Vacant stock at district level is collected from a variety of sources:
The number of local authority owned vacant dwellings and the number of 'other public sector' (other than local authority and RSL) vacant dwellings is obtained from the Housing Strategy Statistical Appendix (HSSA) and the HRA Business Planning Statistical Appendix (BPSA) submitted to CLG by local authorities.
An estimate of the number of private sector vacant dwellings is obtained by subtracting the number of local authority owned, RSL owned and 'other public sector' vacant dwellings from the total number of vacant dwellings obtained from council tax records submitted to CLG by local authorities on CTB1 and CTBS1 returns.
Figures on council tax vacants can be found at
http://www.local.communities.gov.uk/finance/stats/ctbase.htm, and data on stock and vacants for local authorities and RSLs can be found at
At regional level, additional information on the age, type and condition of vacant stock is available from the "English House Condition Survey" (EHCS).
