What we do

What we do

Graphic showing CQC assessment as GoodWe are commissioned to support adults with a learning disability who require treatment in specialist and secure services, including offenders, those who present with extremes of challenging behaviour, people who present a significant danger or have complex needs that cannot be met by local services. 

Our services are designed to ensure that, where possible, the service user can move back into the community at the right time and that they can benefit from a better quality of life than before they came to Calderstones. In 2016 the Care Quality Commission assessed Calderstones as 'Good' across all domains.

We understand that people’s requirements are very different. We have highly skilled staff and the majority of our wards are state of the art 21st century-built accommodation. Combining this with our community and on-site services means that we can provide a care package for adults who cannot be supported by other organisations. The number of occupied beds across the Trust at the end of January 2015 was 202, with about 95% detained under the Mental Health Act. Just under 100 service users are in low secure settings, we support over 50 in medium secure units and the majority of the remainder are in our enhanced or step down services as they prepare to move on from us.

You can view our locations in detail on this page.

The Trust is also internationally regarded for its research and development function. Until 2016 we also delivered financial services nationally to over 20 NHS organisations.

Our secure services are listed below. We do not provide High Secure Services:

Medium Secure Services

The Woodview and Gisburn Lodge services provide support for people with a learning disability who are detained within a medium secure setting. These units were built in the last decade.

Low Secure Services

Our West Drive and Maplewood premises provide support to people with learning disabilities who need treatment and care in a low secure setting.  Maplewood was built in 2001 and extended in 2013 and West Drive was refurbished in 2015.

Step Down Services

Services for people on care pathways progressing from a low secure setting are provided in our premises in Whalley.

Enhanced Services

Certain parts of the Trust including Scott House in Rochdale and houses in Lancaster help people move through the service before they are able to live with support in community settings. The Trust also has several houses near our Whalley site that are used to help people prepare to live in their own homes. 

Forensic Support Service

We also deliver a Forensic Support Service to Lancashire and Greater Manchester. This service aims to prevent the admission or re-admission to secure services and provides support and advice to local learning disability services in helping to look after forensic service users in the community and stop future admissions. With support from the North of England Specialist Commissioning Group, the Forensic Support Service is running a prison in-reach programme and working with Lancashire Constabulary on improving management of people with a learning disability.


The Trust has a significant reputation for the quality of its research into learning disability and offending behaviour. Experts speak at conferences and author papers and we have an ongoing series of research programmes, many of which involve our service users as active participants and even as trainers. The Trust has close links with a number of major academic establishments and it sponsors specialist LD events.


Further information from the DoH

What are secure mental health services?

Secure mental health services are specialist services providing treatment for adults with mental disorders including personality disorders that mean that they are at significant risk of harming themselves or others. Patients are detained under the Mental Health Act 1983 and many, but not all, will be convicted offenders.

What does ‘secure’ mean?

In this context ‘secure’ relates to the range of physical, relational and procedural measures put in place to ensure the provision of a safe and secure environment in which to deliver treatment. There are three levels of secure care; high, medium and low. There is guidance governing provision at each level. Depending on individual needs, patients may go through an integrated care and treatment pathway that spans one or more levels of care.

The purpose of security measures is to ensure the safety of patients and the public, to prevent escape and absconding and reduce the likelihood of patients failing to return from agreed periods of leave. It is important to understand the differences between these three events.

High secure services (not provided by Calderstones)

At present, DH’s relationship with high secure hospitals is different to the relationship to any other NHS service as the NHS Act 2006 places a specific duty on the Secretary of State for Health to provide high secure hospital services. Patients in high secure hospitals present a grave and immediate danger to the public and require a significant period of treatment.

Medium secure services

Medium secure services are provided by a range of NHS and independent sector organisations, and are for people who present a significant danger. Many patients will have a history of offending and some will have been transferred from prison or from court to receive inpatient treatment. Typically, patients will remain in treatment for between 2 and 5 years.

Low secure services

Low secure services are for people detained under the Mental Health Act who because of the level of risk or challenge they present cannot be treated in open mental health settings. Services are provided by a range of independent sector organisations and NHS Trusts. Patients may have a history of offending and may have been transferred from prison or courts to receive inpatient treatment.
