The cost of a prisoner on remand in custody is not separately calculated.
The estimated average annual overall cost per prisoner in England and Wales for financial year 2010-11 is £37,000 (to nearest £1,000). These are the latest figures.
Average prisoner costs are calculated for each prison establishment and grouped by prison function on the basis of the major use of each prison. The calculations do not analyse costs by type of sentence or prisoner, and therefore, an average cost for a prisoner serving remand is not available.
The annual average cost per prisoner equates to an average cost per day of £102. This is across all prisoner types and lengths of custody. This does not represent the marginal cost (or saving) from spending one day more (or less) in prison, as most prison costs are fixed in the short-term. Nor should it be used to calculate the cost of a particular term in custody as costs are not necessarily incurred evenly across a period of custody.
A predominantly, large number of remand sentences are served in local adult male prisons. The estimated average overall annual cost per prisoner in local adult male prisons for financial year 2010-11 is £35,000 (to nearest £1,000).
The calculation for cost per prisoner is based on net resource expenditure related to prisons included in the annual accounts of the National Offender Management Service (NOMS) expressed in terms of the average prison population. This includes some estimation. Expenditure which is met by other Government Departments, such as expenditure on health and education, is not included. Expenditure recharged to the Youth Justice Board in respect of young people is included.
