asked the Secretary of State for the Environment if he will state the proportion of local authority housing revenue owed from rents, rate subsidy and Exchequer subsidy, respectively, and the proportion of local authority housing costs represented by maintenance, management, interest and amortisation, respectively.

The make-up of the aggregated housing revenue accounts of local authorities in England for 1976–77 is estimated as follows:

Expenditure	%
Repairs and maintenance	17
Supervision and management	13
Interest charges	61
Debt redemption	6
Other expenditure	3
	100

Income
Gross rents (dwellings)	…	53	[41]
Other rents	…	2
Exchequer subsidy	…	36	[45]
Rate fund contribution	…	7	[10]
Other income	…	2
		100

The figures in brackets are the percentages for rents net of rebates, and for Exchequer subsidy and rate fund contributions including subsidy and contribution respectively for rent rebates.
