How to Hide Television Cables Safely at Home

A wall-mounted TV can look spot on until a power lead, HDMI cable and aerial wire are hanging below it. Knowing how to hide television cables safely makes the finished job look cleaner, but safety must come before appearance. The wrong method can put strain on cables, create a fire risk or leave you with a wall that is difficult to repair later.

For most homes, the best solution depends on the wall type, where the nearest socket sits and which devices are connected to the television. A straightforward surface trunking job may be ideal in a rented flat, while a properly planned recessed cable route can suit a homeowner creating a permanent media wall.

Start by separating power from signal cables

Not all TV cables should be treated the same. HDMI, aerial, Ethernet and speaker cables carry low-voltage signals. They can usually be routed through suitable cable trunking or, where appropriate, inside a wall using the correct products.

The television's mains power lead is different. Standard TV power leads and extension leads should not simply be pushed through a hole in plasterboard or hidden loose behind a wall. They are not designed for that use, can be damaged by sharp edges or movement, and are difficult to inspect once covered.

If you want no visible power lead beneath a wall-mounted TV, the proper answer is usually a socket installed behind the screen by a qualified electrician. This gives the TV a safe, accessible power source without burying a flexible lead in the wall. It is particularly worthwhile where the TV will stay in place for years.

Keep power and signal cables separate where possible. Running them closely together for a long distance can sometimes cause interference, especially with aerial or audio cables. It also makes future fault-finding much easier when each cable has a clear route.

Choose the right way to hide television cables safely

There is no single best method for every property. The neatest result is not always the most sensible result, especially in rented homes, new builds or rooms where access to electrics is limited.

Surface trunking: tidy, practical and easy to alter

Paintable cable trunking is often the quickest safe option. It fixes neatly to the wall, holds low-voltage cables out of reach and can be painted to match the surrounding finish. Good-quality trunking has a removable cover, so cables can be replaced or added without opening the wall.

It works well when a TV socket is below the television, or when the route needs to travel to a cabinet holding a games console, Sky box or soundbar. Choose trunking wide enough for the cables you have now and a little spare room for future additions. Overfilling it can trap leads, make the cover pop off and create an untidy finish.

Surface trunking is also a sensible choice for tenants because it involves minimal alteration. Always check your tenancy agreement before drilling or fitting anything to the wall.

Concealed low-voltage cable routes

For a more built-in appearance, low-voltage cables can be routed behind the wall using purpose-made brush plates, grommets or cable entry plates. The openings sit behind the TV and behind the media unit, so HDMI and aerial cables disappear from view while remaining easy to feed through.

The cable route needs planning before the TV bracket goes up. There must be enough space behind the screen for connectors, especially if the TV sits close to the wall. Right-angle HDMI adapters or suitable low-profile cables can help, but they must not force the cable into a sharp bend.

Use cables rated for in-wall installation where the cable will be permanently enclosed. This is a small detail that makes a real difference to long-term safety and reliability. Cheap cables may work on day one but can be difficult to replace if they fail inside the wall.

A socket behind the TV

A socket behind the television gives the cleanest finish for a fixed installation, but it must be installed correctly. The socket position needs to avoid clashing with the TV bracket, mounting points or the rear of the television. It also needs to remain accessible enough for safe isolation and future work.

A qualified electrician should assess the existing circuit and install the socket to the required standard. Do not attempt to extend a socket by joining wires inside the wall or rely on a hidden multiway extension lead. Those shortcuts can create serious problems that are not visible until something fails.

Media walls and stud partitions

Stud walls can be ideal for hiding cables, but they need careful checking first. New-build plasterboard walls may contain timber studs, metal studs, insulation, pipes or electrical cables. The wall may also need a specific fixing method to safely support the TV's weight.

Before drilling, locate the studwork and check for services. The cable route should be kept away from fixings and protected from sharp metal edges. If there is insulation inside the cavity, avoid compressing or disturbing it more than necessary.

On solid brick or concrete walls, concealed routes involve chasing into the wall and making good afterwards. That can look excellent, but it is more disruptive, creates dust and may not be suitable for every property. Surface trunking is often the more practical choice if the room is already decorated.

Plan the TV position before drilling

Most cable problems start because the television position is decided before the sockets, devices and bracket are considered. Measure the location of the power socket, aerial point and any media cabinet first. Then check the height of the TV from your normal seating position.

A television mounted too high can cause neck strain, while one mounted in the ideal viewing position may leave a short power lead unable to reach the socket. It is better to identify that issue before the bracket is fitted than after the wall has been drilled.

Also consider the equipment connected to the TV. A simple Freeview television may only need power and an aerial cable. A family set-up can include a soundbar, console, streaming box, Ethernet cable, satellite feed and several HDMI connections. Planning for those cables now avoids having to reopen the wall later.

For televisions on swivel or full-motion brackets, allow extra cable length for movement. Cables should form a gentle loop behind the screen without being pulled tight when the TV is extended or angled. Test the full range of movement before fitting trunking covers or closing any cable route.

Avoid these common cable-hiding mistakes

A tidy installation should still be serviceable. Avoid fixing cables so tightly that they are pinched, crushed or impossible to remove. Cable ties are useful, but do not pull them hard around HDMI, aerial or power cables.

Do not run a flexible mains lead behind plasterboard, under carpet, through a wall cavity or inside a narrow trunking channel with signal cables. Likewise, do not overload an extension lead behind a TV cabinet with a television, console, soundbar, charger and decorative lights all plugged in. Use a suitable, accessible extension solution where needed, and keep it ventilated and easy to inspect.

Avoid drilling blind. Walls can conceal electrical wiring, water pipes and gas pipes, even where a socket or radiator is not obvious. A proper cable and pipe detector helps, but it is not a substitute for understanding the wall layout and drilling cautiously.

Finally, do not use a TV bracket as a cable support. The bracket is there to hold the screen securely, not to carry the weight of bundled leads. Keep cables organised independently so they cannot interfere with the bracket's tilt or movement.

When it is worth bringing in a professional

A straightforward trunking route can be a manageable DIY task, but wall mounting is rarely only about fitting a bracket. The wall construction, fixing type, screen size, cable route and socket position all need to work together.

Professional help is particularly useful for large TVs, plasterboard and new-build walls, full-motion brackets, media wall installations and concealed cable routes. It can also save time when you want the TV, shelves, soundbar and curtain pole fitted in one visit rather than turning the room into a series of separate jobs.

We Fit All regularly mounts TVs across London, Essex and Kent, with practical advice on brackets, wall types and the cleanest safe cable route for the room. Where electrical work is needed, plan the socket position first so the finished installation is both neat and correctly set up.

A clean TV wall should never depend on hidden shortcuts. Choose a cable route that suits the property, keeps power accessible and leaves room for future changes. The result will look finished on the day and remain safe when you upgrade your equipment later.
