Posted By Doug Kelly I think a simple answer has to be yes. Past experience of asbestos surveys (especially 'public' housing stock, MOD etc.)would indicate possible presence of ACM in the following forms e.g. loose thermal insulation, pipe / vessel insulation, insulating board, cement tanks and flues and/or debris and residues from unsatisfactory removal of the above. It can depend on the age of the building, but that's not a conclusive indicator of ACM use as any prohibitions on use of asbestos may have been circumvented by a well-intentioned householder. I'd have to recommend you get specific advice, the cost of a competent surveyor shouldn't be too restrictive, especially when set against the implications of getting it wrong.
