An Energy Trends special feature article published by BEIS on Monday 15 April has found that the theoretical fuel expenditure derived from fuel poverty statistics is, on average, £133 higher than the actual consumption recorded in the National Energy Efficiency Data Framework for English dwellings, or 9.9% in percentage terms. This average cost difference increases to £319 for fuel-poor households (19.9%) while for non-fuel-poor households this difference decreases to £110 (8.6%). BEIS concluded that the gap between theoretical and actual energy consumption is negatively correlated with income, with the households in the highest tenth for incomes using on average £27 more than the theoretical consumption and those in the lowest income decile using on average £189 less.
