New outpatient services are set to be introduced at St Mark's Hospital in Maidenhead after moving from their current base at Heatherwood Hospital.
Treatment for eating disorders, complex needs and psychotherapy will move from the Ascot-based hospital to the community health clinic at St Mark's, in St Mark's Road, by the end of January.
A spokeswoman for the Berkshire Healthcare NHS Foundation Trust (BHFT), which runs the services, has also confirmed the future use of the recently-closed Charles Ward is still to be decided.
The mental health ward closed on Thursday, January 9, with patients transferring to Prospect Park Hospital in Reading.
The spokeswoman added no further services were due to move away from the hospital.
