People keep responding to those worrying about energy costs, don't worry, homes never used to have heating, people survived, just don't put your heating on!
Home did not have central heating. Instead, they had fires and heated individual homes. People did not live in homes with no heating in the UK.
In the UK during the winter if a home is never heated even by late November /December temperatures inside will have gradually dropped to a temperature that's too low.

There is a huge difference if you even use your heating for just 1hr a day, topping up the temperature to stop it dropping so rapidly.
People need to stop acting as though those struggling just need to toughen up, 'wear more layers' and cope with the heating off this winter as a solution to energy costs, as it's simply not feasible, and it would be better for people to take action now to let their energy provider know they are in fuel poverty and need to access help.
