My neighbour in my block are subletting her housing association flat.
At first I didn't want to do anything as it didn't seem like a nice thing to do, but now the population in the flat seems to be ever more transient, and it does worry me re the security of the building.
It is also preventing someone else who may genuinely need affordable housing from accessing it, not to mention that she is probably profiting unfairly from the situation.
Reporting would be pretty straightforward.
WIBU to do it?
