Whilst I agree with Peter's advice I would add that we had a very
similar problem with very cold interior walls and mould in two bedrooms.
Our first action was to have cavity wall insulation installed which
provided a dramatic improvement to the apparent temperature of the walls
and ended the appearance of mould. This did, however, cause more
condensation on the double glazed windows which requires additional
ventilation to keep in check.

We recently moved to a house with full UPVC double glazing and
restricted ventilation.

After about a month, mould was popping up all over, (esp.) behing the
bed head. Made worse by cold non-insulated walls and the Mrs. drying
washing on a clothes horse !!

Got one of them de-humidifer things from B&Q £149 (a faily beefy one as
it's a large 4 bed detatched.)

Had to empty the tank every 6 hours or so for the first few days, then
every day and withing a week condensation/mould vanished never to return.

It's also a real pearl for drying clothes. I shut it in the utility room
sat under the clothes horse whith the Utility room rad. on No. 6 (on
all time) and clothes come from machine and are dry in a couple of hours
tops (even a machine full of towells). When we had high humidity it
took about 2 days to dry the clothes !!

De-humidifiers rock. I am totally converted.
