Thanks !
No, I didn't ask for it to be reviewed. I am not even sure I would have the right, to.
It was a long time ago, and I do not fully remember .. but the reasons they gave in the rejection letter, were basically something like : your housing situation is not the one to pose any health hazard, or a potential health hazard, or anti sanitary conditions ... and your living space available to you (in my present flat) is not limited enough, or small enough [presumably to necessitate granting me another accommodation]. Regarding the space available for my use, in my present flat - that they must have judged from my answers to questions in the application form. Those were basically the main reasons. Plus .. they may possibly have added something like ... the social housing availability is very limited .. and they can only provide social housing to people in greatest need or most suitable circumstances. Or maybe that was what I read before.
Me explaining to them, in the application form, that - once my immediate family leave the city or the country, I will basically have nowhere to live in this country, or no readily available accommodation (or something along those lines) - obviously had not had a decisive or radical effect.
As to the Citizens Advice Bureau - no, I do not think I spoke to them regarding an application. Thanks for the advice though. However, earlier in time, about 2012, I did speak to one adviser regarding social housing and applying for the Housing Register. From my conversation with that lady, it was clear that my chances of being granted any FREE accommodation, are somewhat slim. ''You are a young, healthy male'' - she told me. I was then 29. But applied for the Housing Register at 32, I think.
Either that lady, or the rejection letter I received in about 2015, mentioned the concept of Shared Accommodation (presumably as one of the options available in my situation). But shared accommodation, as far as I understand, is not something totally for free. I would have to pay.
