Maybe 9mm plasterboard over the top and skim would save removal/repair and retain a tiny bit of insulation.
having had a peek underneath some of the tiles i'm almost certainly going to be going this route now but I'll pull all the tiles down and just go over the old ceiling as I'd rather they weren't up there. covered or not.
also from the photos i posted we stripped the wallpaper in the room with the leaf pattern and the one with the blue red single beds in about 20 minutes by hand. it was apparently only being held up by a strong belief in itself. most of the walls are back to bare plaster but a couple have crumbly paint flaking off but we have to get a wallpaper steamer for the hideous woodchip type paper in the butterfly box room, dining and living rooms anyways so I'm hoping it might also help shift some of the old paint too.
