NHS: Assets Mr. Lansley To ask the Secretary of State for Health what the (a) gross internal floor area, (b) unoccupied internal floor area and (c) non-patient occupied internal floor area was, according to data from Estates Return Information Collection returns, for each NHS organisation in each year since 1997. Mr. Mike O'Brien The information is not available in the precise format requested. Since 2000-01, the Department has collected annual data on internal floor areas from national health service trusts through the Estates Returns Information Collection (ERIC). Data collection on each NHS organisation’s gross internal floor area and unoccupied internal floor area first began in 2000-01, with non-patient occupied floor area beginning in 2002-03. The available data for each year since 2000-01 have been placed in the Library. The information provided has been supplied by the NHS and had not been amended centrally. The accuracy and completeness of the information is the responsibility of the provider organisation.
