I don't know anything about this housing benefit.
Why do they get it, when I first got married, after serving in the RAF I had to pay own own rent, and then further down the line our own mortgage until it was paid up.
The ironic thing now though, is the fact that my house doesn't really belong to me or my wife, because if we have to go in a home, they will take my house to pay for our keep.
This country certainly looks after you, unless of course you happen to have been born here, served your country, and paid your taxes all your working life.
