Great Ormond Street Hospital is a world-class children’s hospital, with the broadest range of paediatric specialists under one roof anywhere in the UK. They welcome around 150,000 patient visits each year, treating patients with the most complex, life-threatening or life-limiting conditions. They are totally committed to find treatments and cures for some of the rarest and most difficult illnesses.
They rank with the small handful of truly word-class children’s hospitals in the world, providing hope to so many families.

The hospital works with the UCL Institute for Child Health, its medical school, and is the largest centre for research into childhood illness outside the United States, and a major international trainer of doctors and nurses. It has the widest range of children's specialists of any UK hospital, and is the largest centre for children's heart or brain surgery, or children with cancer, in the UK. Recent high profile breakthroughs include successful gene therapy for immune diseases, following a decade of research.

The hospital was recently rated as excellent in its care of children (one of only a handful of trusts to achieve this) and also received an excellent rating from the Healthcare Commission, which only a dozen Trusts achieved.

In 2002 Great Ormond Street commenced a redevelopment program which is budgeted at £343 million and the next phase of which is scheduled to be complete by 2012. The redevelopment is needed to expand capacity, deliver treatment in a more comfortable and modern way, and to reduce unnecessary inpatient admissions.
