TV media walls look like a simple joinery job — floating shelves, a recessed screen recess, some LED strip lighting — but behind the front panel there's usually a wall-mounted bracket taking real weight, cable runs that need routing without being seen, and sometimes an AV receiver or games console generating heat inside an enclosed space.
A specification that only describes the visible finish and skips the technical detail behind it is the one most likely to cause a problem you can't see until the equipment overheats or the cables can't be reached again.
Screen mount and weight loading
The bracket brand, weight rating and fixing method into the wall (masonry plugs, stud noggin, or a ply backing board spanning studs) should be specified, since a modern large-format TV is heavier than it looks and needs solid fixing behind the media wall panel, not just fixed to plasterboard.
If the media wall itself is a stud-built false wall rather than fixed to an existing masonry wall, the quote should confirm additional noggins are built in specifically to take the bracket load — this needs deciding before the studwork goes up, not after.
Cable routing and containment
Cable routes from the screen recess down to sockets or a media shelf should be described as containment (conduit or a cable channel) rather than cables simply pushed through a gap, both for a tidy finish and so cables can be pulled through again later if equipment changes. HDMI, power and any network cable runs should each be accounted for.
Where cables need to cross a stud wall cavity, fire-stopping requirements at any cable penetration through a fire-rated wall (such as one separating a flat or between floors) should be considered, and this is a point to raise with your fitter if the property has separated dwellings.
Ventilation for enclosed AV equipment
If an AV receiver, games console, Sky box or similar equipment sits inside an enclosed media wall cabinet rather than in the open, ventilation needs specifying — vented back panels, gaps for passive airflow, or in some cases a small quiet fan. Sealed equipment cabinets are a common cause of overheating shutdowns and shortened equipment life.
The quote should state where any equipment shelf sits relative to the enclosure and confirm airflow path, not just describe the cabinet as 'AV storage' without addressing heat.
Floating shelf loading and lighting
Floating shelves need a stated bracket or batten fixing system and weight rating if they're intended to hold speakers, ornaments or books, since a purely decorative floating shelf bracket will not take real load. LED lighting strips should specify the transformer location, dimming capability if wanted, and whether the strip is replaceable without dismantling the joinery.
What cheap media wall quotes leave out
Making good to the existing wall and skirting where a false wall is being built in front of it, and confirming who supplies and terminates the aerial or satellite feed into the recess, are common gaps. Also check the quote states clearly whether an electrician is doing any additional socket work behind the media wall, since this needs coordinating before the joinery panel is closed up.
Common questions
Does a media wall need extra structure for the TV bracket?+
If it's built as a stud false wall, yes — noggins should be built in at the right height to take the bracket load, decided before the studwork is closed in. Fixing a heavy screen into plasterboard alone is not adequate.
Why does enclosed AV equipment need ventilation?+
Receivers, consoles and set-top boxes generate real heat, and sealing them into an unvented cabinet is a common cause of overheating and premature failure. The design should include vented panels or airflow gaps around any equipment shelf.
Should cable routes be enclosed in conduit?+
It's good practice, both for a tidy look and so cables can be replaced or added to later without opening up the joinery. A quote that just says 'cables hidden' without describing containment is leaving that detail to chance.
