Step by step

How an experienced tradesperson would think through it.

Check TV weight and bracket compatibility.
Decide height from the seated viewing position, not just from standing eye level.
Identify wall type: solid masonry, stud wall, dot-and-dab or plasterboard system.
Scan for cables and pipes before drilling.
Mark bracket holes with a level.
Drill using the correct bit and depth for the fixing.
Tighten the bracket securely and hang the TV with help.
Check level and cable strain before letting go.

Professional tipsMost TV mounting failures come from wrong fixings, not wrong brackets.A slightly lower TV often feels better than a high showroom-style position.Cable planning should happen before drilling holes.
