    Something else to bear in mind with extractor fans is they can only work well when there is a free supply of air into the room.  You might try slightly opening a window outside the bathrrom (landing / bedroom?), and then prop the bathroom door open just a bit to let the fresh air flow in without too much humidity escaping
  • If the mold is on the ceiling, it would indicate that is the coldest surface. Are you sure it is well insulated? Also ri0un-on of fan should be at least 15 minutes.
