A wall-mounted TV with a bundle of cords hanging underneath defeats the whole point. Here's how professional cable concealment actually works — and what's legal to DIY in South Australia.
How in-wall concealment works
For a standard plasterboard wall, the process is simple in principle:
- A small opening is cut behind the TV and another near floor level (usually behind a cabinet).
- HDMI, antenna and data cables are fed down inside the wall cavity between the two points.
- Both openings are finished with flush wall plates, so the result looks built-in.
On brick or stone walls, cables run in a slim surface duct colour-matched to the wall, or through an adjacent cavity where one exists.
The power cable is different — legally
In South Australia, extending or moving a 240V power point is licensed electrical work. Running a TV's power lead inside a wall cavity is not compliant, and so-called "in-wall power kits" still need an electrician to install legally. The proper solution is a new power point installed directly behind the TV — our team includes a licensed electrician, so this happens in the same visit.
What does it cost?
In Adelaide, in-wall cable concealment starts from around $149, and a new power point behind the TV from around $249. Both are quoted as a fixed price before work starts. Full pricing is on our TV installation Adelaide page.
