Have you got any incense sticks ..you could always light one and see where the smoke goes for .

Hot air rises, cold air sinks. Have you got an area upstairs that's unheated, or cooler than downstairs? It's not unusual to feel a draft around the stairs - could it be something like that? Start by just keeping the bedroom doors shut and see if that makes a difference.

Your draughts are thermal air currents as the hot air moves around and out through the uninsulated structure, or up to the high ceiling before cooling.

Positioning of radiators can sometimes minimise draughts

We live in a terraced house, and found when the wind blew the carpets used to belly up with the draught coming between the floorboards. So we put down hardboard on them. Works pretty well. So I think eco-friendly may well be right.

a simple candle will find any draughts.
