Trunking cables through chimney breast I’m hoping someone can help and advise if my plan is ok for mounting the TV to the chimney breast and hide/trunk the cables through the hollow breast down to the right and out where I will have a unit holding the av equipment. The chimney is a layer of plasterboard on top of the brick If you have a look at the photo you will see a vent right in the middle at the bottom which I have taken off and can see into the chimey The plan is to Cut part of the plasterboard out where the cross is to access the bricks Cut a hole through the brick using a circular cutter prob about 2” where the cross is Cut a hole through the brick using a circular cutter prob about 2” where the arrow is pointing too Feed the cables from where the tv will be using the vent hole to hook the cables through to the side hole Tidy the holes up with a couple of plates etc Would this be ok? If so whats the best way to remove the bricks? Apoligise for the photo. It was taken when we first moved in. can get better photos if needed but this should give an idea.
