Central and North West London NHS Foundation Trust

Central and North West London NHS Foundation Trust provides NHS services throughout a person’s life, in physical and mental health and everything in between, at GPs and hospitals to the community and in their own home.

CNWL is a large community facing Trust, caring for people with a wide range of physical and mental health needs in a variety of settings (hospitals, clinics, schools, homes, prisons) for every age. They are the eighth largest provider of mental health and community care in England and provide specialised services to communities outside those areas.

The majority of their services are provided in the community, which means treating people in their homes or from clinics close to home. In this sense they are a very modern part of the NHS, something the new Long Term Plan wants to see more of, with better integration and coordination of care, delivered as close to home as possible.  

They employ nearly 7,000 staff providing a range of mental health, community, learning disability, substance misuse, sexual health, dentistry and specialised services to a population of around three million in the South East of England, including in North West London, Surrey, Kent, Milton Keynes and Buckinghamshire, treating around 300,000 people either in the community or as inpatients.
