To mark the occasion, a few sobering statistics.
One-quarter of households in England headed by parents aged 16-24 years live in fuel poverty; this affects 3.8 million children.
1.14 million older people in England live in fuel poverty; in the winter 2014/15, some 31000 ‘excess winter deaths’ were reported in England and Wales, most occurring people aged 75 and over.
Households living in rental accommodations have the highest rates of fuel poverty, reflecting poor upkeep by landlords.
In the two lowest income 'deciles' - i.e. the 20% of people in the UK with the lowest incomes - up to 40% of people live in fuel poverty.
