I think most people will be able to make savings on energy. Things such as turn the heating down, not put it on until November, buy a slow cooker, get thicker curtains, an electric blanket and other measures that involve a small outlay. It will still cost more but I think energy use in homes this winter will drop. Any new appliances people buy will most likely be the most energy efficient .
The people who are really stuffed are the ones who already have no reserves to get the slow cooker, or who already hardly have the heating on and they are probably in the poorest quality housing with the most inefficient insulation, heating, hot water and appliances.
there used to be home improvement grants for new boilers, double glazing, insulation etc but not anymore
