I live in a building in Central London (Soho) that has 12 flats. We pay market rate for ours, that is supposed to help the housing association offset the cost of some of the other flats that are designated as social housing.

Most of these flats are just constantly churning Airbnb guests in and out, some of the others have lodgers (also illegal, friend of mine lived in one of them, hence why I know).

I don't know what to do with this information, but its such a shame that people are so comfortably scamming the government, when it's literally funded by all of us.

EDIT: per the responses, I have called the council and they were very keen/interested. Thanks for your input.
