To ask the Scottish Executive what information it has on average household expenditure on (a) gas and (b) electricity bills in each year since 1960 as a proportion of average household incomes.
The Scottish House Condition Survey provides survey estimates of household gas and electricity expenditure for the years 1996, 2002, 2003-04, 2004-05 and 2005-06.
The Department for Business Enterprise and Regulatory Reform provides data for Scotland going back to 1990 for gas and electricity expenditure but only broken down by payment method – with no total.

The same Departmental site also provides UK expenditure on domestic electricity and gas going back to 1974 (Table 2.6.2 Average Expenditure Each Week on Fuel per Consuming Household). A comparison of levels of expenditure in Scotland and the UK can be made where statistics exist from both data sources for a particular year.
From the average ratio of these comparisons, the average annual domestic expenditure on (a) gas and (b) electricity can be constructed for Scotland back to 1974.
“Average” household income figures are very skewed by high income earners. Their incomes distort the average household income figure. Therefore the “Median” household income is the preferred central measure. It is available for Scotland from the Department of Work and Pensions Households Below Average Income data series for the period 1994-95 to 2006-07.
Therefore, on a consistent basis, using median household disposable income, the proportion of household income spent on (a) gas and (b) electricity is available for the period 1994-95 to 2006-07. The figures for these measures are shown in the following table.
