I don't agree at all with your drift, OP. I don't know where you're coming from: e.g., perhaps, paying £50 per week for gas in winter, and with an amazing draught-free, insulated house - and feeling great in the winter months, but many people would struggle even to find £20 per week, during the winter months.
Some posters have said, on this forum, that they are on a very tight budget. The price rise will really hit them. I met an acquaintance I know, last month, who had no gas or elec at all at home - I gave her £50.
I find, during cold months, that when that has goes off for six hours, I am absolutely freezing, and it doesn't seem as though the heat which was being generated has been stored. Even with jumpers on, the air feels unhealthy. . It just goes to aching bones- freezing....and the hot water bottle seems to cool down again, very rapidly.
Some people will struggle. Some people really feel the cold.
As far as I'm aware, our ancestors would light hearth fires; there would be some braziers in the street; people helped out others; poor people shared houses. You could burn anything, and nobody would complain - hardly. Few of these Victorian remedies exist, for many people; people will just be too cold to think, won't get their washed clothes dry, and will suffer and get ill.
