Are your air vents closed? If so open them. You need ventilation.

Also don't dry clothes on radiators if you do so.

Vents all open, no clothes drying in room ever

Open the windows regularly to try to get a good flow of air through. You need to remove moisture from the environment.

Do you have an extract fan near your shower and in the kitchen near where you cook? Make sure you use them regularly. Is it a small apartment with a lot of cooking or showering? How many people live there?

Just to add that the problem could be exacerbated by poor insulation or cold bridging but the easiest way to solve it usually is increased ventilation.

I've had condensation come up very badly in the last six months on the windows in my apartment. Mostly in my room which is exterior walls and floor as the entrance to the carpark is under me.
Mould started to appear on the underside of the furniture so had to gut tge place and scrub it down.
I've invested in a dehumidifier, which takes about a litre of water a day out of my room and I have to keep the window open slightly all the time (even in this cold weather) to stop the pool of water being created on the windowsill. Having just the vent in the window open does not work.

The outside, thus exterior wall

Have wall checked for insulation.
It's likely that this wall in question is north - north / north west facing.

You may not be using enough heat.
Get a chemical temperature card to record your air temperature.

Advice; Use more heat / ventilate also.

Try above for a while.

Heating on every night for at least 3-4 hours at a high temperature

I have the same problem in my apartment. The dividing wall between our apartment isn't insulated and damp and mould has started on this wall since the apt became unoccupied. Was looking into getting that wall dry lined, also thinking of having our external walls cavity filled. Heat loss is terrible in these apts.
