This will sound really stupid - anyway I live in a converted Victorian flat (mortgaged), the ground floor and part of upstairs (huge house) is mine. we're in a terrace.
Next door we had new neighbours move in during the summer. I don't know if they've got a new shower or something but the noise in my bedroom from 5.30am is really loud - it must come through the walls or something. the dad gets up then and then the mum, it sounds like a particularly strong pump.
I know I have noise sensitivity sometimes but I can hear this even with gel earplugs and I don't get up until 7.30am.
what can I do? I can't ask them to not get up/shower. I think I was spoiled as previous neighbours worked away during part of the week and the partner of previous neighbour got up 8am so not a problem.
