About six months ago a group of 'young people' moved into the ground floor flat in the garden which is at right angles to mine. They have people round and are drinking in the garden and shouting every night. The gardens are not massive - only about 20-30ft wide with walls that are only about 1.5m high and their garden is only about 40ft from mine. They don't generally go on too late but it's just relentless shouting, raucous laughter and music which means that I can't sit in the garden or have windows open because they just make a constant racket. I did hear a neighbour asking them very politely to keep the noise down one evening and they were pretty rude to her. I think they assume they have the law on their side.
Is that right? If they don't carry on beyond 11pm there's nothing anyone can do? I stood on a chair this evening to see exactly which garden it was and they jeered at me
