Went into the roof above the en suite yesterday, looking for lighting
circuit cables, and realised that the extractor that vents into the
roof space is covered by insulation! The same for the bathroom one as
well. 1988-vintage property built by Bloors.

Nearly as good as one I fixed last week. One toilet extract blowing into
the next toilet, and only one fan installed - nothing to the outside at all.
All done by a 'professional' building company. Customer had believed for 14
years that he had two extractors:-)
