I moved into my flat a few months ago (bought on shared ownership) and since day 1 all I have heard from upstairs is constant banging, kids screaming, feet running up and down and even phones vibrating at 5 in the morning! It's horrendous. As part of our leasehold, we're not allowed to have wooden floors, they definitely do not have carpets that's absolutely apparent.
The people that live upstairs are a family of 4. The first time I spoke to them about it I bumped into the husband and mentioned it to him (I'd been there 2 weeks by that point) he said 'ah I knew you were going to mention that', insinuating that the previous owners had also complained. He was very polite and apologised saying that they would keep it down. As time has gone on it has gotten worse. He also accidentally let it slip that they had wooden floors. There are moments when the ceiling shakes and the banging is unbearable, I go upstairs to speak to them but they pretend that they're not home.
I wrote them a note and asked if they could consider carpet, the wife then wrote back saying it's her property and she can do whatever she wants (she can't) and that the kids are small so they make noise etc. She also lied and said that they have carpet with an underlay.
A few people in the building have wooden floors but from what I know they're not receiving complaints as they're decent human beings that don't move around the place like bulldozers. I've reported this to the housing association but nothing is being done. Advice please!!!
