How do you live in the UK without participating in interest?

Q: My question pertains to interest which I know is forbidden in Islam and is seen as a great sin. But in the UK, through mortgages, insurances, etc., it seems virtually impossible to avoid riba (interest). I have looked into Islamic banking in the UK but I see it to be an awful alternative as it still essentially charges riba but with some clever play on words and has been dismissed by the consensus of scholars. So my question is: how do you live in the UK without participating in interest as I am struggling to see alternatives?

Inheritance Question

Q: The executors of my father have sold some land belonging to father and his siblings. We have received part payment of the amount of the sale.There is however a court case  regarding  three other parties concerning the sale of the land.We  are unsure of the cost of the court case or how long it will take.Is it permissible to hold back the monies until the court case is over and paid for and then distribute the shares according to Shariah because these days it is difficult to get money from the inheritors once they receive it.
