Can I put a hole in a disused chimney breast?

Anonymous user 01/03/2024 - 2.45 PM

I live in my parents' 1930's terraced house and the chimney in the front room is disused and has been for years. I would like to mount a 42" LED TV onto the breast and, if possible, run the cables to the power supply, aerial, future amp and speakers, laptop, dvd, and so on, into the chimney, down the inside and onto a shelf in the old fire place. My question is this. What, if any, consequences could there be mounting the tv onto the breast? And again, what, if any, consequences could there be knocking a hole through the breast to run cables? I do have other options to mount the tv elsewhere is need be. Thank you for your help and assistance, I really appreciate it.

As above. No problems although make sure the chimney is correctly ventilated top and bottom to avoid condensation on your cables. I have done a similar set up recently and used 2 X 90 degree bends and a 3' length of 5" soil pipe to create a duct big enough to pass full plugs, HDMiI's even small transformers etc through. Works a treat and no wires to be seen, makes life easier for upgrades in the future as well.

You will be okay mounting the tv on the chimney breast so long as you get good fixings. You can knock a hole out for cables. Make sure you have a vent fitted low down for air circulation inside the stack to avoid damp and condensation, you also need a rain guard on top of stack.

There should be no problem as long as the chimney breast is not used for a flue for venting. If it is, more precautions need to be taken. I would also check that the chimney is capped at the top or has pepper-pots installed to stop water entering the chimney flue.
