Bungalows are notorious for condensation, particularly when the modern family fits pvc doors and windows to eliminate draughts.
Lack of air circulation is usually the issue.
Make sure the loft and it's walls are insulated, but it is important that there is ventilation up there, some roofs have been treated with that polystyrene insulation which seals everything up.
Quite a few folk get ventilation systems fitted.
With the cost of fuel nowadays people are having to reduce the heat, but ideally it needs to be around 20 degrees

I am not an expert either, but have had experiences with it.

I was thinking along those lines too. I've not got any working experience, but if he's the homeowner, a Mechanical Ventilation Heat Recovery (MVHR) system would fix the condensation problem and save money on heating. An MVHR system can be full property or small one for individual room. A full system, with an air-source heat pump, could pay for itself over a few years (circa 7 years or less).
