to focus on finishes, floorplans and fittings and leave the wiring as an afterthought. That is a costly mistake. Getting your electrical plan right from the start keeps the project safe, avoids expensive reworks, and future-proofs your home for the way you actually live. Here is why the electrical work deserves a spot at the top of your renovation checklist, and how to get it right.

Why should electrical be part of your renovation plan from the start?

The wiring sits behind the walls, so it has to go in before the walls close up. Once plaster is on and cabinetry is fitted, moving a power point or adding a lighting circuit means cutting things open again. Planning the electrical layout early, while the walls are still open, is far cheaper and cleaner than retrofitting later.

Early planning also means your lighting, power and appliances are designed around how you will use each room, rather than squeezed in around decisions that were already locked. The result is a home that works properly on day one, instead of one you are adding double adaptors to a month after moving back in.

What electrical work does a renovation usually involve?

It depends on the scope, but most renovations touch several of the same things: new or relocated power points, a fresh lighting layout, additional circuits for new appliances, and often a switchboard upgrade to handle the extra load. Bigger projects may include a partial or full rewire, especially in older Perth homes with ageing wiring.

Beyond the basics, a renovation is the ideal time to add the things that are painful to retrofit later, such as data and TV points, ceiling fans, outdoor power and lighting, and wiring runs for future additions. Doing it while the walls are open costs a fraction of doing it afterwards.

Do I need a switchboard upgrade for my renovation?

Often, yes. A renovation usually adds electrical load, whether that is a new kitchen, an extra bathroom, air conditioning or an extension. An older switchboard that was sized for the original home may not have the capacity or the safety switch protection to cover the new circuits safely.

A licensed electrician assesses your existing board against the planned work and tells you up front whether it needs upgrading. Sorting this early avoids the common trap of discovering mid-build that the board cannot support what you are adding.

When should I get an electrician involved?

As early as possible, ideally at the design stage alongside your builder or designer. Bringing a licensed electrician in early means power points, switches and lighting are placed thoughtfully, cabling runs are efficient, and the electrical work is coordinated with the rest of the trades instead of squeezed in at the end.

Calling an electrician in too late is where reworks and variations pile up. A quick planning conversation before the walls go up saves money and frustration once the project is moving.

How does renovation electrical work stay compliant?

All electrical work in Western Australia must be carried out by a licensed electrician, and renovation work has to meet the current AS/NZS 3000 wiring standard. In practice this means new circuits are protected by safety switches, the work is tested before handover, and any compliance gaps in the existing installation are addressed as part of the job.

This is not just box-ticking. Compliant work protects your household and keeps your insurance valid, and it matters later if you ever sell or lease the property.

Should I future-proof the wiring while walls are open?

Absolutely. An open wall is the cheapest it will ever be to run new cabling. It is worth thinking ahead to things like an EV charger circuit, extra data points for a home office, provision for future air conditioning, and spare capacity at the switchboard. Adding these now is far cheaper than opening walls again down the track.

A licensed electrician can talk through what is worth allowing for based on your plans, so you spend on the future-proofing that actually matters and skip what you will never use.
