With NHS waiting lists topping 7.3 million cases in December 2025, the choice between waiting for treatment and paying for it yourself has become a practical financial question for many people. A hip replacement through the NHS might come with a 12 to 24-month wait, while the same procedure privately could cost between £11,000 and £16,000. That gap between time and money is what this article is about.

The private healthcare sector in the UK treated 1.6 million adults in the most recent reported year, and the market has grown 13.8% year-on-year to £8.64 billion. That growth is driven largely by people who don’t have insurance but still want faster access to treatment. The four main routes are private health insurance, self-pay, employer schemes, and medical loans. Each works differently depending on what you need treated, how urgent it is, and what you can afford upfront. Here’s what you actually need to know.
Four Key Takeaways and What “Self-Pay” Actually Means
Most private treatment in the UK still requires a GP referral as the first step. That’s true whether you have insurance or plan to pay yourself. The term you’ll hear most often is self-pay.
What I tend to notice is that people assume self-pay is only for minor procedures. In reality, it covers everything from a £150 consultation to a £16,000 hip replacement. The key is knowing the price before you commit.
What Private Treatment Actually Costs — Procedure by Procedure
The biggest difference between insured and self-pay treatment is how you handle the cost of a major event. Insurance premiums for a 30-year-old in London start around £107 a month for comprehensive cover. Over a year, that’s roughly £1,284. If you never claim, that money is gone. Self-pay means you only pay when you need treatment, but you need to have the funds available.
Here are the typical self-pay costs for common procedures in the UK, based on 2025 data. These are the prices you’d pay directly to a private hospital or consultant.

| Procedure | Self-pay cost range | Typical NHS wait (2025) |
|---|---|---|
| Outpatient specialist consultation | £150 – £400 | 18+ weeks |
| MRI scan | £400 – £800 | 12–24 weeks |
| Cataract surgery (one eye) | £1,500 – £3,500 | 12–24 weeks |
| Hernia repair | £2,500 – £5,500 | 18–36 weeks |
| Knee replacement | £10,000 – £16,000 | 12–24 months |
| Hip replacement | £11,000 – £16,000 | 12–24 months |
The range matters. A knee replacement at £10,000 is a very different financial decision than one at £16,000. Private hospitals publish price lists, but the final cost depends on the consultant you choose, the hospital’s location, and whether complications arise. Always ask for a written quote before agreeing to treatment.
For cancer treatment, the picture changes entirely. Private insurance typically covers the full cost of cancer diagnosis and treatment, which can run into six figures for chemotherapy, radiotherapy, and surgery. Self-pay for cancer is rarely practical unless you have substantial savings or a critical illness policy that pays out a lump sum.
Common Mistakes When Paying for Private Healthcare
Assuming self-pay is always cheaper than insurance
A single outpatient consultation at £150–£400 is cheaper than a year of premiums. But if you need a hip replacement at £16,000, that same insurance policy would have cost you around £1,284 for the year. The mistake is comparing the cost of one visit against the cost of a whole year’s cover. Insurance makes sense when you can’t predict what you’ll need. Self-pay makes sense when you can.
Not checking if your NHS consultant also works privately
Many NHS consultants also see private patients at the same hospital. If you book privately with your NHS consultant, you get continuity of care and they already know your history. The health declaration process for insurance can sometimes delay things, but booking directly with a consultant you already know skips that step entirely. Check the consultant’s profile on the hospital website or call their secretary to ask.
Forgetting about post-treatment costs
Private treatment quotes often cover the surgery and hospital stay, but not follow-up appointments, physiotherapy, or medication. A knee replacement might cost £12,000, but six sessions of private physio at £60 each adds another £360. Ask what’s included in the quote and what you’ll need to pay for afterwards. Some people use a hospital cash plan to cover some of these follow-up costs.
Ignoring the GP referral requirement
You cannot simply call a private hospital and book a hip replacement. Every private consultant in the UK requires a GP referral letter before they will see you. That letter includes your medical history, current symptoms, and any test results. Without it, you’re starting from scratch. Book a GP appointment first, even if you plan to pay privately.
How to Choose Between Insurance, Self-Pay, and Other Options
When private health insurance makes financial sense
Insurance is built for unpredictable, high-cost events. If you’re in your 30s and healthy, a comprehensive policy might cost £45–£70 per month. That covers consultations, diagnostics, surgery, and cancer treatment. The trade-off is that you pay every month whether you use it or not. For a family of four, premiums typically run £120–£200 per month. If you have a history of conditions that need monitoring, insurance can be harder to get or more expensive because of medical underwriting.
When self-pay is the better route
Self-pay works best for a single, predictable procedure with a known price. Cataract surgery at £1,500–£3,500 is a good example. You know the cost upfront, you book the date, and you’re done. No ongoing premiums, no claims process, no excess to pay. The risk is that if something unexpected happens during or after treatment, you pay for that too. Self-pay also requires you to have the full amount available at the time of treatment.
Employer schemes and what they actually cover
Many employer health plans cover in-patient treatment only. That means if you need surgery, you’re covered. But if you need an outpatient consultation, an MRI scan, or physiotherapy, you pay for those yourself. Check your employer’s policy document carefully. Some plans also exclude pre-existing conditions or have a waiting period before you can claim.
Medical loans as a middle ground
If you need treatment now but don’t have the cash, some private hospitals offer financing through medical loan providers. You borrow the cost of the procedure and repay it over 6 to 24 months. The interest rate varies, and the total cost ends up higher than paying upfront. This option is most common for dental work, cosmetic surgery, and fertility treatment.
Upcoming changes to watch
The private healthcare market in the UK grew 13.8% in the last year, and record claims of £4 billion were paid out in 2024. As NHS waiting times remain high, more people are turning to self-pay and insurance. Some insurers are introducing lower-cost policies with higher excesses or restricted hospital networks to keep premiums competitive. If you’re considering insurance, compare policies annually — prices and coverage change.

The Real Trade-Off Between Time and Money
The decision between insurance, self-pay, and other options comes down to one question: can you afford to wait, or can you afford to pay? With 72% of NHS patients waiting over 18 weeks and 139,000 waiting over a year, the time cost is real. But paying £16,000 for a hip replacement isn’t realistic for most people without savings or insurance. The middle ground — a medical loan or a lower-cost insurance policy with a higher excess — is where many people end up. The key is knowing the price before you commit, and understanding what happens if things don’t go as planned.
