Use insulated wall liner to prevent mould?

We regularly have mould appearing on inside of walls of our 130 year old converted ground floor flat throughout colder months. Dehumidifier reduces damp air but three occupants means it is difficult to minimise. The age of the drilled holes and and conversation with previous owner indicates that the chemical damp proofing was probably done around 40 years ago. Problem is in front and back rooms and neighbours have similar issues. In back bedroom the furniture near the external wall causes mould, even high up. Would wallrock thermal liner work. Is there a simpler solution? Where the wall isn't visible I thought of just PVA'ing a roll of 3mm sheet polystyrene.

Why not post pics of the walls from the inside and the outside?

Your issue is ventilation, mainly. What kind of ventilation do you have in your flat?
