Some of these replies are absolutely fucking nuts.
I would be raging inside after this long.
I live in council housing and these Issues are so hard to live with ( I have experience and understanding sadly),
There is often a different type of behaviour that I find to be feral and gutter level quite often in social housing.
The regulations are that noise needs to be lower during 11;pm to 7am - so she isn't really abiding by that.
I don't care if it's kids, I have a child who is so loud, with extra needs. I wouldn't let them in the garden before 9am, usually 9.30. Because I'm not a total cunt.
I've done the stfu out the window before and find it can often lead to long-standing problems.
I have learnt that the formal route tends to work best.
Councils can have anti social behaviours teams, maybe neighbourhood housing officers still - hopefully.
I would telephone and ask to speak to the housing team at this stage - not environmental health. The housing team or anti social behaviour team. Explain the significance of the impact. Highlight the 7am rule.
It's not ok and she can stick those kids in front of the TV until 9 and suck it up imo.
You could call anonymously first and ask what they can do about this type of scenario. I would ask for a resolution because saying sorry can't help is not ok. I don't believe they would say that tbh.
The usual thing is to send a letter out, something generic like ' be mindful of the time you're creating noise and be considerate of your neighbours.' I've had issues where this was done on my behalf and certain things got better.
If I was buying and saw that ( a call and a letter), it wouldn't be enough to put me off buying.
