Which is the largest private hospital group in the UK?

Spire Healthcare and Nuffield Health are the two largest by hospital count. Spire operates 39 hospitals and clinics across the UK; Nuffield runs 37 hospitals plus 113 fitness and wellbeing centres. HCA Healthcare UK has 7 hospitals and 50+ outpatient and diagnostic clinics, concentrated mainly in London and Manchester. By revenue, HCA is comparable to Spire despite the smaller footprint, because it focuses on complex, high-acuity care.

Is Spire or Nuffield cheaper for self-pay?

Self-pay prices are broadly similar at Spire and Nuffield for routine procedures — a hip replacement runs £14,000–£17,000 at both. Nuffield publishes more transparent fixed-price packages on their website. Spire often quotes per consultant, so the same procedure can vary by £2,000–£3,000 between Spire hospitals. HCA self-pay tends to run 20–40% higher than Spire/Nuffield because of London-weighted pricing and more complex caseload.

Are Spire, Nuffield, and HCA all CQC-regulated?

Yes. All Spire, Nuffield, and HCA hospitals in England are regulated by the Care Quality Commission and inspected on the same framework as the NHS. As of the latest published inspections, around 80% of Spire and Nuffield hospitals are rated Good or Outstanding. HCA hospitals are predominantly rated Good or Outstanding, with The Christie Private Care, The Lister, and The Wellington consistently leading on cancer and cardiac outcomes.

Which hospital chain do private medical insurance plans cover?

Bupa, AXA, Aviva, and Vitality all have agreements with Spire and Nuffield as standard. HCA is on most insurer networks but is sometimes excluded from cheaper 'guided' or 'directional' plans where the insurer steers you to lower-cost hospitals. Always check your insurer's hospital list before booking — the same procedure at HCA may cost the insurer £3,000–£8,000 more than at Spire or Nuffield.

Which is best for cancer treatment?

HCA Healthcare UK is the strongest of the three for complex oncology. The Christie Private Care (Manchester), Leaders in Oncology Care (London), and London Bridge Hospital all run consultant-led tumour boards, integrated radiotherapy, and access to clinical trials. Spire and Nuffield offer chemotherapy and routine surgical oncology but typically refer complex cases to HCA or NHS tertiary centres.

Which is best for orthopaedic surgery?

Spire and Nuffield both have very high orthopaedic volumes — hip and knee replacements, arthroscopies, spinal surgery — and most consultants split work between NHS and private at one of these two chains. Outcomes for routine joint replacement are comparable. Nuffield has a slight edge on integrated rehab because of its on-site physio and gym facilities; Spire has more theatre capacity for shorter waits.

When to choose Spire

Mid-priced national footprint — you're not in London and want consultant choice
Specific consultant follows you — many NHS consultants do private work at their nearest Spire
Faster access to theatre — Spire generally has higher private theatre capacity than Nuffield
Diagnostic + procedure together — strong outpatient diagnostic + same-site treatment

When to choose Nuffield Health

Transparent fixed-price packages — easier to budget than per-consultant Spire quotes
Post-op rehab matters — gym + physio on site at most hospitals
Charitable model — surplus reinvested in NHS partnerships and prevention
Money Back Guarantee — revision surgery covered if a stated complication occurs

When to choose HCA Healthcare UK

Complex cancer care — The Christie Private Care, LOC, London Bridge are the UK's leading private oncology centres
Cardiothoracic surgery — The Wellington and London Bridge run consultant-led heart programmes
Paediatrics — The Portland is the UK's largest private paediatric and women's hospital
You're in London or Manchester — geographic restriction is the biggest filter
Insurance covers you — most policies include HCA but check 'guided' clauses

Self-pay vs insurance

Self-pay: cheapest at Nuffield's fixed-price packages for routine surgery; ask Spire for written all-in quotes including consultant, anaesthetist, hospital, and follow-ups before committing.
Insurance: all three accept all major insurers, but cheaper "guided" plans (Bupa Select, AXA Health Plan with hospital list) may exclude HCA. Read the small print before paying premiums.
Hybrid: many people fund the consultant + diagnostics privately and revert to NHS for the procedure — particularly cost-effective for orthopaedic and dermatology pathways.

Alternatives

Ramsay Health Care UK — 35 hospitals, similar price point to Spire
Circle Health Group — 50+ hospitals, formerly BMI Healthcare, often the cheapest of the major chains for self-pay
NHS Private Patient Units (PPUs) — embedded within NHS hospitals (Royal Marsden, Guy's, Royal Free), often the cheapest route to top consultants
Independent hospitals — One Welbeck, The London Clinic, Cromwell Hospital — boutique alternatives to HCA

The bottom line

For routine surgery on a budget, Nuffield Health's fixed-price packages are the easiest to compare and book. For mid-market national reach with strong consultant choice, Spire Healthcare has the largest footprint outside London. For complex cancer, cardiac, or paediatric care, HCA Healthcare UK is in a different league but at materially higher prices — viable mainly if your insurance covers it or your case requires the acuity.
