If it's that loud and disruptive then you could call the non e.ergency police number (101 I think?) to come round and have a word with them.
Ha. No.
Years ago I was having a very bad few weeks - my mum was in a hospice and I was spending every waking moment there, and I was in agony waiting for an operation myself.
Came home one night and our new neighbours (adjacent semi detached building, attic flats) started a party at 11pm with the loudest, most obnoxious EDM - each track got worse and worse. They had a balcony which was next to our bedroom window - they spent the night out there whooping, yelling, screaming, laughing their heads off. I had no way to get to them as they were in the next building, didn’t even know the flat number.
Around 1am I opened the window and shouted at them to turn it down, they laughed and turned it up, then it was great fun for them to make as much noise at us as possible.
So we called 101. They told us it wasn’t a police matter and to call the council. Turns out the council phone lines close at 1am on a weekend so we had missed them.
Tried 101 once more about 4am, begging them to just send someone round and ask them to keep it down - they said they would if they had time. It didn’t stop until 8:30am so I’m guessing the police didn’t have time.
I could quite honestly have throttled the lot of them. I was so angry.
We didn’t have kids then and I can’t imahine how much worse it would have been if they’d woken our kids up like the pricks around here who set off fireworks for the entirety of November from 8pm to midnight
