[113424]

The performance of private sector prisons is measured through contractual performance measures and Prison Service Standards and Key Performance Targets. The Commissioner for Correctional Services will assess privately managed prisons using the same performance framework as used by the Prison Service for benchmarking public sector prisons. The results will be published at the same time.

The information requested is not available in the format requested as the occupancy of individual buildings is not recorded centrally.The previous response to the hon Member outlined the number of additional accommodation places opened at Prison Service establishments between 1 April 2001 and 31 March 2003. Of that accommodation, shown as a proportion of the current total useable operational capacity of the Prison Service estate, houseblocks represent 0.9 per cent; ready to use units 0.8 per cent and modular temporary units one per cent.

This data is provisional and subject to final end of year adjustments.
