The short answer
Textured coatings applied before 2000 may contain a small amount of white asbestos. Many do not. Only a lab test can tell.
Is it dangerous?
In good condition and painted, the risk is low. Sanding, scraping, drilling or steaming without controls can release fibres.
Your options
Leave it and paint it, overboard with plasterboard, skim over it without sanding, or have it removed with wet methods by trained operatives.
Before you start work
Test before fitting downlights, moving walls or stripping ceilings.
