We went for a full survey bvecasue we didnt know where it could be through-out the house. If you know where it specifically is in the house get the test at home kit, i.e. textured celing.
For context our artex was only 8% white asbestos so not really harmful in the tiny amount ou need to test
With regards to the asbestos question:
An asbestos survey (from an independent surveyor, not one that then wants to offer you a removal service) is £275 plus VAT
You can get test at home kits for £45/sample
I'm very suspicious of the latter (expertise, reliability, potential harm from needing to disturb a little asbestos) - should I be?
