Circle Health

Circle Health Group is a private healthcare provider in the United Kingdom, and is the country's biggest private hospital provider. The company was founded in 2004 and rebranded as Circle Health Group in 2019 after acquiring a rival, BMI Healthcare; in the same year it began an expansion in China. In 2023 the company was acquired by an Abu Dhabi-based holding company called PureHealth.

Circle Health ran an independent sector treatment centre delivering dermatology services in Nottingham from 2008 until 2019, at which point the operation of dermatology services was returned to Nottingham University Hospitals NHS Trust. The operation of dermatology services during the period in which they were run by Circle Health was described as an "unmitigated disaster" in an independent report commissioned by the local clinical commissioning group which runs health services in the county.

In November 2011 the company was awarded a contract to run Hinchingbrooke Hospital in Cambridgeshire, the first NHS England hospital to be operated by a private company. Circle Health withdrew from the hospital, three years into the ten-year contract, shortly after being severely criticised by the Care Quality Commission (CQC) over standards of care and hygiene. The CQC report indicated that "Medical services were inadequate because we found poor emotional and physical care which was not safe or caring. This was not reported by leaders of the service to the trust management therefore we judged the leadership to be inadequate." It was the worst rating for 'caring' that the CQC had ever given. Circle Health left the hospital with a £14 million deficit that, because Circle had limited its liability to £5 million, the taxpayer had to pay for.
