Wall Mounted TV Cable Trunking Explained

A neatly mounted screen can still look unfinished if the wires are hanging below it. That is why wall mounted tv cable trunking matters. It gives you a cleaner finish, helps protect cables from knocks, and makes the whole installation look planned rather than patched together afterwards.

For most homes in London, Essex and Kent, trunking is the practical answer when you want a tidy result without chasing cables into the wall. It is quicker, less disruptive and usually more cost-effective. Done properly, it blends in well and keeps your TV area looking sharp.

What wall mounted TV cable trunking actually does

Cable trunking is a surface-mounted channel that runs from the back of the TV down to a socket, media unit or accessory point. It hides the visible wires inside a neat plastic cover fixed to the wall. Once fitted, you see a straight, tidy run instead of loose leads.

It sounds simple, but the difference is noticeable. A good TV mounting job is not just about getting the bracket level. It is also about where the power cable goes, where the HDMI leads sit, and how everything looks when you walk into the room. Trunking turns a functional install into a finished one.

It also helps with day-to-day use. Cables are less likely to be snagged by children, pets, vacuum cleaners or furniture being moved around. If you ever need to add or swap a lead, trunking is usually easier to access than a fully chased-in cable route.

When wall mounted TV cable trunking is the right choice

In plenty of homes, trunking is the best balance between looks, speed and cost. If you live in a rented property, it is often the sensible route because it avoids more invasive wall work. In newer homes with plasterboard walls, it can also be the cleaner option where chasing out the wall is not ideal.

It is especially useful when the wall already has limited access, when the sockets are lower down, or when you want the TV up quickly without turning the room into a building site. Many customers simply want the screen on the wall and the wires hidden neatly enough that the room feels finished. Trunking does exactly that.

That said, it depends on the look you want. If you are after a completely cable-free appearance, in-wall cable concealment may suit you better. But that tends to involve more labour, more dust and more planning. For many households, neat trunking is more than enough.

Types of trunking for a wall mounted TV

Not all trunking is the same. The size, shape and finish need to match the number of cables and the wall position. A small strip may work for a power lead and one HDMI cable. If you have a soundbar, Sky box, games console and streaming device in the mix, you usually need a wider channel.

The most common option is white PVC trunking with a clip-on front. It is practical, tidy and suits most modern interiors. It can also be painted to match the wall, provided the surface is prepared properly and the paint is suitable.

There are also slimmer profiles for minimal cable runs and larger trunking sections for installations with several leads. The key is not to cram too much into a small channel. That can make the cover bow out, affect the finish and make future access awkward.

Where trunking works best in the room

The usual route is a straight vertical drop from the TV down to the power point or media unit. That tends to look the neatest because it follows the natural line beneath the screen. If the wall layout calls for it, trunking can also run horizontally, though this needs more thought to keep it looking intentional.

Position matters. If the trunking is slightly off-centre or not fully level, it will draw the eye. This is why measuring and planning matter just as much as fixing the TV bracket. The best results come when the cable route is considered at the same time as the mounting height, bracket position and furniture below.

In some rooms, the trunking can be aligned with corners, alcoves or chimney breast lines so it is less noticeable. In others, painting it to match the wall helps it blend in. There is no single answer for every property. A Victorian terrace, a new build flat and a rendered extension all need slightly different thinking.

Common mistakes with wall mounted TV cable trunking

The main mistake is treating trunking as an afterthought. The TV goes up first, then someone realises the plug socket is too far away or there are more cables than expected. That is when you end up with oversized trunking, awkward bends or wires still visible at the edges.

Another problem is using the wrong size. Too narrow and it looks forced. Too wide and it can seem bulky, especially on a smaller wall. Choosing the right trunking means knowing what equipment is being connected now, and what may be added later.

Poor fixing is another issue. On plasterboard, the trunking needs to be secure and straight. On brick or concrete, the wall may need different fixings and more care to get a crisp finish. If it is stuck on badly or fitted over uneven surfaces, gaps can appear and the cover may not sit flush.

Then there is cable planning. Power cables and signal cables may need organising properly inside the channel rather than just pushed in. It keeps the trunking easier to close and gives a tidier result overall.

Trunking or chasing cables into the wall?

This is one of the most common questions, and the honest answer is that both options have their place. Trunking is faster, cleaner and easier to alter later. Chasing cables into the wall gives the most hidden finish but involves more work and usually more cost.

If you want the room sorted with minimum disruption, trunking often wins. If you are renovating anyway, decorating the room from scratch or aiming for a very minimalist look, recessed cables may be worth considering.

There is also the wall type to think about. Solid walls, dot-and-dab walls and plasterboard partitions all behave differently. Some are straightforward for concealed cable work, some are not. A practical installer will tell you what suits the wall, the room and your budget rather than pushing one method every time.

Why professional fitting usually looks better

A lot of DIY trunking jobs fail on the small details. The line is slightly out, the cuts are rough, the cover does not sit tight, or the TV height does not work with the cable route. None of those sound major on paper, but together they affect the final look.

Professional fitting makes a difference because the whole setup is considered as one job. The bracket position, viewing height, wall type, socket location and cable route are all planned together. That is what gives you a result that looks clean rather than improvised.

For households short on time, it also saves hassle. You do not need to buy the wrong trunking twice, patch up failed fixings or try to work out why the cables still show from certain angles. A proper install should leave the room looking better, not like a part-finished weekend project.

This is especially true with larger TVs or more complex setups. Once you add a soundbar, media devices and multiple HDMI leads, cable management stops being a small extra and becomes part of the main installation.

Choosing the right finish for your home

The best wall mounted TV cable trunking is the kind you stop noticing. In most rooms, that means keeping the cable run as short and straight as possible. White trunking on a light wall often works well. On darker or coloured walls, painting the trunking can help soften its appearance.

Furniture layout matters too. If the trunking lands neatly behind a cabinet or lines up with the centre of a console unit, it tends to look more deliberate. If it runs awkwardly across open wall space, it will always stand out more.

This is where a local, hands-on service can help. In real homes across places like Barking, Dagenham, Redbridge and Newham, no two rooms are identical. A practical installer looks at the wall in front of them and fits the solution to the space, rather than forcing a one-size-fits-all setup. At We Fit All, that is the standard approach.

If you are planning a TV wall mount and want the job to look properly finished, do not leave the cable route until the end. Good trunking is not there to draw attention to itself. It is there to make the whole installation look right from the moment you walk in.
