Poverty is relative, but as gillybob said in her post, meters are fitted for those unable to pay resulting in cold and hardship for those in difficulty as they then have to pay more for their fuel.
If they get into difficulty with their bank account that can be a downward spiral, bank charges can get out of control so those in most difficulty are penalised again.
Most people would always put their children first and go without themselves, but not everyone unfortunately.
Many women did not go out to work in the 50s and 60s, my MIL was widowed during the war but did not go out to work, I don't know how she managed but she did. My DM worked part-time but still managed to knit, sew, cook meals from scratch etc, my DP were really hard up but I always had decent shoes and warm clothes as did my brothers.
