The complete guide to private health insurance: what PMI means and the one thing it never covers, real 2026 costs from £28 a month for the young and healthy to the £79.59 national average, the five plan features that buy faster specialist appointments, every UK insurer reviewed, and how to compare policies like someone who has read the small print.
Private medical insurance (PMI) pays for private treatment of new, acute conditions: the consultations, scans, surgery and eligible aftercare that would otherwise mean an NHS wait or a self-pay bill. It buys speed and choice: specialists in days, surgery on planned dates, your pick of consultant and hospital. In 2026 it averages £79.59 a month for an adult (£145.77 for couples, £166.52 for a family of four), from about £28 for the young and healthy.
What it never covers: pre-existing conditions, chronic condition management, emergencies and routine screening. PMI runs alongside the NHS, not instead of it. Below: how it works, what it costs, how to compare, and every guide on this site, insurer by insurer.
PMI stands for private medical insurance, the UK term for health insurance that pays for private treatment of new medical problems. The mechanics in one paragraph: you pay a monthly premium; when a new symptom appears, you see a GP (often the policy’s own virtual GP), get a referral, obtain pre-authorisation from your insurer, and are then treated privately with the insurer paying the bills, subject to your plan’s limits and excess. One myth worth killing: PMI is not only for private clinics. It pays for treatment in private hospitals and in the private wings and private patient units of NHS hospitals. Your policy’s hospital list, not the building’s ownership, decides where you can go. And the consultant you see privately on Tuesday often holds an NHS post on Wednesday: PMI buys the queue, the calendar and the room, not different medicine.
| Covered (subject to plan limits) | Never covered on standard UK policies |
|---|---|
| Specialist consultations for new symptoms | Pre-existing conditions (per your underwriting) |
| Diagnostics: MRI, CT, blood tests, endoscopy | Chronic condition management (diabetes, asthma and similar) |
| Inpatient and day-case surgery, private room | Emergencies: 999 and A&E are NHS work |
| Cancer care (most policies, often excellent) | Routine screening without symptoms |
| Eligible aftercare, physio within limits | Cosmetic treatment, normal pregnancy |
The left column is why people buy PMI; the right column is why some regret it. Nearly every complaint about health insurance traces back to expecting cover from the right-hand side. The boundary rules live in how pre-existing conditions work and waiting periods explained. If what you mainly want is help with everyday costs rather than big-event cover, cash plans vs PMI settles which product you are shopping for.
| Who is covered | 2026 average (mid-tier, £250 excess) |
|---|---|
| Single adult | £79.59/month |
| Couple | £145.77/month |
| Family of four | £166.52/month |
| Healthy 20-something, basic plan | From about £28/month |
Five dials move your number: age (the dominant one; premiums climb steeply from 50), postcode (London and the South East price highest), cover level (outpatient limits especially), excess (raising £100 to £500 typically cuts 15 to 25%), and underwriting. Renewals rise with medical inflation, commonly 6 to 12% a year, which is why the comparison habit pays annually, not once. Model your own number with our cost calculator, see the breakdown by age and insurer in monthly costs explained, and test the whole decision in is it worth it?
The most common reason people buy PMI in 2026 is quicker specialist appointments. Here is the feature list that delivers it, in priority order. One: outpatient cover. Consultations and diagnostics are outpatient work, so a plan with limited or no outpatient cover does not speed up the very thing you are buying for; outpatient limits explained is the most valuable read on this page. Two: a virtual GP service, with same-day video appointments that issue same-day referrals; see best for GP access. Three: direct access, where some insurers let you skip the GP entirely for specific concerns. Four: the hospital list, which decides which specialists are reachable at all; see how hospital lists work. Five: the referral style; open referral vs named consultant is speed and price versus choice. For this goal, a mid-tier plan with solid outpatient cover beats a premium plan with caps.
| Dial | What it decides | The deep dive |
|---|---|---|
| Underwriting | How your medical history is treated | Moratorium vs full medical underwriting |
| Outpatient limit | Whether diagnostics are covered | Outpatient limits |
| Hospital list | Where you can be treated | Hospital list tiers |
| Excess | Premium vs claim-day cost | Excess guide |
| Referral style | Choice vs speed vs price | Guided vs full choice |
| The extras | Mental health, dental, GP access | Per-insurer guides below |
Two quotes at the same premium can differ enormously underneath: a £70 a month policy with full outpatient cover and a £70 a month policy with a £500 outpatient cap are different products wearing the same price tag. That is the whole argument for like-for-like comparison over cheapest-headline shopping. Paying less without gutting the cover: raise the excess, take a guided hospital list, consider the six-week option, right-size the outpatient limit rather than deleting it, and compare at every renewal.

Private medical insurance, or PMI, is a policy that pays for private treatment of new, acute medical conditions: the consultations, scans, surgery and eligible aftercare that would otherwise mean an NHS wait or a self-pay bill. In exchange for a monthly premium, you get faster access to specialists, a choice of consultant and hospital, and private facilities. It runs alongside the NHS, not instead of it: emergencies, chronic condition management and GP registration all stay with the NHS.
In 2026, a single adult averages around £79.59 a month for mid-tier cover, a couple around £145.77, and a family of four about £166.52, with healthy younger adults on basic plans starting from roughly £28 a month. Premiums rise steeply with age. The dials that move your price most are age, postcode, cover level, excess and underwriting. Renewal increases of 6 to 12% a year reflect medical inflation, which is why comparing at renewal matters.
Covered: new acute conditions arising after the policy starts, including specialist consultations, diagnostic scans and tests, inpatient and day-case surgery, cancer care on most policies, and eligible aftercare, subject to your plan’s limits. Never covered on standard UK policies: pre-existing conditions, ongoing management of chronic conditions like diabetes or asthma, emergencies, routine screening without symptoms, cosmetic treatment, and normal pregnancy.
No. PMI pays for treatment in private hospitals and in the private wings and private patient units of NHS hospitals, which insurers include on their hospital lists. Many of the consultants you would see privately also hold NHS posts. Your policy’s hospital list decides where you can be treated.
Five features do the work: outpatient cover, because consultations and diagnostics are outpatient work; a virtual GP service for same-day referrals; direct access pathways, where some insurers let you skip the GP for specific concerns; the hospital list, which decides which specialists are reachable; and the referral style, where open referral trades some choice for speed and lower premiums. For this goal, a mid-tier plan with solid outpatient cover usually beats a premium plan with caps.
It depends on what you are buying it for. It is strongest for people who want certainty of speed, with diagnostics in days and surgery on a planned date, and who would otherwise face self-pay bills of £350 to £900 for an MRI or £11,000 to £18,000 for a joint replacement. It is weakest for anyone expecting it to cover existing conditions, chronic illness or emergencies, which it never will.
Compare six things, not one price: the underwriting basis, the outpatient limit, the hospital list, the excess, the referral style, and the extras that matter to you, such as mental health, dental and GP access. Two quotes at the same premium can differ enormously underneath, which is why a like-for-like comparison through an FCA-regulated broker beats picking the cheapest headline number.
This 2026 guide is independent general information, not financial or insurance advice. Policy terms, prices and benefits vary by insurer and change over time, and average premium figures are indicative market data, not quotes. Health insurance covers new conditions arising after a policy starts, not pre-existing conditions, chronic condition management, routine screening or emergencies; in an emergency call 999. If you compare private health insurance quotes through this site, we may receive a commission from our FCA-regulated partners at no cost to you; this does not influence our guides.
