LOL, but not very helpful
The smell remains and I have cleaned the room completely, and I open the windows every morning for a few hours, which clears the smell. Then about an hour after they are closed the smell is back in full force.
I'm beginning to think there definitely is something in the roofspace causing this smell. My dad believes it may be bats urine which smells extremely bad, but I haven't had a proper chance to go up and have a good look about. Hopefully this will clear given time, otherwise I'll be moving out of my room
