Electrical Wiring Considerations for Home Renovations

Are you about to embark on a home renovation? No matter how big or small your renovation is, chances are there will be some form of electrical work required. Whether you’re renovating your kitchen or bathroom or doing a full home renovation, a licensed electrician will be one of the tradespeople at the top of your list.

While you might be looking to keep your costs as low as possible, a renovation presents the perfect opportunity to take a good look at your electrical work to see what needs attention. In many cases, a home may need to be completely rewired.

To help you get a bearing on the electrical wiring for your home renovation, I thought it would be a good idea to take a look at some of the considerations. Continue reading to find what these are.

New Electrical Wiring

For those preparing for a full home renovation, there is a strong possibility that your entire house will have to be rewired; especially if you are changing the floorplan and moving existing lighting, switches and powerpoint sockets.

This, as with any electrical work, should only be performed by a qualified licenced Electrical Contractor. In terms of preparation, contact your local electrician well before you commence your renovation so they can identify any potential issues and work the electrical wiring into your renovation schedule – this is best done before the plasterboard is applied to the ceiling and walls.

Upgrade Electrical Capacity

Another electrical wiring consideration for home renovations is the electrical capacity; by this, I mean how much power is available. I find many old homes on the Gold Coast don’t have enough electrical wiring to handle today’s modern appliances and air conditioners. Moreover, these older homes also have old switchboards which provide limited space to add circuits, or they have fuses, which are now illegal.

In both cases, often the only solution is a service change or to upgrade the switch board. If you’re about to renovate, give me a call. I can calculate the existing capacity and then if need be, update the service, install a new panel, and run new wires.

Include More Outlets

One common failure I see in home renovations is a lack of power outlets. You can never have too many. It’s so much easier and cheaper for an electrician to install powerpoint and USB outlets during a renovation when they have access to the cavity of the walls than it is once the renovation is finished.

To make sure you have the right number of outlets, take your floor plan and a highlighter and mark on it all the places you need power – take into consideration all your appliances, phone chargers, iPads, game consoles, computers, TV, DVD player etc, and don’t forget about the outdoors; you’ll need power in your outdoor entertainment area, the garage and/or shed, and one by your water tank if you use a pump.

Smoke Alarm Compliance

Smoke alarm compliance has recently changed, and chances are, you will need to update your smoke alarms accordingly. As of 1 Jan 2017, all new dwellings and substantially renovated dwellings are required to be fitted with interconnected photoelectric smoke alarms. They are to be installed in all bedrooms, in hallways that connect bedrooms with the rest of the dwelling and on every floor level of the home.

Interconnected photoelectric smoke alarms must be installed by a licenced electrician. For more information on this topic, read my earlier post ‘Smoke Alarm Installation Requirements in Queensland’.


A home renovation of any size is very exciting, but it can also be a big learning curve in terms of the electrical wiring considerations. While you may be trying to get away with a budget renovation, there are no corners to cut in terms of electrical wiring and safety.  Your family’s safety is of paramount importance.

Electrical wiring consideration for home renovations includes rewiring of the entire house, upgrading the electrical capacity, including more power outlets and being compliant to new smoke alarm legislation.
