I completely disagree. You can't just make a blanket statement that anyone spending £90-100 a week has not already done quite a bit to combat energy costs. Some households don't just have 2 people living there. There are large families with multiple children in a lot of houses. When every light in your house is LED, you use smart plugs everywhere on schedules, minimize and strategize washing/dishwashing/heating usage etc etc.... there really does come a point where you can't realistically chase much more of a reduction without it becoming an obsession that is unlikely to yield much of a difference if you want to maintain a fairly normal standard of living.
... Sometimes I wonder how my mind works
