Partnerships in Care (PiC) has agreed to acquire Care UK’s mental health services that includes 323 beds, allowing it to expand services in mental health rehabilitation.
Terms of the deal have not been disclosed.
PiC group chief executive Joy Chamberlain said: "I am delighted with the addition of these units to PiC’s portfolio and our expansion into child and adolescent services.
"We look forward to bringing PiC’s expertise to providing high-quality services for young people and adults with mental health needs, and welcoming new colleagues to the PiC family."
Chamberlain noted the group recently added 500 new beds with the acquisition of Pastoral Healthcare, Vista Hospital and two units from Choice Lifestyle.
According to PiC, the deal is expected to be completed in June 2015.
Care UK chief executive Mike Parish said: "Care UK has developed market leading positions in health and social care and is well placed to further enhance services to the benefit of its customers, patients and service users."
Claimed to be one of the largest mental health service providers in the UK, PiC will now include 1,800 beds.
Care UK is a provider of elective surgery free at point-of-use for NHS patients through ten NHS treatment centres, and is currently focusing on the development of primary and secondary NHS health services, as well as residential care services.
