A large number of services, such as cardiothoracic medicine and surgery, neurosciences and renal transplantation, also cover significant populations from Surrey and Sussex, totalling about 3.5 million people.
It shares its main hospital site in Tooting, England with the renowned St George's, University of London which trains NHS staff and carries out advanced medical research.
St George's Hospital also provides care for patients from a larger catchment area in the South East of England, for specialties such as complex pelvic trauma.
Other services treat patients from all over the country, such as family HIV care and bone marrow transplantation for non-cancer diseases.
St John's Therapy Centre was officially opened on Thursday 2 July 2009 by Professor Ann Keen MP, Parliamentary Undersecretary of State for Health.
A modern flexible building, the new centre is much larger than its predecessor and allows patients to access a variety of services under one roof.
St George's Healthcare was named 2009 Large Trust of the Year by the independent Dr Foster Intelligence, publisher of the Hospital Guide.
[7] In 2009/10 St George's Healthcare achieved a surplus on income and expenditure of £10.6m meeting its financial duty to break-even during the year.
With regard to its other financial duties, the trust stayed within its external financing limit (EFL) – using slightly less cash to fund its services and to meet its obligations than the allowance set by the Department of Health.
The trust also met its capital cost absorption duty earning a return of at least 3.5 per cent on its assets (land, buildings, equipment etc.)
[11] In April 2017 it submitted a request for £200 million to improve its buildings after the Care Quality Commission warned it about breaches in regulations related to safe and fit premises.
[19] In the summer of 2015 immigration officers from the Border Force were stationed in the hospital to train staff to identify "potentially chargeable patients".
[20] In October 2016 the trust announced that it planned to require photo identity papers or proof of their right to remain in the UK such as asylum status or a visa for pregnant women.
