the walls are either brick/blockwork or stud/plasterboard.
they might reveal the ceiling board if they remodel the bathroom but knocking down walls isn’t really going to reveal anything and a tradesman would know if anything untoward gets revealed.
theres no asbestos reported in the communal area report apart from an encapsulated door of a store room and a ceiling panel in a bin store. it’s the not so dangerous type with the recommendation of ‘do not disturb’ and ‘monitor for deterioration’. Its better to just leave it in place than remove it.
I don't know much about these things, but does it present a risk to the next buyer of your place that doesn't know it's there and takes a sledgehammer to the wall without wearing PPE?
