UK Private Hospital Networks Explained
Your private medical insurance policy comes with a hospital list; the recognised hospitals where you’re covered. The list affects both your premium and the kind of facilities and consultants you can access. Here’s a plain-English guide to the major UK private hospital networks and how they fit into PMI policies.
The major networks
Spire Healthcare
A national network of around 40 hospitals across the UK, Spire is one of the largest private hospital groups. Strong general surgical, orthopaedic, and oncology offering, well-distributed geographically.
Nuffield Health
Around 35 hospitals plus a wide gym and wellbeing footprint, Nuffield Health is a not-for-profit, with surplus revenue reinvested into healthcare. Particularly strong in orthopaedics and rehabilitation.
HCA Healthcare UK
A premium group with central London hospitals including The Wellington, Princess Grace, Portland, Harley Street Clinic, and London Bridge Hospital. Specialist strengths include cancer (Leaders in Oncology Care), cardiac care, and complex surgery. The most expensive network; usually only on top-tier policies.
Ramsay Health Care
A national group of around 35 hospitals across the UK, with broad surgical and outpatient capability.
Circle Health Group
Formed by combining BMI Healthcare with Circle, now one of the largest networks in the UK with 50+ hospitals, including some specialist musculoskeletal and oncology centres.
Aspen Healthcare
A smaller, premium-end group with hospitals concentrated in central and southern England.
London-only premium hospitals
Independent or boutique hospitals like Cromwell Hospital (Bupa-owned), King Edward VII’s, St John & St Elizabeth, and the Lindo Wing fall outside the big networks. These are usually only included on premium hospital lists.
How hospital lists work on PMI
Insurers structure hospital lists in tiers, broadly:
Guided / partnership lists
You don’t choose your hospital; the insurer guides you to one based on the procedure. Cheapest premium tier. Typically excludes central London premium hospitals.
Standard lists
A defined list of regional and national hospitals, usually covering most of Spire, Nuffield, Circle, and Ramsay. Excludes most HCA and other premium central London hospitals.
Extended / full lists
Includes most major networks plus access to central London teaching hospitals (HCA, Cromwell). Significantly higher premium.
Premium / extended London lists
Adds further central London premium hospitals. Usually reserved for top-tier individual policies and high-end group schemes.
How to choose a hospital list
Factors to consider:
Where do you live?
If you live within easy reach of a comprehensive Spire or Nuffield, you may not need premium-list access. If your nearest substantial private hospital is in central London anyway, you may need it.
What kind of cover do you need?
For routine surgery and outpatient care, standard lists are usually fine. For complex cancer, cardiac, or specialist surgery, the broader lists open up centres of excellence.
What can you afford?
Stepping up from a standard to a premium list often adds 20-40% to the premium. Worth doing if you’ll use it; not if you won’t.
Where are your preferred consultants?
Some consultants only practise privately at specific hospitals. If you have a strong preference, check which hospital list includes them.
Mid-policy hospital list changes
Most insurers let you upgrade or downgrade your hospital list at renewal. Switching mid-year is usually possible but may trigger underwriting review.
Frequently asked questions
Can I go to any hospital with private cover? No; only hospitals on your policy’s recognised list. Some policies allow out-of-network treatment with the insurer’s prior agreement.
What if my treatment isn’t available at my listed hospitals? Most insurers have an exception process where they’ll fund treatment at an unlisted hospital if it’s not available on your network.
Is the NHS treated the same way? Some policies offer a cash benefit if you choose NHS treatment instead of private; typically £50-£250 per night of inpatient stay.
Are private wings of NHS hospitals included? Often yes. Many NHS-run private patient units (e.g. Royal Brompton & Harefield Private Care, Nuffield Health at Guy’s Hospital) sit on the broader hospital lists.
