As an FCA-authorised broker that has arranged over 800,000 policies, WeCovr is often asked about the future of UK healthcare. In this guide, we model the potential costs of private medical insurance if the nation’s health service was to move to a fully private system overnight.
The National Health Service (NHS) is a cornerstone of British life. For over 75 years, it has provided healthcare free at the point of use, funded by general taxation. But what if that system vanished tomorrow? What if every GP visit, every operation, and every night in a hospital came with a bill?
This isn't a political forecast; it's a thought experiment. By exploring a hypothetical, fully privatised UK healthcare system, we can better understand the true cost of medical care and the value that both the NHS and private medical insurance (PMI) provide today.
At WeCovr, we specialise in helping people navigate the complexities of the current private medical insurance UK market. In this article, we’ll use our expertise to project the costs and consequences of such a monumental shift, shedding light on what you might pay and how it would fundamentally change our relationship with healthcare.
Before we can look to a hypothetical future, we must first understand the present. Currently, the UK operates a dual system. The NHS provides comprehensive care for everyone, while a parallel private sector offers an alternative, often faster, route for specific treatments.
Private Medical Insurance (PMI) is the key that unlocks this private sector for millions. It's an insurance policy you pay for monthly or annually that covers the cost of private treatment for acute conditions that arise after your policy begins.
Critical Information: It is vital to understand that standard UK private medical insurance is designed for new, short-term, curable conditions (acute conditions). It is not designed to cover long-term illnesses you already have (pre-existing conditions) or conditions that cannot be cured (chronic conditions), such as diabetes, asthma, or Crohn's disease.
The primary benefits of using PMI today include:
PMI costs vary widely based on several factors. Here are some illustrative monthly premiums for a mid-range policy in 2025.
| Profile | Estimated Monthly Premium | Key Factors Influencing Cost |
|---|---|---|
| Single, 30-year-old, non-smoker | £45 - £70 | Young, healthy individuals pay the lowest premiums. |
| Couple, 45-year-olds, non-smokers | £120 - £180 | Age is a significant driver of cost; premiums increase as we get older. |
| Family of 4 (Parents 40, Kids 10 & 12) | £160 - £250 | Adding children is often more cost-effective than insuring two separate adults. |
| Single, 65-year-old, non-smoker | £150 - £250 | Premiums rise sharply after the age of 60, reflecting higher health risks. |
These costs are influenced by:
Now, let's step into our hypothetical scenario. The NHS has been disbanded. Healthcare is now a commodity to be purchased. What does this new world look like?
The most immediate change would be the introduction of direct costs for every service. That quick chat with a GP? There's a fee. The blood test your doctor ordered? That's another bill. An ambulance call-out? You'll be invoiced.
Without a nationalised service, the "market rate" for these treatments would become the norm. Here’s a look at the potential uninsured costs for common medical services, based on current private sector pricing.
| Service or Procedure | Estimated Uninsured Private Cost (2025) |
|---|---|
| Private GP Consultation | £90 - £175 |
| A&E Visit (Minor Injury) | £250 - £450 |
| MRI Scan (one part) | £450 - £850 |
| Cataract Surgery (per eye) | £2,800 - £4,500 |
| Hip Replacement Surgery | £13,000 - £16,000 |
| Knee Replacement Surgery | £14,000 - £17,500 |
| Childbirth (Natural Delivery) | £6,000 - £12,000 |
| Cancer Treatment (e.g., Chemo) | £25,000 - £100,000+ per year |
Facing these costs, medical insurance would cease to be a "nice-to-have" and would become an absolute necessity for almost everyone.
A society where people risk bankruptcy from a broken leg or a cancer diagnosis is politically and socially unstable. Therefore, the most probable model a privatised UK would adopt is one of mandatory universal health insurance, similar to systems in Switzerland, Germany, and the Netherlands.
Under this model, every resident would be legally required to hold a basic level of health insurance. The government's role would shift from providing care to regulating insurers and subsidising premiums for the low-paid, unemployed, and those unable to work.
This creates a massive, nationwide "risk pool." By forcing everyone—young and old, healthy and sick—to be insured, the financial risk of high-cost patients is spread across the entire population, keeping average premiums lower than they would be otherwise.
So, what would this mandatory insurance cost? To model this, we considered several factors:
Based on this, WeCovr projects the following monthly premiums for a mandatory, comprehensive health insurance policy in a fully privatised UK.
| Demographic Profile | Projected Monthly Premium (Comprehensive Cover) | Annual Cost vs. Average UK Salary (£35,000) |
|---|---|---|
| Single, 25, Healthy | £250 - £400 | 9% - 14% of gross salary |
| Couple, 40, Non-Smokers | £550 - £800 | 19% - 27% of a single average salary |
| Family of 4 (Parents 40, 2 Children) | £800 - £1,200 | 27% - 41% of a single average salary |
| Single Retiree, 68 (with conditions) | £700 - £1,100 | A significant portion of average state/private pension income |
Key Takeaways from the Model:
The single biggest hurdle in any privatised system is how to care for the millions of people with long-term, expensive health conditions. In the UK, over 15 million people live with at least one chronic condition.
As stated, the current private medical insurance UK market solves this problem by simply excluding them. In a mandatory system, that is not an option. Two mechanisms would be needed:
Both systems are complex and expensive to administer. The ultimate result is the same: the cost of caring for the least healthy members of society is baked into everyone's insurance premium, driving up the price for all.
While our model of a privatised future is a revealing exercise, the reality is that the NHS remains the bedrock of UK healthcare. The question for you today is how to make the current dual system work best for your personal circumstances.
