I've decided that I really need to find out if it contains asbestos or not. I could rip off a small piece of the ceiling paper that it's coated onto, and get it tested. Commercial testing services that I've found on the web seem to expect you to take the sample to their premises where they'll charge you >£100 for the test. I'd have thought that local councils might have testing services, but I can't see anything on my local council's website. Any ideas about how this is normally done?
