Quick Answer: The Harley Street Clinic 2026
The Harley Street Clinic is one of HCA Healthcare UK’s flagship private hospitals, located in the heart of Marylebone in central London. It is one of London’s leading private hospitals for cancer care and oncology, cardiac care, and children’s (paediatric) services, with a long-established reputation for complex and specialist treatment.
The hospital sits across several addresses in the Harley Street medical district, with its main hospital at 35 Weymouth Street, London W1G 8BJ, plus a dedicated diagnostic centre and cancer & radiotherapy facilities nearby on Devonshire Street and within the wider Harley Street estate.
Important — don’t confuse it with similarly named businesses. “The Harley Street Clinic” (HCA’s hospital) is different from “The Private Clinic of Harley Street” (a separate cosmetic surgery group) and from the dozens of independent clinics that use a Harley Street address. This guide covers the HCA Healthcare UK hospital specifically.
Services include: comprehensive oncology and radiotherapy, cardiac surgery and cardiology, one of the UK’s leading private children’s hospitals (including paediatric intensive care), complex surgery, diagnostics and imaging, and a broad consultant-led outpatient offering.
Insurance cover: The Harley Street Clinic is recognised by all major UK private medical insurers — but because it’s a premium central London hospital, access often requires a higher plan tier or a London hospital add-on. Always check your specific plan before booking.
This independent 2026 guide covers everything: location and the different addresses, full services, self-pay cost context, how to find a consultant, how UK insurance covers the hospital, and how it compares to other HCA and central London hospitals.
What this guide covers
If you’re researching The Harley Street Clinic in 2026 — whether for cancer care, cardiac treatment, your child’s care, or another specialty, and whether you’re using private medical insurance or paying yourself — this independent guide gives you the full picture. Going Private UK is an independent editorial site with no commercial relationship with HCA Healthcare UK or The Harley Street Clinic. We may receive commission when readers request quotes through health insurance comparison links — this funds independent research but does not affect our analysis.

Not to Be Confused With Other “Harley Street” Clinics
“Harley Street” has been synonymous with private medicine in London for over a century, and dozens of independent clinics use a Harley Street address. This causes genuine confusion. To be clear about what this guide covers:
📝 Which “Harley Street” clinic is which?
The Harley Street Clinic (this guide) — HCA Healthcare UK’s acute private hospital, known for cancer, cardiac and children’s care, main address 35 Weymouth Street, W1G 8BJ.
The Private Clinic of Harley Street — a completely separate cosmetic surgery and aesthetics group with branches across the UK (London, Birmingham, Manchester, Leeds, Glasgow, Bristol). Not the same organisation.
The London Clinic — another major independent private hospital nearby, with consulting rooms at 116 Harley Street; a separate charity-owned hospital (see our London Clinic guide).
Independent Harley Street practices — hundreds of individual consultants and small clinics (dermatology, ENT, cosmetic, fertility, etc.) operate from Harley Street addresses but are independent businesses, not part of The Harley Street Clinic hospital.
The Harley Street Clinic — Location & Addresses
Like many central London hospitals, The Harley Street Clinic operates across several buildings within the Harley Street medical district rather than a single site. This can be confusing when booking, so always confirm the exact address for your specific appointment.
| Facility | Typical Location |
|---|---|
| Main Hospital | 35 Weymouth Street, London W1G 8BJ |
| Diagnostic Centre | Devonshire Street area, Marylebone |
| Cancer & Radiotherapy Centre | Within the Harley Street estate, Marylebone |
| Outpatient & Consulting Rooms | Various Harley Street / Weymouth Street / Devonshire Street addresses |
| District | Marylebone, W1 — the historic Harley Street medical quarter |
🚇 Getting there
The Harley Street medical district is in Marylebone, central London, very well served by public transport. Nearest Underground stations include Regent’s Park, Great Portland Street, Oxford Circus, Bond Street, and Baker Street. Mainline rail connects via Marylebone and Euston. Central London parking is limited and expensive, and the Congestion Charge applies — public transport or taxi is usually easier. Always confirm the exact building address for your appointment, as the hospital spans several locations.
The Harley Street Clinic — Services & Specialties
The Harley Street Clinic is a full acute private hospital with a particular reputation for complex, specialist, and high-acuity care. Its standout specialties are oncology, cardiac care, and children’s services, but it offers a wide consultant-led range:
| Specialty Area | Typical Services |

| Oncology & Cancer Care | Chemotherapy, radiotherapy, surgical oncology, complex cancer treatment, CAR-T and advanced therapies |
| Cardiac Care | Cardiac surgery, interventional cardiology, complex heart procedures |
| Children’s (Paediatric) | One of the UK’s leading private children’s hospitals; paediatric surgery, oncology, intensive care |
| Surgery | Complex and major surgery across multiple specialties |
| Diagnostics & Imaging | MRI, CT, PET-CT, ultrasound, X-ray, advanced imaging |
| Critical Care | Adult and paediatric intensive care units |
| Outpatients | Wide consultant-led outpatient clinics across specialties |
| Women’s Health | Gynaecology, breast care, and related specialties |
For broader UK context on these services see our Private Surgery Hub, Private Diagnostics Hub, private cancer screening guide, and private heart health check guide.

