If I was going to do it I'd buy a kit to send off - I think it's about £30 for 1 sample and £45 for 2. The kits usually come with PPE and a marked bag to correctly dispose of them.You can get an asbestos survey for about £100 and then know for sure.
The thing is, if it *is* asbestos, the advice would be to seal it in rather than remove, which is what I am planning to do anyway. Fucked if I am going to steam off artex. I can do the floor myself with screed/leveling compound.
EDIT: I should add the floor is not artex, which is what I made that sound like - it's old vinyl tiles on concrete. If I were going to remove them I'd get them tested too, then I'd have to level the concrete once they'd been removed anyway...
