Three free sources cover most of what's knowable: CQC ratings (safety and management inspections, private hospitals included), PHIN (the official publisher of private-market data: procedure volumes, lengths of stay, patient satisfaction, some fees), and infection/outcome basics in each hospital's CQC report. Read them for patterns, not single scores — and let volume at your procedure carry real weight.
- ✓CQC inspects and rates private hospitals on the same four-point scale as NHS ones.
- ✓PHIN publishes private procedure volumes, lengths of stay and satisfaction — by hospital and consultant.
- ✓Read for patterns across sources; a single score or star rating proves little on its own.
Source one: CQC ratings — and how to read past the headline
The Care Quality Commission inspects every hospital in England — private ones included — and rates them Outstanding, Good, Requires improvement or Inadequate. The headline rating is what everyone quotes; the value is one layer down.
- Read the domain ratings. Each hospital is rated across five questions — safe, effective, caring, responsive, well-led. A 'Good' hospital rated 'Requires improvement' on safe is telling you something the headline hides.
- Read the service-level detail. Ratings differ by department; surgery may be strong where outpatients is weak, or vice versa.
- Check the inspection date. A glowing rating from years ago describes a hospital that may no longer exist in that form. Recent reports beat old ones, whatever the score.
- Skim the report itself for your area of care. Twenty minutes with the surgery section tells you more than the badge on the website.
Source two: PHIN — the private market's official dataset
The Private Healthcare Information Network (PHIN) is the independent body that private hospitals and consultants are required — under a Competition and Markets Authority order — to submit data to. Its website publishes, free, for private care specifically:
| What PHIN publishes | Why it's useful |
|---|---|
| Procedure volumes by hospital and consultant | Volume correlates with outcomes; it's the single most decision-relevant number |
| Lengths of stay for common procedures | Consistently long stays versus peers can signal complications or case-mix |
| Patient satisfaction and some patient-reported outcomes | How treated patients rate the experience and results |
| Fee information for many consultants | Self-pay comparison shopping with actual numbers |
PHIN's coverage is still maturing — not every measure is published for every hospital or consultant, and gaps are common. But it's the only place private-market data is published at all, and checking your procedure and shortlisted hospital there costs nothing.
Cover for the hospitals you'd actually choose
Infections and outcomes: the basics that generalise
You don't need epidemiology to use infection and outcome data sensibly. CQC reports cover infection prevention; hospitals publish infection metrics with varying enthusiasm; and for surgery, patient-reported outcome measures (PROMs) exist for some common operations. Three principles keep you honest:
- Rates need denominators. 'Two infections last year' means nothing without knowing how many procedures. Small hospitals produce noisy numbers — one bad case can swing a small denominator wildly.
- Case-mix explains a lot. Hospitals taking sicker, more complex patients can show worse raw numbers while delivering better care. Adjusted figures beat raw ones where published.
- Trends beat snapshots. A hospital improving over three inspections is often a better bet than one coasting on an old 'Outstanding'.
A method, not a league table
We deliberately haven't scored hospitals for you — single rankings compress away exactly the detail that matters for your procedure. Instead, the evening's homework, in order: CQC rating and domains for each shortlisted hospital; the recent report's section on your care area; PHIN volumes for your procedure at that hospital and consultant; satisfaction data where published. Then triangulate: one weak signal is a question to ask, several pointing the same way is an answer.
Data narrows the field; the consultation closes it. Pair this homework with our checklist for choosing the consultant — and remember your policy's hospital list defines which of these hospitals you can actually use.
Frequently asked questions
Where can I find quality data on private hospitals?
Two free sources cover most of it: CQC inspection ratings and reports (private hospitals are inspected on the same scale as NHS ones), and PHIN — the official publisher of private-market data, with procedure volumes, lengths of stay, satisfaction scores and some fees by hospital and consultant.
What does PHIN actually publish about private hospitals?
Under a CMA order, private hospitals and consultants must submit data to PHIN, which publishes procedure volumes, lengths of stay, patient satisfaction and some patient-reported outcomes and fee information — searchable free by hospital, consultant and procedure. Coverage is still maturing, so expect gaps.
How should I read a hospital's CQC rating?
Go past the headline: check the five domain ratings (especially 'safe'), the service-level ratings for your care area, and the inspection date — old ratings describe old hospitals. Twenty minutes in the actual report's relevant section beats the badge on the website.
Are hospital infection rates a reliable quality signal?
Only with care. Rates need denominators — small hospitals produce noisy numbers where one case swings the figure — and case-mix matters, since hospitals taking complex patients can show worse raw numbers while delivering better care. Prefer adjusted figures and trends over snapshots.
What can't hospital quality data tell me before I choose?
How the hospital handles deterioration in your case: escalation, critical-care arrangements and NHS transfer agreements, which vary especially at smaller private units. That's a consultation question — 'if things go wrong, what happens and where do I go?' — not something any published dataset answers.
