Hidden Socket Setup
A proper media wall hides all cables completely so that nothing is visible once the TV and fireplace are installed. This is one of the key differences between a professional-looking media wall and a basic setup.
- Sockets behind TV
- Sockets behind fireplace
- Cable routing inside wall
Chasing Walls & Cable Routing
One of the biggest factors affecting electrical cost and time is how cables are routed through the wall. This varies massively depending on whether you're working with a stud wall or a solid masonry wall.
If you're building a new stud wall, running cables is relatively straightforward. Wires can be fed through the timber frame before plasterboard is installed, allowing sockets, lighting, and fireplace connections to be placed exactly where you want them with minimal effort. This is one of the reasons stud media walls are so popular, they give you complete flexibility with very little added labour.
However, if you're working with a solid brick or block wall, things become more time-consuming. Cables need to be chased into the wall using a wall chaser or grinder, which creates dust, noise, and additional cleanup work. Once the cables are installed, the wall then needs to be filled and often skimmed to restore a smooth finish.
This extra work can significantly increase both labour time and cost. What might be a quick cable run in a stud wall can turn into a much longer job in masonry, especially if multiple sockets or lighting circuits are being added.
You should also consider aerial and satellite cables, particularly if you use Sky or similar services. These cables need to be routed behind the TV just like power cables, otherwise you'll end up with visible wires ruining the finish. Planning this early is important, as retrofitting them later can be awkward and may require additional chasing or surface trunking.
LED Lighting
LED strips are often installed to enhance the overall look of the media wall and create a more modern, ambient feel. When done properly, they add a subtle glow that highlights the structure without being overpowering.
- Around the TV recess
- Inside shelves
- Under floating units
This adds a premium feel for relatively low cost.
Do You Need an Electrician?
Yes in most cases. Electrical work must be done safely and often legally requires a qualified professional, especially when adding new circuits or modifying existing wiring. Even if you're confident with DIY, bringing in an electrician for final connections and testing is usually the safest approach.
Final Thoughts
Electrical work isn't the biggest cost, but it's essential for a clean, modern finish. Getting the cable routing, socket placement, and lighting right is what separates a polished media wall from something that looks unfinished.
