Every time the neighbours mother goes out the teenager daughter parties ,shouting,loud music,the house seems full of loud kids the mother has been told but it still goes on till early hours at what point should police be called or should we just ignore it
You could report it to the local council as an environmental problem but it will have to be a lot more constant than that to get anything done. Several times a week may get a response but not '4 times in a few weeks'
Where I live the Council has set up a Noise Control unit which I think operates between 11pm and 3am on Fri and Sat. Do you not have anything like that in your area?
Surely if enough people complained the council would investigate. However, this is not really conducive to maintaining a "friendly" neighbourhood. As I said before: not a nice situation to be in.
Your council have a legal duty to deal with noise complaints. Phone them or look on the website. The first step should be to speak to the householder but they acknowledge that this is not always possible.
