TV wall units are returned for reasons that have nothing to do with the unit and everything to do with the wall. In our experience as a UK furniture retailer, the recurring theme is not disappointment with quality but a mismatch between what the buyer measured and what the installation actually required.
Three things drive it: wall construction that will not take the load, a television whose bracket pattern does not align with the unit, and a room whose sockets and cable routes were never in the plan. Each of these is knowable before ordering, and each is routinely discovered afterwards.
British internal walls fall into three broad types and the difference between them is invisible until you drill. Solid masonry, common in older properties and in ground floor internal walls, will take a plugged screw and carry substantial load. Timber stud walls, standard in upper floors and modern partitions, carry load only where the fixing finds the timber, and studs sit at typical centres of 400mm or 600mm. Dot and dab plasterboard, where boards are stuck to blockwork on adhesive dabs, leaves a void behind the board that catches out anyone using a standard plasterboard anchor.
A floating TV wall unit puts its whole weight, plus the weight of everything inside it, into a handful of points. Where those points land on a void rather than on timber or masonry, the fixing pulls out of the board. This is the mechanism behind most of the installation failures we hear about, and it is why the same unit succeeds in one house and fails in another.
The practical step is to identify the wall type before ordering. A detector will locate studs and cables, and tapping along the wall will distinguish a hollow stud wall from solid masonry. On dot and dab, the fixing has to reach past the void into the blockwork behind, which requires a longer fixing than the one that usually comes in the box.
Where the wall genuinely cannot be relied upon, a floor standing unit removes the question entirely. Our range of modern TV stands and units UK includes both configurations, and the floor standing option is the safer default in a rented property or an unfamiliar wall.
Screen size in inches measures the diagonal of the panel. A 55 inch television is not 55 inches wide, and two 55 inch televisions from different manufacturers can differ noticeably in overall width because of bezel design and stand configuration. Buying a unit sized against the inch figure alone is a reliable way to end up with a television that overhangs its cabinet.
The mounting pattern is the second issue and it is more precise. Televisions use the VESA standard, which describes the horizontal and vertical distance in millimetres between the four fixing points on the rear of the set. A unit with an integrated bracket is designed around a range of VESA patterns, and a set outside that range will not mount to it without an adapter plate.
Weight limits matter too. Integrated brackets state a maximum television weight, and while modern panels are light, larger screens with substantial rear housings are heavier than expected. The stated limit should be treated as a hard limit rather than as a target.
Where the television is being wall mounted separately above a unit, the bracket and the unit become independent purchases with independent requirements, and this is generally the more flexible arrangement. A dedicated fixing from our wall TV brackets UK selection lets the screen height be set for the seating position rather than dictated by the cabinet.
The most avoidable return we see is a unit that covers a socket. Once a floating unit is fixed across an outlet, that outlet becomes inaccessible, and the alternative is either to move the unit or to move the socket, which is electrical work.
Cable management is closely related. A television needs power and at least one source connection, and a soundbar, console or set top box multiplies that. A unit with a cable route cut into the back panel handles this cleanly. A unit with a solid back does not, and the cables then run visibly down the wall, which is precisely the appearance a wall unit was bought to avoid.
Cables inside walls are the safety dimension. Electrical cables run in defined zones, typically vertically and horizontally from sockets and switches, and drilling into those zones is a genuine hazard. A detector that finds live cables as well as studs is inexpensive and prevents the worst possible outcome of a wall unit installation.
Height should be set by the seating position rather than by convention. The centre of the screen sitting roughly at eye level when seated is the comfortable arrangement, and eye level from a sofa is considerably lower than eye level standing in the room while planning. Units fixed at standing eye level are a common source of the complaint that the television is uncomfortably high.
