Five worth knowing.
A service-based editorial selection covering broad acute care, cancer, children’s care and heart/lung specialisms. The numbering is not a clinical quality, safety or waiting-time ranking. These hospitals serve different patients and cannot be compared as interchangeable alternatives.
For a life-threatening emergency call 999. For urgent help that is not life-threatening, use NHS 111. Do not delay urgent care to travel to a hospital on this list.
- Lambeth · beside Westminster Bridge
St Thomas’ Hospital
NHS · broad acute careA major central London hospital
St Thomas’ provides broad hospital services and has an emergency department. It is included as a major central London acute-care site, with the important distinction that Guy’s and St Thomas’ are separate hospital locations within the same trust.
Before you decideUse the site and department named in your appointment. A trust’s familiar name is not enough to identify the right entrance or service.
- Euston Road · central London
University College Hospital
NHS · acute and specialist servicesCare across a wider hospital network
University College Hospital is part of UCLH, whose hospital network includes substantial specialist services. Its cancer provision includes the Macmillan Cancer Centre and the Grafton Way Building; care may take place in different buildings.
Before you decideRead the building as well as the hospital name on the appointment letter. UCLH is a trust, not a single doorway, and service access depends on the relevant referral route.
- Chelsea and Sutton
The Royal Marsden
NHS specialist · cancer careA specialist cancer-care option
The Royal Marsden is a specialist cancer hospital with Chelsea and Sutton sites. Its patient information covers cancer diagnosis, treatment and support, while the Oak Cancer Centre in Sutton combines research and treatment facilities.
Before you decideDiscuss suitability with your treating team. Confirm the exact site and referral arrangements; specialist reputation does not make it the right service for every medical problem.
- Bloomsbury
Great Ormond Street Hospital
NHS specialist · childrenComplex specialist children’s care
GOSH provides specialist paediatric services, with published referral pathways and clinical specialties. It belongs on this list for its specialist role in children’s care, rather than as a substitute for ordinary local services.
Before you decideUse the referral pathway for the specialty involved. An online shortlist is not a referral, and a planned specialist appointment is different from seeking urgent help.
- Chelsea
Royal Brompton Hospital
NHS specialist · heart and lungsSpecialist cardiology and respiratory care
Royal Brompton specialises in heart and lung disease. Its Chelsea hospital and specialist service information make it an important name for people discussing those care pathways with their clinicians.
Before you decideThe hospital has no A&E department. Children’s heart and lung inpatient services have been moving to Evelina London from May 2026, so follow the current appointment instructions rather than an old location.
Choose by service and referral
Ask your GP or treating team which service is appropriate, whether a referral is needed and what choices are available.
NHS specialist appointments generally require a referral. Compare the relevant department, access needs and journey rather than treating the five names as competing general-purpose options.
What this list does not measure
This is not an inspection report or an outcome comparison.
It does not claim shorter waits, better survival or safer care than hospitals outside the selection. For a personal decision, use current service information and discuss the clinical options with your healthcare professional.
