To ask the Secretary of State for Communities and Local Government what effect the conversion of a house in multiple occupation to a single dwelling has on the calculation of the number of housing units under the criteria used to assess housing levels (a) nationally and (b) under the housing target in the London Plan. (321349)

The conversion of a house in multiple occupation to a single dwelling would have no effect on the estimate of dwelling numbers nationally. This is because a house in multiple occupation is counted as one dwelling.

The housing numbers in the Mayor's London Plan include “non self-contained” accommodation. In London, therefore, conversion of a house in multiple occupation would result in a reduction in “non self-contained” accommodation.
