§ Mr. Welsh
To ask the Secretary of State for the Environment, Transport and the Regions what is the average energy efficiency rating for housing in England; and if he will provide a breakdown by(a) local authority, (b) private sector and (c) housing association dwelling, on the latest available estimates. 
§ Mr. Raynsford
The latest available estimates (from the 1991 English House Condition Survey) show the average energy efficiency rating for occupied housing in England to be 35, measured on the Government's Standard Assessment Procedure. The average SAP ratings of local authority, private sector and housing association dwellings are 34, 36 and 35 respectively. The figure for private sector dwellings reflects an average of 37 for owner occupied and 22 for private rented dwellings.
