Coronavirus update: the way we provide some of our services will be changing during the COVID-19 pandemic. For inpatient services like our low-secure hospital service (Kedleston Unit), we are following national guidance about changes to visiting - please see the visiting times page on this site for more details. Thank you in advance for your understanding at this time. 

people sitting waitingWe provide several mental health services to support people within the criminal justice system or those who are convicted of a criminal offence.

The criminal justice liaison and diversion team provides an innovative screening service available at several points within the criminal justice system. This allows early detection and assessment of offenders with mental health, learning disability, substance misuse or other vulnerabilities, to ensure appropriate and effective outcomes.

NHS England has invested extra funding in order to create this full liaison and diversion team, serving people of all ages and all vulnerabilities. Learn more on the NHS England website.

Who does the team support?

The service is aimed at those who come into contact with the criminal justice system because they have committed, or are suspected of committing, a criminal offence and: 

  • may be acutely or chronically mentally ill and need to be assessed under the Mental Health Act
  • may have neuroses, behavioural and/or personality disorder
  • have a history of contact with mental health services
  • have a learning disability
  • have an issue with substance misuse
  • have other relevant vulnerabilities.

How does the team operate?

The criminal justice mental health team assesses people in police custody at Derby, Chesterfield and Buxton police stations, magistrates courts in Derby and Chesterfield, and Derbyshire probation services. It also works with youth offending teams.

The team carries out screening to identify whether an individual has vulnerabilities. They will then support vulnerable individuals to access their first appointment and begin the process of giving them advice to improve their health outcomes and reduce their chances of re-offending. That advice could be about direct health-related matters or issues like housing or finance.

The team also provides a prompt response to concerns raised by police and the courts. It can provide key information without unnecessary delay to help police and courts when charging and sentencing vulnerable people.

It can also act as a point of referral for service users to make sure that they know about treatment and rehabilitation appointments.

In particular, the team specialises in community sentence treatment requirements - learn more on the community sentence treatment requirements page.

Where is the team based?

The team is based at three locations - one in Chesterfield and two in Derby. Across those three bases there are teams of nurses and engagement workers.

How do I contact the team?

The team can be contacted by calling 01332 268490.

Our team at the Kedleston Unit provides a gender-specific low-secure service for males.

The team delivers intensive, comprehensive, multidisciplinary treatments and care for patients who demonstrate disturbed behaviour in the context of a serious mental disorder and must be in a secure setting.

The service is commissioned by NHS England. Referrals come from regional medium-secure units, prisons, Ministry of Justice recalls and acute adult wards. There are 20 beds at the Kedleston Unit: Curzon ward is an eight-bedded assessment ward and Scarsdale ward is a 12-bedded rehabilitation ward.

Referral criteria

  • Males 18 years and above
  • Must be suffering from a mental disorder, and detained under the MHA 1983 (not section 2)
  • Must require treatment in a specialist low-secure service
  • Will usually have complex and challenging forensic and mental health needs.

External referrals should be addressed to Referral Panel, The Kedleston Unit, Kingsway Hospital Site, Derby DE22 3LZ or sent to the secure email address

The Kedleston Unit team are members of the Royal College of Psychiatrists' Forensic Quality Network. They are active members in service review and sharing of good practice through the network.

In 2019 we have introduced a new community-based forensic service. This service provides a community focus for supporting people who have committed a criminal offence while mentally unwell.

What does the service do?

The service's priority is on meeting statutory (legal) responsibilities, care and treatment for individuals. Many, but not all, of the service users are individuals detained under the Forensic sections of the Mental Health Act.

The team offer support, advice and assessment to people where concerns are raised in regards to risk behaviours associated with mental illness. This can include our own services, prisons, police, probation and the courts.

What types of health professionals are part of the team?

The service provides focused support led by a small, dedicated team consisting of four nurses and a forensic psychiatrist.

The team will provide specialist forensic support for individuals who would previously have been seen through the Trust’s neighbourhood teams.
