Cable Clutter: Survey of 1,000 UK Households on Media Unit Wiring

We should deal with the title honestly before anything else. We have not surveyed a thousand households, and this report contains no survey results. We do not commission fieldwork, and publishing percentages from a study that was never carried out would be worthless to the journalists and readers this analysis is written for. What follows is our editorial assessment as a UK furniture retailer of a problem we see constantly and can describe precisely.

The problem itself is simple to state. Media wiring in British living rooms has grown faster than the furniture designed to hold it. A television used to be one plug and one aerial lead. A modern setup adds a soundbar, a streaming device, a games console, a router, a subwoofer and a charging point or two, and that collection is routinely asked to hide behind a slim unit that was designed when three cables was a lot. The result is not a tidiness failure on the part of households. It is a specification mismatch.

Key findings at a glance

• Cable volume in living rooms has grown while media unit depth has shrunk, which is the root of the problem rather than untidiness.
• The critical dimension is the gap between the back of the unit and the wall, not the width or the styling of the unit.
• Wall mounted televisions create the hardest cable problem because the run has to travel vertically between screen and unit.
• Skirting boards prevent most furniture from sitting flush to the wall, which is a useful accident that creates a natural cable channel.
• Heat matters: routers, consoles and amplifiers need airflow, and cable management that seals a compartment completely causes a different problem.
• Open shelf media units look cleaner in photographs and perform worse in reality than units with backs and cable apertures.

Why the wiring outgrew the furniture

Two changes happened at once. Televisions became thinner and lighter, which allowed media units to become lower and shallower, and in many homes allowed the screen to leave the unit altogether and go on the wall. At the same time the number of connected devices around a television multiplied.

The furniture followed the screen rather than the devices. A 30cm deep unit looks right beneath a slim wall mounted television and is a genuinely awkward home for a games console, an amplifier and a coiled length of spare HDMI cable. Depth, once lost, is difficult to recover, because in a British living room of typical size every centimetre of depth taken by the media wall is a centimetre removed from the walking route or the sofa distance.

Power is the other constraint. Older British homes frequently have fewer socket outlets than current use requires, and a single double socket behind a media wall is a common finding. Everything downstream of that, the extension lead, the multi way adaptor, the tangle at skirting level, follows from the socket count rather than from any decision the household made about tidiness.

The dimensions that actually solve it

Cable management is a measurement problem before it is a product problem. The table below sets out the clearances that make wiring manageable, drawn from standard furniture dimensions and common British construction rather than from any survey.

Element	Workable dimension	Why it matters
Gap between unit back and wall	Minimum 5cm, 8cm if a plug sits behind	A moulded plug alone projects several centimetres from the socket face
Cable aperture in the unit back	At least 6cm across	A fitted HDMI or power plug will not pass through a small hole
Compartment depth for a console or amplifier	35cm to 40cm	Device depth plus the cable bend radius behind it
Ventilation gap above an enclosed device	5cm clear	Routers and consoles throttle or fail when heat cannot escape
Vertical run for a wall mounted screen	Behind wall or in trunking	Screen to unit is the most visible cable run in the room
Skirting board projection	Typically 1.5cm to 2.5cm	Creates a natural channel most units can exploit

The aperture size is the one that catches people out most often. Many media units have a neat round cable port that a bare cable passes through easily and an assembled plug does not, which forces the whole installation to be done in the wrong order or the cable to be routed around the outside.

Wall mounted screens and the vertical run

A wall mounted television is the arrangement most households want and the one that creates the hardest wiring problem, because the cables have to get from the screen down to the devices without crossing open wall.

There are three honest solutions. The cleanest is to run the cables inside the wall, which in a plasterboard partition is straightforward for a competent installer and in solid masonry means chasing. Mains cable concealed within a wall is work that should follow the electrical safety requirements set out in the Building Regulations for England, covered by Part P for electrical safety in dwellings, and it is properly a job for a qualified electrician rather than a weekend task.

The second is surface trunking painted to match the wall, which is visually acceptable, quick and entirely reversible. This is the right answer in rented property where fixings and chasing are not permitted.

The third is to abandon the wall mount and put the screen back on the unit, which hides every cable behind the furniture with no building work at all. In smaller rooms this is frequently the better outcome, and a well proportioned piece from our modern TV stands UK range will conceal the entire installation without touching the wall.

Heat, access and the hidden cost of sealing everything in

The instinct with cables is to shut them away completely, and taken too far it causes two problems.

The first is heat. Routers, consoles, amplifiers and streaming boxes all generate it, and an enclosed compartment with no rear aperture and no ventilation gap will run hot. Equipment in that situation runs slower, gets louder as fans compensate, and has a shorter life. A media unit that traps heat is a worse outcome than a visible cable.

The second is access. Anything that has to be unplugged periodically, and routers in particular, should be reachable without dismantling the furniture. When a household has to move a heavy unit to restart a router, the router eventually ends up on the floor beside it, which defeats the whole exercise.

The workable middle position is closed at the front, open at the back, ventilated at the top. Doors or drawers hide the equipment from the room while the rear of the unit stays open to the wall cavity. Closed fronted designs among entertainment units UK handle this far better than open shelving, which shows every cable from every angle.

What this means for UK homes

Count your devices and your sockets before choosing furniture. If the count of plugs exceeds the sockets available, the real fix is more socket outlets installed by a qualified electrician, not a longer extension lead hidden behind a cabinet.

Buy for depth rather than for the screen. Match the compartment depth to your deepest device plus around 5cm for the cable bend behind it. A unit that is beautiful and 25cm deep will not hold a games console properly, whatever the photograph suggests.

Check the cable apertures physically. Look for openings large enough to pass an assembled plug, and prefer several small openings distributed across the back to one central hole, because it shortens every run.

Leave the equipment breathing. Five centimetres of clear space above anything that gets warm, and an open back rather than a sealed one. And if you rent, use painted surface trunking for any vertical run: it is reversible, it costs very little, and it makes a wall mounted screen look deliberate rather than improvised. Where the room has no suitable wall, a shallow piece from the modern sideboards UK range with drilled apertures can carry the equipment instead.

Methodology

This 2026 report was compiled by the editorial team at Furniture in Fashion from our editorial assessment as a UK furniture retailer of how media units are used and where cable management fails, together with standard furniture dimensions, common British construction details such as skirting projection, and published regulatory context, specifically the electrical safety provisions for dwellings under Part P of the Building Regulations for England. No survey fieldwork was carried out and no household survey data is published here, despite the framing of the title: we hold no such dataset and would not publish figures we could not verify. The report contains no proprietary sales data and no panel research.

Frequently asked questions

How much space should I leave behind a TV unit for cables?

At least 5cm, and closer to 8cm where a moulded plug sits directly behind the unit, since the plug body alone projects several centimetres from the socket face.

How do I hide cables from a wall mounted television?

Either run them inside the wall, which should be done by a qualified electrician in line with Building Regulations electrical safety requirements, or use surface trunking painted to match the wall. Trunking is the sensible option in rented homes.

Do enclosed TV units cause equipment to overheat?

They can. Routers, consoles and amplifiers need airflow, so leave around 5cm of clear space above them and choose a unit with an open back rather than a fully sealed compartment.

Are open shelf media units better for cable management?

Generally no. They look tidy in photographs but expose every cable from every angle. A unit with doors or drawers at the front and an open, apertured back conceals far more while keeping the equipment ventilated and reachable.
