People who are made redundant are usually entitled, after a period of time, to payment of interest on their mortgage loans. Their homes are a very valuable asset, not because they have worked harder or been more frugal than people who rent, but because there is a shortage of housing, from which they have benefited but which has adversely affected renters.
Ana You say: "but they [homeowners] aren't taking up social housing and are probably paying a lot for council tax, heating and maintenance of those homes. No free repairs and redecoration for them!" As I've said before, people in private rented accommodation are legally entitled to have internal and external repairs carried out by their landlord. In the same way, because a council property belongs to the council, it is the council's responsibility to maintain it. If you carry out repairs and redecorations to the home you own, you bear the cost but you are also maintaining, and often increasing, the value of that home.
Also, most people pay council tax and those that are exempt include homeowners too. And, of course, council house tenants have have to pay for their water and energy bills just like anyone else.
I don't agree with the no spare room rule - whether it be applied in the case of pensioners or families. However, I believe the Conservative government exempted pensioners for political reasons - not because they were being especially kind-hearted.
