Adding ceiling fans to an older home: what's involved?

A room with no fan point almost always has a light point, and the lighting circuit is normally where a fan's power comes from. The electrician runs new cable from that circuit to the fan position and down to the wall switch or controller.

In an older home, look at that circuit first. Energy Safe Victoria advises owners of houses over 30 years old to have their wiring checked, and adding a fan is a good moment to find out whether the lighting circuit is fit to extend. Altering a circuit also brings in safety switch protection, because Energy Safe Victoria notes the Wiring Rules require additional RCD protection when alterations are made to an existing installation.

In a single-storey home with a pitched roof and a manhole, most of the work happens from above. The electrician can see the joists, choose a fixing point, fit a brace if needed and run cable to the wall without disturbing the ceiling. Many of the post-war brick and weatherboard homes around Altona are like this.

Period cottages can be harder. Victorian and Edwardian houses in Yarraville, Seddon and Footscray are mostly single-storey with corrugated iron roofs, and their roof spaces can be tight to move in. Older plaster ceilings crack if they're pushed from above, so the work is slower and sometimes needs a small access hole cut and patched below.

In a double-storey home, the ground-floor ceiling has no roof space above it. Cable has to be fished between floor joists or through a wall from below, and the fan position may be limited by which way the joists run.

A ceiling fan is heavy and moves, so it must hang from structure: a ceiling joist or a timber brace fixed between joists. Plasterboard or old plaster alone can't hold it. If the best spot falls between joists, a brace goes in from the roof space, which is another reason access matters.

High ceilings in older homes need a longer downrod so the blades sit low enough to move air while still clearing the minimum height in the fan's instructions. If there's an ornate ceiling rose where the old light hangs, the fan can often go there, but the rose isn't structural, so the fixing still has to reach a joist or brace above it.

The simplest setup is a fan speed controller beside the existing light switch, often on a shared plate, with the fan's light on its own switch. That needs new cable from the fan down the wall to the switch position.

DC motor fans usually run from their own remote or a matched wall control from the same maker, not a standard fan controller. Even a remote-controlled fan needs power at the ceiling and a way of switching it off, so check what the fan's instructions call for before you settle on a remote only.

If the room has downlights, keep them out from directly above the blades, or the light flickers through them. If the room has one central light, a fan with a light kit keeps the ceiling tidy.

Weatherboard and timber-framed walls usually have a cavity the cable can drop through, from a hole drilled in the top plate in the roof space. A noggin partway down can block the run, and the electrician may need a small hole in the wall to get past it.

Solid masonry, such as the basalt houses in parts of Williamstown, has no cavity. The choice there is a groove chased into the wall and plastered over, or a neat surface-mounted conduit. Installing a fan is licensed electrical work even where a light point already exists, and it comes with a Certificate of Electrical Safety.
