The Office for National Statistics provides information on health spending, including private spending on health care up until 2002, on its website (http://www.statistics.gov.uk/healthaccounts/experimental.asp). The ONS series on private health spending is now discontinued.
Internal Treasury estimates for later years, based on a number of assumptions for discontinued data series, are in the following table.
