Father's visa on Humanitarian Grounds

[fabio11]

Hi guys,
My father si visiting me on multiple entry visit visa. I have indefinite leave to remain here. In our home country my father
1- has no finanical connections in terms of property or bank balance.
2- He is financially dependent on me.
3- My mothers has paased away and my siblings are married and not able to keep him with them.

I want to apply for his permanent stay visa while he is here on visit visa.
Can someone please guide me about the procedure, fees, time it takes to get an answer (as he can only stay 6 months here on visit visa) and where to apply?

Many thanks in advance.
