Just had a bloke round about cavity wall insualtion and I've been told
that I can't have it. It's a stone built property with an inner leaf of
brickwork. Apparently because the inner side of the stone is jagged it
can cause damp problems. I'm thinking that I'd like to insulate from
the inside now so may get in touch with the plasterer who is due round
next week.

The inside jagged? That is new one on me. The only way you can get damp is
if the outer wall is porous in some way.
