It sounds like there is some kind of creature in the chimney breast. My husband phoned me last week to tell me he thought something was in there but the noises stopped so he thought it had gone. I feel really freaked out! I’m in the quiet kitchen and I can hear it moving every fifteen seconds or so. Just shuffling movement/scratching noises. Wouldn’t there be cheeping if it was a bird? I’ve seen no droppings anywhere in the house either. The chimney breast is covered over on both sides - one side boarded with an air vent at the bottom, which is where we can hear the sound coming from. The other side is a gas fireplace. Who do I call?? I’m worrying that a rat might come out of the vent at any moment.
