DH clearing the loft before putting in some insulation. Turns out our bathroom extractor is going straight into the loft with no pipe or way to escape. Hasn't been a problem up until now but as the insulation is about to go in it may cause problems in the future.
Is it stupid just to turn it off? I always have the bathroom window open for ventilation, even in the winter. It's loud too so I'll be glad to see the back of it.
