I am honestly baffled by some of the higher figures. We live in a smaller older house and don’t ration energy and last year I never paid more than £200 a month for actual usage even in the depths of winter. This year we are being more conservative with our usage but not to the extreme. We have insulated the loft, and the house had cavity wall insulation before we bought it. We have double glazing throughout and carpets and thick underlay upstairs and hard floor with rugs downstairs. Newer appliances and boiler, LED bulbs, no tumble drier, 1 TV, 1 laptop. 2 adults shower everyday and the toddler has a shallow bath. Normally turn the heating on mid October, it’s currently 18 degrees in the house without heating.
