Since the cold weather started I have been experiencing terrible condensation on my conservatory roof. Would a dehumidifier solve the problem?

It would certainly help - My £160 Ebac sucks up almost a litre a day.

Also keep bathroom and kitchen doors closed when bathing/cooking - open windows to let steam out whenever possible - keep conservatory a bit cooler if possible.

As a minimum - stop the warm air from the house entering the conservatory.
