Hello Anon143, a warm welcome to the forums, and I know, not that I'm in the same position as you, but have known a chap who has lived in a housing complex for about 10 or more years and used to see him three times a week and has often spoken about exactly the same problem where tenants have been asked to quieten down or they will be evicted.
The police certainly won't identify you if you do ring them, because it could have been done by numerous other tenants in the housing complex, and whether a police report is sent to housing is highly likely, then something will be done.
When these flats were built there was no consideration of any insulation between one flat and to the one next door, I know this doesn't include people making any noise outside, but this would be in the rules before they move in.
The only concern is if housing does allow you to move, you're never sure what may happen at the next flat, I know the rent is cheaper than private rental but perhaps this is something to consider, where you'll be eligible for rent assistance.
Another option is when they're asleep, turn the radio up.
Where I live, housing always says there are no available flats, but where my friend lives there are always about 6 vacant flats.
Best wishes.
Geoff.
