Can You Mount a TV Yourself? – Fix in London Blog

Mounting a TV on the wall is one of the most popular DIY jobs in British homes. With a bracket kit from a hardware store, a drill, and a couple of hours, it seems totally doable. And often it is — but there are real risks that many homeowners underestimate. Let's go through the pros, cons, and when to call a professional.

The Case for DIY TV Mounting

Saves money on labour (professional mounting typically costs £60–£150 in London)
Satisfying to complete yourself
Works well if you have a masonry wall and can identify studs correctly
Many bracket kits include clear instructions

The Risks You Need to Know About

Hidden cables and pipes: Drilling into a wall without checking for buried cables or water pipes can cause serious damage — or injury. A cable/pipe detector is essential, but not foolproof.

Plasterboard walls: In many London flats and modern builds, internal walls are hollow plasterboard. Drill into this without hitting a stud and the bracket won't hold — a falling TV can cause significant property damage and personal injury.

Wrong fixings: Using the wrong type of wall anchor for your wall material is a common DIY mistake. The bracket may hold initially but fail over time under the weight of a large screen.

Incorrect height and angle: Getting the height wrong is an easy mistake that most people only notice after the job is done. The ideal viewing height is eye level when seated — typically 100–110 cm from the floor to the centre of the screen.

When Should You Call a Professional?

TV is 55" or larger (heavy brackets need precise fixing)
You're not confident identifying your wall type
You want cables hidden in the wall (requires electrical knowledge)
You're in a rented property (avoid deposit disputes with professional installation)
The wall is tiled or has a specialist finish

How Much Does Professional TV Mounting Cost in London?

💡 The Verdict
