Condensation is a big problem for a lot of people and the easiest advise is to say to people 'make sure there's plenty of ventilation' - as this blows the water vapour away.
Not always tremendously helpful to have a window open in the middle of winter when you're paying a fortune to heat the flat.
Condensation (and mould) will happen in the coldest and least well ventilated bits of the flat. So if you're in an old flat and put a cupboard against a cold outside wall, don't be surprised if there's mould behind it. But it's clear you get that.
The other great way to stop condensation is to limit and ventilate activities that make steam/water vapour.
So if you're having a shower, make sure you do it with the bathroom door closed if you've got an extractor in the bathroom.
Likewise when you're cooking, use an extractor fan.
Drying clothes is often a problem. It might be, again, that doing this in a bathroom with an extractor might help.
Most of the time condensation isn't caused by a building problem, but how you live your life in the flat.
Here's the advice from the National House Builders Council
Some new homes can have structural problems - though design issues that lead to condensation are more common in older homes - such as 60s council homes where you get a thing called Cold Bridging (where you get condensation along the coldest corners by the concrete frame of the building).
If you're looking to stop the mould then regular wiping with a bleachy cloth can help to keep it under control.
Lots of very general advice, I know, but hopefully it's vaguely useful.
