You have to be careful with retrofitting insulation to any property really, nothing is risk free.
Grenfell being a worst case scenario
Other dumb things like filling wall cavities (30s housing) with spray insulation that then allows damp bridging, filling the roof void with spray on insulation that then prevents any form of maintenance, fitting external insulation that prevents brickwork from drying out.
All this stuff those Insulate Britain clowns pretend isn't a thing
