We've just moved into a flat with (in my opinion) horrible bumpy textured walls and ceilings. I've been reading that these could be artex and contain asbestos. As we're considering attempting to remove this effect, or else plaster over it, I'm looking into asbestos checks. However, before jumping into this I wanted to check I haven't got the wrong end of the stick and was hoping someone could have a look at the photos below and confirm whether it looks like artex is a possibility, or is it more likely to be regular plaster? It isn't laid on very thick.