The table below lists the checks that resolve the most common return reasons. It is built from the specification requirements of wall mounted furniture and televisions rather than from any measurement of return volumes.
| Check | What to measure | Why it matters |
|---|---|---|
| Wall construction | Masonry, timber stud or dot and dab | Determines the fixing type and whether a floating unit is viable at all |
| Stud positions | Typically 400mm or 600mm centres | Fixings must land on timber, not on the board between studs |
| Television width | Actual width in cm, not screen inches | Screen size is a diagonal and does not give cabinet width |
| VESA pattern | Horizontal x vertical hole spacing in mm | Integrated brackets fit only a stated range of patterns |
| Socket positions | Height and horizontal position of every outlet | A fixed unit over a socket makes that socket unusable |
| Seated eye level | Height from floor to eye when seated on the sofa | Sets the screen centre height and prevents neck strain |
| Delivery route | Door widths and staircase turn | Long single piece units may not reach the room |
| Corner angle | Actual angle of the internal corner | Corner units assume 90 degrees, older homes rarely deliver it |
Corner units are returned disproportionately, and the reason is that an internal corner in a period property is often not square. Plaster builds up in corners, walls settle, and a unit designed as a precise right angle sits proud on one side, leaving a visible wedge shaped gap.
Alcoves beside a chimney breast present a related issue. Alcoves are rarely identical in width even within the same room, and they frequently taper from floor to ceiling. A unit measured at floor level may not slide in at the top, and a unit measured at the top may look loose at the bottom.
The practical response is to measure at three heights and use the smallest figure, then subtract a working tolerance so the unit can actually be manoeuvred into position. A unit that fits exactly on paper cannot be turned into place, and the space required to swing an item into an alcove is greater than the space it occupies once there.
Where the geometry is genuinely awkward, a floor standing unit with a small gap either side reads as deliberate, while a fitted unit with an uneven gap reads as a mistake. This is a case where the less ambitious choice produces the better looking result, and it is worth considering alongside the modern entertainment units UK that combine a media unit with adjacent shelving to absorb an irregular recess.
Identify the wall before choosing the unit. If it is timber stud, find the studs and accept that they dictate the fixing positions. If it is dot and dab, plan for a fixing long enough to reach the blockwork behind the void. If it is masonry, you have the widest choice.
Measure the television in centimetres, not inches, and note its VESA pattern from the manual or the rear panel before ordering anything with an integrated bracket. Check the stated maximum weight and treat it as a limit.
Map every socket on the wall and keep the unit clear of them. Plan the cable route before fixing, and choose a unit with a cut out in the back panel where cables will be concealed. Use a detector for live cables before drilling, without exception.
Set the height from the sofa, not from standing. Measure your seated eye level and place the screen centre near it. And measure the delivery route as carefully as the wall, because a unit that cannot reach the room is a return before it is ever unpacked. In an older property with an out of square corner or a tapering alcove, choose floor standing over fitted and let the small gap be intentional.
This 2026 report was compiled by the editorial team at Furniture in Fashion. It draws on our assessment as a UK furniture retailer of the questions customers ask before ordering wall mounted media furniture and the issues they raise with us afterwards, combined with standard UK wall constructions and stud spacing, the VESA mounting standard, standard television and cabinet dimensions, and recognised practice for locating cables before drilling. It contains no proprietary sales data, no returns data, no customer data and no survey fieldwork, and no panel provider, weighting or academic partner was involved. The reasons described are our qualitative editorial assessment of recurring issues, not a measured breakdown of return volumes.
Journalists, interiors publications and websites may cite this analysis. Please credit Furniture in Fashion as the publisher and link back to Furniture in Fashion. The report sets out our editorial assessment of recurring installation issues rather than quantified return statistics, and we ask that it is described in those terms.
Only into the timber studs behind the board, which typically sit at 400mm or 600mm centres. On dot and dab plasterboard the fixing must be long enough to pass through the void and into the blockwork behind. A standard plasterboard anchor alone is not adequate for a loaded floating unit.
VESA is the standard describing the horizontal and vertical distance in millimetres between the four fixing holes on the back of a television. Units with integrated brackets support a stated range of patterns, and a set outside that range will not mount without an adapter plate.
Measure the television rather than working from the inch figure, because 55 inches is the diagonal of the panel and actual widths differ between models. As a general rule the unit should be wider than the television so the set does not overhang, which also gives the arrangement a settled appearance.
Set the centre of the screen close to your eye level when seated on the sofa, not when standing in the room. Seated eye level is considerably lower, and mounting at standing height is the most common cause of the complaint that a television feels too high.
Because they assume a true 90 degree internal corner, and corners in older UK properties are frequently out of square from plaster build up and settlement. The unit then sits proud on one side leaving a wedge shaped gap. Measure the actual angle before ordering, or choose a floor standing unit instead.
