Side-by-side comparison
Plasterboard vs Brick Wall TV Mounting
Both walls can safely hold a TV when the fixings are sized to the load. Plasterboard wins on cable hiding (cables drop down inside the cavity) and is the dominant interior wall in modern UK homes. Brick wins on raw strength and is the easier substrate for very large (85"+) TVs. Cost depends on TV size, bracket and cable management — see our pricing page for the current tier breakdown.
Strong with correct cavity anchors or stud-fixing — suitability confirmed against TV weight and bracket.
Excellent — masonry anchor handles most domestic TV weights when correctly specified.
Combi drill, 6 mm bit. Quick and clean.
Hammer drill, 8 mm masonry bit. Slower, dustier.
Grip-It anchors, toggle bolts, or screws into stud.
Fischer or similar masonry anchors.
Yes — cables drop inside the cavity. Cleanest finish.
No — solid wall. Trunking or floor/ceiling routing only.
Possible with stud-fixing; cavity-only fixings typically limit at ~75".
Excellent — masonry handles 85"+ when anchors are sized to the load.
Depends on size, bracket and cable management.
Depends on size, bracket and cable management.
Almost all internal walls in homes built post-1960.
External walls, chimney breasts, party walls in older homes.
Verdict
For most living rooms, plasterboard is the better wall to mount on — not because it is stronger, but because cables disappear inside the cavity and the install is cleaner. Brick is the better choice for very large TVs (85"+) or when you specifically want maximum holding strength. See our pricing page for the current tier breakdown.
Common questions
Frequently Asked Questions
Is brick or plasterboard stronger for mounting a TV?
Brick is intrinsically stronger as a substrate. On plasterboard, a TV fixed into the timber/metal studs or anchored with cavity fixings rated to the TV's weight is suitable for most domestic TVs once the wall, bracket and load are assessed together. Bracket fixings rarely fail when sized correctly for the substrate.
Which wall is easier to hide cables in?
Plasterboard. The hollow cavity behind the plasterboard lets us drop the HDMI and power cable straight down inside the wall. Brick walls require either external trunking or routing through a floor or ceiling void, which is more involved.
Is mounting on brick more expensive than plasterboard?
Labour cost depends on wall type, TV size, bracket choice and cable management — not just the substrate. The biggest practical difference is cable hiding: plasterboard lets us route cables inside the wall (cleaner finish, often Premium tier); on brick, surface trunking is the practical option. See our pricing page for the current tier breakdown.
Can a 75-inch TV be mounted on either wall?
In most cases, yes — provided the wall and fixings are right. On brick, a properly sized masonry anchor handles a 75". On plasterboard we locate the timber or metal studs and fix into them where possible, or use heavy-duty cavity anchors whose pull-out rating exceeds the TV's loaded weight. We confirm suitability against your specific wall and bracket on the day.
