When I visited England, many homes did not have central heating. The heaters were coin-operated. The poor might run out of money to heat their homes. That might be why there was much higher excess mortality in the winter months. I don’t know if that is still the case or whether the poor are aided with heating costs as they are in some areas of the U.S.
Plus, the U.K. had very few excess heat days compared with excess cold days.
