Most cost effective is ventilation - trickle vents open in your windows and get the windows opened when you can (at opposite sides of the flat to encourage air flow through the rooms).

Dehumidifier will definitely reduce moisture as others have said, but can be a bit power-hungry! As others mention, the efficiency of your heating will improve with a dehumidifier as dry air heats faster (consider how quickly you can heat air (e.g. in the oven or with a hair dryer vs.heating the same volume of water).

Don't dry your clothes on the radiator, it's not heat but air flow that will dry them. Ideally, dry things outside when the weather allows. If you can, get an airer and put it in a room with the window open and shut the door to keep the rest of the place warm (towel along the bottom of the door to reduce draughts).

Avoid putting big items of furniture like wardrobes against external walls (if possible) as the lack of airflow can harbour the moisture as the wall is cooler than the air in the room.

Have the extractor running or a window open when you bathe/shower, and immediately squeegee the shower screen/ bath etc. - and moisture you can run down the drain prevents you having to extract it from the air later.

If you get wet windows, squeegee them in the morning, mop up the water and dry the towel outside or in the room with an open window.

I'm lucky to be in a well-insulated new-build now but my first place was a 1930s 4-in-a-block with single glazing and you've just taken me back to those winter days of frost on the inside of the glass and the windowsills flooding when it melted because the weep vents to the outside were frozen over! Great times...
