Mounting a TV looks straightforward but there are several ways it can go wrong — here's when DIY makes sense and when it's worth getting help.
When DIY TV Mounting is Fine
If you're mounting a TV under 55 inches onto a solid brick or block wall, and you're confident using a drill and stud finder, DIY is perfectly reasonable. You'll need a spirit level, the right wall plugs for your wall type, and a bracket rated for your TV's weight and VESA pattern.
When to Call a Professional
Plasterboard (stud) walls need specialist fixings or reinforcement — a standard wall plug will pull straight through. TVs over 55 inches on plasterboard often need noggins added inside the wall. If you're not sure what's behind your wall, or if cable management behind the wall is needed, it's worth calling in a professional.
What Does Professional TV Mounting Cost?
In the Hertfordshire area, professional TV mounting typically costs from £120 for a standard installation on plasterboard or brick for TVs up to 55 inches, and from £140 for larger screens. This includes the bracket (or you can supply your own), levelling and basic cable tidying.
Our Recommendation
If it's a straightforward brick wall and a TV under 50 inches, confident DIYers can absolutely do this themselves. For anything on plasterboard, over 55 inches, or where cables need to be hidden inside the wall, the professional cost is modest and avoids the risk of a TV coming off the wall.
