Since April 2006, commissioning responsibility for prison health services has been fully devolved to the national health service.
Funding for health services, including mental health in-reach, is therefore allocated to those primary care trusts which contain prisons in their areas.
In total, 102 mental health in-reach teams operate within prisons, including young offenders institutions, and their services are available across the entire prison estate. Since 2005-06, £20 million has been invested in these services each year.
