tell that to my dads next door neighbour.
They decided to take the fire place out and started at the bottom.
They had the whole concrete lining and the outer chimney fall in.
None of it was tied into the external wall and it was completely free

Never heard of a concrete liner in a chimney, nor have I ever seen a chimney
breast in 30 years of working in old houses that wasn't keyed in to the wall
it was built against.

Must be a regional thing as I've only really worked in a hundred mile radius
of Manchester.
