Oh Thierry. I'm so very sorry. Still hoping against hope for good news for you. 
As for you, user123456 or whoever you are - I can't figure out if you are goady or extremely naive, but how on earth can you think 'very very wealthy' people live in £250,000 flats? In London?? It beggars belief. I know that that is utterly laughable, and I live on the other side of the planet.
Stop trying to pretend that this tragic event, and the way it'll play out over the next few months and years, is not at least partially about class and low socioeconomic status. It's offensive and dangerous.
Tenants do not get a say over who does work in their home. When an HA gives a tender to a company that company sees the HA as the customer NOT the tenant.
HelenaDove speaks a lot of sense.
Most of the people who live in these types of buildings get very little say over their living conditions. They have no leverage as they don't own anything, they don't have money to give kickbacks to their powerful mates in construction and local government (and don't have any powerful mates anyway), they didn't go to school with any politicians, many of them speak English as a second language, they don't have the level of education required to mount an articulate, compelling argument against the HA and their lawyer cronies, they can't afford any legal representation and oh, Legal Aid is too busy, come back later...the list goes on.
And on top of all that, they can't just pick up their families and move because hey, they're living in a city with (arguably) the biggest housing crisis on the planet. There is literally nowhere else to go, and certainly nowhere else close enough to allow them to keep their jobs, and keep their children in the same schools.
So they battle on, and try not to think about the fact that they, and their children, are living in a death trap. Because they just don't have an alternative.
Do you really think, user123456, that this is how life is for 'very very wealthy' individuals? Do you really think that what has happened to these poor people could just as easily have happened in a building full of High Net Worth individuals?
That is an insult to the people who have lost their lives in this absolute horror. Shame on you.
