We live in central London in an apartment block. The owner of the flat above us gave a mandate to a man who finds short lets for city bachelor parties. Once we cottoned on to what was happening, we told the owner that it was not in the contract to sublet the flat like this and therefore illegal. He told us he would try and sort it out and we gave him a deadline before we would notify the freeholder.
Months later they are still hosting
weekly bachelor parties starting on a Thursday night and leaving on Sunday. They are always drunk and loud (we have young DC,) they fight in the common parts and crash around upstairs, we have had water coming through the ceiling twice due to them leaving the bath running and passing out, found drug paraphernalia, vomit in the common parts and have been kept awake at all hours by shouting, swearing, doors banging, loud music etc.
We have called the police but they have said it is not their concern.
We contacted the flat owner and he has said that the subletter has now "gone rogue" with his access to the flat and is subletting it against their wishes and they cannot control him from afar (they are based in Switzerland) and have too many other properties to manage.
We contacted the freeholder who sent a warning letter to the owner in Switzerland, but got their letter returned telling them that the address did not exist.
What has to happen now? And what do the bachelor parties have to do for the police to take action?
