Blocking up two fireplaces.

Jasontenn · 2025-12-11T10:25:26+0000

I have a 1930’s semi which I am currently renovating. There are two fireplaces, one in the living room and one in the dining room. Both these rooms share the same chimney which comes down through the main bedroom and then branches off at celling height in the living room into the two separate rooms.

I am removing the fireplaces from both (the living room had an old gas fire and dining room an electric fire and blocking them both up.

My question is, do I need to put an air brick or vent of some description and if so does it have to be in both blocked up fireplaces or can I get away with it being in just one of them?

Yes, and both needed.
