Last winter, I sat in a small cottage in Derbyshire with a retired schoolteacher named Mary Jenkins.
She greeted me wearing two jumpers and fingerless gloves. …inside her own living room.
Her thermostat read 15°C.
“I keep it low to save money,” she said, embarrassed. “Otherwise, the bill gets too high.”
Her last statement showed £340 for a single month! Nearly double what she paid the year before.
Same cottage. Same usage. Same supplier.
