To ask the Secretary of State for Communities and Local Government how many houses in each local authority area have cavity wall insulation. (89341)

My Department does not collect information for each local authority on these details. The 2004 English House Condition Survey provides the following figures for England: there were 15,042 dwellings (70 per cent. of all dwellings) of cavity wall construction, of which 5,835 (39 per cent. of all dwellings with cavity walls) were insulated.
