The trust, which has been rated “good” serves people in the boroughs of Hounslow, Hammersmith and Fulham and Ealing.
The inspection was carried out in response to information received and concerns found in the last inspection.
The CQC looked at the trust’s Mental Health phone triage service and two crisis assessment and treatment teams based in the community.
They support people over 18 years old in mental health crisis or those needing intensive home-based support.
Inspectors did not re-rate the service following this latest inspection.
They found people using the service felt listened to and involved in their care and staff were understanding, calm and caring.
But, the report also found some patients in the Hounslow CATT did not have safety or crisis plans in place.
Dr Christopher Hilton, Chief Operating Officer for Local and Specialist Services at West London NHS Trust, said:
“We’re pleased to have retained our overall rating of ‘Good’ following this latest announced focused inspection from the CQC, relating to our mental health single point of access (SPA) service and crisis assessment treatment teams (CATTs).
“The feedback from the report was that service users felt listened to and found our staff supportive, caring and understanding and we were pleased that the inspectors commented favourably on examples of learning, improvement and innovation.
“We welcome this feedback and will be working rapidly to address the recommendations, as we aim to offer the highest quality of services to the communities of West London.”
