Ok it's a one off but it's been going on since 2pm relentlessly. They're 7 doors down including round a bend so I really feel for the next door neighbours. I've looked at the council website and there's no contact for "now issues" only repeated offences. I don't know the neighbours in question. Dh says give it until 10pm and he'll go round but is that being unreasonable? FWIW we have two young kids, one of whom can't sleep for it.
