Around half of all children in the UK from separated families are being brought up in poverty. In 2010-11 the Child Maintenance and Enforcement Commission collected and transferred £1.1 billion to parents caring for more than 880,000 children. Nevertheless significant, all too familiar and recurring challenges remain: parents are frustrated with the standard of support received from the Commission. Maintenance payments totalling some £3.7 billion are outstanding, but the Commission estimates that only £1 billion of this is collectable; and costs remain high. The Commission also faces further significant challenges in introducing its new child maintenance scheme. In particular, it will need to respond to substantial cost reductions and successfully implement a new system of charging fees to parents who choose to use the Commission's services. The Commission needs to deliver acceptable standards of service at a reasonable cost. The new child maintenance scheme should improve efficiency, but further changes are needed to streamline existing processes. The Commission has to deliver cost reductions of £117 million by 2014-15 and its plans are currently £16 million short of this target. Its cost reduction plans depend in part on a new IT system which is already late. To meet the current timetable critical testing will have to be undertaken in parallel with development work, mirroring poor practices that have contributed to the failure of a number of government IT projects. Each month of delay will increase the Commission's costs by at least £3 million and may delay planned income from fees.