How to Find the Right Consultant at The Harley Street Clinic
Like other private hospitals, The Harley Street Clinic works with consultants under practising privileges — they’re credentialed to treat patients there rather than directly employed. Going Private UK does not endorse or recommend individual consultants; we help you choose using independent criteria.
How to research a Harley Street Clinic consultant
- HCA Healthcare UK’s official consultant finder — confirm a consultant practises at The Harley Street Clinic for your specific specialty
- GMC Specialist Register — verify the consultant is registered for their stated specialty (free public search at gmc-uk.org)
- Sub-specialism check — for complex conditions, confirm the consultant’s specific sub-specialism matches your need
- Procedure volume — ask how many procedures of your type they perform annually; high-volume specialists typically have better outcomes
- Multidisciplinary support — for cancer and complex cases, confirm the consultant works within a multidisciplinary team
- Insurance recognition — confirm your specific insurer recognises the consultant for fee-assured rates
📋 Why we don’t recommend specific consultants
Going Private UK is editorially independent. We do not recommend, endorse, or rank individual consultants because consultant suitability depends entirely on your specific clinical needs which we cannot assess, consultant rosters change, and independent verification through the GMC and HCA’s official directory protects you better than any third-party recommendation. For broader guidance see our how to choose a private consultant guide.
Self-Pay Cost Context at The Harley Street Clinic
As a premium central London hospital specialising in complex care, The Harley Street Clinic sits at the higher end of UK private hospital pricing. Exact costs depend entirely on the procedure, consultant, length of stay, and complexity — these are broad indicative ballparks for context only:
| Service | Indicative Cost Context 2026 |
|---|---|
| Initial Consultant Consultation | £250 – £400 |
| MRI Scan | £500 – £900 |
| CT / PET-CT Scan | £600 – £2,800 |
| Day-Case Procedures | £2,000 – £6,000+ |
| Major Surgery (inpatient) | £10,000 – £40,000+ |
| Cancer Treatment Pathways | Highly variable — quote required |
| Private Room (per night) | £800 – £1,500+ |
💡 Premium London pricing — get a full written quote
Central London hospitals like The Harley Street Clinic are priced at the top of the UK market, reflecting their specialist capabilities and location. For self-pay patients, always get a fixed-price written quote covering consultation, procedure, anaesthetist, hospital fees, intensive care if relevant, and follow-ups — complex care can involve multiple cost components. For many patients, comprehensive private medical insurance that includes central London hospitals works out far more cost-effective than self-paying for major treatment. See our UK private hospital price list and private hospital room cost guide.
UK Private Medical Insurance Cover for The Harley Street Clinic
The Harley Street Clinic is recognised by all major UK private medical insurers — but as a premium central London hospital, it’s typically only covered on higher plan tiers or with a London hospital add-on. This is the single most important thing to check before booking.
⚠️ The London hospital tier issue
Most UK insurers split their hospital lists into tiers, and the premium central London hospitals — including the HCA hospitals like The Harley Street Clinic — usually sit on the top tier or require a London add-on/surcharge. Standard or “guided” plans frequently exclude these hospitals to keep premiums down. Before assuming you’re covered, confirm directly with your insurer that The Harley Street Clinic is on your specific plan. If you want access to HCA London hospitals, you typically need to choose this at the point of buying or renewing your policy. See our detailed guide on which insurers cover HCA London hospitals and does AXA cover HCA hospitals in London.
| UK Insurer | Harley Street Clinic Cover | How to Confirm |
|---|---|---|
| Bupa | Top-tier / London list | Check Extended Choice + London. See Bupa hospital list guide |
| AXA Health | London tier / check plan | See AXA HCA London cover |
| Aviva | Check London surcharge | See Aviva hospital list guide |
| Vitality | London option / check tier | See Vitality hospital list guide |
| WPA | Check plan | See WPA hospital list guide |
| The Exeter | Check plan | See The Exeter hospital list guide |

The Harley Street Clinic vs Other Central London Hospitals
The Harley Street Clinic is one of several premium central London private hospitals. How it compares:
| Hospital | Operator | Known For |
|---|---|---|
| The Harley Street Clinic | HCA Healthcare UK | Cancer, cardiac, children’s care |
| The Wellington Hospital | HCA Healthcare UK | Largest private hospital; neuro, complex care |

The honest verdict on The Harley Street Clinic
The Harley Street Clinic is one of the UK’s leading private hospitals for complex, specialist care — particularly cancer, cardiac, and children’s services. For patients needing advanced treatment with access to leading consultants, intensive care, and cutting-edge therapies, it’s among the strongest options in the country, backed by HCA Healthcare UK’s scale and resources.
The honest practical points: it’s a premium central London hospital, priced accordingly, and spread across several Marylebone addresses — so always confirm the exact location for your appointment. The name causes genuine confusion with the separate “Private Clinic of Harley Street” cosmetic group and the many independent Harley Street practices, so make sure you’re booking with the right organisation.
For insurance customers — the critical point: The Harley Street Clinic typically sits on the top tier of insurer hospital lists or requires a London add-on. Many standard plans exclude it. If access to HCA London hospitals matters to you, you need to choose a plan that includes them — ideally before you need treatment, since you can’t usually add it mid-claim.
The smartest approach: if you want the option of treatment at hospitals like The Harley Street Clinic, compare comprehensive policies that include central London hospitals. The premium difference is often smaller than people expect, and it’s far cheaper than self-paying for major treatment. Compare quotes from 5-star UK insurers here.
