The current estimated annual cost of the operation of the prison system per head of the prisoner population is approximately £34,000 on the basis of the 1992 Estimates. This corresponds to an estimated weekly cost of £660 per week.
These figures do not include any element in respect of capital expenditure. They are arrived at by taking the annual gross estimate for the Prisons Vote, as shown in the Revised Book of Estimates for 1992, deducting Appropriations-in-Aid and expenditure not connected with the running of the prisons (Probation and Welfare Service and Community Service Orders' scheme) and adding relevant costs borne on other votes (Superannuation and Teachers' salaries).
