Its flagship hospital is the Priory Hospital, Roehampton, which is best known for treating celebrities particularly for drug addiction.

In October 2014 Riall announced that the group was planning a significant expansion into the mental health community services market and would bid in partnership with “incumbent” NHS providers, an approach that would allow them to come up with new models of care. He expected more services to be put out to tender by Clinical commissioning groups. Priory could contribute their "considerable commercial bidding expertise”. Riall wants Priory to be the “overflow provider of choice” for the NHS.
Acadia Healthcare bought the business for £1.3 billion in January 2016.
