The house may not have battened ceilings or floors but it’s the only way you’ll do this without surface trunking. It’s the customer’s choice, do they want the house to look good after the work or not?
Concrete ceilings are a structural nightmare so don’t even think of chasing in to them. There was a good thread on this subject a while ago, I can’t remember the outcome. I do remember the guy wanted to cut in to the ceiling with a Stihl saw.
Really, what a plonker lol
