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.

Would this be ok? Yes, I done this for my grandparents TV. Just drilled through into the chimney cavity. No need to cut out any plasterboard or brick.

Their chimney was still in use at the time so I boarded it up and put shelves in place of the fire to hold the sky box etc.

Thanks for the reply. What do you use to drill through? A core drill bit? I’m thinking a 2” core drill bit will be wide enough to fit a plug through.

A core drill would be perfect for the job. I just drilled a series of 13mm holes beside each other with a regular drill bit. It's worth noting that the masonry drill bit wouldn't go through the liner of the chimney and I had to hammer a piece of steel rod through it. It broke through easily enough, just wouldn't drill.
