But what is the hassle in putting 10 quids worth of plastic sheeting down
under the insulation? You'll kick yourself if you don't do it and the
condensed water drips back onto the ceiling and causes black mould stripes.

That's fine IF the majority of the insulation is above it. AND if the
joists are below it. BUT if there IS a roof leak, you won't notice it
until too late maybe...

My argument against your soulutin was moe against expensive celotex and
foil backed board.
