The trust gained Foundation trust status in May 2016.

Development
The Trust opened a new hospital, Clock View Hospital in Walton in 2014. It has a psychiatric intensive care unit for people who need intensive short-term treatment and assessment.

It took over Calderstones Partnership NHS Foundation Trust which had a turnover of £42 million per year in 2015. About 130 patients from the Calderstones site had been into alternative services by 2019. It planned to move patients with "exceptionally complex mental health disorders" to a new 40-bed low-security unit in Maghull, but has been unable to secure capital funding.

In 2016 it took over the former Walton Carnegie library in order to set up a new centre for learning, recovery, health and wellbeing.

It acquired the failed Liverpool Community Health NHS Trust in increments over 2017/2018.

The trust was one of the beneficiaries of Boris Johnson's announcement of capital funding for the NHS in August 2019, with an allocation of £33 million for a new 40 bed low secure unit for people with learning disabilities.

In November 2019 it was reported that the trust was to take over North West Boroughs Healthcare NHS Foundation Trust.

It started a COVID Oximetry@Home service in April 2020. This enables monitoring of more than 5000 patients a day in their own homes. The technology, provided by digital health company, Docobo, allows nurses, carers, or patients to record and monitor vital signs such as blood oxygen levels.

493 patients were injured in 2016-17 through use of restraints on psychiatric patients in Merseycare NHS Foundation Trust.
