Media walls are one of the UK’s most popular home upgrades, and it’s easy to see why. They create a modern, built-in look that hides wires, frames your TV, and often includes shelves or a fireplace. But when people start planning one, the first big decision is always the same:
Should you build it yourself or hire a professional?
If you’re comparing DIY media wall cost with professional installation, this guide breaks down real prices, hidden costs, risk factors, and side-by-side examples so you can choose confidently.
Key Takeaways
- DIY media walls start around £700–£1,600, while professional installations usually cost £2,000–£4,500.
- Professionals handle electrics, plastering, and fireplace integration safely.
- Hidden DIY costs (tools, poor finishes, mistakes) often erase the expected savings.
What Is a DIY Media Wall?
A DIY media wall is a self-built false wall that holds your TV, cables, shelves, and sometimes a fireplace. Most DIY builds use timber studwork, plasterboard, filler, and paint.
If you’ve never built studwork or handled electrics, review a step-by-step guide such as our detailed walkthrough on building a media wall in the UK for a realistic understanding of the process.
DIY walls offer full creative control and a lower starting cost, but they rely on your accuracy, safety knowledge, and tool skills.

Skill Level Needed for DIY
DIY only works if you’re confident with:
- Accurate measuring and timber cutting
- Building stable studwork
- Plasterboarding and basic finishing
- Safe cable routing
- Understanding when an electrician is required
If you’re unsure about any of these, hiring a professional saves money long-term because mistakes are expensive to correct.
Hidden DIY Costs People Don’t Expect
These often turn a “cheap” build into an expensive repair job:
- Incorrect studwork requiring full rebuild (£200–£600)
- Poor plaster finish needing a professional redo (£150–£400)
- Incorrect ventilation around a fireplace
- Damage to cables or existing sockets
- Tools you didn’t plan for (£100–£300)
Electric fireplaces themselves are inexpensive to run, often only a few pence per hour, according to the Energy Saving Trust, but installing them incorrectly can be dangerous.
Professional Installation: What You’re Paying For
Professionals provide:
- Safe electrics (socket additions, lighting circuits)
- Perfectly straight studwork
- Smooth plastering and paint finish
- Correct fireplace ventilation
- Proper support for large TVs
- Faster turnaround
- Workmanship guarantees
For anyone planning a wall with alcoves, cladding, or a fireplace, professional installation usually offers better long-term value.
