A media wall is one of the most practical upgrades you can add to a UK home. It gives you a clean place for your TV, hides cables, and can even include a built-in electric fireplace. This guide explains how to build a media wall in UK using simple steps based on real installations and UK-specific requirements.
The process is easier when you know what materials to use, how deep the wall should be, and how to plan your TV and fire safely. Homeowners often look for inspiration first, so our media wall ideas UK 2025 guide can help you explore layouts before you start building.
What Is a Media Wall?
A media wall is a custom false wall that holds your TV, sound system, cables, and optional electric fire behind a simple stud frame. It creates a focal point in the room and keeps everything tidy. Most installations use timber studs, plasterboard, and a recessed TV bracket.
Some homeowners prefer a clean and understated look, often inspired by our luxury minimalist media wall approach, where the structure blends into the room with hidden lighting and simple finishes.
What You Need Before You Build a Media Wall
Planning is the most important part of the build. This section covers the decisions that shape the frame, depth, and electrical requirements of your wall.
Choosing the Right Location
Pick a spot that aligns naturally with your main seating area. The TV should sit at eye level when seated, and the wall should not block radiators, windows, or doors. If your home has an existing chimney breast, you can build around it to gain extra depth.
Check where your power sockets are located. Many homeowners choose positions that reduce the need for extensive electrical changes.
Picking the TV Size and Height
Your TV determines the width and depth of the wall. Larger screens need wider recesses and stronger frame supports. Most UK installations use TVs between 55–75 inches, but any size works as long as the frame is designed around the VESA mount pattern and weight.
Keep the viewing height comfortable. A TV placed too high is a common mistake and makes long viewing sessions uncomfortable.
Selecting an Electric Fireplace (Optional)
If you want a fire in your media wall, choose a model designed for recessed installation. The manufacturer’s manual will show the exact recess size, ventilation needs, and safe distances from the TV. Some fires blow heat downward, which helps protect the TV above.

Depth, Recess, and Clearance Requirements
Depth is one of the biggest planning points. Most walls need 150–300mm depending on the fire, cables, and frame materials. The TV recess must fit the mount and allow space for cables. The fire recess must follow the manufacturer’s instructions to prevent overheating.
Always check the minimum clearance between the fire and TV. Specific numbers vary by model, so the manual is your primary guide.
Tools and Materials You’ll Need (UK)
Most UK media walls use the following materials:
- Timber studs (C16 or C24 grade)
- Plasterboard or fire-rated plasterboard (near the fire if required)
- Screws, fixings, brackets, and joint filler
- Spirit level, drill, saw, and stud finder
- Cable plates, conduits, and LED lighting strips
If you plan to install new power outlets, ensure the work follows UK electrical safety guidance found through organisations like NICEIC.
How to Build a Media Wall UK (Full Step-by-Step Guide)
This section breaks down the entire process into simple steps based on common UK building methods.
Step 1 – Measure and Mark the Layout
Measure the TV and fire, then mark the positions on the wall using painter’s tape. This helps you visualise the final design and ensures the frame is built to the correct size. Check where your cables will run and confirm whether new sockets are required.
Measure the total depth of the TV, bracket, and fire to confirm the overall wall depth.
Step 2 – Build the Timber or Metal Stud Frame
Construct the frame using C16 or C24 graded timber. Fix the base plate to the floor and the head plate to the ceiling. Add vertical studs at even spacing. Create the TV and fire recesses by adding horizontal supports at the correct heights.
Ensure the frame is level and square. A strong frame prevents movement when the TV is mounted. If you plan to include alcoves or shelves, shape them now.
Step 3 – Run Cables and Power Safely
Route HDMI leads, ethernet cables, and speaker cables through conduits or brush plates. Keep power cables separate from low-voltage cables to reduce interference.
If you need a new fused spur or power outlet, use a registered electrician to meet Part P requirements. You can find UK-approved contractors through the NICEIC website.
This step also includes wiring for LED lighting. Keep drivers and connectors accessible so they can be maintained easily.
Step 4 – Install the TV Bracket and Fireplace
Secure the TV bracket directly to the studs for stability. Match the bracket with your TV’s VESA pattern. Check the weight rating before installation.
Slide the electric fire into the recess and follow the manual for securing it. Built-in fires often need air space around the casing, so leave the recommended gap. If your fire directs heat forward or downwards, check the safe distance between the fire and TV.
Step 5 – Board, Plaster, and Finish the Wall
Fix plasterboard onto the frame using drywall screws. Use fire-rated plasterboard if your fire’s manual recommends it. Fill the joints and screw holes with joint compound, then sand lightly once it dries.
Add a mist coat before painting. Many homeowners choose simple finishes so the wall blends with the room. Panels, tiles, or wooden slats can be added for a decorative look.
Media Wall Costs in the UK
Costs vary depending on the TV, fire, materials, and labour. DIY builds reduce expenses, but they require more time and skill. Professional builds offer cleaner finishes, especially for plastering and electrical work.
Electric fires often make up a large part of the budget, and depth requirements can influence the total cost of timber and plasterboard.
Safety Rules and UK Electrical Guidance
Any new electrical work must follow UK building regulations, including Part P for domestic installations. If you are creating new sockets, a competent or registered electrician should complete the work.
Always follow the manufacturer’s manual for your electric fire. This includes recess sizes, ventilation needs, and heat clearances. Manuals provide the most accurate safety requirements for each model.
Common Mistakes to Avoid When Building a Media Wall
Many mistakes come from rushing measurements or ignoring the manual. Placing the TV too high, choosing the wrong fire size, or building a frame that is too shallow are common issues. Others forget cable routes or use insufficient stud support.
Planning carefully and following each step prevents most problems.
Final Thoughts
Building a media wall in the UK is easier when you plan the layout, recesses, and electrics before you start. With a solid frame, proper cable management, and safe electrical work, your media wall will look neat and last for years. Use design guides during planning to help shape a layout that suits your home.
FAQs
1. Can I build a media wall myself?
Yes. Many people build their own media walls, although electrical work should follow UK rules and be completed by a registered electrician.
2. How deep should a media wall be?
Most walls need 150–300mm, depending on the fire, cables, and frame thickness. Always check the fire’s instruction manual for the required recess depth.
3. Do I need planning permission?
No. Media walls are internal features, so planning permission is not required in the UK. Electrical work may need certification depending on the type of installation.
4. Will an electric fire damage my TV?
No, as long as you follow the recommended clearance distances from the manufacturer. Some fires are designed to blow heat forward or downward to protect the TV.
5. What is the cheapest way to build a media wall?
Using standard studs, basic plasterboard, and a non-recessed fire reduces costs. DIY labour also helps, but electrics should always be handled by a professional.
