From Monday 27 January, people in North West London experiencing a mental health crisis can access CNWL’s Mental Health Crisis Assessment Service on a walk-in basis, with no referral needed.


Further details about the service and its location are provided below.

The Mental Health Crisis Assessment Service (MHCAS) offers a calm and therapeutic mental health setting to treat the majority of emergency mental health presentations.

We see and assess anyone over 18 years old that would otherwise go to an emergency department for mental health reasons and does not have an urgent medical need (for example, an overdose of medication).

We offer full emergency mental health assessments and onward care planning in the department with a diverse and highly skilled mental health workforce incorporating nurses, doctors, support workers and access to drug and alcohol workers and psychology.

We can support every aspect of emergency mental health care planning from GP referrals to Mental Health Act Assessments.

People who have attended an Accident and Emergency (A&E) department within Kensington and Chelsea, Westminster, Brent, Harrow or Hillingdon or are a resident of these boroughs and in another A&E, as long as there are no urgent medical needs.

Referrals will be made through the A&Es Liaison Psychiatry Team who will complete an initial assessment first.

Residents in Kensington and Chelsea, Westminster, Brent, Harrow or Hillingdon who have not attended A&E but are going through a mental health crisis can also use this service. 

A&E Departments:

  • Referrals will be made through the A&Es Liaison Psychiatry Team who will complete an initial assessment first.

First Responders (for example, ambulance and police) and other mental health teams:

  • Ambulances, police and other mental health teams can also refer through SPA on 0800 0234 650 - if assessment at MHCAS is needed then they can bring people straight to our door.

Self-referrals for people going through a mental health crisis:

  • People in mental health crisis are able to walk-in to MHCAS without having a referral.
  • As a first point of call current patients can contact their usual community mental health team or telephone our 24/7 single point of access (SPA) line as usual on 0800 0234 650.
  • If unsure of whether MHCAS is the right service for you, your community mental health team or SPA can direct you here or advise whether your needs are better met elsewhere.

The Mental Health Crisis Assessment Service is open 24 hours a day, seven days a week
